Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years. Commonly associated with continental crustal formation.
Uses & applications
Widely used in construction, architectural buildings, countertops, monuments, and paving stones.
Geological facts
Granite is the most common intrusive rock of Earth's continental crust and is famous for its exceptional durability and resistance to weathering.
Field identification & locations
Easily identified by its characteristic coarse-grained, speckled appearance containing quartz, feldspar, and mica. Found abundantly worldwide in mountainous regions and shield areas.
