Neuschwanstein .............................47°31.5' N, 10°48.5' E Bavaria, Germany Fell 2002 April 6; 20:20 hrs (UT) Enstatite chondrite (EL6) A brilliant fireball, shaking the ground and rattling windows, was reported by many eyewitnesses in Austria and Germany on 2002 April 6, 20:20 hrs (UT). The fall circumstances were well documented by the European Fireball Network (EFN). Reduction of the EFN photographs allowed calculation of the orbit and impact area (Spurny et al., 2002) which ultimately led to the recovery of a single stone of 1.75 kg on 2002 July 14. Major phases are enstatite (FeO <0.1 wt. %), plagioclase (Ab82), and metal (~1.5 wt. % Si). Large crystals of sinoite (up to 200 m) and graphite (up to 700 x 200 m) are present. Additional phases so far observed are schreibersite ((Fe,Ni)3P), troilite (FeS), oldhamite (CaS), daubreelite (FeCr2S4), alabandite, ((Mn,Fe)S) and an SiO2-phase (containing 1-2 wt. % Al2O3). Bulk chemistry: abundances of moderately volatile lithophile elements are typical for EL chondrites, low Mn/Mg = 0.010 and Na/Mg = 0.045, and low Zn concentration (Zn <20 ppm); high concentrations of siderophile elements, e.g., Ni = 1.94 % and Ir = 0.76 ppm, reflect higher than usual metal contents for EL chondrites. Optical features indicate that the rock is very weakly shocked (S2). The residence time of about three months on the ground resulted in the first signs of weathering (W0/1). The exposure age is ~48 Ma; trapped subsolar noble gases are present (L. Franke and L. Schultz, MPI). Specimens: type specimen, 20 g, MPI; thin sections: Mün; main mass, unknown.

Northwest Africa 856 Unknown Found 2001 March Martian meteorite (basaltic shergottite) A single stone of 320 g was found in Morocco in 2001 March. The exact location of find is unknown and the meteorite was referred to under the pseudonym "Djel Ibone". The meteorite has a fine-grained basaltic texture consisting mainly of pyroxene (70 vol%) and maskelynite (23 vol%). Accessory minerals include merrillite, apatite, pyrrhotite, chromite, Fe-Ti oxides, silica (stishovite) and baddeleyite. Melt pockets with phenocrysts and submicrometer-sized needles of stishovite are present. Pyroxenes are highly fractured. Calcite veins formed by terrestrial weathering crosscut the specimens. Classifica- tion and mineralogy (A. Jambon, UPVI; V. Sautter, MNHNP; Ph. Gillet, ENSL): pyroxenes are pigeonite, En48Fs39Wo13, and augite, En36Fs32Wo32; maskelynite composition is An41.47Ab57.51Or2. Geochemistry (J-A. Barrat, UAng and Ch. Göpel,IPGP): bulk composition in wt% is 0.81 TiO2, 6.83 Al2O3, 17.8 FeO*, 0.49 MnO, 9.51 MgO, 10.2 CaO, 1.28 Na2O, 0.13 K2O.

Abundances of Ba and Sr and the Th/U ratio indicate that terrestrial weathering is minor. Specimens: type specimen, 16 g, ENSL; main mass, Fectay. Northwest Africa 869 Northwest Africa Find: 2000 or 2001 Ordinary chondrite (L4-6) History: It is quite clear that meteorite collectors in Northwest Africa have discovered a large L chondrite strewnfield at an undisclosed location. At least 2 metric tons of material comprising thousands of individuals have been sold under the name NWA 869 in the marketplaces of Morocco and around the world. Individual masses are known to range from <1 g to >20 kg. It is certain that NWA 869 is paired with other NWA meteorites, although no systematic survey has been done. It is also possible that some stones sold as NWA 869 are not part of the same fall, although dealers are confident that most of the known masses are sufficiently distinctive from other NWA meteorites in terms of surface and internal appearance that the error rate should be fairly low. Scientists are advised to confirm the classification of any specimens they obtain before publishing results under this name.
Petrography, Composition and Classification: (A. Rubin, UCLA) A fragmental breccia of type 4-6 material; one thin section dominated by an L5 lithology gave olivine = Fa24.2. Classification: Ordinary Chondrite (L4-6); S3,W1. Type specimen: A 189.3 g sample on deposit at UCLA. Northwest Africa 960 (Provisional) Morocco Find (purchased December 2001) Chondrite (Type 3, Anomalous) History: Purchased in 2001 December by Adam and Greg Hupé from a Moroccan dealer in Erfoud. Physical characteristics: A single dark brown stone weighing 997 g. Petrography: (A. Irving and S. Kuehner, UWS; M. Zolensky, JSC): Very chondrule-rich (~80 vol.%), with a brown oxidized matrix. Most chondrules (up to 3 mm in diameter, though most below 1 mm) are olivine-rich but some contain low Ca pyroxenes (Fs2-34, with a peak at Fs 2-3, average Fs10.46). Minor magnetite, troilite, pentlandite, chromite and glass. No metal was observed. Geochemistry: Olivine (Fa2-29, with a peak at Fa2-3; average Fa9.63), low Ca pyroxene (Fs2-34, with a peak at Fs 2-3, average Fs10.46). Oxygen Isotopes (R. Clayton, UChi): d18O = 7.50; d17O = 4.50; D17O = +0.54 per mil; (D. Rumble, CIW): analyses of two whole rock fragments by laser fluorination gave, respectively, d18O = 6.03, 6.04, 6.18; d17O = 3.74, 3.78, 3,83; D17O = +0.559, +0.592, +0.567 per mil. Although the D17O values are near those for H chondrites, the d18O values are much higher, and the mineralogy of this specimen is very different from that of H chondrites. Classification: Chondrite (Type 3, Anomalous), S1, W1-2. Specimens: A total of 23 g of sample and one polished thin section are on deposit at UWS. A. and G. Hupé hold the main mass. Northwest Africa 969 Morocco Purchased 2001 June/October Ordinary chondrite (LL7) A small stone was purchased from a Moroccan dealer by A. and G. Hupé (Hupé) in 2001 June, and subsequently seven more stones were purchased bringing the total weight to 463 g. Classification and mineralogy (A. Irving and S. Kuehner, UWS): Genomict breccia consisting of angular clasts in a finer grained matrix. Mostly olivine (Fa30.2-31.0, FeO/MnO = 57.7) exhibiting 120° grain junctions, with interstitial troilite and Fe-Ni metal (30% Ni), and accessory orthopyroxene (Fs24.9-25.0Wo1.5-2.3, CaO for 2 analyzed grains are 0.76 and 1.16 wt.%, FeO/MnO = 37.6), chromite, chlorapatite, interstitial sodic feldspar (Ab85Or5), and fine-grained intergrowth patches. Silicate minerals contain trains of fluid inclusions. Rare relict chondrules are present. Oxygen isotopes (D. Rumble, CIW): analyses of two whole rock fragments by laser fluorination gave δ18O = +5.3 ± 0.1, δ17O = +4.0 ± 0.1, ∆17O = +1.22 ± 0.03 per mil. Specimens: type specimen, 20 g, and three polished thin sections, UWS; main mass, Hupé. Northwest Africa 974 Remlia, Morroco Found 2001 April Enstatite chondrite (E6) A single stone was found by villagers within 25 km of Remlia, Morocco, and was sold to a meteorite dealer in 2001 April. The original mass was 2250 g, but most of the rusty crust fell off and, therefore, only 1784 g are preseved. Classification and mineralogy (A. Jambon, UPVI): no visible chondrules and no evidence for melting; consists of anhedral enstatite (En>99) and kamacite (Fe93Ni6Si1); minor phases include, plagioclase (Ab82), oldhamite, daubreelite, alabandite,schreibersite, troilite, graphite and silica. Sulfides are oxidized to various degrees. Shock stage, S4. Based on the abundance of kamacite, classification as EH is suggested; yet, compositions of phases are not typical for EH chondrites and are possibly related to the high petrologic rade. Specimens: type specimen, 25 g, UPVI; main mass, Fectay. Northwest Africa 998 Algeria or Morocco Purchased 2001 September Martian meteorite (nakhlite) A. and G. Hupé (Hupé) purchased, from dealers at the Tucson Gem and Mineral Show in 2002 February, the main mass from a 456 g stone that had been acquired at an unspecified site in western Algeria or eastern Morocco in 2001 September. Dimensions before cutting: 72 mm by 65 mm by 48 mm. Classification and mineralogy (A. Irving and S. Kuehner, UWS): a friable, dark green rock with minor orange-brown alteration products that probably are of pre-terrestrial origin. It is composed mainly of subhedral, olive-green, complexly zoned subcalcic augite (Fs22Wo39) with subordinate yellow olivine (Fa64), orthopyroxene (Fs49Wo4), interstitial plagioclase (Ab61Or4 containing 0.1 wt. % SrO, and exhibiting normal birefringence), titanomagnetite, chlorapatite and pyrrhotite. The overall texture is that of a hypabyssal, adcumulate igneous rock, and the apparent crystallization sequence is olivine, orthopyroxene, titanomagnetite, augite, apatite, plagioclase. There is a weak preferred orientation of prismatic pyroxene crystals, many of which have very distinctive zoning, with cores of augite surrounded by irregular, inverted pigeonite rims (now consisting of orthopyroxene with fine augite lamellae). Trains of tiny melt inclusions are present along healed fractures within pyroxene; microprobe study confirms that most of these are K-Na-Al-bearing silicate glass, but some are intergrowths of glass and Fe-bearing carbonate, which may represent quenched immiscible silicate-carbonate liquids. Symplectitic intergrowths of titanomagnetite and low-Ca pyroxene are present at grain boundaries between large, discrete olivine and titanomagnetite grains, but are not present around chromian titanomagnetite inclusions within olivine. These observations suggest that a pre-terrestrial oxidation process produced the symplectites, and involved high temperature, deuteric fluid infiltration along grain boundaries; such fluids also may have produced the irregular pigeonitic rims on augite crystals. Secondary (probably pre-terrestrial) ankeritic carbonate, K-feldspar (some Fe-bearing), serpentine (?), calcite and a Ca sulfate are present on grain boundaries and within cracks in augite. Oxygen isotope composition (D. Rumble, CIW): replicate analyses of acidwashed augite by laser fluorination gave ä18O = +3.9 ± 0.2‰; ä17O = +2.4 ± 0.1‰; .17O = +0.30 ± 0.02‰. Specimens: type specimens, 20 g, UWS, 20 g, FMNH, and two polished thin sections, UWS; main mass, Hupé. Northwest Africa 1000 Morocco Purchased 2001 Achondrite (eucrite) One stone, which was probably recovered in Morocco, was purchased by D. Gregory. The stone has a reported total weight of 1200 g. Mineralogy and classification (P. Warren, UCLA): subophitic and slightly variolitic (fan-spherulitic) texture with laths of plagioclase (up to 4 mm long) and pyroxene (up to 5 mm). Pyroxenes are zoned from En68Wo4 to En16Wo26 with an offshoot from the main trend toward En40Wo3 resulting from a reaction of early pigeonite with intruded veins of fayalitic olivine (Fo16.25). About half of the plagioclase has been shock-altered to isotropic glass (maskelynite), average An83 (range An75.86, n = 29). Bulk composition and ratios of Ga/Al = 0.020 and Fe/Mn = 38 support its classification as eucrite (Warren, 2002). Moderately weathered as shown by carbonate veining. Specimens: type specimen, 22 g, and one thin section, UCLA; main mass, Gregory. Northwest Africa 1068 Morocco Found 2001 April Martian meteorite (basaltic shergottite) In 2001 April, meteorite hunters of the local team of "La Mémoire de la Terre" recovered 23 stones (one large mass, 522 g, and 22 small fragments, <20 g; total known mass, 576.77 g) in the Moroccan Sahara. Rocks are greenish-brown and partially coated by desert varnish; no fusion crust; cracks filled with terrestrial calcium carbonate. Thin shock veins and small melt pockets are abundant. Classification, mineralogy and bulk chemistry (J-A. Barrat, UAng; A. Jambon, UPVI; M. Bohn, I-CB; Ph. Gillet, ENSL; V. Sautter, MNHNP; Ch. Göpel, IPGP; M. Lesourd, SCIAM): consists of olivine (50 m to 2 mm) in a fine-grained groundmass (average grain size ~100 m) of euhedral to subhedral pyroxene crystals and interstitial maskelynite; minor phases are chromite, Ti-chromite, ilmenite, ulvöspinel, sulfides, merrillite, apatite, and a K-rich mesostasis; impact melt pockets (up to 1.5 mm long) contain pyrrhotite spherules. Modal abundances of impact melt pockets and calcite free areas: 52 vol% pyroxenes, 22% maskelynite, 21% olivine, 2% phosphates, 2% opaque oxides and sulfides, and 1% K-rich mesostasis. Mineralogy: olivine (Fa28 to Fa58); pyroxenes: pigeonite (En57Wo5Fs28 to En40Wo13Fs47; fe# (100 Fe/(Fe + Mg) = 29.54 atom%) and augite (En55Wo21Fs24 to En35Wo28Fs36; fe# = 29.51 atom%) are present as separate crystals in roughly equal volume proportions; maskelynite is zoned (An53Ab45Or2 to An49Ab48Or3) but is locally An-poor (An35Ab57Or8); FeO-rich merrillite (FeO 1.3 to 2.8 wt%); apatites, Cl 0.5.2.5 wt% and F 1.1.6.4 wt%; chromite have Ti-rich rims; ulvöspinels contain fine ilmenite lamellae (<1 m thick). An interstitial K-rich component, probably a shock-produced glass of alkali feldspar and silica, is generally associated with Fe-Ti oxides. Bulk chemistry: Al-poor ferroan basaltic rock, rich in MgO Meteoritical Bulletin, No. 86 A163 with major element abundances similar to those reported for EETA79001 lithology A. Key element weight ratios are Fe/Mn = 45, Al/Ti = 6.6, Na/Ti = 1.83, and Na/Al = 0.28. REE pattern is similar to Shergotty, Zagami, and Los Angeles. Specimens: type specimen, 20 g and 2 polished sections, ENSL; main mass, Fectay. Northwest Africa 1109 Morocco Purchased 2001 October/December Achondrite (eucrite, polymict) A. and G. Hupé (Hupé) purchased four stones totalling 2.54 kg from a Moroccan dealer in 2001 October and December, but the total weight of this material including that held by other collectors is estimated to be nearly 6 kg. The stones show distinctive white and grey mineral and lithic clasts in a light tan matrix Classification and mineralogy (A. Irving and S. Kuehner, UWS): polycrystalline clasts include basaltic eucrite (ophitic texture, variable grain size, mainly anorthite + pigeonite Wo16Fs57, FeO/MnO = 30); cumulate eucrite (coarse grained, equigranular, mainly anorthite + exsolved pigeonite with accessory silica); rare eucritic breccias and distinctive ferroan intergrowths (fayalite + hedenbergite + silica ± troilite). Mineral clasts include homogeneous pigeonite grains (Wo15Fs31, FeO/MnO = 26), pigeonite grains with clinopyroxene exsolution lamellae (FeO/MnO = 30-33), anorthitic plagioclase (Ab6-Ab10) and a silica polymorph. Accessory minerals in clasts and matrix include ilmenite, Fe metal, chromite, baddeleyite and apatite. Specimens: type specimen, 20 g, and four polished thin sections, UWS; main mass, Hupé. Northwest Africa 1110 Morocco Purchased 2001 November Martian meteorite (basaltic shergottite) G. and A. Hupe (Hupe) received a small sample of this meteorite in 2001 September and bought the rest from a dealer in Erfoud, Morocco in 2001 November. The weight of the total material purchased is 118 g. The place of recovery is believed to be in Morocco. Classification and mineralogy (A. Irving and S. Kuehner, UWS): consists of olivine phenocrysts in a fine-grained groundmass of complexly zoned pigeonite and homogenous maskelynite, Ab46Or2, with minor ilmenite, Ti-magnetite and pyrrhotite. Euhedral to subhedral olivine has Mg-rich cores (Fa28, FeO/MnO = 50) and narrow Fe-rich rims (Fa51, FeO/MnO = 53) and contains inclusions of chromite and glass; augite (Fs33Wo21) occurs as rare inclusions in olivine; pigeonite is zoned, Fs28Wo9 to Fs40Wo15 and FeO/MnO = 30; presence of rare chlorapatite in mesostasis. Secondary features include minor barite, commonly associated with chromite inclusions in olivine; calcite, in a crosscutting glass veinlet; and narrow zones of K-Al-bearing glass or clay minerals along grain boundaries between pyoxene and maskelynite. Mineral composition indicates that this rock is possibly paired with NWA 1068. Specimens: type specimen, 20 g and several thin sections, UWS; main mass, Hupe.

Northwest Africa 1150 Morocco Purchased 2000 Achondrite (howardite) A 67.1 g stone was purchased in Tagounite, Morocco, by a meteorite collector. Classification and mineralogy (T. Bunch and J. Wittke, NAU): modal analyses on 24 cm2 show that 93 vol% of the clasts are diogenites, 7 vol% are basaltic eucrites. Diogenitic pyroxenes range from Fs28.1Wo2.5 to Fs7.8Wo11.3; plagioclase, An85.95 with ilmenite, chromite and sulfides. Eucrite pyroxenes range from Fs38Wo6 to Fs47.4Wo16.7; plagioclase, An88.92, with chromite (TiO2 = 0.68. 3.48 wt%), troilite, and silica. Low weathering grade, W1.

Northwest Africa 1052 Morocco Found 2001 Acapulcoite A stone of 22 g was bought in Erfoud (Morocco) by Matteo Chinellato. Classification and mineralogy (G.Pratesi, V.Moggi- Cecchi, L. Mancini, MSP: petrography and EMPA; G. Sighinolfi and S. Lugli, UMo: EMPA): either thin section and type specimen sample look to be composed by a fine grained aggregate. In thin section it displays an granular texture with grains mainly represented by olivine, pyroxene, Fe,Ni alloy and troilite and ranging from 200 to 700 µm in dimensions. Olivine is homogeneous and has a typical forsteritic composition, (Fa = 5.95 mol %); orthopyroxene Fs = 7.60, Wo = 1.44 mol %. High Ca-pyroxene (Fs = 3.63, En = 51.11, Wo = 45.26, Al = 1.44 mol %) and plagioclase (An = 13.73, Ab = 79.90, Or = 6.37 mol %) are also common. Apart from silicates, major phases are metal and troilite. Accessory phases include Na- and Ca-Merrillite and magnesiochromite (Cr/(Cr+Al) = 0.91; Fe:Mn:Mg ratios = 0.58:0.09:0.33). This meteorite shows a recrystallization texture with abundant 120° triple junctions and many interstices filled with metal. Based on texture (fine-grained), mineralogy and chemistry (Cr content of diopside varying from 1.18 to 1.43 wt. %) the meteorite is classified as an acapulcoite. Terrestrial weathering grade is rather low (W1); optical features (sharp extinction of olivine) indicate that the sample is very weakly or not shocked (S1). Specimens: main mass with buyer (Matteo Chinellato); type specimen (4.7 g) and thin section, MSP. Northwest Africa 1054 Morocco Found 2001 Acapulcoite A stone of 86 g was bought in Erfoud (Morocco) by an anonymous dealer. Classification and mineralogy (G.Pratesi, V.Moggi-Cecchi, L. Mancini, MSP: petrography and EMPA; G. Sighinolfi and S. Lugli, UMo: EMPA): composed of a finegrained aggregate. In thin section it displays an granular texture with grains mainly represented by olivine, pyroxene, Fe,Ni alloy and troilite and ranging from 200 to 700 µm in dimensions. Olivine is homogeneous and has a typical forsteritic composition, (Fa = 6.37 mol %); orthopyroxene is bronzitic (Fs = 7.77, Wo = 1.32 mol %).

This meteorite shows a recrystallization texture with abundant 120° triple junctions and many interstices filled with metal. Based on texture (fine grained), mineralogy and chemistry (Cr content of diopside varying from 1.17 to 1.35 wt. %) the meteorite is classified as an acapulcoite. Terrestrial weathering grade is rather low (W1); optical features (sharp extinction of olivine) indicate that the sample is very weakly or not shocked (S1). The meteorite may be paired with NWA 1052.

Northwest Africa 1180 Morocco Found 2000 Carbonaceous chondrite (CR2) Eight fully to mostly crusted stones, weighing a total of 1705 g, were purchased in Rissani (2001). The local finders say that these stones defined a strewnfield ~1.5 km long and within a few kilometers of Zagora. Classification and mineralogy (T. Bunch and J. Wittke, NAU): chondrules account for 63 vol%; small chondrules (<1.5 mm) tend to be round and metal-poor, large chondrules (<4.0 mm) are mostly irregularly shaped with abundant metal (kamacite = 5.2.6.0 wt% Ni). Olivine, Fa1.3.2.1; orthopyroxene, Fs2.2.3.2Wo0.8; plagioclase, An95.97; pyrrhotite (Ni = 1.4 wt%); phyllosilicates, serpentine-greenalite series (Mg > Fe); chondrule and matrix glasses are Mg, Al-rich, Na, K-poor; fine-grained (<0.05 mm) refractory inclusions contain diopside (Wo49.52, Fs1), spinel (FeO = 0.25 wt%), and gehlenite. Shock stage, S1; weathering grade, W2. Specimens: type specimen, 19.7 g and one thin section, NAU; main mass is with the purchaser. Northwest Africa 1181 Morocco Found 2001 Achondrite (polymict eucrite) A 3279 g, crusted stone was purchased in Rissani, in 2001. Classification and mineralogy (T. Bunch and J. Wittke, NAU): modal analyses (area of 34 cm2), eucritic basalts, 94 vol%; shock melt clasts, 4 vol%, diogenites, 2 vol%. At least 34 different eucrite clasts were observed that range from micro-ophitic/subophitic (<0.1 mm) to cumulate to very coarse-grained gabbroic(3.7 mm). Gabbro pyroxenes are predominantly 2.5 mm in size, subcalcic ferroaugites (TiO2, 0.9 to 2.1 wt%) with 3.6 mm plagioclase, An92; ilmenite, chromite (Al2O3 = 9.2 wt%), and acicular crystals of tridymite up to 7 mm in length.

Northwest Africa 1182 Morocco Found 1999 Achondrite (howardite) A 780 g, mostly crusted specimen, was purchased in Morocco in 2000. Classification and mineralogy (T. Bunch and J. Wittke, NAU): medium clast size (<1.5 cm); clast modal analyses of 22 cm2 yield: diogenites, 82 vol%; ophitic to subophitic basalts, 12%; shock melt, 4%; others, 2%. Diogenite clasts, orthopyroxene (Fs24Wo1.5) predominant over pigeonite (Fs30Wo8), plagioclase, An96, ilmenite, chromite and pyrrhotite. Shock stage, S2; weathering grade, W1. Specimens: type specimen, 20.3 g and one thin section, NAU; main mass is with the purchaser. Northwest Africa 1195 Morocco Purchased 2002 March/April Martian meteorite (basaltic shergottite) A. and G. Hupé (Hupé) purchased a 50 g fragment of a broken stone with a distinctive, thin weathering rind collected by nomads near Safsaf, Morocco in 2002 March, and subsequently purchased the remainder of the same elongated stone (total weight 315 g). Dimensions of the reassembled stone are 133 mm × 43 mm × 37 mm. Classification and mineralogy (A. Irving and S. Kuehner, UWS): olivine megacrysts (up to 4 mm) are set in a groundmass of low-Ca pyroxene and maskelynite (Ab37Or0.5 to Ab41Or0.7) with minor Tichromite, pyrrhotite, ilmenite and Mg-bearing merrillite. The euhedral to subhedral shapes of most of the olivine grains suggest that they are phenocrysts rather than xenocrysts. Olivine exhibits strong compositional zoning (cores Fa19, FeO/MnO = 54; rims Fa40, FeO/MnO = 62), and contains abundant inclusions of chromite, clinopyroxene, orthopyroxene and pyrrhotite. The groundmass low- Ca pyroxenes are zoned from cores of pigeonite (Wo7Fs26, FeO/MnO = 37.1) or, less commonly, orthopyroxene (Wo4Fs23, FeO/MnO = 37.0) to rims of more Fe-rich pigeonite (Wo12Fs33, FeO/MnO = 36.6). Occurring very rarely on groundmass pyroxene grains are patchy overgrowths of an Fe-rich mineral (possibly related to chamosite or chlorite, with 35 wt. % FeO, 5 wt. % Al2O3, 1.5 wt. % MgO and a low oxide sum of 85 wt. %, suggesting the presence of water or hydroxyl). Calcite occurs sparsely along grain boundaries and as thin veinlets. Texture and mineral compositions are similar to those in olivine-phyric basaltic shergottite DaG 476/670, but olivine is much more magnesian than in other olivinephyric basaltic shergottites SaU 005/008 and NWA 1068/1110. Specimens: type specimen, 20 g, and two polished thin sections, UWS; main mass, Hupé Northwest Africa 1235 Northwest Africa Found 2000 Enstatite achondrite (possibly anomalous aubrite) The 80 g individual has a dark brown fusion crust. Mineralogy and description (C. A. Lorenz, Vernad): medium-grained subophitic rock consisting of Fe-poor enstatite, En99Wo1 (76 vol%), feldspar An74.8.95.6Or0.6.6.8 (8 vol%), minor silica (1 vol%) and 15 vol% of Si-bearing Fe metal, schreibersite, Cr-bearing troilite and rust. Accessory minerals are oldhamite, ferromagnesian alabandite, sphalerite, Fe-Ni metal, taenite, carbon phase, Fe-Ni-Cralloy, Sb- and Ag-sulfides. The meteorite bears some similarities with Itqiy. Shock stage is S2/3, weathering stage is W3/4. Specimens: type specimen, 16.6 g and two polished thin sections, Vernad; main mass is with the anonymous finder. Northwest Africa 1239 Northwest Africa Found 2001 Achondrite (diogenite) A single stone of 237 g was bought in Zagora in 2001 May. The meteorite is a polymict breccia that contains more than 90 vol% orthopyroxene fragments. Classification and mineralogy (J-A. Barrat, A164 Russell et al. UAng; M. Bohn, I-CB; V. Sautter, MNHNP; Ph. Gillet, ENSL): typical orthopyoxene, En70.72Wo2 (FeO/MnO molar = 32), but many more ferroan grains exist, contains inverted pyroxenes of eucritic origin, Fs27Wo45 to Fs64Wo2 and Fs22Wo44 to Fs51Wo1 (two grains), calcic plagioclase, An94-An81, olivine, Fa40.Fa55, metal, pure Fe and FeNi, and troilite. Specimens: type specimen, 22 g and one polished thin section, ENSL; main mass is with the anonymous purchaser. Northwest Africa 1240 Northwest Africa Found 2001 Achondrite (eucrite, anomalous) A single stone of 98 g was bought in Zagora in 2001 November. Classification and mineralogy (J-A. Barrat, UAng; A. Jambon, UPVI; M. Bohn, I-CB; V. Sautter, MNHNP; Ph. Gillet, ENSL; Ch. Göpel, IPGP; F. Keller, LGCA): the meteorite has the texture of an unbrecciated achondrite consisting of skeletal low-Ca pyroxene phenocrysts in a variolitic (fan-spherulitic) mesostasis of pyroxenes, plagioclase, and accessory skeletal chromite, iron, silica, fayalite, troilite and phosphate. The rock resembles some Apollo 15 pigeonite basalts but mineral and bulk rock compositions indicate a relationship to eucrites. Pyroxenes (FeO/MnO molar = 31, n = 540) are unequilibrated and comprise a compositional range wider than in any other HED meteorite with phenocryst cores, En76Fs22.1Wo1.9, and mesostasis pyroxenes (pyroxferroite?), En0.3Fs83.4Wo16.3; plagioclase, An90.9 (n = 122), range, An88 to An92. Bulk composition: Mg-rich Kapoeta-like clasts; slightly depleted in light REEs similar to the cumulate eucrite Moore County; possibly an impact-melted cumulate eucrite. Specimens: type specimen, 17 g and one polished thin section, ENSL; main mass is with the anonymous purchaser. Northwest Africa 1241 ........................~27°N, ~16°E Libya Found 2001 August 11 Achondrite (ureilite) A single stone of 282 g was found by an anonymous finder in the Libyan desert. Classification and mineralogy (F. Wlotzka, MPI, and M. Kurz, Kurz): coarse olivine and pigeonite grains (up to 1 mm) are set in a pavement texture of smaller olivines containing finely dispersed metal grains. Coarser white reflecting grains are suessite, (Fe,Ni)3Si, with 13 wt% Si, 2.5 wt% Ni (range 1.4 wt%), and 1.1 wt% Cr. This mineral is abundant and occurs in blocky grains or interstial vein-like forms. No kamacite and no troilite were found. Olivine cores, Fa17.20 (0.7.1.7 wt% Cr2O3, 0.2.0.6 wt% CaO), rims are reduced to Fa1.10; pigeonite, Fs4.22Wo4.15En74.87, and 0.6.1.2 wt% Cr2O3. Carbonaceous matrix is rare, graphite occurs in fine-grained patches. The stone is, in contrast to North Haig, not brecciated. Weathering is minor, except for carbonate and oxide veins. Specimens: type specimen, 20.5 g, MPI; main mass is with the anonymous finder. Northwest Africa 1242 Gillio, Libya Found 1985 Mesosiderite Two fully ablated pieces of a mesosiderite (total known weight ~7 kg) were found near the village of Gillio by unknown oil exploration workers and put into service as bookends for 13 years. Purchased in 1998 by an anonymous dealer. Reports of a strewn field are presently unconfirmed. Classification and mineralogy (T. Bunch and J. Wittke, NAU): type 2A; contains scarce, metal nodules up to 19 mm in diameter; Mg-rich pyroxene overgrowths on Ca-pyroxene clasts; moderate resorption of plagioclase. Orthopyroxene (Fs33Wo3) replaces pigeonite (Fs34Wo8) and exsolved augite (Fs43Wo42); plagioclase (An92); pyrrhotite, chromite (Al2O3 = 8.4 wt%); kamacite, 5.8 wt% Ni; rare taenite (42 wt% Ni), silica and phosphate. Shock stage, S1; weathering grade, W0. Specimens: type specimen, 20.2 g thin section, NAU; main mass is with the anonymous purchaser. Northwest Africa 1284 Morocco Found 2001 Carbonaceous chondrite (CK4/5) A 56 g stone was purchased in Erfoud in October 2001. Classification and mineralogy (J. Wittke and T. Bunch, NAU): mostly recrystallized olivine-rich matrix with poorly crystallized plagioclase (mottled extinction, low birefringence, and up to 0.12 wt % NiO). Matrix olivine, Fa31.5 (range, Fa31.1-32.0) (0.45 wt % NiO); plagioclase, An51.8Or5 (range An44.5 – 63.1); magnetite, 4.6 wt % Cr2O3; 1.62 % Al2O3; 0.31 % NiO; 0.37 % TiO2; 0.25 % CoO and 0.17 % MnO. Contains minor pentlandite, pyrrhotite, and phosphate. Low degree of weathering and shock level, S2. Specimens: 11.3 g, NAU; main mass, Hupe. Northwest Africa 1296 Morocco Found 2001 spring Achondrite (angrite) The single stone weighs 810 g and appears quite fresh with a very thin and shiny, dark-grey, typical fusion crust. It was found in Morocco in spring 2001 by an anonymous finder and afterwards bought by a dealer in Bouarfa (Morocco). Petrography, mineralogy, chemistry and classification (A. Jambon, UPVI; J.-A. Barrat, UAng; O. Boudouma, UPVI): The rock has a fine-grained magmatic texture, indicating rapid cooling, and is significantly different from other angrites. Numerous small vesicles are present, some of which filled with carbonate. Olivine (˜ Fo50) was the first phase to crystallize, as feathery chains a few micrometers in thickness. It is closely associated with anorthite (An98-100) overgrowing the olivine crystals. These composite chains are separated from one another by intergrown elongated fassaitic pyroxenes. Both olivine and pyroxene are normally zoned up to mg# <0.01. The most magnesian pyroxene and olivine have mg# of 0.52. The Fe-rich olivines also contain up to 12 wt. % CaO, a typical feature of angrites; they appeared after plagioclase crystallization stopped at the end of the crystallization sequence when co-crystallization of olivine with sub-calcic kirschsteinite is observed. Minor phases are pyrrhotite, Caphosphate, a silico-phosphate similar to that found in d'Orbigny and titanomagnetite. The bulk rock analysis is that of a typical angrite like d'Orbigny or Sahara 99555, with a (Ca/Al)CI of 1.52. Extensive trace element data confirm that alkali elements are strongly depleted. Ba is slightly enriched probably as a result of terrestrial alteration; Sr is not. All refractory lithophile incompatible elements exhibit a flat chondrite normalized pattern with an enrichment of 13 × CI. Specimens: main mass, Moroccan Import, Asnières, France; type specimen, 49 g, UPVI. Northwest Africa 1457 Morocco Purchased 2001 December Achondrite (winonaite) Seven small stones with a total weight of 52 g were purchased from a Moroccan dealer by A. and G. Hupé (Hupé) in 2001 December. Classification and mineralogy (A. Irving and S. Kuehner, UWS): medium-grained, equilibrated metamorphic texture with triple junctions among mineral grains. Abundant enstatite (Fs6Wo1.5, FeO/MnO = 15) and forsteritic olivine (Fa5, FeO/MnO = 18) with subordinate diopside (Fs2.8Wo44, FeO/MnO = 8), sodic plagioclase (Ab82Or4), Ni-poor Fe-Ni metal, troilite, schreibersite, Cr-rich chromite and Cl-rich apatite. Daubreelite occurs as blades within some troilite grains. Rare chromite grains (up to 20 m; 66 wt.% Cr2O3; Cr/(Cr+Al) = 0.870; Mg/(Mg+Fe) = 0.682) are associated with troilite. Grain boundaries are veined by heterogeneous Ni-free iron oxides and/or hydroxides. Oxygen isotope composition (D. Rumble, CIW): analyses of two whole rock fragments by laser fluorination gave d18O = +5.1 ± 0.1‰; d17O = +2.3 ± 0.1‰; .17O = -0.40 ± 0.03‰. The texture, mineralogy and oxygen isotopic composition of this sample match the criteria for winonaites given by Benedix et al. (1998).

Classification and mineralogy (A. Irving and S. Kuehner, UWS): Coarse-grained cataclastic protogranular texture. Subequal amounts of orthopyroxene (Fs28Wo4.7 to Fs30Wo6.5, FeO/MnO = 28-32) and olivine (Fa36; FeO/MnO = 46.5), with minor chromite (Cr/(Cr+Al) =0.62 cores to 0.66 rims), anorthitic plagioclase (Ab6.8-Ab9.3), troilite, and metal (0.06 wt.% Ni). Some orthopyroxene grains (up to 10 mm) have sparse exsolution lamellae of clinopyroxene (Fs10Wo46 to Fs11Wo45, FeO/MnO = 28- 32). Some olivine grains (up to 8 mm) have multiple tilt-boundaries. Irregular areas along grain boundaries are composed of symplectitic intergrowths of chromite and orthopyroxene. Oxygen isotope composition (D.

The clasts resemble diogenites, cumulate and basaltic eucrites in mineral composition and texture. Medium-grained cumulate eucrite clasts of ophitic texture consist of plagioclase (An91-94) and pigeonite (Wo5-10, En37-52), minor orthopyroxene (Wo3, En53) and Ti-rich chromite. Basaltic eucrite clasts with a sub-ophitic texture contain extremely iron-rich augite (possibly pyroxferroite; Wo16-31, En3-8), plagioclase (An82-87), a silica phase and Ti-rich chromite. Sparse (< 5 vol%) diogenitic clasts consist of orthopyroxene (Wo2- 5). Pyroxene Fe/Mn range from 27-33. The possible pyroxferroite grains have Fe/Mn 27-45. Matrix is pyroxene (pigeonite, augite and orthopyroxene), minor olivine, Fe-rich sulfides, Ti-rich chromite and rare spherules of glass; one zircon grain was observed; one symplectitic grain composed of silica, augite and fayalite is interpreted to be the result of pyroxferroite break-down.
