Formed from the slow crystallization of magma deep beneath the Earth's crust over millions of years.
Uses & applications
Widely used as a dimension stone in construction, building facades, kitchen countertops, and monuments.
Geological facts
Granite makes up a major part of the Earth's continental crust and is exceptionally durable against weathering.
