Formation & geological history

Formed from the slow cooling and solidification of magma deep beneath the Earth's surface over millions of years.

Uses & applications

Widely used in construction, monument building, countertops, floor tiles, and architectural facing.

Geological facts

Granite forms the core of many major mountain ranges and is one of the most abundant rocks in the Earth's continental crust.

Field identification & locations

Easily identified by its interlocking, visible grains of quartz, feldspar, and mica. Found globally in continental shields and orogenic belts.
