Writeup from MB 104:

Northwest Africa 10055 (NWA 10055)

Morocco

Purchased: 2014

Classification: Carbonaceous chondrite (CV3)

Petrography: The rock contains abundant fine-grained matrix. There are some fine-grained CAIs and some round, coarser CAIs. The chondrules are of POP and BO types and have a mean size of ~900 µm. The sample is extremely weathered; about 95% of the opaque phases have been altered and there is minor alteration of the silicates. Unrimmed amoeboid olivine inclusions are present. There are no large metal grains (as is common in CR chondrites). Metallic Fe-Ni is rare; the rock does not exhibit a petrofabric. It is an oxidized CV, probably of the Allende subgroup.
