Writeup from MB 105:

Northwest Africa 10588 (NWA 10588)

Morocco

Purchased: 2015

Classification: Carbonaceous chondrite (CK3)

Petrography: The rock has a strong petrofabric; chondrules are significantly fractured. Many chondrules have igneous rims; the average chondrule diameter is ~900 μm. Broken amoeboid olivine inclusions are present. Also present is a CAI composed of olivine, diopside and anorthite that may be a melted AOI. Unlike typical CK chondrites, the matrix of the meteorite is opaque (as in CV3 chondrites); unlike most CV chondrites, the mean olivine Fa content is very high. The matrix constitutes 35-40 vol.% of the rock. Low-Ca pyroxene exhibits polysynthetic twinning. Olivine grains exhibit weak mosaic extinction. Limonite patches and veins are present. There are also small sulfide grains and a few magnetite grains 10-20 μm in size.

Geochemistry: This rock seems to be intermediate between normal CV3 chondrites and typical CK4 chondrites. CK3 is the best classification.
