| Macroscopic Description - Mitchell Haller, Kathleen McBride, Cecilia Satterwhite | |
| The exteriors of these carbonaceous chondrites have black/brown fusion crust with oxidation haloes and rusty areas. The interiors range from dark gray to black matrix with some oxidation and tiny white specks. Most are fine grained. | |
| Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach, Pamela Salyer | |
| These sections consist of abundant, small (up to 1 mm) chondrules, chondrule fragments, and mineral grains in a dark matrix. The matrix appears to consist largely of Fe-rich olivine. Metals and sulfides occur both within and rimming the chondrules. These meteorites have distinctly less metals and sulfides than the larger CO3 pairing group (MIL 07099). Olivine ranges in composition from Fa0-61, with a continuous range of intermediate compositions. Pyroxenes range Fs0-9Wo1-3. These meteorites are CO3 chondrites and are likely paired. | |
