Physical properties

Hardness of 6 on the Mohs scale, granular phaneritic texture, and typically speckled pink, white, gray, or black. Composed mainly of quartz, alkali feldspar, and plagioclase.

Formation & geological history

Formed from the slow cooling of silica-rich magma far beneath the Earth's surface over millions of years.

Uses & applications

Widely used in construction for countertops, flooring, monuments, and architectural facings due to its extreme durability.

Geological facts

Granite makes up a major part of the Earth's continental crust and is exceptionally resistant to weathering.

Field identification & locations

Identify by its interlocking visible mineral grains and overall speckled appearance. Found globally in major continental shields and mountain ranges.
