I continue to miss the relevance here. . .so you take granite with mica flakes and melt it down and we are supposed to be surprised that the resulting igneous rock is relatively homogeneous?Ã‚Â Take some flakes of butter and sprinkle them into a glass of milk, if you microwave your cup are you going to be surprised that you end up with a homogeneous mixture?Ã‚Â The rock is relatively homogeneous because it's been melted down again. . .so what?
Gee I don't know instructorous--maybe like what caused the mica flakes in the first place?? Like what conditions caused the granite to be formed into the composition that it is in. Why is it not homogeneous in the first place? Maybe that is why scientists are still discussing what is the origin of granite. Are you aware of this fact?
Your illustration of flakes of butter in milk forgets the fact that 1) butter and milk were formed separately, in contrast with the elements of granite. 2) that the granite has already been melted once.
Or were you actually try to tell us that someone sprinkled the mica flakes in?
