Macroscopic Description - Mitchell Haller
All of these carbonaceous chondrites have black fusion crust on exterior surfaces. A few have evaporites. The interiors are a black matrix with gray to white inclusion/chondrules and some oxidation.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy, Pamela Salyer
These sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur both within and rimming the chondrules. Olivine ranges in composition from Fa0-68, with a continuous range of intermediate compositions. Pyroxenes range Fs1-10Wo1-3 with one outlier of Fs46. The matrix appears to consist largely of Fe-rich olivine. These meteorites are CO3 chondrites and are likely paired with the large MIL CO3 pairing group.
