Macroscopic Description - Cecilia Satterwhite
The exteriors have shiny black fractured fusion crust. Areas without fusion crust are a dark gray with some black grains and white inclusion. The interiors are light to medium gray matrix and have abundant small black grains and white inclusions.
Thin Section Description (,2) - Cari Corrigan, and Andrew Beck
These meteorites are dominated by fragments of fine-grained basaltic material, with grains ranging from ~50-150 microns, set in a matrix of comminuted pyroxene. A large basaltic clast (4 mm x 5 mm) makes up approximately 30% of the MIL 11291 section. In this clast, the pyroxene and plagioclase grains are both rounded and euhedral and grain sizes are approximately equal. Mineral compositions are homogeneous with orthopyroxene (Fs62Wo2), with lamellae of augite (Fs25Wo45), and plagioclase (An87-89Or0-1). The Fe/Mn ratio of the pyroxene is ~29-30. These meteorites are brecciated eucrites.
