Writeup from MB 104:

Northwest Africa 10082 (NWA 10082)

(Northwest Africa)

Purchased: 2014 Aug

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Alexandre Debienne in August 2014 from a dealer in Agadir, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Very fine grained annealed breccia with granoblastic texture. Minerals are anorthite, olivine, pigeonite, pentlandite, pleonaste and troilite, with minor fayalite and kamacite.

Geochemistry: Olivine (Fa29.2-31.4, FeO/MnO = 103-129, N = 3), pigeonite (Fs21.7-23.0Wo17.2-11.8, FeO/MnO = 55-56, N = 3). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 3.5, Na2O 0.46; (in ppm) Sc 5.1, Ni 490, La 2.8, Sm 0.73, Eu 0.96, Yb 1.1, Lu 0.15, Hf 1.0, Th 0.72.

Classification: Lunar (feldspathic granulitic breccia). Paired with NWA 8022 based on distinctive texture and bulk composition.

Specimens: 1.28 g including a polished piece at PSF; main mass with Mr. A. Debienne.
