The Meteoritical Bulletin, No.
Purchased: 2016 February
Mass: 49.15 g
meteorite (feldspathic breccia)
History: Purchased by
Gary Fujihara in February 2016 from a dealer in Ouarzazate, Morocco.
Physical characteristics: A single
stone (49.15 g) lacking fusion crust. Interior slices exhibit separated
white clasts and rare small metal grains set in a black matrix (~60 vol.%).
Petrography: (A. Irving
and S. Kuehner, UWS) Olivine-poor
feldspathic breccia composed of angular mineral grains in a finer matrix.
Minerals are anorthite, orthopyroxene, pigeonite, augite, rare olivine,
ilmenite, Ti-chromite, troilite, taenite and zirconolite.
Carpenter, WUSL; S. Kuehner, UWS) Orthopyroxene (Fs39.9Wo4.8,
FeO/MnO = 54), pigeonite (Fs31.8Wo14.7, FeO/MnO =
49), subcalcic augite (Fs21.2Wo33.9, FeO/MnO = 44),
low-Ca pyroxene host (Fs43.8Wo10.8, FeO/MnO = 67),
clinopyroxene exsolution lamella (Fs28.4Wo33.9,
FeO/MnO = 57), anorthite (AnOr0.1, N = 4), olivine (Fa24.8-47.7,
FeO/MnO = 83-97, N = 4). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave (in wt.%) FeO 3.8, Na2O 0.39; (in
ppm) Sc 7.2, Cr 490, Co 13, La 6.2, Sm 2.8, Eu 0.91, Yb 1.8, Lu 0.25, Hf
2.0, Th 0.9.
