Northwest Africa 10678

(Northwestern Africa)
Purchased: 2016 February
Mass: 49.15 g

Classification: Lunar 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.

Geochemistry: (P. 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 (An­95.0-98.2Or0.1, 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.

Classification: Lunar (feldspathic breccia).

Specimens: 9.85 g including one slice and a polished mount at UWB; remainder with Mr. G. Fujihara.


Randy Says…

I think this one is unique.
