Writeup from MB 107:

Northwest Africa 12367 (NWA 12367)

(Northwest Africa)

Purchased: April 2018

Classification: Carbonaceous chondrite (CO3)

History: Bought in April 2018 from a dealer in Zagora, Morocco.

Petrography: (A. Bischoff, IfP) Chondrules, chondrule fragments, and CAIs are embedded in a fine-grained brownish matrix, which has an abundance of about 20-30 vol%. The majority of chondrules belong to chemical type I and the mean apparent chondrule size is about 200 µm.

Geochemistry: (K. Klemm; A. Bischoff, IfP) Mineral compositions and geochemistry: Random measurements of olivine grains revealed Fa10.3±14.5 (Fa0.7-43.3); n=29. Random measurements of low-Ca pyroxene grains revealed Fs6.2±12.0Wo1.5±1.0 (Fs0.6-35.9Wo0.5-4.3); n=15.

Classification: CO3 chondrite based on small chondrule size, chondrule-matrix ratio, texture, and mineral chemistry.
