Name: Miller Range 07626 This is an OFFICIAL meteorite name. Abbreviation: MIL 07626 Observed fall: No Year found: 2007 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 7.2 g
Macroscopic Description - Roger Harrington, Kathleen McBride and Cecilia Satterwhite
These carbonaceous chondrites have varying amounts (20-100%) of brown/black fusion crust with oxidation haloes and rusty areas. Some exterior surfaces are pitted. The interiors of these meteorites range in color from brown to dark gray to black. Most have a fine-grained matrix with light colored inclusions.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
These sections are so similar that a single description suffices. The sections consist of abundant (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. They are CO3 chondrites (likely type 3.0-3.2) and are probably members of the MIL 07099 pairing group.
