Formation & geological history
Formed from the slow crystallization of magma below Earth's surface, often associated with continental crust and mountain-building processes over millions of years.
Uses & applications
Widely used in construction, monuments, countertops, flooring, and decorative stone due to its durability.
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 in the field by its interlocking, visible grains of quartz, feldspar, and mica. Found globally in major mountain ranges and shields.
