Northwest Africa 12384 (NWA 12384)

(Northwest Africa)

Purchased: 2018 Nov

Classification: Lunar meteorite (basaltic breccia)

History: Purchased in Agadir, Morocco, in November 2018 by Aziz Habibi.

Physical characteristics: Two dense stones (total 244 g) coated by a thin, dark brown patina, but exhibiting a very fresh, gray interior with some visible basaltic clasts.

Petrography: (P. Carpenter, WUSL and A. Irving, UWS) The specimen is a breccia consisting of rounded mare basalt clasts with intersertal texture set in a matrix of related crystalline debris. Major mineral phases are olivine, pigeonite (some zoned to ferropigeonite) and anorthite with accessory ilmenite, merrillite, fluorapatite, troilite, zirconolite, tranquillityite and FeNi metal. The basalt clasts also contain K-rich mesostasis. A fine grained vesicular shock vein crosscuts the studied sample.

Geochemistry: Olivine in breccia matrix (Fa30.0-50.4, FeO/MnO = 93-113, N = 6), pigeonite in breccia matrix (Fs30.6-31.8Wo10.4-22.7, FeO/MnO = 54-58, N = 2), pigeonite in basalt clast (cores Fs28.9-29.4Wo7.9-8.4, FeO/MnO = 50-56, N = 3; rims Fs44.8-79.6Wo16.3-20.4, FeO/MnO = 59-88, N = 3), subcalcic augite in breccia matrix (Fs24.6Wo31.5, FeO/MnO = 59), plagioclase in breccia matrix (An81.1-95.6Or1.1-0.1, N = 2), plagioclase in basalt clast (An82.3-89.7Or0.7-0.4, N = 4).

Classification: Lunar (mare basalt breccia).

Specimens: 22.3 g including one polished endcut and one polished thin section at UWB; remainder with Luc Labenne.
