Physical properties

Hardness of 6 on the Mohs scale, colors ranging from pink to gray depending on mineral 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 paving stones.

Geological facts

Granite is the most common igneous rock in the Earth's continental crust and is exceptionally durable against weathering.

Field identification & locations

Easily identified by its visibly interlocking crystals of quartz, feldspar, and mica. Found globally in mountain ranges and shield areas.
