Physical properties
Hardness of 6 on the Mohs scale, colors typically pink, white, gray, or black, vitreous to dull luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metal oxides deep beneath the Earth's surface over millions of years.
Uses & applications
Commonly used in construction, countertops, monuments, and as a decorative stone.
Geological facts
Granite is the most common rock of the Earth's continental crust and is frequently found in major mountain ranges.
Field identification & locations
Easily identified by its visibly intergrown crystals of quartz, feldspar, and mica. Found worldwide in continental shields and intrusive plutons.
