Original Classification CM2 Chondrites
Macroscopic Description - Roger Harrington and Kathleen McBride
The exterior of 07672 has black fusion crust with polygonal fractures and evaporites. Both CM2’s have a black fine grained matrix.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy, Linda Welzenbach and Karen Stockstill
The sections are so similar that a single description suffices. The sections consist of moderately abundant small chondrules (up to 0.5 mm), mineral grains, and CAIs set in a black matrix; rare metal, sulfide and carbonate grains are present. Chondrules are moderately to heavily altered. Olivine compositions are Fa0-19. Aqueous alteration of the matrix is substantial, but the chondrules are only modestly altered. The meteorites are CM2 chondrites.
