Macroscopic Description - Kathleen McBride, and Cecilia Satterwhite
The exteriors of these carbonaceous chondrites have brown/black fusion crust with polygonal fractures. The interiors range from dark gray to black fine grained matrix with minor oxidation and small white inclusions.
Thin Section Description (,MIL 090705,3; MIL 090890,4; MIL 090891,4) - Cari Corrigan 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. Glass within chondrules appears to be very clear/fresh. CAIs are abundant in many sections (mostly Type A), and range in size up to 1 mm, many containing blue hibonite grains. At least one compound CAI was found. AOAs up to 1 mm are present, as well. Olivine ranges in composition from Fa0-71. Pyroxene analyses range from Fs1-10 Wo0.9 with one Wo35. These meteorites vary with respect to terrestrial alteration. These meteorites are CO3 chondrites (likely type 3.0-3.2) and are probably members of the MIL 07099 pairing group.
