Northwest Africa 11232 (NWA 11232)

(Northwest Africa)

Purchased: 2016 Nov

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 (Fa0.5-30.2, Cr2O3 in ferroan examples < 0.5 wt.%, N = 7), orthopyroxene (Fs1.0-51.8Wo0.4-1.4, N = 3), subcalcic augite (Fs18.8Wo30.6), augite (Fs10.9Wo37.0). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.50.

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