Thin Section Description (,2) - Cari Corrigan, Linda Welzenbach | |
The section consists of a few small chondrules (up to 0.5 mm) that have been completely replaced by phyllosilicate set in an Fe-rich serpentine matrix. No isolated mineral grains or CAIs are apparent; sulfide grains are present as are abundant coarse carbonate grains. The section exhibits a strong fabric formed by the alignment of elongated remnant chondrules. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found. This meteorite is a CM1 chondrite. |
