Writeup from MB 106:

Northwest Africa 11232 (NWA 11232)

(Northwest Africa)

Purchased: 2016 Nov

Classification: Ordinary chondrite (L(LL)3)

History: Purchased by Fabien Kuntz in November 2016 from a dealer in Nouakchott, Mauritania.

Petrography: (A. Irving and S. Kuehner, UWS) Closely packed, well-formed chondrules (apparent diameter 500±300 μm) are set in a sparse, fine-grained matrix containing merrillite and chlorapatite.

Geochemistry: Olivine (Fa_0.5-30.2, Cr₂O₃ in ferroan examples < 0.5 wt.%, N = 7), orthopyroxene (Fs_1.0-51.8Wo_0.4-1.4, N = 3), subcalcic augite (Fs_18.8Wo_30.6), augite (Fs_10.9Wo_37.0). Magnetic susceptibility log χ (× 10^-9 m³/kg) = 4.50.

Classification: Ordinary chondrite (L(LL)3).

Specimens: 24.9 g including one polished thin section at PSF; remainder with Mr. F. Kuntz.
