Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's crust over millions of years.
Uses & applications
Widely used in construction for countertops, floor tiles, and monuments due to its extreme durability and polished aesthetic.
Geological facts
Granite is the most common rock of Earth's continental crust and is unique to our planet among the inner solar system bodies.
Field identification & locations
