Physical properties
Hardness of 6 on the Mohs scale, varying colors from pink to gray, sub-to-euhedral crystal structure with phaneritic texture, and specific gravity around 2.65.
Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in commercial construction, monuments, countertops, and architectural facing stone.
Geological facts
Granite forms the core of many major mountain ranges and is the most abundant rock in the continental crust.
Field identification & locations
Easily identified by its visibly crystalline, speckled texture containing interlocking mineral grains of quartz and feldspar, found globally in continental shields.
