Rabt Sbayta 002 24.241°N, 14.701°W Rio de Oro, Western Sahara Find: 2016-Aug Classification: Lunar meteorite (feldspathic breccia) History: Found by Mbarek Laghfiri and Mohamed Chikh Boy near Gataa Sfar in August 2016 and shortly thereafter. Purchased by Darryl Pitt from a Morrocan dealer in Agadir. Physical characteristics: A single large stone (6371.9 g) lacking fusion crust but with a thin desert patina on exterior surfaces. The fresh interior exhibits pale gray to whitish clasts set in a dark gray, fine grained matrix. Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular minerals clasts of anorthite, orthopyroxene, olivine, pigeonite, exsolved pigeonite, ilmenite, chromite, fayalite and Ti-chromite in a fine grained, partly vesicular matrix of the same minerals plus troilite and minor barite. Rare quench-textured lithic clasts are present. Geochemistry: Olivine (Fa23.4, FeO/MnO = 64; Fa43.9, FeO/MnO = 100), orthopyroxene (Fs58.6-60.4Wo2.4-1.9, FeO/MnO = 57-72, N = 2), pigeonite (Fs44.6Wo7.9, FeO/MnO = 54; Fs27.8Wo21.3, FeO/MnO = 47), augite host in exsolved pigeonite (Fs20.9Wo38.4, FeO/MnO = 54), fayalite (Fa78.1, FeO/MnO = 81), plagioclase (An96.5-97.2Or0.2, N = 2). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 3.5, Na2O 0.37; (in ppm) Sc 7.2, Ni 90, La 1.1, Sm 0.57, Eu 0.82, Yb 0.50, Lu 0.07, Hf 0.35, Th 0.14. Magnetic susceptibility log χ (× 10-9 m3/kg) = 2.49. Classification: Lunar (feldspathic breccia). Specimens: 22.9 g in the form of a single polished slice at UWB; remainder with DPitt. | ||||||||||||||||||||||||||||||||||||||
