The name scientificially describes granitization in formation of separate mineral crytals large enough, and containing oxygen so it floated on the molten surface... or better, pliable, semiplastic surface as a a crust. It lacked mica, hence the diorite, but resemble granite otherwise, hence grano. Trondjemite is crystal mineralization. Tonalite is literally a whole makeup, or tone of the rock.

Most of that rock has been subducted, so is rare to find anywhere on the surface. An altered rock above the basaltic mantle in North America are the precambrian acasta and greenstone gneisses of the Canadian shield. Some of that may sit under Sia's house! Its the kind of wavy, pretty black and white striped or mottled bent up rock you see.

Just to tease and be mean, Sia, do you remember when that was laid down before your house was built? Scientists date it from 4.0 to about 4.3 billion years ago.

We can't rely on trump, because while this rock formed a kind of crust, his expertise is in scum.
