Macroscopic Description - Mitchell Haller | |
A patch of steel 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. The edges near the exterior are a greenish color. | |
