Macroscopic Description - Kathleen McBride
The exterior is a very dark, rusty brown color with vugs and evaporites and has no fusion crust. The interior of this carbonaceous chondrite is very weathered with a brown oxidation rind. The center of the meteorite is less weathered and reveals a black matrix.
Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Rare metal and sulfide occur in the matrix. Olivine ranges in composition from Fa0-40, with a continuous range of intermediate compositions and a slight peak at Fa1-5. One pyroxene analyses shows from Fs2Wo1. The matrix appears to consist largely of Fe-rich olivine. The meteorite is a CO3 chondrite.
