Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
This very small section consists of large (up to 2 mm), well-defined chondrules in a matrix of finer-grained silicates, sulfides and magnetite. The meteorite is little weathered, but extensively shock blackened. Silicates are homogeneous. Olivine is Fa30 and orthopyroxene is Fs23. The meteorite appears to be a CK5 chondrite. |
