Macroscopic Description - Mitchell Haller
A patch of black fusion crust covers 5% of the exterior. Areas without fusion crust have a porous greenish tint with minor fractures. The interior is a black matrix with gray inclusions/chondrules. Greenish color is visible around the edges near the exterior.
Thin Section Description (,2) - Cari Corrigan, Tim McCoy
