Macroscopic Description: Robbie Marlow
Shiny, smooth, dark-brown fusion crust covers ninety-five percent of the exterior of this chondrite. The interior is composed of weathered, brownish-black matrix. Oxidation is extensive and evaporite deposit was noted in the interior.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules (up to 2.4 mm across), chondrule fragments, and mineral grains in a small amount of black matrix. The meteorite is severely weathered, with only traces of nickel-iron and troilite remaining. Microprobe analyses show a wide range in olivine and pyroxene compositions: olivine, Fa7-28, mean Fa14; pyroxene, Fs6-26. The meteorite is classified as an L3 Chondrite (estimated L3.5).
