QUE93009

Macroscopic Description: Cecilia Satterwhite
Ninety percent of the exterior of this diogenite is covered with fractured, shiny, black fusion crust. The interior matrix is gray. A few small, angular, black clasts, abundant white (plagioclase?) clasts, and greenish grains are present. One large green inclusion measures 4 x 3 mm.

Thin Section (,6) Description: Brian Mason
The section shows a microbreccia of pyroxene and minor plagioclase, with angular clasts up to 3 mm across in a comminuted groundmass of these minerals. Pyroxene is fairly uniform in composition, averaging Wo3Fs28; plagioclase composition ranges from An84 to An90. The meteorite is a diogenite.
