Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, typically in continental crust.
Uses & applications
Used extensively in construction, countertops, monuments, flooring, and architectural facings.
Geological facts
Granite is the most common intrusive rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Identify by its visible interlocking crystals of quartz, feldspar, and dark minerals like biotite mica. Common globally in major mountain ranges and shield areas.
