Writeup from MB 105:

Northwest Africa 10777 (NWA 10777)

Morocco

Purchased: 2002

Classification: Carbonaceous chondrite (CV3)

History: The meteorite was bought in 2002 in Sainte-Marie-aux-Mines, France, from a Moroccan dealer.

Physical characteristics: A single partially crusted dark stone. Cut surface reveals large chondrules (to several mm) and CAIs (to 5 mm) set in an abundant dark matrix.

Petrography: Chondrules (mostly type I, average apparent diameter 1060±590 μm, N=30) and CAIs set in a fine-grained iron-rich matrix (about 50 vol%). The matrix has a macroscopic foliation. Opaques are sulfides and magnetite. Rare metal.

Geochemistry: Chondrule olivine Fa2.3±2.1, PMD 46%, range Fa0.8-8.3, N=12. Cr2O3 in ferroan olivine 0.38±0.10 wt.% (N=5). Magnetic susceptibility log χ (× 10-9 m3/kg) = 4.40.

Classification: Carbonaceous chondrite (CV3, oxidized subgroup).

Specimens: 2.4 g and a polished section at CEREGE. Main mass with N. Tourment.
