Macroscopic Description - Mitchell Haller, Charis Krysher, Kathleen McBride, Cecilia Satterwhite
The exteriors of these CO3’s have brown/black fusion crust, some fractured with evaporites and rusty areas. The interiors range from rusty brown to black matrices with tiny white specks, some have rusty inclusions/chondrules. The textures range from fine to coarse 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. Metals and sulfides occur both within and rimming the chondrules. Olivine ranges in composition from Fa0-64, with a continuous range of intermediate compositions. Pyroxenes range from Fs1-15Wo1-3. The matrix appears to consist largely of Fe-rich olivine. These meteorites are CO3 chondrites and are likely paired with the MIL 07099 pairing group.
