Writeup from MB 104:

Northwest Africa 10101 (NWA 10101)

(Northwest Africa)

Purchased: 2013 Sep 5

Classification: Carbonaceous chondrite (CV3)

Petrography: (A.E. Rubin, UCLA) Meteorite contains ~45% matrix, with an average chondrule diameter of ~800 μm. The largest CAI in the examined section is an elongate, fluffy type-A CAI, interwoven with fine-grained matrix: it measures 1.7 × 0.5 mm. Other, fine-grained, fluffy type-A CAIs in the section measure 900 × 250 μm & 200 × 150 μm. Several ~1 mm AOIs are present in the section, as well as many type I porphyritic chondrules with igneous rims. Many chondrules contain polysynthetically twinned low-Ca pyroxene, indicative of a type 3 chondrite. Chondrules are very sharply defined. The stone contains secondary magnetite. Some metal has been converted into oxides, but the matrix is not thoroughly stained.
