Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metal oxides beneath the Earth's surface over millions of years.
Uses & applications
Commonly used in construction, countertops, monuments, and architectural facings due to its durability and aesthetic appeal.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently found in continental shield areas.
