The online Meteorite Bulletin Database now allows searching for and listing meteorites 70 whose description includes oxygen isotopic composition. This is accessible by selecting 71 "oxygen isotopes" instead of "normal table" in one of the display menus.

73

The online Meteorite Bulletin Database also allows searching for meteorites that have 74 information about their strewnfield characteristics (masses and coordinates of individual 75 stones). As to date, this information is available, at least partly, for 31 meteorites.

76 Submissions of new data on the strewnfields of witnessed falls are welcome, and may be In accordance with §7.1 of the Guidelines for Meteorite Nomenclature, type specimens 114 of all new meteorites "... must be deposited in institutions that have well-curated meteorite 115 collections and long-standing commitments to such curation." The minimum mass of a 116 type specimen should be 20% of the total mass or 20 g, whichever is the lesser amount.

117 For larger meteorites, the Nomenclature Committee strongly recommends the following:

118 for 0.4 to 10 kg samples, at least 5% of total mass should be deposited in an approved 119 repository, and for meteorites > 10 kg, at least 500 g should be deposited. However, these 120 larger type specimen requirements are mandatory for meteorites declared to be in Special south and north to La Palmera in San Carlos. The first piece recovered, 1152 g, crashed through a house at 10°23'29.03"N, 84°20'28.58"W. A dog house was hit by a 280 g piece at 10°24'9.35"N 84°21'51.26"W. The BRAMON (Brazilian Meteors Observation Network), UNESP (São Paulo State University) and USP (University of São Paulo) teams determined the atmospheric trajectory of the bolide from four security videos and dashcam cameras. The bolide had an entry angle of 73° relative to the ground, traveling 20.7 km in the 4-s analyzed interval, with an atmospheric velocity of 14 km/s. Analysis shows a projected elliptical strewn-field with major axis length of 6.3 and minor axis of 3.3 km. Hundreds of stones were recovered within the projected strewn-field. The bolide orbit was determined, with the follow preliminary elements: semi-major axis 2.7 AU, eccentricity 0.63, inclination 3.09°, pericenter longitude of 185.3° and ascending node 33.4°. Current total recovered mass is around 27 kg, of which ~11 kg was collected before rain fell over the fall site. Physical characteristics: (L. Garvie, ASU) Hundreds of fusion-crusted stones ranging from 0.1 to 1868 g. Stones under ~50 g are typically angular to blocky and lack regmaglypts. Also found were several plate-like, oriented stones. For example, one oriented plate is 13 cm wide and 1 cm thick. Many stones are oriented with a domed leading edge and well-developed roll-over lip along the rim of the trailing edge. Larger stones, especially those near 1 kg, show broad regmaglypts, some well developed. The fusion crust on several of the trailing edge surfaces is iridescent. Prerain material crushed in a few ml of water emits a powerful "Murchison-like" odor, though with a more prominent compost-like scent. Petrography: (L. Garvie, ASU) The interior of the stones is uniformly dark gray and studded with small light-colored speckles. Stones are brecciated and dominated by two lithologies: chondrule poor, constituting ~80 areal% of the broken surfaces examined (~2 kg of material), and chondrule rich. Chondrules constitute ~10 areal% of the chondrule-poor lithology and ~40 areal% in the chondrule-rich lithology. Some broken surfaces show clasts of the chondrule-rich lithology in the chondrulepoor type. Clasts with lower chondrule to matrix ratio also present; for example, one 3 g half stone shows <1 areal% chondrules. A probe mount of the dominant chondrule-poor lithology (sample area 1.5 × 2.2 cm) shows scattered small chondrules (mean 275 μm, n=40), with prominent fine-grained rims. Rare chondrules to 2 mm. Fe-Ni metal, which is Cr-bearing, was only found as rounded grains in one 100-μm type I chondrule. The section contains several Al-rich CAIs to 300 μm. The matrix is dominated by two components of roughly equal proportions: anhedral clumps (typically 50 microns) that are Fe and S rich (e.g., 37.5 wt% Fe and 5.8 wt% S, with microprobe total of 93%), surrounded by fine-grained material poorer in Fe and S (e.g., 12.8 wt% Fe, 13.9 wt% Mg, and 0.5 wt% S, with microprobe total of 80.0%). Powder XRD from five stones (one chondrule rich) shows patterns dominated by serpentine. In two stones, the serpentine 001 reflection sits on a broad peak centered at 0.843 nm. Reflections for tochilinite and calcite occur in all patterns. The intensities of olivine and pyroxene reflections were generally low, but most prominent in the chondrules-rich stone.

Ayagoz

~47°50'E, ~80°26'E Semipalatinsk, Kazakhstan Find: 2000 Classification: Iron meteorite (IIIE) History: A large iron meteorite was found in prairie by a horse rider in 2000, ~12 km south of Ayagoz. A 38.9 kg piece and a 7 kg piece were brought to two different dealers by Jevgenijs Suhanovs in Ayagoz city. Samples from both pieces were analyzed to confirm they came from the same meteorite.

Physical characteristics:

The main mass is covered with light-brown rust. Cut surface reveals a fresh metallic interior. Petrography: Examination of etched sections reveals a coarse octahedrite structure (Og) with kamacite bandwidth 1.35±0.37 mm (N=15). Neumann bands are common. Kamacite displays epsilon-structure. Black plessite is common. Notable minerals include schreibersite (common), chromite, troilite, daubreelite. Geochemistry: (M. D'Orazio, DST-PI): Composition of the metal (ICP-MS; D' Orazio and Folco, 2003) is Ni=8.79, Co=0.484 (both in wt%), Cu=113,Ga=17.6,Ge=35,As=4.9,Mo=7.1,Ru=5.4,Rh=1.57,Pd=3.4,Sn=0.07,Sb=0.15,Ir=0.30,Pt=6.7,Au=0.83 (all in ppm). Classification: Iron (IIIE) Specimens: Type specimen and two polished sections at CEREGE History: The main mass was found on the surface resting in decomposing leaves surrounded with wild native blueberry bushes; other fragments were found similarly, covered with leaves with margins encased in soil, and some were found beneath the surface 1-4" deep. The first 1113 g fragment was found on August 18, 2018, and the main mass was discovered on September 11, 2018; remaining fragments were found between those date through 2018. All fragments were found in close proximity, in an area approximately 25' × 5', with smallest fragments toward one end. Physical characteristics: Specimen has a smooth surface with shallow regmaglypts. The main mass is 28 × 20.5 × 13 cm in size and appears oriented (shield orientation), with frothy roll over lip on one side. Some fragments have bits of remnant fusion crust, others show secondary fusion crust. White chondrules visible on most broken surfaces. Petrography: In addition to olivine and low-Ca pyroxene, there is minor Ca pyroxene (Fs 6.9±0.7 Wo 44.2±0.7 ; n = 2) and plagioclcase (Ab 83.1±0.7 Or 5.7±0.6 ; n = 6). Olivine and low-Ca pyroxene are homogeneous. Very few low-Ca pyroxene grains exhibit polysynthetic twinning. Chondrules are readily discernable and include the following textural types: BO, RP, PO, PP, POP, GOP. Only about 10-15% of the olivine grains show undulose extinction. There are no planar fractures. There are no coarse metal grains. All of the metallic Fe-Ni has been altered to limonite/goethite. There are a few feathered troilite grains remaining; also present are minor patches of clay minerals at the boundaries of mafic silicate grains. There is moderate silicate darkening in the specimen due to the presence of thin silicate-opaque veinlets. Also occurring are 30-40-µm-size chromite-plagioclase assemblages with 2-5-µm-size chromite grains. There are also small chromite veinlets containing plagiolcase patches within some olivine grains. The rock appears to have been shocked and annealed.

Benenitra

23°26.786'S, 45°4.692'E Toliara, Madagascar Confirmed fall: 27 July 2018 Classification: Ordinary chondrite (L6) History: Reports of a meteor that detonated in a loud explosion, and stones falling from the sky into the town of Benenitra (pop. ~30,000) on the evening of July 27, 2018, were received by a visiting geologist, Timothy Marais, on July 30, 2018. He was shown photographs and several small fragments, two of which he purchased, weighing 99 and 14 g. Roger Gibson and Lewis Ashwal in the School of Geosciences at the University of the Witwatersrand confirmed a meteorite origin for these specimens using petrographic analysis and EMPA. Confirmation of the date and time of the fall was obtained independently when an upper atmosphere infrasound event was identified on a bearing south-southwest of the CTBTO station IS33 near Antananarivo, Madagascar, at 17h16 GMT on July 27 by Dr. Andry Ramanantsoa (Laboratory of Seismology and Infrasound, University of Antananrivo). A weak ground tremor at approximately 17h17 GMT was identified in the data from the seismograph at the Sakaraha (SKRH) station approximately 80 km northwest of Benenitra by Dr Ranto Raveloson (Wits), and was interpreted to be related to the airburst. Magnetic susceptibility measurements were performed by Prof. Susan Webb (Wits). Physical characteristics: Two broken fragments containing small remnants of bluish-black to brown-black fusion crust and weighing 14 g and 82 g (after thin sectioning) consist of a light-gray matrix with disseminated metal (<1 mm) and some visible chondrules (<5 mm). The edge of the larger fragment, which contains a thin (<0.5 mm), dark-gray melt vein, was sectioned. Photographs taken by local residents show more than a dozen other fragments ranging in mass from ~100-1000 g; these show mostly intact fusion crusts with only limited chipping of edges. Samples range from subangular to subrounded to disc-shaped, with both sharp and rounded edges. Fusion crusts on these samples are generally smooth, with a few shallow regmaglypts. Petrography: (L.D. Ashwal and R.L. Gibson, Wits) Modal abundances: 50% olivine, 25% low-Ca pyroxene, 5% high-Ca pyroxene, 10% feldspar, 7% troilite, 2% kamacite, 1% taenite, and trace amounts of chromite and a silica-rich phase. Recognizable chondrules range in size between 1 and 4.5 mm in diameter, and include porphyritic olivine and/or pyroxene, barred olivine, radial pyroxene and cryptocrystalline types, although their original textures have been variably modified by secondary thermal effects. Feldspar is almost entirely crystalline, and occurs as irregular grains up to 100 μm across, many of which display twinning. Pyroxenes are untwinned, and most grains exhibit straight extinction, although minor undulatory extinction is present in some grains. Low-Ca pyroxene shows parallel extinction with respect to cleavage traces. High-Ca pyroxene occurs as irregular grains up to 20 μm across; exsolution lamellae were observed in a few grains. Shock features include planar and irregular fractures in olivine, undulatory extinction in feldspar and pyroxenes, and anastomosing opaque shock veins up to 75 μm thick. Geochemistry: Mineral compositions: (L.D. Ashwal and A. Ziegler) Olivine (Fa 24.0±0.8 ), low-Ca pyroxene (Fs 20.4±0.9 Wo 1.4±0.4 ), high-Ca pyroxene (Fs 8.0± 0.8 Wo 42.4±1.0 ), feldspar (Ab 79.1±3.1 An 13.3±1.9 Or 7.6±1.5 ), troilite (Fe = 63.3±0.2, S = 36.5±0.3), kamacite (Ni = 5.7±0.7; Co = 0.85±0.05), taenite (Ni = 27.8±1.0).

Colgate

47.25°N, 97.66°W North Dakota, United States Find: 1999 Classification: Ordinary chondrite (H4) History: A single 39 kg stone was found in 1999 by Tod Erickson while removing rip-rap from his home basement excavation, in Colgate, North Dakota. These rocks had been gathered from local farmers rock piles to fill the basement excavation so the walls would not collapse, as the owner was not going to put a structure on it for some years. When removing the rocks before construction, Tod Erickson found the meteorite. He noted its unusual color and weathered surface, and brought it to UND.

Jalangi

24°05'55''N , 88°41'28''E West Bengal, India Confirmed fall: 2012 Jul 08 (05:15 AM IST) Classification: Ordinary chondrite (L5/6) History: According to local observers, the meteorite came from the southwest, with repeated detonating and whizzing sound. The stone fell on soft soil in a jute field, making an impact pit of about six inches in diameter and eight inches in depth. From the recorded data, it appears that the meteorite fragmented at least two to three times before hitting the ground, indicating the existence of more pieces of the same meteorite. GSI officers searched the locality for additional fragments, but could not find any. It may be possible that some pieces were lost in the adjacent Jalangi or Ganges river. The meteorite was taken into the custody of the local police station within three hours of the fall. The District Magistrate and the Superintendent of the Police, Murshidabad district, West Bengal both were contacted by the Director, Central Petrological Laboratories (CPL), GSI, Central Headquarters, Kolkata-700016 to confirm the news about the meteorite fall. The State Government officers agreed to hand over the sample to GSI. Two officers from GSI, Dr. M. Moitra and Dr. S. Nandy, Senior Geologists, immediately rushed to the spot and collected the meteorite piece weighing about 2 kg from the State Government officers (BDO, Jalangi Block and OC, Jalangi Police Station) on 10 July 2012 (Source: Geological Survey of India, Meteorite Fall Near Jalangi, Murshidabad, W. Bengal on 08. 07.2012., www.portal.gsi.gov.in/gsiImages/information/meteorite_fall_jalangi.pdf).

Physical characteristics:

The meteorite is roughly pyramidal in shape, with a flat base and four complete surfaces (long axis ~ 11 cm), covered almost fully by thin black to brown colored fusion crust (thickness ~1-2 mm). The surfaces are smooth, well ablated, with traces of flow lines. Well-developed surface grooves and regmaglypts are observed. A few shallow regmaglypts, along with one slightly deep and compound variety, was noted on frontal surfaces. A number of well defined, visible chondrules and minute metallic specks were also recorded. Anastomosing thin opaque melt veins and veinlets were also observed. Petrography: This meteorite is composed of olivine + orthopyroxene + feldspathic glass + Fe-Ni metals (kamacite and taenite) + troilite ± magnetite ± merrillite ± apatite. The chondrules are olivine and orthopyroxene, with the interstitial spaces (mesostasis) occupied by feldspathic glass ± pyroxene. The size of chondrules varies from 300-1000 μm (diameter). The shape of chondrules varies from near circularelliptical to sub-elliptical and angular. Chondrules types are Barred Olivine (BO), Porphyritic Pyroxene (PP), Porphyritic Olivine (PO), Porphyritic Olivine Pyroxene (POP) and Granular Olivine (GO), and individual chondrule margins are moderately well delineated. Matrix is relatively fine grained and thoroughly recrystallized. Matrix:chondrules ~60:40. Matrix is brecciated in places. Fragments of olivine and orthopyroxene are enclosed within opaque melt veins (length >> width; maximum width of the vein ~1 mm). Numerous metal (Fe-Ni) droplets (micrometer to submicrometer scale) are confined within these melt veins / veinlets. The feldspathic melt glass (plagioclase composition) is relatively fine grained, patchy and dessiminated in the matrix. Rarely it also forms glassy chondrules (diameter ~400 μm). Geochemistry: Olivine, Fa 24-27 Fo 73-76 ; clinoenstatite, En 74.8-77 Fs 21-23.4 Wo 1-2 ; clinopyroxene (pigeonite), En 72 FS19.3Wo 8.7 ; and feldspathic glass (albite to oligoclase), Ab 75-85 An 9.4-21 Or 3-8.6 with FeOT content <= 1.00 wt%). Kamacite contains Fe ~88-93% and Ni ~7-12%; taenite contains Fe ~45% and Ni ~55%. Classification: Different textural variants of olivine and orthopyroxene exhibit near consistent mineral chemical compositional range (XMg) suggesting Jalangi is an equilibrated ordinary chondrite (L5-6). Specimens: The District Magistrate and the Superintendent of the Police, Murshidabad district, West Bengal, India both were contacted by the Director, Central Petrological Laboratories (CPL), Geological Survey of India, Central Headquarters, Kolkata-700016 to confirm the news about the meteorite fall.

Karpovka

48°40.11'N, 43°46.51'E Volgogradskaya oblast', Russia Find: May 2007 Classification: Ordinary chondrite (L5) History: A single stone was found by S. B. Tarasov and P.A. Gordeev 8-10 km from the village of Karpovka in the Volgograd region. During a picnic, they had noticed an interesting stone in a small depression on the ground.

Physical characteristics:

The meteorite has a dark-brown fusion crust and is slightly covered by iron hydroxides. Petrography: (Ivanova M.A., Vernad): The meteorite consists of chondrules, chondrule fragments, and matrix. The chondrules range in size from 0.3 to 0.8 mm in diameter, averaging 0.65 mm. The chondrule margins are indistinct. The meteorite contains many textural types of chondrules including BO, PO, POP, and PP. The main minerals are olivine, pyroxene, FeNi-metal, sulfides, chromites and iron hydroxides. Geochemistry: Mineral compositions and geochemistry: Olivine Fa 24.9 ; and orthopyroxene Fs 22.0 Wo 1.5. Classification: ordinary chondrite (L5), W2, S2. Specimens: One sample of 71.6 g, three fragments of 3 g in total, and two thin sections are on deposit at Vernad. S. B. Tarasov and P.A. Gordeev hold the main mass of the meteorite. Surface is covered with an orange-brown weathering rind that varies from 0 to approximately 2 mm in thickness. Remnant patches of brown-black fusion crust showing polygonal shrinkage cracks are present. Petrography: (M. Hutson, Cascadia) In thin section, many indistinct chondrules are visible. Phases observed include olivine, low-Ca orthopyroxene, plagioclase feldspar, high-Ca clinopyroxene, maskelynite, Fe-Ni metal, troilite, chromite, copper, merrillite, chlor-apatatite. While the majority of feldspathic material is crystalline feldspar, areas of chromite-plagioclase/glass intergrowths, and maskelynite were observed. Silicates display bimodal coloring: areas containing coarser silicates have a slight yellow staining; fine-grained silicates appear gray. Three irregularly shaped areas stand out in appearance from the rest of the section, and contain coarse (>=100 microns) yellow-stained silicates, including twinned plagioclase feldspar intimately mixed with approximately equal amounts of similarly-sized opaque minerals. Troilite is noticeably more abundant than Fe-Ni metal, and shows a slight change in color along fractures. Approximately 50% of the metal has been replaced by iron hydroxides. Geochemistry: Mineral compositions and geochemistry: Olivine (Fa 25.7±0.6 , N=31), low-Ca orthopyroxene (Fs 22.0±0.6 Wo 1.4±0.2 , N=21), high-Ca clinopyroxene (Fs 8.5±0.5 Wo 45.2±0.3 , N=7), plagioclase feldspar (Ab 82.9±1.9 Or 4.6±1.4 , N=14), maskelynite (Ab 71.6±1.2 Or 10.5±0.9 , N=12). Classification: Ordinary chondrite (L6) based on olivine and low-Ca orthopyroxene contents and texture. May be paired with Thomson (L6), which was observed to fall in 1888 roughly 39 km to the northwest, or more unlikely to Claxton (L6), which was observed to fall in 1984 roughly 127 km to the southeast. Geochemistry: Using a 50 mg fragment, rare gas analyses were made at KyuU. The Ne-21 cosmic-ray exposure age is 25.1±0.6 Ma, and the K-Ar gas retension age is 4.4±0.2 Ga. Classification: L6 Specimens: NMNS: 81 g for display, 20 g for type specimen; NIPR: 1 polished thin section, 1 polished mount Korla 001 41°33'55.04"N, 86° 41'41.39"E Xinjiang, China Find: 19.

Ksar El Goraane

32°11'13.2''N, 003°42'04.6''W Draâ Tafilalet, Morocco Confirmed fall: 28 October 2018 22:30 GMT+1 Classification: Ordinary chondrite (H5) History (H. Chennaoui Aoudjehane FSAC, M. Aoudjehane): On October 28th, 2018 around 22:30 (GMT+1) a fireball was spotted by many people from the southeastern and eastern parts of Morocco. The sighting was reported to H. Chennaoui the following day by Y. Oulmaleh who went to the fall site, then by A. Bouferra. A field mission was organized by H. Chennaoui and M. Aoudjehane on November 11, 2018. to the fall area to record the coordinates of recovered pieces and the testimonies of local inhabitants. M. Touhami El Hafidi from Errachidia helped with the field work. Hammou Oubalaid, a shepherd who was out of his tent, described a very shiny light first, yellow then red, relatively low in the sky. It was coming from the east and headed west in the direction of Kaddoussa barrage. It was followed by 5 sonic booms, then a whistling sound that lasted 1 second, followed by a noise comparable to the unloading of a truck of rocks for about 5 s. The sound had awakened his sheep. Mohamed Oubalaid was inside his tent with his wife and his children when they saw a very bright illumination similar to daytime entering the tent. Then they heard 5 sonic booms. Then they heard many muffled sounds like rocks collapse. Many people from the village Ksar El Goraane and the area of the fall reported the same details on the fireball sighting: shiny like the sun, a yellow color, followed by red, between 4 and 5 sonic booms, and the whistling and noises that followed. Zaid Bouidergi, a meteorite hunter, was in Errachidia for the annual exhibition. He was outside and saw on October 28 around 22:30 a brilliant fireball on the North East of Errachidia that went out after a few seconds. A day after, October 29, in the morning, the first piece, weighting at 185 g, was recovered by Lahcen Oubalaid very close to his tent and around 5 km east of Ksar El Goraane village (N32°11'13.2''; W003°42'04.6'' Alt 1169 m). On the same day, other pieces were collected. Many Moroccan hunters went there to search for more. 5 g were found by Lahcen Oubalaid and 32 g were found by Addi Oulgaddou from Boudnib. Many small pieces were found in the Essnam plateau. A few days later, a 350 g piece was found SE of Ksar El Goraane village by Abderrahim Rahoui. The plateau where most pieces were found is called Izanarzen plateau, E of Ksar El Goraane village, S of Jebel Tabouaroust lakbir and close to Jebel Tabouaroust Essghir. The strewnfield is around 15 km from the ENE to WSW direction. Physical characteristics: (H. Chennaoui Aoudjehane, FSAC) Complete pieces of 350 g, 32 g and 5 g totally covered by black matte to a bit shiny fusion crust. Small pieces show primary and secondary fusion crust.

Mhabes el Hamra

26.2269568°N, 7.8181461°W Tiris Zemmour, Mauritania Probable fall: 2018 Dec 23 Classification: Ordinary chondrite (H4/5) History: Three shepherds (Salek Mohamed, Sidi Ahmed Taleb and Baji Ayoub) were searching for desert truffles in the Tiris Zemmour region of northern Mauritania on December 23, 2018, when they heard a loud sonic boom at 9:30 am.

Natun Balijan

27.856°N, 95.878°E Assam, India Fall: 2017 Jun 05 (04:30 PM IST) Classification: Ordinary chondrite (L4) History: Eyewitnesses reported that the Sadiya meteorite fell at about angle of 60º in the S15ºW to N15ºE direction. Detonating sound was heard and the meteorite fell on cultivated land (older flood plains) of the Lohit river. The depth of penetration was about 45 cm and a pit of ~40 cm diameter was formed. The diameter of the pit gradually narrows to about 12 cm with depth. One piece of sample was retrieved from the fall site. Shri Somnath Sharma, Director (Geology), State Unit: Assam, GSI, North Eastern Region (NER), Guwahati-781005, Assam, India obtained the sample from the office of the Deputy Commissioner (Govt. of Assam), Tinsukia district, Assam, India.

Physical characteristics:

The meteorite is nearly spherical (diameter ~15 cm), covered with well-preserved fusion crust (thickness ~1-2 mm), and has near rounded edges. Well-developed surface grooves and regmaglypts are present. Chondrules are also visible to the naked eyes. Petrography: This meteorite is composed of olivine + orthopyroxene + clinopyroxene + feldspathic glass + Fe-Ni metals (kamacite and taenite) + troilite ± magnetite ± merrillite. The chondrules contain olivine and orthopyroxene, with interstitial spaces (mesostasis) occupied by feldspathic glass + feather-like clinopyroxene. The size of chondrules varies from 400-1000 μm (diameter). The shape of chondrules varies from near circular-elliptical to sub-elliptical and rarely as angular. Chondrule types include Barred Olivine (BO), Porphyritic Pyroxene (PP), Porphyritic Olivine (PO), Porphyritic Olivine Pyroxene (POP) and Granular Olivine (GO), and individual chondrule margins are moderately well defined. Matrix is relatively fine grained and thoroughly recrystallized. Geochemistry: Olivine, Fo 73-75 Fa 25-27 ; clinoenstatite, En 69-76.7 Fs 22-30 Wo 1-4 ; clinopyroxene (augite -diopside), Wo 27-48.8 En 43.7-59 Fs 7.3-13.4 ); and feldspathic glass (albite to oligoclase), Ab 79.4-86 An 10-11 Or 4-10 with FeO T content <= 1 wt%.). Kamacite contains Fe ~84-93% and Ni ~6.5-16% , and taenite contains Fe ~46% and Ni ~ 54%. Classification: Different textural variants of olivine and orthopyroxene exhibit near consistent mineral chemical compositional range (X Mg ) suggesting Natun Balijan is an equilibrated ordinary chondrite (L4) with localized chemical inhomogeneity. except for some ragged breaks. A third parallel crack bisects the thickness. The sides are quite flat and at right angles to the parallel surfaces. The exterior appears to be entry ablated and wind and sand polished except for the breaks. There is no caliche. Petrography: (D. Sheikh, FSU) Small chondrules (~150±50 µm) and rare CAI (~100 μm) are set in a dark-colored matrix. Sample contains olivine, orthopyroxene, troilite, Fe-oxides, and rare Fe-Ni metal. Geochemistry: Olivine (Fa 32.6±14.3 , range Fa 14.8-52.3 , n=15), Low-Ca Pyroxene (Fs 3.3±1.6 Wo 1.4±0.6 , range Fs 1.2-5.9 Wo 0.7-2.6 , n=21). Classification: Carbonaceous chondrite (CO3). Specimens: 22 grams at UCLA; main mass with Nick Gessler.

Northwest Africa 2191 (NWA 2191) (Northwest Africa) Purchased: Jan 2018 Classification: HED achondrite (Eucrite, monomict) History: The meteorite was exported from Morocco to Tucson where it was purchased by N. Gessler. Physical characteristics: About 4/5 of the surface was fusion crusted; 1/4 was covered with caliche. Cut surfaces show the groundmass has a distinctive, palegreenish grey color, except where broken by abundant (~5%) millimeter-sized patches and streaks of root-beer brown, likely oxidization zones around former scattered Fe-metals. Petrography: The sample shows very limited, localized brecciation. It consists dominantly of pyroxene and plagioclase, along with subequal proportions of silica, olivine and ilmenite, and lesser troilite, metal (and more abundant Fe-oxide apparent products of metal weathering) and apatite. Grain sizes are diverse from place to place. Grain lengths are locally up to1 mm but more commonly a small fraction of that, and several enclaves consist of dominantly equant grains of order 5-10 µm across. The original igneous texture was dominantly subophitic, but was uneven and is now somewhat obscured due to thermal metamorphism (and possibly metasomatism), which manifests as thin exsolution lamellae mainly in pyroxene cores, complex "cloudiness" of microinclusions, and localized annealing textures. Petrography: The texture is an immature regolith breccia, gradational with polymict nonregolithic (fragmental) breccia. A finite but very sparse abundance of regolithic spheroids (two identified in a large thin section) is the main indication for an immature regolith breccia. The groundmass is mafic-rich. Clasts vary in mode from Ti-poor basaltic to anorthositic (9/10 plagioclase, granulitic). Pyroxene is the dominant mafic silicate; and in the groundmass, in the basaltic clasts, and in relatively coarse mineral clasts, mostly shows a similar fine, roughly µm-scale, exsolution. Lithic clast textures include vitrophyric, fine-scale poikilitic (impact melt?), granulitic, and medium-grained basaltic. One unusual clast, 0.4 × 0.2 mm, consists of a symplectitic intergrowth of roughly 50% ferroan olivine, 35% silica and 15% augite (with very fine-scale exsolution lamellae of low-Ca pyroxene) and 0.5% ilmenite. Geochemistry: On the pyroxene quadrilateral, compositions (28 analyses) scatter evenly across the space bounded by Fs 22 Wo 9 , Fs 54 Wo 6 , Fs 52 Wo 21 and Fs 38 Wo 39 ; the last being the pyroxene of the olivine-silica-pyroxene simplectitic clast. Pyroxene FeO/MnO averages 65.5. The olivine of the sympectitic clast is uniformly Fa 83. Olivine elsewhere is as magnesian as Fa 28. Plagioclase (8 analyses) ranges from An 88 to An 97 , the latter extreme coming from the same poikilitic highland clast that yielded the Fa 28 olivine. Two glassy spheroids have VLT-mare compositions similar to glasses in Yamato 793274. The bulk composition, determined by INAA and fusedbead EPMA applied to 2 chips totaling 760 mg, has 18 wt% Al 2 O 3 , 12.2 wt% FeO and Mg/(Mg+Fe) = 57 mol%, a combination that (along with the spheroids, and the compositional spread and slight exsolution in much of the pyroxene) suggests a significant VLT-mare component. The bulk TiO 2 is only 0.58 wt%. The bulk-rock concentration of the arch incompatible element Th is 1.0 µg/g. Geochemically as well as petrographically, this sample strongly resembles the first highland-mare mixed breccia, Yamato 793274. Classification: Lunar mixed highland-mare breccia Specimens: Main mass with Gessler, type specimen at UCLA.

Petrography:

The meteorite displays a dark-grayish interior and is composed of chondrules (mean diameter about 0.9 mm; up to 2 mm sized), up to 5 mm sized CAIs, and olivine amoeboids all set into a dark fine-grained matrix. Type II chondrules are absent. Some chondrules show reddish staining due to terrestrial weathering.

Purchased: 2016 5 Classification: HED achondrite (Eucrite, unbrecciated) History: Purchased by Miao Bing-an in 2016 from Morocco. Physical characteristics: A black fusion crust is visible on the surface of the meteorite, and some of the fusion crust is covered by yellow-brown soil. In addition, the hand specimen is unbrecciated and has weak magnetic properties (i.e., a magnet is weakly attracted to the meteorite). Petrography (B. Miao, C. Zhang, GUT): The rock structure is igneous but not brecciated. Many types of minerals were found in this meteorite, such as Low-Ca pyroxene, high-Ca pyroxene, plagioclase, SiO 2 , metal-Fe, chromite, ilmenite, troilite, rutile and baddeleyite.

Physical characteristics:

The surface of the unbrecciated hand specimen is covered with almost complete black fusion crust. Additionally, this meteorite has weak magnetic properties (i.e., a magnet is weakly attracted to the meteorite) and dense structure. Petrography (B. Miao, Chuantong Zhang, GUT): The structure is dense and there are abundant small Fe metal grains. Minerals are slightly broken, but the structure is igneous and not brecciated. Many minerals such as Low-Ca pyroxene, high-Ca pyroxene, plagioclase, SiO 2 , metal-Fe, chromite, ilmenite, troilite, zircon, rutile and baddeleyite were observed in this meteorite.

Classification: Ordinary chondrite (LL6-anomalous). The anomalous designation is based on the Fa content of olivine, magnetic susceptibility, and the opaque mineralogy. The Fa content of olivine is higher than for typical LL chondrite: only 1 out of 1715 LL chondrite has a higher Fa content (NWA 11776, LL6-an, with Fa 35.7 ). Magnetic susceptibility is also lower than in other moderaltely weathered LL chondrites. The opaque mineralogy, featuring magnetite and pyrrhotite, is unusual for a LL chondrite.

It contains dark-gray to green angular clasts of varying size (0.1 mm to 4 mm in size) within a gray fine-grained matrix. Petrography: (L. Jenkins UWO) This meteorite is a polymict breccia containing clasts of various lithologies and up to 4 mm in size (making up together about 20 vol% of the meteorite). Fine-grained to medium-grained clasts contain principally clinopyroxene, plagioclase, and silica (40% of clasts), others include orthopyroxene and olivine, with granoblastic or ophitic textures (60% of clasts). Matrix contains orthopyroxene, clinopyroxene with exsolution lamellae, plagioclase, and opaques (chromite, ilmenite, sulfides, and metal Physical characteristics: Two stones, dark fusion crust, moderately weathered exterior. A saw cut reveals some small metal grains set in a dark-brown, fine-grained groundmass, some oxide staining; one dark clast appears in the middle of the larger stone. Petrography: This meteorite exhibits a granoblastic texture with abundant triple junctions. Grain sizes are 100-300 μm in diameter. Olivine, pyroxene and plagioclase are uniformly distributed, but metal and sulfide are heterogeneous in distribution. Small (~10-20 μm) metal blebs are present, as is typical in acapulcoites. Weathering is moderate(B/C) with extensive staining of the thin section. Geochemistry: Microprobe analyses of olivines show Fa 9.14±0.14 (n=11) consistent with acapulcoite. Classification: Achondrite, acapulcoite Specimens: Three small pieces (of one stone) totaling 6.94 g and a thin section (one inch round) are on deposit at SI. Doug Ross holds the main mass of 20.98 g. The meteorite is very metal-rich consisting of ~70 vol% Fe,Ni, ~25-30 vol% silicates, <5 vol% troilite and is completely free of matrix. Minor quantities of Feoxides, probably of terrestrial origin, are present. The silicate portion is dominated by abundant, well-rounded chondrules up to 1.2 mm, mostly POP, PO and PP types. Many chondrules are fragmented. Metal phases are predominantly kamacite; taenite and tetrataenite are rarer. Accessory troilite occurs as coarse isolated grains, occasionally associated with tetrataenite. Merrillite, chlorapatite and chromite are found inside metal grains and in peripheral parts of some chondrules.

Isolated low-Ca pyroxene grains enclosed by metal and low-Ca pyroxene phenocrysts in some chondrules are replaced to various ° by Ferich olivine (Fa 27.3±0.6 ; FeO/MnO=53.8±4.1; N=13). This data was acquired by EPMA. Oxygen isotopes: (A. Pack, UGött) δ 17 O=3.69‰, δ 18 O=5.14‰, Δ 17 O=+0.96‰. Classification: Chondrite (ungrouped). Based on the chemical composition of the silicate fraction as well as the common presence of chromite and phosphates in combination with oxygen isotopes the sample shows affinity to ordinary chondrites. The olivine Fa content is not homogenized throughout the sample and the standard deviation is within the range of type 3 ordinary chondrites. The high metal content, however, is inconsistent with ordinary chondrite. Based on its petrographic and geochemical properties and oxygen isotope data, this meteorite is probably paired with NWA 12273.

Physical characteristics: Physical Characteristics: Brownish and yellow-brown weathering patina occurs on rough exterior surfaces. Fractures filled with a yellowwhite precipitate are visible cutting across the hand specimen. Interior is brown with crisply defined chondrules, and contains discreet light and dark colored clasts. Petrography: (M. Hutson and A. Ruzicka, Cascadia) The host meteorite consists of sharply defined chondrules, chondrule fragments, and light-colored clasts up to 3 mm across set in a matrix comprised of angular fragments. Chondrules range in size from 0.14 to 2.5 mm, with a mean diameter of 0.74 mm (N=129). A single large (1 cm × 1 cm) dark clast that has a sharp contact with the host consists of well-defined chondrules (diameter 0.3-2.1 mm range, 0.83 mm mean, N=48) in an opaque matrix consisting of fine-grained material of differing texture and composition than the meteorite host. Two coarse-grained light colored clasts were examined in detail. One clast (approximately 2 × 3 mm in thin section) consists of a single large normallyzoned olivine grain approximately 2.5 mm long surrounded by smaller low-Ca pyroxene grains with high-Ca pyroxene overgrowths set in a feldspathic mesostasis. The other light-colored clast (approximately 1.3 × 1.5 mm in thin section) consists of coarse (up to 0.5 mm) twinned laths of low-Ca pyroxene poikilitically enclosing a few small olivine grains. In the meteorite roughly 80-90% of the opaque minerals have been replaced by Fe-hydroxides. A large vein of calcite cross-cuts the meteorite host but does not penetrate the dark clast. Physical characteristics: Two dense stones (total 244 g) coated by a thin, dark brown patina, but exhibiting a very fresh, gray interior with some visible basaltic clasts. Petrography: (P. Carpenter, WUSL and A. Irving, UWS) The specimen is a breccia consisting of rounded mare basalt clasts with intersertal texture set in a matrix of related crystalline debris. Major mineral phases are olivine, pigeonite (some zoned to ferropigeonite) and anorthite with accessory ilmenite, merrillite, fluorapatite, troilite, zirconolite, tranquillityite and FeNi metal.

Physical characteristics:

The type specimen slice is medium to dark brown on cut faces. Well-defined chondrules and metal and sulfide are visible in lighter colored clumps, which are surrounded by darker brown areas lacking metal and sulfide, in which chondrules are not as visible. Larger light colored clasts are visible. Petrography: (M. Hutson, A. Ruzicka, Cascadia) In thin section (CML1001-2), abundant chondrules, many with sulfide-rich rims, five agglomeratic olivine objects (AO objects), and four large clasts with distinctive textures are visible. Average chondrule size is 0.71 mm (N=73), excluding the four large clasts. Two of the clasts, object 2 (5.7x4.3 mm), and object 11 (2.3x2.2 mm--truncated at edge of thin section), are composed predominantly of zoned aligned olivine crystals and bars set in a matrix of feldspathic material and pigeonite, and rimmed by layer of aluminous low-Ca pyroxene. Object 3 (2.2 × 2.1 mm--truncated by the edge of the section) consists of deformed olivine bars with almost no mesostasis. BSE imaging and mineral analyses show that this clast is equilibrated. The largest (10.8 × 7.6 mm) clast in the section (object 17) has a texture resembling that of shock melt, with equant, zoned olivine and pyroxene grains set in a feldspathic matrix. Object 17 is rimmed by an FeO-rich fine-grained material resembling matrix described by Huss et al. (1981). An oval patch (1.4 × 1.1 mm) of this same material occurs inside the clast as well and contains small multimineralic clasts, including one (20 μm across) composed of kamacite, taenite, and merrillite, and two others (10 and 15 μm across) with cores that contain aluminous spinel, surrounded by layers of fassaitic pyroxene.

Classification: Carbonaceous chondrite (CR7). This specimen exhibits a completely recrystallized texture with no evidence of remnant chondrules, and has oxygen isotopic compositions which plot on the established trend for CR chondrites. Petrography: Chondrite with well-defined chondrules set in an abundant finegrained matrix (55 vol% from point counting, n=609). Average apparent chondrule diameter 650±310 μm (n=40). Strong weathering. Opaque minerals are FeNi metal, magneite, troilite, often forming composite opaque grains. The chondrules are layered with metal/sulfide rims; opaques are also found blebs up to 300 µm in size, and some metal blebs occur at the surfaces of chondrules. XRD does not show evidence for the presence of phyllosicates. Based on the structural order of the polyaromatic matter assessed by Raman spectroscopy (L. Bonal, IPAG), this meteorite appears slightly metamorphosed, less than Bishunpur (type 3.1). The Raman spectroscopy parameters of interest are FWHM-D (cm -1 )=180.3±8.7, ID/IG=0.96±0.04, N=7 (see [START_REF] References | Thermal history of type 3 chondrites from the Antarctic meteorite collection determined by Raman spectroscopy of their polyaromatic carbonaceous matter[END_REF], figure 6).

Magnetic susceptibility log χ (× 10 -9 m 3 /kg) = 4.64. Classification: Ordinary chondrite (L3.1). Based on lack of equilibration of mafic silicates, chondrule sizes and magnetic susceptibility this specimen is an L3 chondrite, and the distribution of Cr in ferroan olivines is consistent with an L3.1 chondrite (similar to Adrar 003, as documented by [START_REF] Grossman | The onset of metamorphism in ordinary and carbonaceous chondrites[END_REF]. Specimens: 20.2 g including one polished thin section at UWB; remainder with Mr. B. Hoefnagels. Physical characteristics: The two stones, 1071 g and 57 g, are both covered in fusion crust. The larger stone has smooth, wind-polished fusion crust on about 10% of its surface. The rest of the stone appears to have been buried in the sand and not wind-polished, but has instead extremely fresh and shiny black fusion crust. Flow lines and roll-over edges are present in this fusion crust. The smaller stone may have been completely buried in the sand as it has only very fresh-appearing fusion crust and one small chipped area which exposes the interior. Broken surfaces on both stones reveal shiny maskelynite patches that are visible with the naked eye. A piece of the fusion crust was imaged using BSE, showing it to be highly vesicular with average thickness ~450 μm. Petrography: (C. Agee, UNM) The two major phases in this meteorite are clinopyroxene and maskelynite. Ubiquitous minor phases are merrillite, apatite, titanomagnetite, ilmenite, and troilite. The clinopyroxene has a modal abundance of approximately 60%, with significant core to rim zoning observed in backscatter electron images, indicating an igneous crystallization trend with Mg-rich pigeonite cores, mantled by augite, and rimmed with ferropigeonite. (April, 2018). The dealer brought the sample in Marrakech, Morocco. The stone was a broken fragment surrounded by fusion crust. A polished thin section was carefully prepared from the fragment and subsequently examined using optical microscopy to identify the texture and mineralogy and electron microprobe for the mineral chemistry. Physical characteristics: One piece. The color of the meteorite is pale brown. Petrography (I. Baziotis, AUA): Textural observations of the thin section in both transmitted and reflected light showed that it is chondritic. It contains porphyritic and nonporphyritic chondrules, both Type I (Mg/(Mg+Fe)<90). The porphyritic olivine (PO) chondrules have rounded to oval shape ranging from 300 to 500 µm. The PMD for olivine is <5% (0.25). The PMD for low-Ca pyroxene is <1%. Both monoclinic and orthorhombic pyroxene are present. The groundmass consists of olivine, low Ca-pyroxene (orthopyroxene and pigeonite), high-Ca pyroxene, plagioclase and rare phosphates (merrillite). The olivine and plagioclase show sharp extinction, indicating shock stage S1. Shock veins were not observed. The rock matrix is cross-cut by numerous interconnected opaque veins. Black fusion crust covers the sample. Red-brown oxidation is visible on the exterior surface, around metal grains on cut surfaces and within the matrix. Geochemistry: Feldspathic chondrule mesostasis Ab oxygen isotopic composition (J. Gattacceca, C.

Magnetic properties (J. Gattacceca, CEREGE) : magnetic susceptiblity log χ (× 10 -9 m 3 /kg) = 4.67 is close to the values for Bells and Essebi, C2-ungrouped, at 4.82 and 4.85, respectively. Saturation magnetization indicates 6.8 wt % of magnetite. Classification: CM2-anomalous. Though this meteorite has chondrule and matrix abundances like CMs, its alteration minerals are different: serpentine, abundant chlorite and abundant magnetite, not serpentine, cronstedtite and tochilinite, and it is possible that it is an ungrouped carbonaceous chondrite. Chlorite is found in CR alteration, but is very minor in CMs. The meteorite lacks TCI intergrowths, yet has fresh olivine. The magnetite content of 6.8 wt. % (derived from saturation magnetization Ms=6.26 Am 2 /kg) is 6 times higher than the average for CM chondrites that have Ms=1.14±0.56 Am 2 /kg.

Catalogued at ROM as LM57457 Physical characteristics: Physical Characteristics: Specimen is a 143.7 g lightbrown, sub-spherical stone with a thin, glassy fusion crust. On the exposed cut surface, multiple oxidized fractures visibly cross-cut the varying proportions of chondritic material. Few of the larger, mm-sized chondrules have oxidation rims. Petrography: Specimen contains varying proportions of mm-sized chondrules with igneous rims (avg: 0.95±0.33 mm, n=70), calcium-and aluminum-rich inclusions (CAIs) and sub-mm mineral fragments set in an opaque and crystalline matrix. Chondrules are primarily magnesian, porphyritic, and contain forsterite and low-Ca pyroxene phenocrysts surrounded by feldspathic glass and relatively low amounts of Fe-Ni metal. Modal percentage of components is ~30% for chondrules, ~20% for CAIs, 4.5% for Fe-oxides and remaining is feldspathic glass. Specimen is weakly shocked (S3), determined by presence of intersecting sets of irregular fractures in olivine crystals, undulatory extinction in olivines and pyroxenes, and melt pockets. Minor oxide rims present around metal in chondrules, and small, irregular oxide veins occur throughout the chondritic components, indicative of minor weathering. Geochemistry: Forsterite in chondrules has a mean composition of Fa 3.8±3.8 , n=53. Specimen exhibits chemistry from generally Mg-rich cores progressing to more Ferich rims. Individual forsterite grains also exhibit chemical heterogeneity, characterized by Mg-rich forsterite cores with progressive Fe enrichment near grain boundaries. Pyroxene in chondrules has a composition of Fs 3.4±18.5 Wo 15.8±5.7 , n=73. Pyroxene in chondrules and individual phenocrysts exhibit chemical heterogeneity from relatively Mg-rich cores progressing to Fe enrichment at the boundaries. Metal droplets have taenite Ni content 47.5±2.7). Secondary grains are composed primarily of olivine and pyroxene, and trace amounts of plagioclase. Oxygen isotopes (K. Ziegler, UNM): acid-treated powders gave an average of δ 17 O=-2.240 ‰; δ 18 O=2.697 ‰; Δ 17 O=-3.664 ‰ (N=3). Classification: Carbonaceous chondrite (CV3). O isotopes plot on a single trend near the CCAM trend line and fall within the CV group. Petrologic type 3 determined by chemical heterogeneity exhibited in olivine and pyroxene-group minerals in chondrules, which have greater than 5% mean deviations, expected for a highly unequilibrated chondrite. Additional characteristics indicative of a type 3 chondrite includes high proportions of monoclinic low-Ca pyroxene phenocrysts in the chondrules, absence of optically resolvable feldspar grains, and taenite Ni content. Chondrules are sharply defined, and the matrix is opaque. Specimens: The ROM holds the main mass of the sample which weighs 143.17 g. The remaining specimen is composed of two fragments, thin section and a thin section billet. Petrography: (T. S. Hayden, M. Anand, OU) The meteorite is a clast-rich fragmental breccia containing numerous mineral and lithic fragments embedded in a fine-grained vesiculated (regolith) matrix. The lithic clast population consists primarily of basaltic clasts, dominated by Ca-rich pyroxene and plagioclase, with minor olivine components. The size range of the lithic clasts is 0.19-1.9 mm. Mineral clasts are mainly pyroxene, olivine, plagioclase, chromite, troilite and Fe-Ni phases. Some impact melt textures present also. Geochemistry: Mineral Composition and Geochemistry: (T. S.

Physical characteristics:

A slice with a thickness of 2 mm was availabe. The interior of the sample appears fresh, the surface partly wind ablated and shiny -in part the minerals and clast are visible on the surface. No unequivocal fusion crust, on one side a fine layer of attached desert sand. Petrography: Macroscopic: The cut surface of the interior appears black and dark gray, with well visible white clasts of plagioclase. Mafic minerals appear grey and black and are not easily discerned from the dark matrix. Many very fine white veines transect the sample. Microscopic. Complex and polyphase breccia with different generations of impact melts and fine grained matrices. More than 50% of the thin On the EMPA different degree of devitrification and extremely fine (re?)crystallisation are visible in such glasses. The largest rock-or mineral-clasts are approx. 3 mm, the smallest grains <1 μm. Larger glass shards with included rock and mineral fragments up to 1 cm account for about 50% of the bulk, but glass is also frequent in the rest of the sample. A weak planar arrangement is visible, interpreted as a irregular layering due to fall out of impact material. Glass beads and agglutinates are present, indicative for lunar regolith. The main fraction of the sample stems from a feldspathic moon area (ANT-Suite, gabbro clast) but also basalt clasts (even mare type) are observed as minor components. A fraction of the plagioclase grains and clasts are completely transformed to maskelynite. Other grains show complex fracturing, fine grained recrystallisation and irregular extinction. Pyroxene frequently show undulous or patchy extinction. Aditional observed phases are illmenite, chrome-spinel and Fe-Ni metal. ). Melt compositions vary strongly with xSi 29.7-46.5, xCa 9.9-17.6, xFe 3.8-16.3, xMg 7.5-21.1 and xTi 0.0-3.2. Fe/Mn ratios of silicate minerals are within the range of observed compositions for the moon but on the lower end of the range with single ratios as low as 33. Bulk analysis of cut surface by pXRF (wt%): Fe/Mg = 1.5±0.1, Fe/Mn 84.2±8.8 (n=10), Fe = 4.6 wt.% (n=10). Classification: This meteorite is a mixed but mainly feldspathic glass-rich lunar regolith breccia, rich in glass and fragments with impact melts. Mineral compositions as well as Fe/Mg and Fe/Mn ratios of minerals and bulk Fe/Mn are proof for a lunar origin of the sample. Specimens: A total of 21.7 g and one polished section at NMBE Northwest Africa 12605 (NWA 12605) (Northwest Africa) Purchased: 2017 Jun 18 Classification: HED achondrite (Eucrite) History: Purchased 18 Jun 2017 at Ensisheim Show from a seller named Mr. Ismaily. Physical characteristics: A slice with a thickness of 3 mm was availabe. Surface as well as interior are well preserved and appear fresh. Fusion crust mostly preserved, flowlines visible. Porous interior. Some pores are filled around the surface with secondary minerals. Petrography: Macroscopic: The cut surface of the interior appears gray-brown, a somewhat darker and irregular rim of 1-5 mm is visible along the surface. Mineral and lithic clasts up to 9 mm are well visible. The sample is noticeably porous. The largest lithic clast is comparably coarse grained (plag. up to 2 mm) and could be a part of a cumulate (no analysis available). A narrow whitish vein transects the slice. Microscopic: The thin section consists of larger lithic and mineral clasts within a fine grained matrix that appears reequilibrated. The brecciated nature of the sample is revealed by the presence of lithic clasts with contrasting fabrics. The matrix minerals appear to have coalesced into larger grains, thereby hiding their primary clastic origin. The porosity is also observable on the microscopic scale. Locally a very fine grained rim of minerals covers the pore sufaces. Observed minerals are Ca-poor pyroxene of ferrosilitic to pigeonitic composition (with fine exsolution lamellae mainly below 10um) and Ca-rich pyroxene of augitic composition (larger grains in part poikilitic). A silica phase is common and locally shows evidence of subgrain formation. Some lager plagioclase grains show a slight patchy and undulous extinction. Several larger pyroxene grains contain irregular fractures that end at the borders of the grains. Larger, coarser grained lithic clasts have a gabbroic texture and could be derived from cumulates. Additionally observed phases are troilite, Ti-rich chromite, ilmenite, zircon and iron metal. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Small, well-formed chondrules (apparent diameter 230±120 µm, N = 22), minerals fragments, AOA and very fine grained CAI are set in a fine grained matrix (~30 vol.%, orange-brown in thin section).

Northwest Africa 12646 (NWA 12646) (Northwest Africa) Purchased: 2019 Jan Classification: LL4-7 melt breccia History: Purchased by Bob Falls in January 2019 from a Moroccan dealer. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) The specimen is a breccia composed of clasts of relatively unshocked material (which is itself a breccia) within a much darker melt matrix. The unshocked breccia clasts contain a variety of equilibrated components with a range of textures from type 4 (with well-formed chondrules) to type 7 (recrystallized with no remnant chondrules). The melt matrix is very fine grained and contains numerous small grains of metal and sulfide. Geochemistry: Type 4 clast: Olivine (Fa 30.6 ), low-Ca pyroxene (Fs 25.0 Wo 2.4 ), augite (Fs 9.0 Wo 44.4 ). Type 7 clast: Olivine (Fa 30.6-30.9 , N =3), orthopyroxene (Fs 24.7-24.9 Wo 3.2- 3.9 , N = 3), augite (Fs 10.7 Wo 43.2 ), plagioclase (An 7.7-14.0 Or 2.5-5.1 , N = 2). Melt matrix: Olivine (Fa 30.8-31.2 , N = 2), orthopyroxene (Fs 25.2-25.5 Wo 1.9-1.4 , N = 2). Classification: Ordinary chondrite (LL4-7 melt breccia). Specimens: 103.6 g including one polished thin section at UWB; remainder with Mr. R. Falls. Geochemistry: Olivine (Fa 17.9±0.1 (range Fa 17.8-17.9 ), N = 3), low-Ca pyroxene (Fs 15.6±0.1 Wo 0.9±0.1 (range Fs 15.5-15.7 Wo 0.8-0.9 ), N = 3). Classification: Ordinary chondrite (H4). Specimens: 21. The chondrite consists of about 25 vol% chondrules, chondrule fragments, and CAIs, and about 75 vol% of fine-grained material (matrix, fine grained rims; PCPs) . Mean chondrule apparent diameter is about 300 µm, typical for CM. The chondrules also have typical fine-grained rims. Geochemistry: Mineral composition and geochemistry: S. Ebert, A. Bischoff (IfP): Olivine Fa 6.36±11.4 (n=30). Most chondrule olivines have Fa<4, maximum Fa 38. Similarly, most low-Ca pyroxenes are enstatites (Fs<2), but extend up to Fs 6. Classification: S. Ebert, A. Bischoff (IfP): The textural observations suggest a CM classification of this rock. The olivines do not show undulatory extinction (shock stage S1). Low abundances of metals are still visible in chondrules, preferentially enclosed in olivines, and also as rare and very small grains in the matrix. The sample is moderately to strongly weathered. Specimens: 6.4 g including one polished thin section at the IfP and 20 g at the MNHNP. The main mass is held by Labenne.

Petrography:

The meteorite is a chondritic breccia consisting of clastic LL3 type groundmass and chondrules with embedded up to 7 mm sized LL6 clasts. Plagioclase grain size in type 6 clasts is about 60 µm. Chondrules have a mean diameter of about 0.8 mm. Geochemistry: type 3 lithology: olivine: Fa 13.1±10.9 (Fa 1.0-29.9 , n =18); pyroxene: Fs 12.7±7.9 Wo 0.8±0.4 (Fs 3.9-23.9 Wo 0.3-1.7 , n = 21); type 6 lithology: olivine: Fa 29.7±0.

Petrography:

The meteorite is a breccia with few basaltic clasts set into a coarsegrained clastic matrix predominantly composed of exsolved pyroxene and calcic plagioclase with average grain sizes of about 400 µm. Minor phases include silica, chromite, FeS, ilmenite, and barite; no metallic Fe has been found. The meteorite contains some shock melt veins. Geochemistry: low-Ca pyroxene: Fs 60.7±0.7 Wo 2.4±0.5 (Fs 58.9-61.8 Wo 2.1-3.9 , n=17, FeO/MnO=29-32); Ca-pyroxene: Fs 26.8±1.4 Wo 43.2±1.5

Physical characteristics:

The exterior of the meteorite surrounds an 8 mm thick slice received by Cascadia. This ribbon of exterior consists of a weathered surface ranging from almost black to dark brown with patches of reddish oxide and pink/tan caliche. Cut faces show medium to dark gray, angular clasts, up to 2.3 × 1.8 cm in area, set in a dark gray to black matrix. Most clasts lack clearly defined chondrules in hand specimen. A small clast, which was not sectioned contains numerous readily distinguished chondrules. Petrography: (M. Hutson, A. Ruzicka, Cascadia) A single blackened clast (approximately 2 × 0.6 cm area) fills most of the thin section, and a small triangular portion of another blackened clast (0.2 × 0.5cm; base × height) is visible in one corner of the section, with a melt-rich region along one edge of the section and between the clasts. Chondrules in both clasts are readily delineated. Silicates in both clasts are crosscut by small sulfide veins. Metal and sulfide grains appear fluidized with edges defined by the shapes of the surrounding silicate grains, and with some metal grains containing angular fragments of silicate grains. The melt region between clasts consists of weakly zoned olivine and pyroxene grains between about 20-40 μm across set in a much finer grained (< 5 μm across) matrix composed of grains of metal/sulfide, sulfide, and zoned pyroxene. This melt region contains larger metaltroilite grains, in which the troilite contains smaller blebs of metal. Coarser veins of mixed metal and sulfide cut across the melt regions. Areas containing networks of feldspathic glass are present. Geochemistry: Mineral compositions and geochemistry: Olivine and pyroxene grains in the two clasts are essentially identical, and can be considered together: Fa 24.7±0.3 , N=24; Fs 21.4±0.5 Wo 1.4±0.5 , N=22. Single zoned olivine and pyroxene grains in the melt region have slightly lower iron contents than those in the clasts: Fa 21.2± 2.2 , N=15; Fs 20.1±1.4 , N=9. Classification: Ordinary chondrite (L5-melt breccia) based on chemistry and texture. The two clasts are L5 chondrite fragments based on chemistry and texture. The presence in hand specimen of a small clast with more readily defined chondrules suggests that there may be clasts of a different petrographic type in the meteorite. The extensive melt matrix surrounding the clasts indicates this is a melt breccia. Specimens: Cascadia holds 45.5 g in three pieces, in addition to a polished thin section and a mounted butt. The main mass is held by Colvin: Christopher Colvin, 20036 Fern Glen Ln. N., Forest Lake MN 55025). Physical characteristics: Light-brown lithic clasts 0.5 to 1.5 cm across protrude through partly preserved, dark-brown fusion crust. Cut surface shows rounded lithic clasts, some of which contain feldspar laths up to ~1 mm long, surrounded by fine grained, dark-brown to black matrix. Petrography: (L. Vonopartis and L. Ashwal, Wits) A monomict eucrite breccia with angular to rounded lithic clasts up to 15 mm across, in a glassy matrix that contains mineral fragments and broken lithic clasts 0.1 to 5 mm across. Most of the lithic clasts are composed of subequal proportions of coarse-grained, subhedral plagioclase laths up to 1.2 mm long, surrounded by irregular sub-ophitic grains of low-Ca pyroxene, many of which contain augite exsolution lamellae of variable thickness. The overall texture of these lithic clasts resembles terrestrial dolerites or coarsegrained basalts, but differs from the coarse, equigranular textures typical of unbrecciated cumulate eucrites. A small proportion of lithic clasts consist of finegrained (0.01 to 0.05 mm) granoblastic aggregates of plagioclase and pyroxene, with angular mineral fragments up to 0.5 mm across. The matrix consists of dark brown, partly devitrified glass with some evidence for flow textures, which is charged with highly comminuted lithic and mineral fragments 0.01 to 0.5 mm across, very likely representing fragmental material derived from the larger lithic clasts. Both feldspars and pyroxenes in all components of the specimen show variable shock features, including kinked and offset twins, undulatory extinction and mosaicism; some plagioclases have been completely maskelynitized. Accessory minerals include chromite, ilmenite and a silica phase. Classification: (L. Vonopartis and L. Ashwal, Wits) Achondrite (eucrite). High degree of shock (S5), and low degree of weathering. Specimens: Main mass 490 g held in private collection of Dr. R. McKenzie. Type specimen 86 g, and 3 chips (8, 10, 18 g) remaining after thin section preparation Wits. A 150 mg subsample from an 18 g chip was powdered and consumed for oxygen isotopic analyses at OU.

Specimens: 8.5 g including a probe mount on deposit at UNM, Dustin Dickens holds the main mass. No remnant fusion crust is visible on the exterior. Most of the exterior is covered by a dark brown weathering rind; one surface has a lighter rusty brown matte surface. A few dark ridges stick up from the background, and one waxy grain of feldspar (5 mm × 7 mm) is visible on the weathered surface. Most of the cut faces appear dark gray, fine-grained, and featureless in hand specimen, with the exception of a thin (1-5 mm) rim of coarser-grained material (white and brown grains) near the surface. Petrography: (M. Hutson, A. Ruzicka, Cascadia): In thin section, sample is a breccia with clast textures ranging from hypidiomorphic to subophitic. Most clasts are fine-grained, with a coarse-grained clast visible on the edge of the section. Clasts are separated by a dark fine-grained matrix. Both pyroxene and plagioclase grains appear partially recrystallized in cross-polarized light, with patches of remnant twinning in many pyroxene grains and only a few of the largest feldspar grains. Feldspar is crystalline. The sample is moderately weathered with small calcite veins cutting across the section. In BSE imaging, feldspar grains contain numerous inclusions, which are concentrated on the outer margins of the larger grains. Pyroxene grains are heavily fractured. Remnant areas of twinned augite and low-Ca pyroxene, are offset by microfaults, and grade into mottled regions defined by a subtle core-rim structure. In some areas pigeonite rims surround low-Ca pyroxene cores, in other areas rims of low-Ca pyroxene surround pigeonite cores. The mottled regions are roughly 5-25 microns across, the same size as the fine-scale recrystallization seen in optical microscopy. Areas between clasts contain melt veins that cut across silicates. Phases present include pyroxene, feldspar, chromite, ilmenite, and silica polymorph Geochemistry: Mineral compositions and geochemistry: (M. Hutson, A. Ruzicka, Cascadia; K. Ziegler, UNM).

Specimens: Cascadia holds the main mass in one large piece (463.2 g) and several fragments, with a total mass of 471.9 g, in addition to a polished thin section and a mounted butt.

Northwest Africa 12938 (NWA 12938) (Northwest Africa) Purchased: 12 Mar 2019 Classification: HED achondrite (Eucrite) History: Dr. Richard Palin of the Colorado School of Mines purchased a single stone in March 2019 from a dealer on ebay (identified as matt992011). On the ebay listing, the seller says that he purchased a NWA, unclassified, probable HED from a Moroccan dealer, three years before the 2019 listing. Dr. Palin sent images of the hand specimen, a type specimen, and preliminary EMP data to Cascadia asking for confirmation that the sample was an HED, and for aid in classification. Physical characteristics: Cascadia received an end piece covered with a dark brown desert varnish. The cut face shows intermingled lighter and darker gray patches with small crystals visible in the lighter patches. Photographs of the entire specimen shows patches of remnant fusion crust surrounding uncoated euhedral to subhedral feldspar grains of varying size and abundance. Petrography: (M. Hutson, A. Ruzicka, Cascadia; R. Palin, CSM): The thin section shows two lithologies, with a sharp (breccia) contact between. One is coarser-grained with a cumulate texture, and the other finer-grained with a subophitic to intergranular texture. Phases present include pyroxene, feldspar, chromite, ilmenite, zircon, a calcium phosphate, and silica polymorph, and terrestrial calcite fills fractures. The cumulate clast contains inclusion-filled feldspars up to 1 mm in length. Feldspar grains in the finer-grained clast are always less than 400 microns long, with most less than 200 microns in length. In both clasts, in cross-polarized light, many of the smaller feldspar grains are isotropic; the larger grains contain remnant twins, with patches that are isotropic. Pyroxene grains are heavily fractured and stained brown, with darker staining near the edge of the sample. In BSE, pyroxene grains show remnant twinning grading into untwinned regions. Twins are often offset by one to several microfaults. A small melt region occurs at the contact between the two clasts and is rich in a silica polymorph. A vein dominated by silica polymorph originates in this melt region and cuts across the finer-grained clast; small areas of whole-rock melt occur along this vein. Geochemistry: Mineral compositions and geochemistry: (M. Hutson, A. Ruzicka, Cascadia; K. Ziegler, UNM). Despite textural variation, the low-Ca pyroxene (Fs 60.3±0.8 Wo 2.3±0.4 , N=27), augite (Fs 25.7±0.5 Wo 43.7±0.3 , N=13 ) and feldspar (An 84.9±1. Or<1, N=49) grains are equilibrated. Chromite Cr# = 84.1±1.7 (N=5). Oxygen data (mean and standard deviation, all in per mil and linearized): δ 17 O=1.745±0.128, δ 18 O=3.795±0.209, and Δ 17 O=-0.259±0.019 (N=3). Classification: Achondrite (eucrite) based on chemistry, texture, and oxygen isotope composition. The sample is brecciated, but the minerals have the same chemical composition, so this appears to be a genomict breccia. Specimens: Cascadia holds 14.4 g in two pieces, in addition to a polished thin section and a mounted butt. Dr. Richard Palin of the Colorado School of Mines holds the main mass.

Low-Ca pyroxene (average: Fs 17.9±2.2 ; (n = 9)) shows some variation in composition (range: Fs 13.9-19.7 ) typical for type 4 ordinary chondrites. The analysis of the oxygen isotopes (A. Pack, UGött) indicates an L chondrite heritage (δ 18 O=5.32‰, δ 17 O=3.51‰; Δ 17 O=0.74‰). The composition has been affected by terrestrial alteration. Cosmogenic radionuclide concentrations have been analyzed (M. Laubenstein, LNGS) by means of nondestructive high purity germanium (HPGe) gamma spectroscopy in spring 2019. Of the medium and long-lived cosmogenic radionuclides only 22 Na and 26 Al were positively identified. From the data, it was calculated that the meteorite probably fell about 12 (±2) years ago. Classification: Ordinary chondrite (L4, S3, W1) Specimens: 20.5 g and polished thin section The meteorite was purchased from a meteorite dealer in Zagora, Morocco. Physical characteristics: Dark greyish rock partly covered with fusion crust. Petrography: The meteorite displays a dark greyish interior and is composed of up to 6 mm sized angular type 4 clasts set into type 3 matrix. Olivine and low-Ca pyroxene are compositionally unequilibrated in the matrix; equilibrated Fe-rich olivine is the most dominant mineral phase in the clasts. Low-Ca pyroxene is also compositionally unequilibrated in the matrix. More minor phases include Capyroxene, sodic plagioclase, sulfides, and Ti-bearing chromite; no metal has been detected. Geochemistry: type 3 lithology: olivine: Fa 28.0±13.7 (Fa 5.3-39.2 , n= 17); pyroxene: Fs 14.4±6.5 Wo 1.6±0.9 Wo 0.4-3.3 , n=10); type 4 lithology: olivine: Fa 38.9±0.2 , n=1; pyroxene: Fs 24.3±4.1 Wo 0.9±0.5 Wo 0.4-1.9 , n=17)

Minas Gerais, Brazil Find: before 1968 Classification: Iron meteorite (IAB-sLL) History: The meteorite was given before 1968 to Djalma Guimarães (now deceased) from Industrial Technology Institute (ITI, Minas Gerais) while he was working in João Pinheiro (Minas Gerais). The meteorite was then kept by Prof. Cláudio Vieira Dutra until the inauguration of the Djalma Guimarães Museum in 2000. Physical characteristics: Semi prismatic shape. Petrography: (F. N. Puchetta, UFOP and M. E. Zucolotto MN/UFRJ) -Etched sections display a coarse widmanstätten structure with bandwidth of 1.80±0.50 mm. Neumann lines are common. Plessite occurs in minor amounts as degenerated comb, pearlitic and spheroidized plessite. Some acicular and martensitic plessite is also observed. Cohenite is very common on most sections. Troilite and schreibersite are also present. Rhabdites are very common and tetragonal prisms in some kamacite lamellae. Geochemistry: 7.9 wt% Ni; 0.47 wt% Co; 80.0 ppm Ga; 335 ppm Ge; 1.66 ppm Au (INAA, J.T. Geochemistry: (R. Bartoschewitz, Bart) Olivine Fa 18.8±0.4 (n=136); pyroxene (low-Ca) Fs 16.7±0.7 Wo 1.3±0.2 (n=82); kamacite Co 0.64 % (n=15) Magnetic susceptibility log χ (× 10 -9 m 3 /kg) = 4.86 and bulk density of 3.40 g/cm³. Terrestrial Ar-, Kr-, Xeisotope contamination (K. Nagao, R. Bartoschewitz) is much higher than known from European finds, but are consistent with the contamination trend in hot deserts. Sr (B. Hofmann, handheld XRF) of 79 ppm is not consistent with lower Saxony preglacial inland dune content, but is consistent with weathering in hot desert environment. Classification: Ordinary chondrite (H5, S2/3, W2-4) Specimens: 11.6 g on deposit at Kiel, I. Klümper holds the main mass, and 14 g with Bart.

Physical characteristics:

Half-fist sized dark red-brown sample with 95% smooth fusion crust, a small amount of lichen attached. Petrography: (L. Bowlt) Chondrules range in size up to 1.2 mm diameter, have diffuse boundaries and sit in a highly recrystallised matrix. Mineralogy includes olivine, pyroxene, plagioclase (many plagioclase grains exceed 50 μm), Fe-Ni metal and troilite. Chondrule types include BO, RP, PO, PP, POP. Metal and troilite grains are large, both ranging up to 1 mm in size. Plagioclase is abundant (20-30%) and some has been converted to maskelynite. Olivine grains show undulose extinction, mosaicism and contain distinct perpendicular sets of shock lamellae. Moderate oxidation of metal and troilite has occurred with 20-25% of the grains affected. Given that most oxidation occurs as rims on the metals/sulfides and there are no oxide veins, estimates of original percentages of metal and troilite are approximately 1-3% and 5-15% respectively. Geochemistry: (L. Bowlt, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa an EL3 of the same weathering extent; given the rarity of EL3 chondrites, they are likely to be from the same fall, thus representing a much larger strewn field. Physical characteristics: Numerous broken fragments up to 10 cm, blocky or flat, weathered to dark brown. Petrography: (A. Tait, A. Tomkins, Monash) This sample is dominated by orthopyroxene (>95%), although a small proportion of chondrules (~10%) contain olivine. Chondrules are well defined and are mainly RP and PP; they range in size up to 5 mm, with many in the range 1-4 mm. The matrix is opaque and chondrule mesostases typically extremely fine grained (crystals <1 μm). Olivine has straight extinction, and there are no indicators of higher shock. Greater than 95% of the metal has been oxidized, but remaining metal contains exsolved acicular pyroxene crystals, and these can also easily be seen in iron oxide pseudomorphs of metal. Petrographically this meteorite has the same silicate petrography, shock characteristics and extent of weathering as Watson 007, which was found 15 km to the west. Given the rarity of EL3 chondrites, it is highly likely that these are from the same fall, and represent part of a relatively large strewn field. Geochemistry: (A. Tait, Monash) Low-Ca pyroxene has Fs 0.12-1.93 , mean = Fs 0.74±1.03 , n=3, olivine has Fa 0.13-2.09 , mean = Fa 0.46±0.72 , n = 7; metal has 0.55 wt.% Si. Classification: The sparse olivine and very fine grained chondrule mesostases are consistent with Type 3 classification. Low Si in metal indicates EL. Enstatite Chondrite (EL3, S1, W4).

Ooldea 011 30°30'9.30"S, 131°51'23.50"E South Australia, Australia Find: 2015 Apr 15 Classification: Ordinary chondrite (LL6) History: One fragment found by A. Tait, embedded in a cryptogamic soil horizon. Found during the Monash University meteorite recovery expedition. Physical characteristics: One oval fragment 18 mm long, no fusion crust. Contains crosscutting calcite/gypsum weathering veins. Petrography: (A. Tait, Monash) Chondrule edges are poorly defined, marked by extensive recrystallization of the matrix. BO and POP relict chondrules are rare, with equilibrated edges. Large (>100 μm) skeletal plagioclase grains exist across most the sample, with blebs of FeNi-alloy melt. Fe-oxide weathering is extensive with <5 wt% FeNi and/or sulfides remaining. Olivine show undulose extinction, but there are no indicators of higher shock. Geochemistry: (A. Tait, Monash) EDS analyses show that olivine and pyroxene compositions are uniform: olivine Fa 25.7-28.5 , mean= Fa 26.9±1.0 (N=11). Low-Ca pyroxene Fs 20. 4-23.8 Wo 1.8-1.2 , mean Fs 21.3±1.0 Wo 1.5±0.2 (N=13). Classification: Ordinary Chondrite (LL6, S2, W4) Specimens: The main mass and a thin section are held at Monash Under the curation of A. Tomkins. Petrography: (J. Savage, Monash) This meteorite is a genomict breccia consisting of two fragments. Nonporphyritic chondrules >1 mm are identifiable in one fragment amongst fine-grained matrix of plagioclase/maskelynite, pyroxene and olivine (chondrule types: PP, POP, RP, BO, PO, C). The other breccia fragment has lost all chondrule texture, with the exception of one 1.2 mm POP chondrule with a thick troilite rim. The contact between the two fragment types is gradational. All olivine, pyroxene and plagioclase show undulose extinction; some pyroxene and olivine grains have shock lamellae, and multiple olivine grains exhibit mosaicism. Fe-Ni metal shows<10% weathering, troilite <5%. Geochemistry: (J. Savage, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa 23. mean Fa 23.8 ,std=0.5,n=4; , mean Fs 20.13 , std=0.47, n=5. Classification: Ordinary Chondrite (L5-6, S4, W1).

Oued Sfayat

26°42.433'N, 6°9.766'W Tindouf, Algeria Confirmed fall: 16 May 2019 Classification: Ordinary chondrite (H5) History: On May 16, 2019, a meteor was seen by a group of shepherds at 9:00 pm (local time) at the Dakhla camp in Tindouf, Algeria. The meteor came in at a low angle (about 30 °) from the west and was moving east at a relatively low velocity. A shockwave was felt as the meteor exploded, and a booming sound was heard near the camp. Hibballah, one of the shepherds present at the camp, went in search alone the following morning (May 17, 2019) for pieces of potential meteorites that may have fallen, by following the direction of the observed meteor trail and booming sound. That same day, Hibbballah recovered the first fragment, an 80 g freshly crusted individual in the area of Oued Sfayat, a river valley about 70 km to the east of the Dakhla camp. After finding this piece, Hibballah returned to the camp to tell his father Oueld Ennajm the location where he had found the first piece. Several days later, Oueld Ennajm and a some shepherds traveled to Oued Sfayat and over the next few of months went searching for more fragments. After searching between the end of May through the middle July in a 1-2 km area at Oued Sfayat, about 8 kg of freshly crusted individual fragments (mostly small stones of varying sizes between 10-60 g, with the exception of a few larger-sized individuals ~600 g) were recovered by Oueld Ennajm and the shepherds. Some of these recovered fragments were then later sold to Ahmed Chacha and Otman Sidi Ahmed. Later on, some of the purchased fragments (2.6 kg) were subsequently purchased by Youssef Bennani, who later sent some small stones in for analysis. Classification: Ordinary chondrite (L5) History: Found in 2009 by meteorite-hunter, John Wolfe, while visually searching the surface of the dry lake. Physical characteristics: This meteorite is a well-rounded, nearly-whole individual stone. The exterior is dark, grayish-brown and is 90% covered with a 2 mm-thick, relict fusion-crust, which is smooth and has very little in the way of rust-spots. A cut surface shows the interior is half-tan and half-orange in color, with few distinct chondrules in a compact matrix with very low metal-grain content, and few troilite grains. Petrography: (Daniel Sheikh, FSU) Chondrule boundaries blurred (700±100 µm, N=3). Recrystallized matrix with plagioclase (10-25 µm). Geochemistry: Olivine, Fa 22.6±0.9 (N=25); orthopyroxene, Fs 19.4±0.9 Wo 2.5±0.7 (N=25). Classification: Ordinary Chondrite (L5) Specimens: 2.16 grams at UCLA; main mass with Verish.

24.658°N, 14.692°W Rio de Oro, Western Sahara Find: 2015-Apr Classification: Lunar meteorite (feldspathic breccia) History: The stone was found by two Moroccan hunters in April 2015 in a barren region. Further searching in the area led to the recovery of other similar-appearing stones totaling 15.6 kilograms, but this first stone was considered to be possibly different (because of the presence of some larger lithic clasts), and it was excluded from the classification of the other stones as a group under the name NWA 10495. Subsequently the first stone was sold by the finders to a Moroccan dealer, who in turn sold it in February 2018 at the Tucson Gem and Mineral Show to representatives of ArtAncient (a British antiquities dealer). Physical characteristics: A single, dark brown stone (282 g) lacking fusion crust but exhibiting a glossy weathering patina. Sawcuts reveal a very fine grained interior with diffuse larger whitish to black clasts. Petrography: (A. Irving and S. Kuehner, UWS; P.

26.707°N, 8.936°W Moments later, Madam Gohari a resident of Taqtaq-e Rasoul village (next to a hill with a similar name) noticed an object fall in their family yard, producing dust and getting dogs excited, surrounding it. After receiving a call from his mother about the event, Saman Gohari arrived at the site after 20 '. Informed about meteorites, he collected the stone (claiming that the stone was still hot). Because of site's vicinity to Iraq's border (~4 km), police investigated the site and the rock was broken into several pieces (two main pieces). As the area close to the border is covered by land mines, searching for more fragments was not possible. Several search attempts in the farms around the house and the villages failed to find additional fragments. A ~30 g fragment, along with several small fragments (~14 g together) were sent to Hamed Pourkhorsandi for study. Physical characteristics: Originally a single stone was covered with fusion crust. A layer of soil was visible on the surface, resulting from its impact with the ground. Light-gray interior hosts chondrules. Metal and sulfide grains are visible by naked eye. Petrography: Chondrite with recrystallized texture. Plagioclase average size is 40 µm. Opaque minerals are Fe,Ni metal and troilite.

Classification: Ordinary chondrite (H5) based on petrography, magnetic susceptibility and mineral chemistry. Specimens: A piece of ~1050 g is with the finders, ~650 g is with the police, and ~260 g is in Hojat Kamali's private collection. Type specimen (30 g) and a polished section at CEREGE. 14 g at RBINS. quenched melt and igneous-textured microporphyritic melt domains. The black clasts show an even distribution of metal and sulfide, typically <500 μm across, and significant porosity as vesicles 10 to 200 μm, some with euhedral grains protruding into the voids. Rare melt pockets to 100 μm. In the two sections, the chondrules in the black clasts are largely integrated into the matrix. A few PO and BO chondrules were recognized. The silicates contain an abundance of small, <1 μm, sulfide and metal grains. Clast metal dominated by kamacite, lacks Neumann bands, is anhedral though with curved outlines. It is typically single crystal, though some show a lathlike martensitic texture. Most kamacite grains have a "frothy" coating of troilite. Troilite is single crystal to polycrystalline and lacks shock lamellae. Metal/troilite grains >2 mm in the melt show eutectic textures. Grains smaller than 2 mm consist of Fe-Ni spheres with coatings of troilite. Chromite is a common accessory as anhedral grains to 200 μm. Feldspar, as anhedral grains, have a wide size distribution from <10 to >50 μm. Geochemistry: (L.

Tocache

8°11.78'S, 76°28.64'W San Martin, Peru Confirmed fall: 1998 Jan 01 Classification: Ordinary chondrite (H5) History: The meteorite fall was witnessed by Mr. Leodegario Tolentino Laiza and Mrs. Horacia Padilla Herrera in the Tocache District, Tocache Province, San Martín Department, Peru. According to the witnesses, the fall occurred between midnight and two in the morning of January 1, 1998. A fireball was observed in the sky and, within ", it exploded. Soon after, a humming sound, like a small plane, was heard and then two impacts on the ground were felt. In the following week, Mr. Leodegario found the 5140 g fragment on his coffee plantation, in a small crater 1 m deep by 50-80 cm in diameter in the clay soil. According to him, the meteorite had a smell that resembled something burned and with sulfur. The meteorite was kept in a shed of the property, being exposed to the high humidity of the region that is part of the Peruvian Amazon. In 2017, the fragment was acquired from the couple's son, Mr. Willy Tolentino Padilla, by the Quimiosfera Laboratory at the Chemistry Institute of the University of São Paulo (USP) for study and classification. Physical characteristics: The only fragment of the fall was acquired by the laboratory and weighed 5110 g, in addition to 30 g of fragments that were previously broken and sent by the owner. Thus, the final mass added up to 5140 g. The fragment was covered in about 80% of a dark-reddish fusion crust with different ° of oxidation. The exposed inner parts also have several rust colored spots of oxidized metal flakes. The fragment measured about 22 × 13 × 13 cm before the cut. One of the sides shows slight signs of orientation and, in one of the exposed inner parts, the meteorite shows a feature positively identified as a shatter cone. The conical and striated structure has 3 × 4 cm and was partially damaged by the action of the former owner during the removal of the 30 g of fragments that were first sent to the laboratory. Petrography: Chondrule apparent diameter typically between 0.3 and 0.8 mm (mean 0.5 mm). Chondrules are not well defined. The chondrules represent around 60 to 70% of the area of the meteorite thin section. Most of the types seen are PO and POP, with RP appearing in lesser proportion, with no identified CAIs or AOAs. The Ol/Px proportion is around 80%/20%. More than 95% of the pyroxene crystals are orthopyroxenes, while 5% are clinopyroxenes. Olivine show light undulatory extinction, while virtually every pyroxene crystal shows strong undulatory properties. The pyroxene crystals commonly show both irregular and planar fractures. In contrast, the olivine crystals only show irregular fractures, while planar ones are rare. The metorite shows several long and thin melt veins (around 400 μm wide), some of them with small melt pockets and presence of melted metal and troilite flakes or even whole melt metal veins. The opaque phase makes up 11% of the meteorite volume (tomography), of which ~7-8% is kamacite/taenite, 3% is troilite and possibly 0.1 to 0.2% is chromite. The metal flakes have sizes varying between 0.1 and 1 mm (mean 0.3 mm), with some degree of connection between them being moderately common. Neumann lines can be seen on kamacite crystals and around 20 to 30% of the metal has already been oxidized. This generates an orange staining on the silicate phase around the metal flakes, being that areas near the surface show more oxidation than inner areas (F. Falco, USP). Geochemistry: Mineral compositions and geochemistry: Olivine (Fa 20.1±0.8 ; N=82), low-Ca pyroxene (Fs 16.6±0.6 Wo 1.3±0.7 ; N=60), high-Ca pyroxene (Fs 11.2 Wo 25.7 ; N=1), feldspar (Ab 78.3±4.5 An 15.7±6.4 Or 5.9±4.7 ; N=7). MEV/EDS: troilite (Fe = 64.7±0.6 wt%, S = 35.5±0.6 wt%; N=2), kamacite (Ni = 7.2±1.5 wt%; N=2), taenite (Ni = 29.8±3.7 wt%; N=2), tetrataenite (Ni = 46.2±0.6 wt%; N=1), chromite (Cr/(Cr+Al): 0.88±0.06; N=4), zoned Cr-spinel (edge = Cr/(Cr+Al): 0.58±0.05, Mg/(Mg+Fe): 0.22±0.03, Ti: 0.5±0.1 wt%; N=3) (center = Cr/(Cr+Al): 0.29±0.04, Mg/(Mg+Fe): 0.40±0.03; N=3), apatite (Cl: 5.0±0.2 wt%, F: 1.2±0.2 wt%; N=1), ilmenite and merrillite (RAMAN).

Viñales

22°37.17 A long smoke trail was also observed. The residents thought a plane had crashed, as they heard explosions and then ground rumbling lasting 15 to 20 s. A meteorite shower fell on Vinales Valley, a national monument since 1978 and a UNESCO world heritage site. The area is covered by a forest and fields. The first and some of the largest stones were collected near the monument "Mural of Prehistory" by artist Leovigildo Gonzalez Morillo. Others were discovered in and around Viñales and throughout the Viñales Valley. Some of the meteorite individuals penetrated the ground, one of them broke through an asphalt road, and many were recovered from rooftops. Physical characteristics: Hundreds of individual samples were collected by the local residents. The stones are covered by black fusion crust with reddish smears of a laterite clay. The substance of the meteorite of light gray color can be seen in small areas of the broken crust. The masses of stones are in a range 2 to 1100 g. In total, about 50-100 kg of the meteorite were collected. Petrography: The interior is light-colored; silicates are transected by dark, pseudotachylite-like shock veins. The rock is highly recrystallized; chondrule margins are difficult to discern. Recognizable chondrule types include POP, PO and BO, ranging up to ~1 mm in diameter. The meteorite samples contain the several vol% of black inclusions of melt rock. Metal grains range in size up to about 700 µm. The rock exhibits moderate silicate darkening. Chromite grains are moderately to extensively fractured. Some troilite grains and some kamacite grains are polycrystalline. A few kamacite grains contain small rounded grains of troilite within them. Metallic Cu was not observed. There are several small chromite-plagioclase assemblages and some olivine grains contain small chromite veinlets. The shock veins range to more than 1 cm in length and are typically 20 µm to 150 µm wide. The veins contain major silicate and small blebs of metallic Fe-Ni, and to a lesser extent, troilite; these opaque blebs are typically 1-3 µm in diameter. Also present in the veins are cellular metal-troilite veinlets 10-30 µm in length. Elongated aggregates of chromite occur alongside portions of some shock veins. Slabs of Viñales show intersecting dark shock veins, anastomosing veins, and a few quasi-circular melt concentrations where veins intersect. Coarse metal grains are heterogeneously distributed in some samples -some regions of these samples have abundant coarse metal; other regions have none. Near the dark fusion crust, numerous thin veinlets of troilite surround and penetrate fractures within silicate grains. Magnetic susceptibility (J.

Wadi El Gamal

Egypt Purchased: 1974 Classification: Iron meteorite (IIIAB) History: Qarabawi's Camel Charm was acquired from Abdullah Qarabawi of the Ababda tribe of eastern Egypt and donated to the Smithsonian Institution in 1974 by the Geological Society of Egypt. Although the location of the meteorite find is not known, it was found by the Ababda tribe. Wadi El Gamal, translated as the Valley of the Camel, is the name of a 7000 km2 national park, which can be found on the edge of the Red Sea, within the traditional homelands of the Ababda. A heritage center opened in this park in 2006 dedicated to preserving the heritage of the Ababda.

Physical characteristics:

The charm consists of an ~6.5 cm flattened disk (thickness 5 mm) with the Arabic inscription "Allahu Akbar", which translates as "God is Greatest." Attached to the charm are four links, also made of meteoritic material. Petrography: Non-destructive analyses of the disk and metallographic examination of the distal link reveal a deformed medium octahedral pattern, confirming the meteoritic origin of the Camel Charm. Geochemistry: Major, minor, and trace element compositions are consistent with classification as a IIIAB iron. Fe 91.75 wt %, Ni 7.76 wt %, P 0.09 wt %, Co 0.01; Ir (14.63 ppm, LA-ICP-MS), Ni (7.76 wt%, microprobe analyses), Ga ( 28

  2 stones totaling 2794 g with Joshua Earth & Space Museum. Found in 2015 by nomads on a small hill named Grarat-Zawi, and purchased by Darryl Pitt on behalf of MMGM from Mauritanian dealers in the period August-October 2015. Physical characteristics: A single, very large stone (27.249 kg) found as a group of many pieces which fit together (but with several missing pieces). The specimen lacks fusion crust, but individual pieces have thin coatings of light-brown weathering products. Fresh interiors exhibit angular, whitish clasts within a dark-gray matrix. Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed predominantly of mineral clasts plus rare glass clasts and basalt clasts in a finer grained, partly vesicular matrix. Minerals are anorthite, olivine, pigeonite, orthopyroxene, exsolved pigeonite, subcalcic augite, Al-rich chromite, ilmenite and baddeleyite. Minor amounts of secondary calcite and barite are present. Fs 49.6 Wo 28.3 , FeO/MnO = 59), plagioclase (An 95.2-97.1 Or 0.1-0.2 , N = 3). Bulk composition (R.

Classification: Lunar (feldspathic regolith breccia). Based on closely similar bulk chemical compositional data (determined by Dr. R. Korotev at WUSL utilizing the same INAA methods), it is likely that the NWA 10509 stone and the material classified as NWA 10798 are paired portions of the same disaggregated meteorite.

One stone of 15.1 g was received by Erich Haiderer in Bavaria, Germany, in late 2018 from an anonymous Moroccan dealer, who reported that the rock came from the Sahara. Petrography: (A. Bischoff, IfP) The rock is brecciated and has a chondritic texture with chondrules (mean diameter about 0.6 mm) in a fine-grained matrix that contains sulfides and FeNi metals. The metal abundance is about 4 vol% and certainly significantly below the abundance in H chondrites. Besides the chondrule size, the metal contents are consistent with an L-group classification. The sample shows only minor weathering. Geochemistry: (K. Klemm; A. Bischoff, IfP) The breccia contains fragments of different petrologic type, some unequilibrated, but most are equilibrated and type L5. The equilibrated type-5 fragments have mean olivine and pyroxene compositions of Fa 22.8 and Fs 19.4 , respectively. Random measurements of olivine grains revealed Fa 20.5±5.8 (Fa 5.2-24.4 ); n=9. Random measurements of low-Ca pyroxene grains revealed Fs 15.3±6.6 Wo 1.2±0.7 (Fs 2.4-20.0 Wo 0.3-2.4 ); n=10. Classification: Ordinary chondrite (L3-5). The classification is based on chondrule size, metal abundance, brecciated texture, and mineral chemistry. Twenty-three identical stones with a total known weight of 530 g were found in Western Sahara in 2018. The samples were purchased from a prospector in Rissani in 2018 and subsequently obtained by David DGregory during the 2019 Tucson Gem and Mineral Show. Physical characteristics: Samples are irregularly shaped, lack fusion crust and are dark gray with light-colored clasts. Vesicles are visible on surface. Some samples appear to be composed mostly of melt and contain higher density of vesicles. Petrography: Description and classification (A. Love, App): A representative 23 g individual displaying the brecciated and vesicular melt textures was selected as the type specimen for description and analysis. The sample is a breccia composed of rounded clasts of coarse-grained (1.2 mm pyroxenes and 1 mm plagioclase), basaltic textured eucrite and related mineral debris set within a vesicular, quench-textured melt matrix. Clasts contain lithic fragments with embayed, exsolved pyroxenes surrounded by vesicular plagioclase. Additional minerals are: Si polymorphs, rare baddeleyite, phosphate, zircon, Ti-poor (3 wt% TiO 2 ) and rich (<18 wt% TiO 2 ) chromite which is sometimes inter-grown with ilmenite, troilite and Fe metal.

Melt Matrix: Pigeonite Fs 64.4±6.2 Wo 18.6±3.8 , Fe/Mn=34.7, Mg#=8.7-38.2, N=6. Classification: Eucrite-melt breccia. Specimens: David DGregory holds the remaining 22 individuals that comprise the mass of this meteorite. One partially cut stone weighing 21.15 g and a polished thin section comprise the type specimen and are on deposit at App. One large uncrusted 2000g stone was found in Western Sahara in 2018. John Sinclair purchased the sample from a meteorite prospector at the Tucson Gem and Mineral Show in 2019. Physical characteristics: Sample lacks a fusion crust, is yellowish-orange in color and crystalline. Cut face shows a granoblastic texture and dark colored-opaque grains. Petrography: Description and classification (A. Love, App): Sample shows a granoblastic texture composed of 517 µm olivine, low-Ca pyroxene, twinned Cpx and twinned plagioclase that meet at 120º grain boundaries. Additional minerals are phosphates, troilite, chromite, and oxidized FeNi metal grains. Geochemistry: (A.

  This meteorite was reportedly discovered by Ingo Klümper, Brandlecht, while he was searching with metal detector in 5 cm depth beside a forest path SW of Nordhorn/Lower Saxony (52°22.696'N, 7°05.919'E) on Feb. 27, 2016. However, a find in eolian sand is neither consistent with very high accumulation of U (see below), which requires a much higher terrestrial age than the embedding sediment, nor with crack fillings of carbonates. Noble gas isotopes and radionuclides require a very large crater-forming object. Therefore this report is in doubt. Physical characteristics: (R. Bartoschewitz Bart) One iron piece of about 7.5 × 4 × 3 cm and 370 g. Petrography: (R. Bartoschewitz Bart) The meteorite shows a bulky coarse Widmannstätten pattern with bandwidth of 2-5 mm with Neumann lines and rhabdite. Graphite, troilite and schreibersite occur on kamacite boundaries. Corrosion cracks filled with Fe-hydroxides and carbonates.

Purchased: 2016 Dec Classification: HED achondrite (Eucrite, monomict) History: Purchased by Beat Booz in December 2016 from a Moroccan dealer. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed of microgabbroic eucrite clasts plus mineral clasts of related crystalline debris, both exhibiting some preferred dimensional orientation. Minerals are exsolved pigeonite (pale orange in thin section), calcic plagioclase (polycrystalline) together with accessory ilmenite, Ti-chromite, troilite and zircon. Minor secondary calcite is present. Geochemistry: Low-Ca pyroxene Wo 3.8-5.6 , FeO/MnO = 28-33, N = 3), high-Ca pyroxene Wo 43.0-42.5 , FeO/MnO = 30-34, N = 3), plagioclase (An 92.1 Or 0.2 ). Classification: Eucrite (monomict breccia, microgabbroic, shocked) Specimens: 21.9 g including one polished thin section at UWB; remainder with Mr. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Cumulate texture. Grains (mean grainsize 0.7 mm) of olivine (some exhibiting undulose extinction) and clinopyroxene (pigeonite and subcalcic augite; some as oikocrysts enclosing small olivine chadacrysts) occur with intercumulus briefringent, twinned plagioclase (~15 vol.%) and accessory Mg-bearing ilmenite, Ti-chromite, pyrrhotite and merrillite. Both olivine and pyroxenes have limited compositional zoning. Geochemistry: Olivine (Fa 34.7-36.8 , FeO/MnO = 50-52, N = 4), pigeonite (Fs 24.7- 30.4 Wo 4.8-8.6 ; Fs 28.2 Wo 16.6 ; FeO/MnO = 28-30, N = 5), subcalcic augite (Fs 20.7 Wo 24.1 ; Fs 17. ; FeO/MnO = 24-26, N = 3), plagioclase (An 56.9-58.1 Or 0.8-0.9 , N = 2). Classification: Martian (shergottite, olivine gabbroic, orthocumulate, low shock). Texture, mineralogy and degree of shock are essentially identical to those observed in NWA 12241, with which this material is almost certainly paired. Although the broken pieces of NWA 12241 were purchased in far southern Algeria (close to the border with Mali), there is no assurance that they were found in Algeria, whereas the find location for these newly-studied pieces is reliably established as Mali. Specimens: 20. Petrography: (J. Gattacceca, CEREGE) Chondrules (average apparent diameter 890±270 µm, n=15) and CAIs set in a iron-rich fine-grained matrix. Opaques are sulfides and magnetite.
