Writeup from MB 103:
Northwest Africa 8577 (NWA 8577) Morocco Purchased: May 2014 Classification: CV3-ox Petrography: Ferroan olivine contains 0.09±0.09 wt.% Cr2O3; the meteorite contains abundant fine-grained matrix, about 35 vol.%, consistent with a CV chondrite. It has large chondrules, averaging about 800 μm in diameter, again consistent with CV. Many of the chondrules have igneous rims. Porphyritic and barred olivine chondrules are abundant; RP and C chondrules were not identified (again consistent with a CV classification). Amoeboid olivine inclusions are moderately abundant; several reach 1 mm in maximum dimension. Opaque phases consist of moderately abundant magnetite and sulfide and little metallic Fe-Ni; this indicates that the rock is an oxidized CV chondrite. The meteorite contains a few percent of refractory inclusions; these include several fine-grained inclusions as well as some small CAI fragments in the matrix. | ||||||||||||||||||||||||||||||
