Physical properties
Hardness of 6 on the Mohs scale, colors vary widely including pink, white, gray, and green due to mineral content, luster is typically dull to vitreous, crystal structure is phaneritic (coarse-grained), specific gravity is approximately 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, typically associated with continental crust and mountain-building processes.
Uses & applications
Commonly used in construction, monuments, flooring, countertops, and landscaping.
Geological facts
Granite makes up a major part of continental crusts and is one of the most durable natural building stones available.
Field identification & locations
Easily identified by its visibly speckled or crystalline texture containing quartz, feldspar, and mica. Found globally in continental shields and mountain ranges.
