Macroscopic Description: Kathleen McBride
The exterior has purplish black fusion crust with some fractures. The interior is black with a few mm sized light colored chondrules. 718 has an evaporate rim.

Thin Section (,2) Description: Cari Corrigan, Tim McCoy
The sections consist of a few small chondrules (up to 0.5 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa1-48, with a peak at Fa0-2; orthopyroxene is Fs1. The matrix consists dominantly of an Fe-rich serpentine. The meteorites are CM2 chondrites.
