Writeup from MB 103:

Northwest Africa 7302 (NWA 7302)

Morocco

Found: 2009

Classification: Carbonaceous chondrite (CK5)

Petrography: Largely recrystallized matrix dominated by olivine and feldspar. Chondrules are poorly defined and chemically equilibrated with the host matrix. CAIs are visible to the naked eye and some of them have sizes up to few millimeters. Olivine grains in matrix contain porosity and inclusions of opaque minerals (Cr-bearing magnetite and Ni-rich sulfides).

Geochemistry: Olivine (Fa34.1±0.3, NiO up to 0.40 wt%), Ca-poor pyroxene (Fs27.5±1.3Wo0.7±0.3), Ca-rich pyroxene (Fs13.2±0.1Wo47.3±0.2)
