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 Fa0-73. Pyroxene analyses range from Fs1-17. These meteorites are CO3 chondrites and are probably members of the MIL 07531 pairing group.
