Macroscopic Description - Kathleen McBride
90% rough brown/black fusion crust with polygonal fractures covers the exterior surface. The interior is a fine grained brown/black matrix with evaporites. The meteorite has a rusty oxidation rind and small (mm sized) rust colored chondrules are visible.
Thin Section (,3) Description - Tim McCoy and Linda Welzenbach
The section consists of abundant small (up to 1 mm) chondrules, chondrule fragments and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa1-50, with a strongly bimodal distribution (Fa0-1 and Fa40-50). Two pyroxene analyses range from Fs3-41. The meteorite is a CO3 chondrite.
