The sections consist of a few small chondrules (up to 1 mm), mineral grains and CAIs set in a black matrix. Olivine compositions are Fa0-31, with most less than Fa2, and orthopyroxene is Fs0-7. In thin sections, these meteorites exhibit fracturing and flattening of chondrules along a preferred orientation. The matrix is an iron-rich serpentine which occurs in spheres of ~200 microns in diameter, with each sphere exhibiting a fibrous internal texture. Parting of the meteorites occurs between these spheres. The meteorites are CM2 chondrites
