Macroscopic Description: Kathleen McBride
The exterior has 60% dark brown to black fusion crust with very fine grained wrinkled texture. The fusion crust exhibits a slight sheen. The interior is a gray and black matrix that is fine grained and very hard.

Thin Section (,2) Description: Tim McCoy, Lauren LaCroix and Linda Welzenbach
The section is composed of a coarse-grained assemblage of pyroxene, olivine and maskelynite. Olivine occurs as phenocrysts with grain sizes up to 2.5 mm. Pyroxene and maskelynite in the matrix are finer grained, typically reaching 0.5 mm. Sulfides and oxides are present, as are shock melt veins. Olivine is Fa_25-48; pyroxenes exhibit a range of compositions from pigeonite to subcalcic augite (Fs_25-51Wo_5-31; Fe/Mn ~ 23-35); feldspar is intermediate in composition (An_46-52). The meteorite is an olivine-phyric shergottite.

Oxygen Isotopic Analysis: Z. Sharp, University of New Mexico
Oxygen isotopic analyses of two small (2-5 mg) pieces yielded the following results which fall in the martian meteorite field:
