Mineral Composition (%Fa &  %Fs)
Fayalite (mol%): 1-56
Macroscopic Description - Roger Harrington, Kathleen McBride and Cecilia Satterwhite
These carbonaceous chondrites have black/brown fusion crust; some have evaporites. Areas without fusion crust range from dark gray to black with some rusty brown matrix. The interiors are fine grained black matrix with minor oxidation and contain some tiny white inclusions.
Thin Section Description (,2) - Cari Corrigan and Nicole Lunning
These meteorites are so similar that a single description suffices. The sections consist of abundant small (up to 1.3 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 are dark inclusions (specifically in MIL 090470). Olivine ranges in composition from Fa0-76. Pyroxene analyses range from Fs1-15 Wo0-5 with one Fs35. 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 07531 pairing group.
