Macroscopic Description - Kathleen McBride
The exterior is covered with brown/black shiny fusion crust with pits, evaporites and oxidation haloes. The interiors consist of a gray and black matrix with tiny light inclusions.
Thin Section (,3) Description - Tim McCoy, Linda Welzenbach, Cari Corrigan, and Rhiannon Mayne
These sections 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 Fa_1-62, with a continuous range of intermediate compositions and a slight peak at Fa_20-40. Two pyroxene analyses range from Fs_1-8Wo_2-4. The meteorites are CO3 chondrites.
