85% of exterior is covered with fusion crust that is slightly shiny on one side but rough and vesicular on the other. The shiny side also has some radial flow lines and a few white spots that might be evaporites. Exterior surfaces are dark red-brown and porous. Fresh interior is very dark grey-black matrix with a crystalline texture and some small (<0.5 mm) white inclusions. Orange rust throughout. |
