Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface, typically over millions of years.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Common in continental mountain ranges and shields worldwide.
