Writeup

Writeup from MB 111:

Northwest Africa 15365 (NWA 15365)

(Northwest Africa)

Purchased: 2022 Jan

Classification: Ordinary chondrite (L4)

History: Purchased by Wenxi Jin and Ziyao Wang in January 2022 from a dealer in Agadir, Morocco.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Well-formed glass-bearing chondrules are set in a relatively coarse grained matrix containing stained kamacite, taenite, troilite, pentlandite, chlorapatite and merrillite, but no plagioclase.

Geochemistry: Olivine (Fa_24.5±0.4, range Fa_24.1-25.0, N = 5), low-Ca pyroxene (Fs_15.1±5.6Wo_1.6±1.5, range Fs_7.9-20.1Wo_0.4-4.0, N = 5), augite (Fs_8.8±0.1Wo_43.0±1.2, range Fs_8.7-8.9Wo_43.8-42.1, N = 2), plagioclase (Ab_84.8An_11.0Or_4.1). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.88.

Classification: Ordinary chondrite (L4).

Specimens: 21.5 g including one polished thin section at UWB; remainder with Wenxi Jin and WangZ.
