Physical properties
Hardness of 6-7 on the Mohs scale, colors typically range from pink, white, grey to black depending on feldspar content, vitreous to dull luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly found in continental crusts.
Uses & applications
Widely used in construction, monuments, countertops, flooring, and decorative aggregate.
Geological facts
Granite is the most common rock of Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its visible interlocking grains of quartz, feldspar, and micas. Found globally in major mountain ranges and shield areas.
