What Is Granite And How Is It Formed? - Geology In

Granite has a felsic composition and is more common in recent geologic time in contrast to Earth& 39;s ultramafic ancient igneous history. Felsic rocks are less dense than mafic and ultramafic rocks and thus they tend to escape subduction whereas basaltic or gabbroic rocks tend to sink into the mantle beneath the granitic rocks of the continental cratons.
