Meteorite (feldspathic breccia)
group of similar stones were found together at an undisclosed location in
southern Morocco during 2015.
characteristics: Several grayish brown stones
(total weight 15.6 kg) lacking fusion crust, but with a polished external
appearance. All exhibit the same overall fine grained texture, with some
visible larger whitish clasts within a dark gray matrix.
(A. Irving and S. Kuehner, UWS)
Relatively fine grained fragmental breccia composed of mineral clasts of
anorthite, pigeonite, olivine, augite, Ti-chromite and troilite set in a
matrix containing minor secondary barite.
(Fa34.8-42.3, FeO/MnO = 86-95, N = 4), pigeonite (Fs29.8-32.4Wo8.8-12.9,
FeO/MnO = 47-52, N = 3), augite (Fs20.6Wo35.4,
FeO/MnO = 49), plagioclase (An96.4-97.1Or0.1, N = 2).
Bulk composition (R. Korotev, WUSL)
INAA of subsamples gave the following mean abundances: (in wt.%) FeO 7.0,
Na2O 0.30; (in ppm) Sc 17.0, La 1.9, Sm 1.0, Eu 0.67, Yb 1.0, Lu
0.15, Hf 0.6, Th 0.15.
Lunar (feldspathic breccia).
24.3 g including one stone polished on one side at UWB; the remaining material is held by the anonymous finders.
