Physical properties

Hardness of 6 on the Mohs scale, typically pink, white, gray, or black with a phaneritic (coarse-grained) texture, vitreous to dull luster, and poor to indistinct cleavage. Specific gravity ranges from 2.65 to 2.75.

Formation & geological history

Formed from the slow crystallization of magma below the Earth's surface over millions of years, commonly found in continental crusts.

Uses & applications

Widely used in construction, monuments, countertops, paving, and architectural facing.

Geological facts

Granite is the most common plutonic rock on Earth's surface and forms the core of many major mountain ranges.

Field identification & locations

Easily identifiable in the field by its interlocking visible crystals of quartz, feldspar, and dark minerals like biotite or hornblende. Commonly found globally in shields and orogenic belts.
