Macroscopic Description - Kellye Pando | |
85% of exterior is covered with rough, fractured, black frothy fusion crust. Exposed area is very dark grey-black. Fresh interior is dark grey-black matrix with some like orange-yellow weathering concentrated near exterior edges. | |
Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
The section consists of a few (up to 1 mm), poorly-defined chondrules in a matrix of finer-grained silicates, sulfides and magnetite. The meteorite displays moderate weathering and is very extensively shock blackened. Silicates are homogeneous. Olivine is Fa26. No pyroxene analyses were obtained. The meteorite appears to be a CK6 chondrite. |
