Physical properties

Hardness of 6 on the Mohs scale; colors vary from pink to gray depending on mineral 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, architectural buildings, monuments, countertops, and decorative stone.

Geological facts

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

Field identification & locations

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