Granite - College of Natural Resources, UC Berkeley

Originally granite was thought to form mainly from magmatic differentiation of basaltic magma, but geologists now believe there is simply too much of it for it to have formed this way, except locally. Most granite seems to have formed either by melting, partial melting, or metamorphism of deeply buried shale and sandstone.
