Macroscopic Description - Cecilia Satterwhite
Brown/black fusion crust covers the exterior of this flat meteorite with some iridescent areas. The interior is a black matrix with some metal and some brown weathered areas. Abundant mm sized inclusions are visible, lighter than the matrix, and some are weathered.
Thin Section (,2) Description - Cari Corrigan and Linda Welzenbach
The section exhibits large (up to 1 mm), moderately-defined, metal-poor chondrules and rare CAI’s in a dark matrix of FeO-rich phyllosilicate. Silicate analyses shows olivines Fa2-6, and pyroxenes Fs1-2Wo1. The meteorite is probably a CR3 chondrite.
