Macroscopic Description: Kathleen McBride
50% of the exterior has a dark brown, dull fusion crust. The interior is light gray matrix with white and tan inclusions < 1 mm in size.

Thin Section (,3) Description: Tim McCoy, Linda Welzenbach
The sections are composed of a groundmass of pyroxene and plagioclase (up to 0.5 mm) with few basaltic clasts. Pyroxene grains are mixtures of orthopyroxene and augite with exsolution lamellae of 1-5 microns. Most pyroxene analyses were intermediate compositions, but end members appear to be FeO-rich with orthopyroxene of Fs61Wo3 and augite of Fs28Wo41 (Fe/Mn ~ 30). Plagiolcase is An90. The meteorite is a brecciated eucrite.
