Macroscopic Description - Kathleen McBride and Cecilia Satterwhite
The exteriors have brown/black fusion crust with polygonal fractures. The interiors of these diogenites have tan matrices with dark gray to black “marbled” areas; some have light and dark inclusions. Some exhibit minor oxidation and rust.
Thin Section Description (,3) - Cari Corrigan, Andrew Beck, and Nicole Lunning
These meteorites are similar enough that one description suffices. The sections show a groundmass of coarse (up to 1.5 mm) comminuted pyroxene, with minor plagioclase, euhedral and chromites. MIL 11202 contains a large (1.5 mm) chromite grain, and MIL 11204 contains a large (2.0 mm) plagioclase grain. Pyroxene compositions are Fs_11-35Wo_4-44 and plagioclase is An_78-87Or_0-1. The Fe/Mn ratio of the pyroxene is ~29. The meteorites exhibit numerous shock features and are brecciated diogenites.
