snow lava and molten snow
It's mostly because you have traces of gold and exotic, if they were to be melted together, it would form vibranium lava, which's "freezing" point is pretty cold. So while you were cooling yourself, the vibranium didn't cool so that's why it's there.
HOLD UP YOU HAVE TRACES OF VIBRANIUM?
