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.
