Macroscopic Description - Kathleen McBride
50% of the exterior surface has rough, dark brown to black fusion crust. The exposed interior is dark gray with visible chondrules. Evaporites and polygonal fractures are present. The interior matrix is medium gray color with vague gray chondrules and inclusions.
Thin Section Description (,2) - Cari Corrigan and Linda Welzenbach
The section consists of large (up to 2 mm), well-defined chondrules in a matrix of finer-grained silicates, sulfides and abundant magnetite. The meteorite is lightly weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa28-29 and orthopyroxene is Fs17-28Wo1-22. Feldspars are An25-51Wo1-4. The meteorite appears to be a CK4 chondrite.
