Macroscopic Description - Kathleen McBride and Cecilia Satterwhite
The exteriors of these carbonaceous chondrites have rough black fusion crust with some polygonal fractures and evaporites. The interior matrices are dark gray to black in color with light colored, tiny inclusions, as well as some evaporites and minor oxidation.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy and Nicole Lunning
These meteorites are similar enough that one description suffices. The sections consist of a few small chondrules (up to 0.5 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivines are unequilibrated with compositions of Fa0-44. Pyroxene compositions are Fs5-12, though adequate pyroxene grains were not found in every sample. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorites are CM2 chondrites.
