Writeup from MB 104:

Northwest Africa 10091 (NWA 10091)

Morocco

Purchased: Feb 2013

Classification: Carbonaceous chondrite (CV3)

Physical characteristics: The stone is roughly spherical, with many chondrules visible on its surface. The stone is heavily weathered, with abundant matrix clays.

Petrography: (A.E. Rubin, UCLA) One fluffy type-A, fine-grained CAI fragment measuring 70 × 150 μm in the thin section. Average chondrule diameter ~800 μm, many with igneous rims. Matrix abundance is ~40%, indicative of CV chondrites. Heterogeneity of olivine indicates type 3. Most chondrules are type I porphyritic or barred olivine, characteristic of CV3. Some metal and sulfide is still preserved within chondrules.
