Macroscopic Description - Kathleen McBride
~90% of the exterior surface is covered with thick brown/black fusion crust with polygonal fractures. The interiors are composed of gray matrix with large chondrules and are very hard.
Thin Section Description (,3, 4) - Tim McCoy
These meteorites are so similar that a single description suffices. The sections consist of large (up to 2 mm) chondrules and isolated mineral grains in a matrix of finer-grained silicates, sulfides and very abundant magnetite. Olivine is Fa29-32 and calcic pyroxene is Fs10Wo45. The meteorites are CK4 chondrites.
