Writeup from MB 104:

Northwest Africa 10130 (NWA 10130)

(Northwest Africa)

Purchased: 2015 Feb

Classification: Lunar meteorite (feldspathic breccia)

History: Purchased by Darryl Pitt in February 2015 from a Moroccan dealer at the Tucson Gem and Mineral Show.

Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed mainly of mineral clasts of anorthite, olivine, pigeonite (some exsolved), subcalcic augite, augite, ilmenite and troilite set within a finer grained, in part vesicular matrix containing sparse Ni-poor kamacite. A fine grained mare basalt clast was observed, as well as some cross-cutting glassy veinlets.

Geochemistry: Olivine (Fa23.3-24.1, FeO/MnO = 94-108, N = 3), pigeonite (Fs19.6-20.2Wo6.5-6.7, FeO/MnO = 49-61, N = 2), subcalcic augite (Fs11.9Wo33.5, FeO/MnO = 39), augite (Fs12.2Wo39.1, FeO/MnO = 63). Plagioclase >An95 by EDS analysis. Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 6.3, Na2O 0.63; (in ppm) Sc 9.9, Ni 670, La 16.3, Sm 7.3, Eu 1.33, Yb 5.1, Lu 0.70, Th 2.5.

Classification: Lunar (feldspathic breccia). Paired with NWA 8455 based on textural, mineralogical and bulk compositional similarities.

Specimens: 20.1 g including one polished endcut at UWB. The remainder is held by DPitt.
