re: Sure, but please elaborate your theory!
When I look at these latest pans, I just have to laugh at you geologists, you are so wrapped up in your preconceptions and terminology, it's almost like you aren't actually looking at the pictures.
This stuff looks like basaltic mud splat with things growing in them, fossils, I suppose they would have to be highly evolved extremophiles. It sure as hell isn't andesite, it seems to be entrained with shocked shattered bits of andesite like basalt, obviously. When you melt rock in water by impact and volcanism, I suppose you get something like andesite. Those aren't necessarily radiating crystals, they could just be smashed up fragments.
I see where water was literally running out of the hills. Of course, I'm just a crank. You knew that.
