Macroscopic Description: Robbie Marlow
Dark brown fusion crust covers 95% of the exterior. It is smooth and shiny in areas. This meteorite is heavily weathered. No features were noted in the dark red brown, fine-grained matrix.

Thin Section (,2) Description: Brian Mason
The section shows numerous chondrules, up to 0.2 mm across, abundant pyroxene grains (up to 0.1 mm), and a considerable amount of nickel-iron. The meteorite is severely weathered, with veins and patches of red-brown limonite throughout the section. Most of the pyroxene is close to MgSiO3 in composition, but ranges up to Fs19. The metal contains up to 0.2% Si. The meteorite is a carbonaceous chondrite of the ALH85085 grouplet.
