Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years.
Uses & applications
Widely used in construction, monuments, countertops, and architectural facing stone.
Geological facts
Granite is the most common rock of Earth's continental crust and is exceptionally durable.
