Northwest Africa 1292 (NWA 1292)

(Northwest Africa)

Purchased: Aug 2001

Classification: Carbonaceous chondrite (CO3)

History: Purchased by G. and A. Hupe in August 2001 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Fairly closely-packed, well-formed small chondrules (apparent diameter 190±100 µm) together with mineral fragments and fine grained CAI are set in a sparse matrix (~15 vol.%) containing stained kamacite and minor pleonaste.

Geochemistry: Olivine (Fa0.5-39.9, Cr2O3 in ferroan examples 0.06-0.76 wt.%, mean 0.19±0.28 wt.%, N = 7), orthopyroxene (Fs1.4Wo2.9), pigeonite (Fs6.5Wo5.7), clinopyroxene (Fs0.5-9.4Wo49.3-49.0, N = 2).

Classification: Carbonaceous chondrite (CO3).

Specimens: 21.7 g including one polished thin section at PSF; 11.3 g at UCLA; remainder with GHupé.
