Macroscopic Description: Kathleen McBride
Thin black fusion crust covers 50% of the exterior surface of this achondrite. It has a dull luster and the exposed interior shows a variety of clasts. Some rusty patches are visible and some shiny patches are present on the fusion crust. The interior has numerous clasts of various sizes and colors. It has a concrete gray matrix, dull with a sandy texture. A large area of olivine and smaller gray aphanitic clasts, white clasts, black and white brecciated clasts and brown clasts are visible.

Thin Section (,5) Description: Tim McCoy
QUE97001 - Cross-Polarized Light The section is a microbreccia of pyroxene with minor plagioclase and a few basaltic clasts. Individual clasts range up to 4 mm across. Most of the pyroxene is low-Ca with compositions ranging from Fs17Wo1 to Fs54Wo1. One augite grain of Fs24Wo42 was analyzed. Plagioclase ranges from An72-94. The Fe/Mn ratio in pyroxene is about 30. The meteorite is a howardite.
