Northwest Africa 12008 (NWA 12008)
Lunar Meteorite (basalt)
History: Purportedly found in Morocco and purchased by Ben Hoefnagels in August 2018 from a dealer in Zagora, Morocco.
Petrography: (A. Irving and S. Kuehner, UWS) Small olivine phenocrysts (stained orange-brown) are set in an intersertal groundmass composed mainly of zoned clinopyroxene and elongate lath-like maskelynite with accessory skeletal ilmenite, Ti-chromite, Cr-Ti-Fe spinel, troilite and minor barite. Olivine contains inclusions of chromite and quenched melt inclusions (surrounded by radial cracks) composed of Al-Ti-bearing augite + K-bearing glass.
Geochemistry: Olivine (cores Fa36.6-42.3, rim Fa90.0, FeO/MnO = 96-99, N = 3), pigeonite (Fs31.1Wo14.0, FeO/MnO = 50), subcalcic augite (Fs25.9-71.4Wo28.6-23.1, FeO/MnO = 50-75, N = 5), augite (Fs23.2Wo39.7, FeO/MnO = 49), ferropigeonite (Fs80.1Wo19.5, FeO/MnO = 79), augite in melt inclusion (Fs28.8Wo50.1, FeO/MnO = 71, Al2O3 = 10.5 wt.%, TiO2 = 5.3 wt.%), plagioclase (An86.8-87.6Or0.4-0.3, N = 2).
Classification: Lunar (mare basalt).
Specimens: 25.2 g including two polished thin sections at UWB; remainder with Mr. B. Hoefnagels.
I have not studied this one. The composition given in Cohen et al. (2019) is all but indistinguishable from that of NWA 032/479, but the texture is different.
