Physical properties
Hardness of 6 on the Mohs scale, colors range from pink to gray depending on feldspar content, vitreous to dull 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, typically found in continental crust.
Uses & applications
Widely used in construction, monument building, countertops, and architectural facing stone.
Geological facts
Granite is the most common intrusive rock on Earth's crust and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its speckled, interlocking mineral grains of quartz, feldspar, and mica. Found globally in continental shields.
