Macroscopic Description: Kathleen McBride
The exteriors of these diogenites have smooth, shiny black fusion crust. The interiors are fine-grained, medium gray matrix with light gray and cream colored inclusions.

Thin Section (,2) Description: Tim McCoy, Linda Welzenbach
These sections show a groundmass of coarse (up to 2 mm) comminuted pyroxene with minor SiO2, olivine (Fa25-29) and plagioclase (An90). Orthopyroxene has a composition of Fs17-26Wo2-3 and an Fe/Mn ratio of ~28-30. The meteorites are diogenites and are probably paired.
