Formed from the slow cooling and solidification of magma rich in silica and alkali feldspar deep underground over millions of years.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings due to its high durability.
Geological facts
Granite makes up a major part of Earth's continental crust and is exceptionally resistant to weathering.
