Macroscopic Description: Kathleen McBride
90% of the exterior has shiny, black fusion crust with thin “ripples”. The interior is a light gray matrix with gray, black, and white angular clasts. A few rust halos are visible.

 

Thin Section (,2) Description: Tim McCoy, Linda Welzenbach and Cari Corrigan
This meteorite is dominated by fine-grained basaltic material which occurs as both the host and clasts. Occasional coarser-grained clasts, with grain sizes up to 2 mm, are observed. Pyroxene exhibits a range of compositions from orthopyroxene of Fs58Wo3 to augite of Fs29Wo41. Single pyroxene grains often exhibit lamellae of orthopyroxene and augite. Plagioclase is An90Or0.5. The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.
