Macroscopic Description - Mitchell Haller | |
There is a patch of porous black fusion crust on the exterior with moderate fractures. Areas without fusion crust are black/gray/greenish and smooth texture. Some small inclusions are visible. The black matrix has small white inclusions and chondrules. | |
