Martian basalt (shergottite)

A dark-brown stone of 2146 g was found in Dar al Gani. Mineralogy and classification: devoid of fusion crust; porphyritic basaltic texture consisting of millimeter-sized phenocrysts of brown olivine (Fo_61–78, Mn/Fe = 0.021–0.025 atomic) set in a more fine grained matrix of pigeonite laths (En_57–72 Wo_5–15, Mn/Fe = 0.030–0.038 atomic) and interstitial feldspathic glass (An_56–67Ab_33–43); minor mineral components include augite, chromite, Ti-rich chromite, ilmenite, merrillite and pyrrhotite; texture, mineral modes and chemistry close to EETA79001 lithology A; shock deformation features include twinning in pigeonite, strong mosaicism and planar deformation features in olivine, and abundant impact-melt pockets and veinlets; pervasive veins filled in by calcite are due to terrestrial weathering. Oxygen isotopes: d¹⁷O = 2.895, d¹⁸O = 4.980, and D¹⁷O = 0.305‰. The petrography, mineralogy, and noble gas chemistry of DaG 476 and DaG 489 are very similar, and the two are likely paired.

Martian basalt (shergottite)

A brownish gray stone weighing 1056 g was found in the desert. Mineralogy and classification (M. Nazarov and M. Ivanova, Vernad; L. A. Taylor, UTenn): fusion crust absent; meteorite is a doleritic rock consisting of subhedral grains (0.2–0.5 mm) of pigeonite (Wo_{9–1 5} En_40–70, Fe/Mn = 20–40 at), augite (Wo_30–40 En_40–55), olivine (Fo_25–60, Fe/Mn = 50–60 at), and feldspar (An_36–68) converted to maskelynite; olivine has higher Fe/Mg than that of coexisting pyroxenes, as it is in nakhlites; mineral modes (approximate volume percent) are pyroxene = 65, maskelynite = 25, and olivine = 10, with accessory silica, K-rich feldspar, whitlockite, chlorapatite, chromite, ilmenite, titanomagnetite, magnetite, and pyrrhotite; secondary phases are calcite, gypsum, smectite, celestite, and Fe hydroxides; shock features include fracturing and mosaicism, maskelynite, and rare impact-melt pockets; extensive terrestrial weathering present mainly as carbonate veins crosscutting the meteorite, however, there are smectite–calcite–gypsum "orangettes" replacing maskelynite, which are similar to those in Allan Hills 84001 and could be of martian origin; bulk chemistry close to Shergotty, with light rare earth elements strongly depleted.

Lunar meteorite (impact melt breccia)

A 1015 g stone was purchased on 2001 January 10 in Alnif, Morocco, by Michael Farmer. The exact location of find is unknown but it is possibly in Algeria. The stone is complete, oriented, and appears relatively unweathered. Classification and mineralogy (A. Rubin and P. Warren, UCLA; D. Kring and I. Daubar, UAz): texture is typical of a crystalline impact melt breccia (polymict) with highland affinities; glassy and vesicular melt veins and melt pockets indicate shock subsequent to compaction by an impact event; plagioclase, An_95.7Ab_4.09Or_0.17 (n = 136, UAz); olivine, Fo_65–68 (average Fo₆₆) with FeO/MnO = 88 ± 7 g/g (UCLA); olivine Fo_68.4 with FeO/MnO = 93.9 ± 7.7 g/g (range: 78.7 to 111) (n = 51, UAz); pyroxene, Fs25Wo17 with nearly uniform Mg/(Mg + Fe) = 67–68 mol% and FeO/MnO = 51 ± 6 g/g (n = 10, UCLA); pyroxene, Wo10.3–51En32.6–63.9 Fs42.6–14.2, mean Mg/(Mg + Fe) = 68 mol%, FeO/MnO = 52 ± 8 g/g (n = 28, UAz); glassy melt veins occur in both UCLA and UAz samples; a 0.1 mm vein (UCLA) has SiO2 = 44.3 wt%, Na2O = 0.3 wt%, Al2O3 = 30.0 wt%, FeO = 3.6 wt%, MgO = 3.9 wt%, CaO = 17.3 wt%, and TiO2 = 0.3 wt%, which may approximate the bulk meteorite composition.

Martian meteorite (nakhlite)

A. and G. Hupé (xHupé) 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 acid-washed augite by laser fluorination gave δ¹⁸O = +3.9 ± 0.2‰; δ¹⁷O = +2.4 ± 0.1‰; ∆¹⁷O = +0.30 ± 0.02‰.

Achondrite (lunar, mare basalt/gabbro breccia)

History: Four stones of 30.6 g, 11.6 g, 64 g, and 85 g were purchased from Moroccan dealers in Erfoud for a consortium of North American collectors in June and July of 2005.

Petrography and Geochemistry: (T. Bunch and J. Wittke, NAU; A. Irving and S. Kuehner, UWS; R. Korotev, WUSL) All stones are very similar and consist of clast-dominated polymict breccias composed of >80 vol% olivine-phyric basalt and gabbroic/diabasic clasts (0.2 cm to several cm across) within a finer breccia matrix. The basalt clasts show a wide range in mineral compositions, but all contain phenocrysts of olivine (Fa_28–99; FeO/MnO = 98.9) and some also have phenocrysts of pyroxferroite or chromite all in a fine-grained matrix consisting of intergrown pigeonite, pyroxferroite, K-Ba feldspar, ilmenite, merrillite, baddeleyite, troilite, silica, and glass. The gabbroic clasts range in texture from coarser-grained (>3 mm) hypidiomorphic gabbro to finer-grained (~1 mm) diabasic clasts. Both types of gabbroic lithologies consist mainly of pigeonite (Fs_23.3–31.3Wo_8.7–11.5; FeO/MnO = 60–69) and subhedral to anhedral olivine (Fa_34.1–41; FeO/MnO = 85– 99) with less abundant augite (Fs_24.1–47.5Wo_24.4–32.1) and partly maskelynite, blocky to tabular plagioclase (An_81–94). The breccia matrix consists mainly of gabbroic debris with fragments of basalt, silica polymorph, symplectites, subparallel intergrowths of anorthite + pyroxferroite + ilmenite and shock-melted material. Bulk compositions: (R. Korotev, WUSL) INAA of 11 subsamples show that they vary considerably in bulk composition, with the most Fe-rich subsample nearly indistinguishable from NWA 3160 basalt. All other subsamples are compositionally equivalent to mixtures of NWA 3160 basalt and the regolith breccia lithology of NWA 773, but with slightly lower concentrations of incompatible elements. Note: Based on petrography, mineral compositions, and bulk compositions, these stones are paired with NWA 3160 and may be paired with NWA 773.

Achondrite (Martian, chassignite)

History: In August 2000, meteorite collectors discovered a stone fragmented into nine pieces (308 g, 128 g, 74 g, 47 g, 38 g, 6.4 g, 3.3 g, 2.0 g, and 4.3 g for a total mass of 611 g) in the western part of the Sahara.

Petrography and Geochemistry: (P. Beck, Ph. Gillet, B. Reynard, B. van de Moortele, ENSL; J.A. Barrat, M. Bohn, I. Cotton, UBO) Olivine (Fo78.2–79.1; Mn/Fe = 0.018; ~89.6 vol%), chromite (4.6 vol%), low-Ca pyroxene (En_78.5Wo_2.7Fs_18.8 to En_76.6Wo_3.2Fs_20.2), high-Ca pyroxenes (En_73.5Wo_8.0Fs_18.5 to En_64.0Wo_22.1Fs_13.9; Mn/Fe 0.030 [total of low- and high-Ca pyroxene ~4.1 vol%]), and sanidine glass (~1.6 vol%) with traces of apatite. The texture is that of a cumulate dominated by mm-size anhedral to subhedral olivine crystals, sometimes poikilitically enclosed in augite (En_54.6Wo_32.8Fs_12.6 to En_46.7Wo_44.1Fs_9.2). Oxygen isotopes: (I. Franchi, R. Greenwood, OU) δ¹⁷O = 2.40, δ¹⁸O = 4.02, ∆¹⁷O = 0.315; δ¹⁷O = 2.30, δ¹⁸O = 3.85, ∆¹⁷O = 0.295 (all ‰, n = 2). Furthermore, NWA 2737 displays trace element abundances similar to Chassigny. For example, its REE pattern resembles that of Chassigny but with a more pronounced LREE enrichment.

Achondrite (lunar, gabbro)

History: A single minimally weathered fusion-encrusted stone of 233 g was purchased from a Moroccan dealer in Tagounite, Morocco, by M. Farmer in November 2005.

Petrography and Geochemistry: (J. Wittke and T. Bunch, NAU; A. Irving, UWS) The specimen consists of a single yellow-green, relatively coarse-grained rock traversed by thin, black glass-rich veins. It is an olivine-rich, two-pyroxene cumulate gabbro composed of olivine (Fa_31.7; FeO/ MnO = 96; 52 vol%), (Fs_26.6Wo_6.7; 23 vol%), augite (Fs_16.2Wo₂₉; 9 vol%), and plagioclase (An₅₆; 14 vol%) with minor amounts of Ba-K feldspar, chromite, ilmenite, and merrillite. Larger pigeonite grains commonly enclose equant olivine grains, which contain abundant melt inclusions (0.025–0.125 mm). Plagioclase is partially converted to maskelynite, and pyroxenes and olivine exhibit shock lamellae and undulatory extinction. Note: This specimen is identical in texture and mineral composition to the gabbro clasts in NWA 773 and NWA 2700 and thus appears to be paired with those breccia specimens.

Classification: Achondrite (lunar, gabbro); minimal weathering.

Achondrite (lunar, feldspathic granulitic impactite)

History: In August 2005, G. Hupé purchased a 1634 g stone from a Moroccan dealer in Ouarzazate.

Petrography and Geochemistry: (A. Irving and S. Kuehner, UWS) The exterior is almost completely coated by a thin, transparent, greenish fusion crust. The pale gray interior has multiple shock fractures (with very minor calcite coatings) and some thin glass veins. Poikiloblastic recrystallized breccia, with larger grains of plagioclase (~70 vol%) enclosing much smaller grains (less than 100 µm across) of pyroxenes (~20 vol%), olivine (~10 vol%), and accessory Ti-chromite (Cr/(Cr+Al) = 0.714–0.736; Mg/(Mg+Fe) = 0.121– 0.143; TiO₂ = 9.1–18.4 wt%), ilmenite, troilite, and metal (Ni = ~15 wt%). Anorthitic plagioclase (An_97.4–98.2) has been converted by shock almost entirely to maskelynite (although domains of birefringent, less-shocked feldspar remain). Pigeonitic pyroxene grains have very fine-scale exsolution lamellae of augite (Fs_14.5–16.1Wo_40.2–40.5; FeO/MnO = 41.7– 43.8) within orthopyroxene (Fs_32.0–33.9Wo_4.4–5.8; FeO/MnO = 55.5–61.2). Olivine (Fa_38.0–40.9; FeO/MnO = 91.7–110).

Achondrite (lunar, mingled basalt-rich breccia)

History: Purchased by Greg Hupé in July 2007 from a dealer in Tagounite, Morocco.

Physical characteristics: A single stone (42 g) partially covered by black fusion crust; interior slices show it to be a breccia composed of white, beige, and light gray clasts in a dark gray matrix (Fig. 3).

Petrography: (A. Irving and S. Kuehner, UWS) Regolithic breccia composed of abundant angular mineral and lithic clasts in a sparse vesicular, glassy matrix. Mineral fragments include calcic plagioclase, pigeonite, augite, Ti chromite, ilmenite (one with a tiny baddeleyite inclusion) and silica polymorph. Lithic clasts include several types of mare basalt (a coarse-grained example is composed of olivine + zoned pigeonite + calcic plagioclase + ilmenite + troilite), granophyric intergrowths of Fe-rich augite + fayalitic olivine + silica polymorph, a coarse-grained dunitic or troctolitic rock containing a large metal grain (associated with rutile and secondary ilmenite), and a large "breccia-within-breccia" clast. Mare basalt clasts and debris are predominant over highlands lithologies.

Geochemistry: Olivine clasts (Fa_37.0-37.7; FeO/MnO = 94- 98), olivine in basalt clast (Fa_87.9; FeO/MnO = 89), plagioclase (An_92.4-95.3Or_0.5-0.1), pigeonite host (Fs_52.3Wo_10.5; FeO/MnO = 65.2), augite lamella (Fs_31.9Wo_31.9; FeO/MnO = 60.3), pigeonite clast (Fs_60.1Wo_7.0; FeO/MnO = 71.1), augite clast (Fs_17.2Wo_36.9; FeO/MnO = 53.3). Bulk composition: (R. Korotev, WUSL) FeO = 13.7 wt%; Sm = 3.1 ppm, Th = 0.9 ppm, Ir = 3.4 ppb.

History: Purchased by Greg Hupé in July 2008 from a dealer in Ouarzazate, Morocco, who reported that these stones were found in the same area as NWA 4936 near Siksou Mountain in southern Morocco.

Physical characteristics: Six, dark gray, mostly very fine-grained stones (total weight 281 g) with hackly fracture and lacking obvious fusion crust. The interior of each stone resembles devitrified glass with dispersed small white clasts.
Petrography: (A. Irving and S. Kuehner, UWS) All specimens are composed of small mineral clasts and sparse lithic clasts in a very fine-grained matrix (which has the texture of an impact melt with heterogeneous, “swirly” glass). Mineral clasts include anorthite, olivine, pigeonite, subcalcic augite, ilmenite, troilite, and irregular-shaped grains of kamacite.

Geochemistry: Pigeonite (Fs_34.7Wo_9.8, FeO/MnO = 59.9), augite (Fs_55.8Wo_26.4, FeO/MnO = 72.6), olivine (Fa_25.7–27.0, FeO/MnO = 85.3–120), plagioclase (An_96.2–97.2Or_0.0). Bulk composition (R. Korotev, WUSL): FeO 5.8 wt%, Th 2.0 ppm, Sc 9.1 ppm, Ni 520 ppm, Sm 6.3 ppm.

Classification: Achondrite (lunar, feldspathic breccia). These stones have essentially the same distinctive textures, mineral compositions and bulk composition as NWA 4936, and are almost certainly paired with the latter stones.
