Northwest Africa 8126 (NWA 8126)

(Northwest Africa)

Purchased: 2013 Feb

Classification: Carbonaceous chondrite (CO3)

History: Purchased by S. Vasiliev and M. Jost in February 2013 from a dealer in Erfoud, Morocco.

Petrography: (A. Irving and S. Kuehner, UWS) Small chondrules, mineral fragments and CAI are present in a dark brown, anhydrous matrix. Minerals are olivine, orthopyroxene, pigeonite, subcalcic augite, troilite and rare taenite. One small aggregate of djerfisherite grains was found.

Geochemistry: Olivine (Fa0.9-57.3; Cr2O3 in ferroan examples is 0.19-0.43 wt.%, mean 0.30 wt.%, s.d. 0.10 wt.%, N = 9), orthopyroxene (Fs1.1-15.7Wo0.9-3.2, N = 3), pigeonite (Fs15.9Wo10.3), subcalcic augite (Fs0.9-25.3Wo39.9-36.8).
