Physical properties
Hardness of 6 on the Mohs scale, colors range from pink to gray depending on feldspar content, dull to vitreous luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly found in continental crust.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Identified by visible interlocking mineral crystals of quartz, feldspar, and mica; found globally in major mountain ranges and shields.
