Physical properties
Hardness of 6-7 on Mohs scale, commonly pink, gray, or white with visible mineral crystals, vitreous to dull luster, specific gravity of 2.65-2.75.
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali feldspar deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction for countertops, flooring, monuments, and curbing due to its high durability and resistance to weathering.
Geological facts
Granite is the most common intrusive rock on Earth and forms the foundation of many continental mountain ranges.
Field identification & locations
Identify by interlocking quartz, feldspar, and mica grains; found globally in continental shields and intrusive mountain cores.
