Macroscopic Description: Kathleen McBride
Black, glassy, vesicular fusion crust is on the exterior of this achondrite. The fusion crust on the bottom surface is very thick and shiny. Two areas are lacking fusion crust. The interior has a granular or gritty texture. The matrix is off white in color with clasts of numerous colors and sizes, plagioclase, pyroxene, olivine, FeMg minerals and some metal grains are all present. Some rusty patches are present.

Thin Section (,5) Description: Tim McCoy
QUE97004 - Cross-Polarized Light The section is a microbreccia of pyroxene and plagioclase clasts and mineral fragments. Much of the section exhibits a granoblastic texture. Pyroxene compositions are quite homogeneous, with low-Ca pyroxene of Fs59Wo6 and augite of Fs30Wo40. Plagioclase ranges from An85-91. The Fe/Mn ratio in pyroxene is about 30. The meteorite is a brecciated eucrite.
