Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Used extensively in construction, countertops, monuments, tiles, and as a decorative 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 speckled pink, white, and black crystalline appearance. Commonly found in mountainous regions and continental shields worldwide.
