Physical properties

Mohs hardness of 6-7; colors range from pink to gray; phaneritic texture with visible quartz, alkali feldspar, and plagioclase crystals; dull to vitreous luster.

Formation & geological history

Formed from the slow crystallization of magma beneath the Earth's surface over millions of years, commonly found in continental shields and mountain cores.

Uses & applications

Extensively used in construction, architectural building facades, countertops, and monumental sculpture due to its extreme durability.

Geological facts

Granite makes up a major part of the Earth's continental crust and is rarely found on any other planet. It is one of the toughest natural stones available.

Field identification & locations

Easily identified in the field by its speckled, interlocking crystalline matrix of quartz, feldspar, and mica. Widely distributed globally.
