Northwest Africa 15052 (NWA 15052) (Northwest Africa) Purchased: 2022 May Classification: Lunar meteorite (basaltic breccia) History: Purchased by Terry Boudreaux in May 2022 from a dealer in Zagora, Morocco. Physical characteristics: A single, very dark gray stone (202 g) lacking fusion crust. The fresh interior contains small gray to white clasts in a dark gray matrix. Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Breccia composed predominantly of crystalline debris and intact lithic clasts from mare basalt lithologies. Some lithic clasts contain acicular plagioclase and several have glass present, and at least one ilmenite-bearing pigeonite basalt clast was observed. Minerals include olivine, calcic plagioclase, pigeonite, ferropigeonite, subcalcic augite, ilmenite, troilite, zircon, REE-bearing merrillite, baddeleyite, Ti-chromite and rare kamacite. Glass fragments (some K-bearing) as well as symplectitic intergrowths of fayalite+ferroaugite+silica polymorph are also present. Geochemistry: Olivine (Fa31.3-99.7, FeO/MnO = 94-110, N = 7), pigeonite (Fs39.8Wo7.7; Fs27.6Wo20.1; FeO/MnO = 56-64; N = 2), ferropigeonite (Fs71.0-79.6Wo14.6-13.8, FeO/MnO = 62-71, N = 2), subcalcic augite (Fs26.6Wo29.6; Fs39.8Wo27.8; FeO/MnO = 51-66; N = 2), ferroaugite (Fs56.7Wo39.5, FeO/MnO = 79), plagioclase (An83.8-91.4Or1.8-0.2, N = 4). Classification: Lunar (basaltic breccia). Specimens: 20.l g including a polished endcut at UWB; remainder with Mr. T. Boudreaux. | ||||||||||||||||||||||||||||||
