Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface over millions of years, commonly found in continental crust across all geological eras.
Uses & applications
Extensively used in construction, monument building, countertops, floor tiles, and architectural facing stone.
Geological facts
Granite is the most common intrusive rock in the Earth's continental crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visibly crystalline, speckled appearance containing quartz, feldspar, and mica. Found worldwide in ancient shields and mountain roots.
