Formation & geological history
Formed from the slow crystallization of magma below Earth's surface (intrusive igneous rock). Geologic age varies from Precambrian to recent.
Uses & applications
Extensively used in construction, monument making, architecture, countertops, and abrasive aggregates.
Geological facts
Granite is one of the most common rocks in the continental crust and constitutes a significant portion of many mountain ranges.
Field identification & locations
Identify by its coarse-grained texture and light color with visible distinct minerals (quartz, feldspar, mica). Found worldwide in continental crust.
