Formation & geological history
Formed from the slow cooling of silica-rich magma beneath the Earth's surface over millions of years.
Uses & applications
Commonly used in construction, countertops, monuments, and curbing.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally durable.
Field identification & locations
Easily identified by its speckled appearance showing interlocking crystals of quartz, feldspar, and mica. Found worldwide in continental shields and mountain ranges.
