Macroscopic Description - Kathleen McBride
The exteriors are covered with a purplish black fusion crust with polygonal fractures and some evaporites. The exposed interior is black. The interiors are a black matrix with evaporites along fractures.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy and Nicole Lunning
These sections are similar enough that one description is sufficient. 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. Olivine compositions are Fa0-2, no pyroxene grains were analyzed. Aqueous alteration of the matrix is substantial. These meteorites are CM1-2 chondrites, possibly paired with the MIL 090986 series reported in the Spring 2012 newsletter.
