On average the upper continental crust has the same composition as granodiorite.
Granodiorite is a plutonic igneous rock, formed by an intrusion of silica-rich magma, which cools in batholiths or stocks below the Earth's surface. It is usually only exposed at the surface after uplift and erosion have occurred. The volcanic equivalent of granodiorite is dacite.
Granodiorite is most often used as crushed stone for road building. However, it is also used as ornamental stone.
