Northwest Africa 10649 (NWA 10649)

(Northwest Africa)

Purchased: 2015 Dec

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Fabien Kuntz in December 2015 from a dealer in Zagora, Morocco.

Physical characteristics: A single dark gray, uncrusted stone (41.3 g) with visible whitish clasts.

Petrography: (A. Irving and S. Kuehner, UWS) Fragmental breccia composed of mineral clasts of anorthite, olivine, pigeonite, diopside, exsolved pigeonite, troilite, kamacite, taenite, ilmenite, fayalite and chromite in a finer matrix of the same minerals.

Geochemistry: Olivine (Fa25.0-33.7; Fa82.9; FeO/MnO = 82-87, N = 3), pigeonite (Fs45.8Wo6.8, FeO/MnO = 58), diopside (Fs7.6Wo44.9, FeO/MnO = 24, Cr2O3 = 0.8 wt.%), orthopyroxene host (Fs42.4Wo3.8, FeO/MnO = 50), clinopyroxene lamella (Fs19.4Wo40.9, FeO/MnO = 39), plagioclase (An96.3-96.5Or0.1, N = 2).

Classification: Lunar (feldspathic breccia).
