Macroscopic Description - Kathleen McBride
The exterior has no fusion crust and is a dull brown/black rusty surface. The interior is grayish brown with lighter oxidation rind.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
The section consists of a few chondrules (up to 1 mm) that have been completely replaced by phyllosilicate set in an Fe-rich serpentine matrix. No isolated mineral grains or CAIs are apparent; sulfide and carbonate grains are present. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found. This meteorite is a CM1 chondrite.
