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. Unaltered olivine or pyroxene grains of sufficient size for microprobe analyses were not found.
