Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, monuments, countertops, paving, and architectural facing.
Geological facts
Granite is the most common igneous rock in the Earth's continental crust and forms the core of many mountain ranges.
Field identification & locations
Easily identified by its interlocking, visible mineral grains of quartz, feldspar, and mica. Found worldwide in continental shields and intrusive plutons.
