Writeup from MB 106:

Northwest Africa 6015 (NWA 6015)

(Northwest Africa)

Purchased: 2009 Oct

Classification: Carbonaceous chondrite (CO3)

Petrography: (K. Metzler, IfP) Chondrules, chondrule fragments, and CAIs are embedded in a fine-grained brownish matrix (about 30 vol% matrix). Most chondrules have apparent diameters between 50 and 250 μm.

Geochemistry: Random measurements of olivine grains revealed Fa23.6±22.2 (Fa1-76); n=21. Random measurements of low-Ca pyroxene grains revealed Fs2.3±1.3Wo0.6±0.4 (Fs1-6Wo0-2); n=20.

Classification: CO chondrite based on CAI occurrence, small chondrule size, chondrule-matrix ratio, and mineral chemistry. Petrologic type 3 based on the chemical variability of olivine and pyroxene.
