Writeup from MB 108:

Northwest Africa 12514 (NWA 12514)

(Northwest Africa)

Purchased: 2005

Classification: Ordinary chondrite (L3)

History: Purchased by an anonymous collector from a dealer at the Munich Show in 2005, subsequently acquired by the Hollis Collection and then donated to PSF.

Petrography: (A. Irving and S. Kuehner, UWS) Well-formed chondrules (apparent diameter 800±260 µm, N = 22) are set in a finer matrix containing stained metal, merrillite and chlorapatite. A few small type 6 clasts were observed in the studied thin section.

Geochemistry: Olivine (Fa13.8-28.3, average Fa23.3±4.6, Cr2O3 in ferroan examples 0.03-0.11 wt.%, mean 0.06±0.03 wt.%, N = 7), orthopyroxene (Fs4.6-17.8Wo0.2-1.3, average Fs12.1±6.8Wo0.7±0.6, N = 3), clinopyroxene (Fs6.7-7.1Wo42.2-45.6, N = 2). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.81.

Classification: Ordinary chondrite (L3).

Specimens: The entire specimen including one polished thin section is at PSF.
