Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years. Common in continental crust.
Uses & applications
Used in construction, countertops, monuments, dimension stone, and curbing.
Geological facts
Granite is the most common rock of Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Identified by its interlocking, visible mineral grains of quartz, feldspar, and mica. Widely distributed globally.
