Physical properties

Hardness 6 on Mohs scale; pink, white, or gray with speckled mineral grains; vitreous to dull luster; phaneritic crystal structure; specific gravity 2.65-2.75.

Formation & geological history

Formed from the slow cooling and crystallization of magma rich in silica and alkali feldspar deep beneath Earth's crust.

Uses & applications

Widely used in commercial construction, kitchen countertops, monuments, and architectural facings.

Geological facts

Granite is the most common intrusive rock on Earth's continental crust and forms the structural core of many major mountain ranges.

Field identification & locations

Identified by visible interlocking crystals of quartz, feldspar, and micas. Found globally in continental shields and intrusive plutons.
