Macroscopic Description - Cecilia Satterwhite | |
Black exterior with some patches of fusion crust; interior is a gray matrix with minor oxidation and some light inclusions. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of large (up to 1.5 mm), poorly defined chondrules in a matrix of finer-grained silicates, sulfides and abundant magnetite grains. The meteorite is little weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa30 and orthopyroxene is Fs25. The meteorite is a CK5 chondrite. |
