Macroscopic Description - Kathleen McBride
Brown/black fusion crust on these meteorites range from 50-100%. Oxidation and fractures are present. The interiors are fine grained black matrix with white/weathered inclusions/chondrules.
Thin Section (,4) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
These meteorites are so similar that a single description suffices. The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa0-51. Two pyroxene analyses range from Fs1-11. The meteorites are CO3 chondrites.
