Formation & geological history
Formed from the slow cooling and solidification of magma rich in silica and alumina beneath the Earth's surface over millions of years.
Uses & applications
Widely used as a dimensional stone in construction, countertops, monuments, and architectural facings due to its extreme durability.
Geological facts
Granite is the most common rock of the Earth's continental crust and forms the core of many major mountain ranges.
