Macroscopic Description: Carol Schwarz Fusion crust is dull, black, and has a rough texture. The interior matrix is dark gray/black and fine-grained. Some metal is present. Evaporite deposit is abundant; it is mostly white along the edge of the fusion crust and red-brown or yellowish in the interior.
Thin Section (,2) Description: Brian Mason The section shows numerous chondrules and irregular aggregates, up to 2.4 mm across, in a black matrix. A minor amount of fine-grained metal and troilite is present, mainly concentrated within chondrules. Brown limonitic staining pervades the section. Microprobe analyses show that most of the olivine in the chondrules is close to Mg2SiO4 in composition, but ranges up to Fa10; pyroxene composition is Fs1-6. The matrix appears to consist largely of iron-rich olivine, about Fa50. The meteorite is classified as a C3 chondrite of the Vigarano subtype.
