Physical properties

Hardness of 6 on the Mohs scale, composed mainly of quartz, alkali feldspar, and plagioclase. Displays a phaneritic, coarse-grained crystal structure with a dull to glassy luster and variable pink, white, or gray colors.

Formation & geological history

Formed through the slow cooling and crystallization of magma beneath the Earth's surface over millions of years. Common in continental crust worldwide.

Uses & applications

Widely used in construction for countertops, floor tiles, and monumental architecture due to its high durability and weather resistance.

Geological facts

Granite makes up a major portion of the Earth's continental crust and is exceptionally resistant to weathering compared to sedimentary rocks.

Field identification & locations

Easily identified by its interlocking, visible mineral grains of quartz, feldspar, and dark biotite mica. Found abundantly in mountain ranges and shield regions globally.
