Formation & geological history

Formed from the slow cooling of silica-rich magma deep underground, occurring across all major continental shields.

Uses & applications

Widely used in dimensional stone, construction, monuments, countertops, and architectural facing.

Geological facts

Granite is the most common plutonic rock on Earth and forms the foundation of many continental mountain ranges.
