Writeup from MB 104:

Northwest Africa 10077 (NWA 10077)

(Northwest Africa)

Purchased: 2014 Jul

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Fabien Kuntz in July 2014 from a dealer in Foum El Hisn, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of angular mineral fragments in a finer grained matrix containing vsicles. Minerals are anorthite, olivine, orthopyroxene, pigeonite, silica polymorph, bytownite, Cl-bearing apatite, ilmenite, troilite and kamacite.

Geochemistry: Olivine (Fa23.9-32.0, FeO/MnO = 84-94, N = 3), orthoproxene (Fs26.6Wo3.5, FeO/MnO = 68, N = 1), pigeonite (Fs21.3-23.6Wo17.4-10.9, FeO/MnO = 53-63, N = 3), plagioclase (An95.3-96.5Or0.4; An83.2Or0.8; N = 3). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 5.2, Na2O 0.48; (in ppm) Sc 10.2, La 5.9, Sm 2.7, Eu 1.11, Yb 1.83, Lu 0.25, Th 0.9.

Classification: Lunar (feldspathic regolithic breccia). Paired with NWA 8641 based on texture and bulk composition.

Specimens: 1.08 g piece polished on one side at PSF; main mass with Kuntz.
