re: #48 klys
Oh, I’ve seen them. Used them. Can even vaguely read them.
But when you’re dealing with melt, crystal structure is of less interest, and ideally you want no crystals at all. They get in the way of analyzing melt structure, which is already a special clusterfuck of its own.
But also…you end up with migmatites and weird depleted dunnites after the melt leaves the system. You didn’t have fun with those??!
