Can a volcano or earth quake squeeze surface rock so hard it causes it to bleed glass? And then throw it in the air with enough force to cause the glass to form a dendritic pattern? On one side of the rock? The rock is white and looks like anorthosite. The surface of the rock is peach colored and ripled like regmalypts. The glass is black and shiny with some splatering and flattened and in some places encrusted with dirt when it landed while still melted. The glass looks like tar that was dropped onto the ground. I at first thought it was road tar mixed with rocks and dirt. But it doesnt disolve in gasoline or melt under a torch. It looks kind of like you took a white sponge and squeezed it to ooze out black shiny paint. The side that looks like regmalypts also has a few spots that look like zap pits. Any Idea what would make glass dendrites? Have a great day Steve
