End cut of Lunar feldspatic breccia Rabt Sbayta - 43×39×6 mm - 12.1 g - (1)

Rabt Sbayta 24.241°N, 14.701°W

Rio de Oro, Western Sahara

Classification: Lunar meteorite (feldspathic breccia)

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).
