Northwest Africa 10665 (NWA 10665)

(Northwest Africa)

Purchased: 2016 Mar

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Fabien Kuntz in March 2016 from a dealer in Zagora, Morocco.

Physical characteristics: A single dark stone (24.73 g) lacking fusion crust. The fresh interior contains ~30 vol% of white and beige clasts in a fine-grained black matrix.

Petrography: (A. Irving and S. Kuehner, UWS) Relatively fine-grained breccia composed of mineral fragments (anorthite, pigeonite, exsolved pigeonite, olivine, augite, chromite, ilmenite, troilite, kamacite) plus some glass fragments in a finer grained matrix.

Geochemistry: Olivine (Fa7.3; Fa26.7; Fa 38.2; FeO/MnO = 74-87, N = 3), orthopyroxene host in exsolved pigeonite (Fs34.3Wo3.2, FeO/MnO = 48), pigeonite (Fs33.0Wo7.2, FeO/MnO = 49), augite (Fs16.3-18.0Wo35.1-37.8; Fs11.0Wo42.3; FeO/MnO = 36-42, N = 3), plagioclase (An96.7-97.3Or0.1, N = 2).

Classification: Lunar (feldspathic breccia).

Specimens: 5.01 g in the form of one polished endcut at PSF; remainder with Kuntz.
