Formed from the slow cooling and crystallization of magma beneath the Earth's surface, often dating back billions of years across continental shields.
Uses & applications
Widely used in construction, monument building, countertops, and architectural facing 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 major mountain ranges around the world.
