Amgala 001 26.014°N, 11.020°W
Saguia el Hamra, Western Sahara
Purchased: 2022 Dec
Classification: Martian meteorite (Shergottite)
History: Multiple stones were found together in December 2022 near Meharrize. Said Muftah Bachir and Ziyao Wang bought 12 kg together from the finders, including the largest 5200 g individual; Mark Lyon acquired 19165 g from two different dealers; Aziz Habibi obtained 3500 g from another dealer.
Physical characteristics: Weathered exterior surfaces of the stones are brown with a distinctive knobby appearance. Fresh interiors are greenish-gray with darker olivine phenocrysts visible.
Petrography: (A. Irving, UWS, and P. Carpenter, WUSL) Zoned olivine phenocrysts (up to 2 mm in length) are set in a groundmass with variable grainsize composed predominantly of prismatic, zoned clinopyroxene and lath-like maskelynite, together with accessory alkali feldspar, pyrrhotite, ulvöspinel, chromite (with variable Ti content), ilmenite, baddeleyite and chlorapatite. Thin opaque shock veins crosscut the specimen as well as secondary calcite veinlets. Olivine phenocrysts contain small patches of alteration products (red-brown in thin section).
Geochemistry: Olivine (Fa31.7-56.6, FeO/MnO = 52-55, N = 5), pigeonite (Fs27.7-48.4Wo10.4-9.8, FeO/MnO = 29-35, N = 3), subcalcic augite (Fs20.7-30.4Wo32.5-34.6, FeO/MnO = 28-32, N = 2), maskelynite (An47.4-50.5Or2.2-1.7, N = 2), alkali feldspar (Ab49.4Or34.0An16.7).
Classification: Shergottite (olivine-phyric).
Specimens: 68.3 g including one polished thin section at UWB; remainder with Mr. S. Bachir/WangZ (12 kg), Mr. M. Lyon (19165 g) and Mr. A. Habibi (3500 g).

Plateau du Tademait 008 28°55’03.8″N, 0°59’05.6″E
Adrar, Algeria
Purchased: 2022
Classification: Martian meteorite (Shergottite)
History: Purchased from Algerian dealer Ali Mftah Mftah by Mark Lyon in 2022.
Physical characteristics: Single stone with patches of black fusion crust, sandblasted surfaces show exposed olivine phenocrysts. A polished slice reveals numerous pale green olivine phenocrysts up to ~1 cm in diameter that poikilitically enclose smaller pyroxene grains. The groundmass consists of dark gray pyroxene grains up to 500 μm and smaller olivine grains.
Petrography: (C. Agee, UNM) This meteorite has the approximate modal abundances: 50% clinopyroxene, 25% olivine, 10% maskelynite, with accessory ilmenite, chromite, Ti-Cr spinel, and pyrite. Clinopyroxene shows a tightly bound, continuous calcium enrichment trend. Olivine phenocrysts show a narrow compositional range from low Ca-pyroxene to pigeonite to subcalcic augite. Maskelynite is usually observed occupying pyroxene and olivine grain boundary pockets. Small vesicles are scattered throughout.
Geochemistry: (M. Spilde, UNM) Olivine Fa40.4±0.9, Fe/Mn=50±2, CaO=0.25±0.05, (wt%), n=6; clinopyroxene Fs26.3±4.6Wo17.6±9.2, Fe/Mn=29±2, n=12; maskelynite An51.0±3.2Ab47.2±3.4Or1.8±0.5, n=7.

Geochemistry: Olivine (Fa31.7-56.6, FeO/MnO = 52-55, N = 5), pigeonite (Fs27.7-48.4Wo10.4-9.8, FeO/MnO = 29-35, N = 3), subcalcic augite (Fs20.7-30.4Wo32.5-34.6, FeO/MnO = 28-32, N = 2), maskelynite (An47.4-50.5Or2.2-1.7, N = 2), alkali feldspar (Ab49.4Or34.0An16.7).
Classification: Shergottite (olivine-phyric).
Specimens: 68.3 g including one polished thin section at UWB; remainder with Mr. S. Bachir/WangZ (12 kg), Mr. M. Lyon (19165 g) and Mr. A. Habibi (3500 g).

Amgala 001 26.014°N, 11.020°W
Saguia el Hamra, Western Sahara
Purchased: 2022 Dec
Classification: Martian meteorite (Shergottite)
History: Multiple stones were found together in December 2022 near Meharrize. Said Muftah Bachir and Ziyao Wang bought 12 kg together from the finders, including the largest 5200 g individual; Mark Lyon acquired 19165 g from two different dealers; Aziz Habibi obtained 3500 g from another dealer.
Physical characteristics: Weathered exterior surfaces of the stones are brown with a distinctive knobby appearance. Fresh interiors are greenish-gray with darker olivine phenocrysts visible.
