Original Classification CO3 Chondrite
Macroscopic Description - Roger Harrington, Kathleen McBride, and Cecilia Satterwhite
All of these carbonaceous chondrites possess dull, black fusion crust with surface areas ranging from 10 to 100%. The matrices of these meteorites are fine grained and range in color from dark gray to brown to black. Inclusions are visible in most of them and vary in color from white to gray.
Thin Section (,2) Description - 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 exist, as well. Olivine ranges in composition from Fa0-80. Pyroxene analyses range from Fs0-44 (most from Fs0-13). These meteorites are somewhat terrestrially altered CO3 chondrites (likely type 3.0-3.2) and are probably members of the MIL 07182 pairing group.
