Macroscopic Description - Kathleen McBride
Brown/black to black fusion crust with shiny black patches covers the exterior of these rocks. The crust exhibits polygonal fractures and areas of ropy, rough textured patches. These meteorites have gray matrix with numerous inclusions and angular clasts in a wide range of sizes (mm to cm) and colors (dark gray, black, white, cream and green).
Thin Section (,2) Description - Cari Corrigan, Linda Welzenbach, Andrew Beck and Nicole Lunning
These meteorites show a groundmass of comminuted pyroxene and plagioclase (up to 0.5 mm) with fine- to coarse-grained basaltic clasts ranging up to 5 mm. Basaltic material occurs as the host rock and as clasts within these meteorites. Half of DOM 10105 is dominated by a 1 cm diogenitic clast. More than half of DOM 10837 is comprised of an impact melt clast. Most pyroxene is orthopyroxene with compositions ranging from Fs21-52Wo1-4 (most Fs20-30). Some augite of Fs12-19Wo32-50 are present, as are rare olivines of Fa12. These meteorites are howardites.
