Physical properties

Hardness of 6 on the Mohs scale, pink to gray color, vitreous to dull luster, phaneritic crystal structure, and specific gravity of 2.65 to 2.75.

Formation & geological history

Forms from the slow cooling of silica-rich magma deep underground, typically during continental crust-forming geological events.

Uses & applications

Widely used in construction for countertops, flooring, and monuments, as well as crushed aggregate in civil engineering.

Geological facts

Granite is the most common rock of Earth's continental crust and is exceptionally resistant to weathering.

Field identification & locations

Identified by its interlocking visible grains of quartz, feldspar, and mica; commonly found in mountain ranges and shields worldwide.
