Physical properties
Hardness of 6 on the Mohs scale, pink to gray or white color, vitreous to dull luster, phaneritic crystal structure, and specific gravity around 2.65.
Formation & geological history
Formed through the slow cooling of silica-rich magma beneath the Earth's surface, typically originating in continental crust over millions of years.
Uses & applications
Widely used in construction for countertops, flooring, monuments, and curbing due to its high durability.
Geological facts
Granite is the most common intrusive rock on Earth's continents and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its visibly interlocked quartz, feldspar, and biotite mica grains; commonly found globally in shield areas and mountain roots.
