Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and is exceptionally durable against weathering
