Formed from the slow cooling of magma rich in silica and alkali metal oxides deep beneath the Earth's crust over millions of years.
Uses & applications
Widely used in commercial construction, kitchen countertops, monuments, and architectural facings.
Geological facts
Granite forms the core of many major mountain ranges and is one of the most abundant rocks in Earth's continental crust.
