Physical properties
Hardness of 6 on the Mohs scale with a phaneritic texture. Composed primarily of quartz, alkali feldspar, and plagioclase.
Formation & geological history
Formed from the slow cooling and crystallization of silica-rich magma deep underground, often dating from the Precambrian to Cenozoic eras.
Uses & applications
Widely used in commercial construction, dimension stone, kitchen countertops, and monuments.
Geological facts
Granite is the most common rock of Earth's continental crust. Its interlocking crystal structure makes it extremely durable against weathering.
