Writeup from MB 111:

Northwest Africa 15002 (NWA 15002)

(Northwest Africa)

Purchased: 2022 Jan

Classification: Ordinary chondrite (L3)

History: Purchased by Marcin Cimala in January 2022 from a Moroccan dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Well-formed, closely-packed unequilibrated chondrules (apparent diameter 940±520 µm, N = 25) containing devitrified glass are set in a fine grained matrix containing stained kamacite, troilite and rare chromite.

Geochemistry: Olivine (Fa_25.1±23.4, range Fa_8.0-98.7, N = 13; Cr₂O₃ in ferroan olivine 0.01-0.18 wt.%, mean 0.11±0.06 wt.%, N = 14), low-Ca pyroxene (Fs_18.5±12.2Wo_1.0±0.7, range Fs_2.9-27.3Wo_0.2-2.0, N = 4), pigeonite (Fs_22.6Wo_14.3). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.48.

Classification: Ordinary chondrite (L3).

Specimens: 40.0 g including one polished thin section at UWB; remainder with Mr. M. Cimala.
