Physical properties
Hardness of 6 on the Mohs scale, typically grayish, pinkish, or white in color with a phaneritic (coarse-grained) texture and dull to vitreous luster. Composed mainly of quartz, alkali feldspar, and plagioclase.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly associated with continental crust and mountain-building processes.
Uses & applications
Widely used in construction, monuments, floor tiles, countertops, and facing stone due to its durability and aesthetic appeal.
Geological facts
Granite is the most common rock of Earth's continental crust and is strong enough to resist most forms of weathering.
Field identification & locations
Identifiable by its visible interlocking mineral crystals of quartz, feldspar, and dark biotite mica. Found globally in large batholiths and shield areas, and is a staple rock for amateur and professional geologists alike.
