Formation & geological history
Formed from the slow cooling and crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural building, countertops, monuments, and curbing.
Geological facts
Granite is the most common intrusive rock of Earth's continental crust and is exceptionally durable.
Field identification & locations
Easily identified by its speckled appearance with visible interlocking crystals of quartz, feldspar, and mica. Found globally in mountainous regions and continental shields.
