Physical properties
Hardness of 6-7 on the Mohs scale, colors range from pink to white with dark mineral specks, vitreous to dull luster, phaneritic crystal structure, and specific gravity around 2.65-2.75.
Formation & geological history
Formed by the slow crystallization of magma beneath the Earth's surface, typically over millions of years in continental crustal environments.
Uses & applications
Widely used in construction, architectural monuments, countertops, and decorative stone flooring.
Geological facts
Granite is the most common intrusive rock on Earth and forms the core of many major mountain ranges.
