Writeup from MB 104:
Northwest Africa 10065 (NWA 10065) (Northwest Africa) Purchased: 2014 Jun Classification: Lunar meteorite (feldspathic breccia) History: Purchased by Darryl Pitt in June 2014 from a dealer in Mauritania. Physical characteristics: Single stone (282.8 g) coated by orange-brown weathering products. The fresh interior is dark gray with white clasts and visible fresh metal grains. Petrography: (A. Irving and S. Kuehner, UWS) Breccia composed of mineral clasts of anorthite, pigeonite (some exsolved), olivine, orthopyroxene, subcalcic augite, augite, ferropigeonite, Ti-Cr-bearing spinel, kamacite, troilite and rare silica polymorph, together with rare devitrified glass spheres (of anorthite+pyroxene bulk composition), in a finer grained matrix containing sparse vesicles. Geochemistry: Olivine (Fa26.4-58.6, FeO/MnO = 94-100, N = 3), orthopyroxene (Fs11.4-19.2Wo3.7-3.5, FeO/MnO = 87-68, N = 2), pigeonite (Fs32.6Wo8.2, FeO/MnO = 65), ferropigeonite (Fs45.5-64.8Wo20.4-22.6, FeO/MnO = 65-73, N = 2), subcalcic augite (Fs22.1Wo35.8, FeO/MnO = 58), augite (Fs13.0-13.9Wo38.5-41.9, FeO/MnO = 51-56, N = 2), plagioclase (An95.4-96.3Or0.2, N = 2). Bulk composition (R. Korotev, WUSL) INAA of subsamples gave the following mean abundances (in wt.%) FeO 7.9, Na2O 0.32; (in ppm) Sc 17.4, Ni 490, La 5.1, Sm 2.29, Eu 0.73, Yb 2.0, Lu 0.28, Hf 1.7, Th 1.1. Classification: Lunar (feldspathic regolithic breccia). Bulk abundances for many elements overlap with those for NWA 8746, suggesting pairing of these two stones. Specimens: 21.4 g including one polished endcut at UWB. The remainder is held by DPitt. | ||||||||||||||||||||||||||||||
