Formation & geological history
Formed from the slow cooling of silica-rich magma deep beneath the Earth's crust over millions of years.
Uses & applications
Widely used in construction for dimension stone, countertops, monuments, and architectural facings.
Geological facts
Granite forms the major part of the continental crust and often hosts rare minerals within its late-stage pegmatite pockets.
