Writeup from MB 99:

Northwest Africa 6358 (NWA 6358)

(Northwest Africa)

Purchased: Oct 2008

Classification: Carbonaceous chondrite (CV3)

Petrography: (M.A. Ivanova, Vernad.) The meteorite consists of fine-grained matrix, chondrules and their fragments, refractory inclusions and isolated grains of minerals. Olivine and pyroxene dominate. The minor phases are plagioclase, spinel, chromite, sulfides, and Fe-Ni metal grains.

Geochemistry: Olivine (EMP) is Fa0.5-10.5. Pyroxene is represented by low-Ca pyroxene Fs1.2Wo0.9En97.9, pigeonite Fs1.1Wo7.5En91.4 and augite Fs2.5Wo38.3En59.2. Oxygen isotopic compositions: (I. A Franchi and R. C Greenwood, OU, by laser fluorination): δ18O = 2.95; 2.02; δ17O = -1.90, -2.73; Δ17O = -3.44, -3.78 per mil.
