Thin Section Description (,2) - Cari Corrigan, Tim McCoy | |
This tiny section consists of a few small chondrules that have been completely replaced by phyllosilicate, set in an Fe-rich serpentine matrix. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found. The meteorite is a highly altered CM chondrite probably of petrologic type 1. |
