Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years. Common in continental crusts.
Uses & applications
Widely used in construction, monuments, countertops, flooring, and decorative building stone.
Geological facts
Granite is the most common intrusive rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its distinct interlocking mineral grains of quartz, feldspar, and mica. Found worldwide in mountainous regions and shield areas.
