Rabt Sbayta 003 24.122°N, 14.772°W Rio de Oro, Western Sahara Find: 2016 Nov Classification: Martian meteorite History: Found in the same area as NWA 7034 and paired stones in November 2016, and shortly thereafter purchased by Ben Hoefnagels from a dealer in Taliouine, Morocco. Physical characteristics: A single black, roughly equidimensional stone (20.57 g) with a glossy exterior and some areas of degraded fusion crust with remnant expansion cracks. Small whitish to yellowish-green clasts are visible within a black, fine grained matrix. Petrography: (A. Irving and S. Kuehner, UWS) Polymict breccia composed mainly of various angular mineral clasts plus rare polymineralic clasts in a finer grained matrix. Mineral clasts include orthopyroxene, labradorite, ilmenite, Ti-bearing magnetite, ulvöspinel, altered pyrite, Na-K feldspar, chlorapatite and rare zircon. Geochemistry: Orthopyroxene (Fs19.6-46.7Wo3.1-4.6, FeO/MnO = 32-41, N = 3), subcalcic augite (Fs27.3-32.6Wo40.4-36.9, FeO/MnO = 15-33, N = 2), plagioclase (An35.3-45.2Or2.8-2.1, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.48. Classification: Martian (polymict regolith breccia). Paired with NWA 7034, NWA 7475, NWA 7533, NWA 10922 and others from the same area. Specimens: 4.2 g including one polished thin section at UWB; main polished endcut mass with Mr. B. Hoefnagels. | ||||||||||||||||||||||||||||||||||||
