Macroscopic Description - Mitchell Haller | |
Black/Brown fusion crust covers 50% of the exterior with some gray matrix visible on non-fusion crust surface. Some brown rust/oxidation is present and the sample is brittle. The matrix is light gray with darker inclusions/chondrules. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of large (up to 1 mm), poorly-defined chondrules in a matrix of finer-grained silicates, sulfides and very abundant magnetite. The meteorite is little weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa33 and clinopyroxene is Fs9-11Wo46. The meteorite is a CK5 chondrite. |
