Formation & geological history
Formed from the slow crystallization of magma below Earth's surface, typically dating back millions to billions of years across continental shields.
Uses & applications
Widely used in construction, architectural buildings, monuments, kitchen countertops, and landscaping.
Geological facts
Granite is the most common rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Identifiable by its visible interlocking crystals of quartz, feldspar, and mica. Found abundantly in mountain ranges and continental cores worldwide.
