Physical properties

Hardness of 6 on the Mohs scale, mottled pink and gray color, vitreous luster, granular phaneritic crystal structure, and a specific gravity around 2.65.

Formation & geological history

Formed from the slow cooling of silica-rich magma deep underground, typically over millions of years within continental crust.

Uses & applications

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

Geological facts

Granite makes up a major component of the Earth's continental crust and is rarely found on any other planet in the solar system.

Field identification & locations

Easily identified in the field by its interlocking visible grains of quartz, feldspar, and dark minerals like biotite.
