Physical properties
Hardness of 6 on the Mohs scale, colors vary from pink to gray depending on mineral composition, dull to vitreous luster, phaneritic crystal structure with visible interlocking mineral grains, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface over millions of years, typically found in continental crust.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, and decorative paving stones.
Geological facts
Granite makes up a major part of the continental crust of the Earth and is one of the most durable natural building materials available.
Field identification & locations
Identified easily by its speckled, coarse-grained appearance containing quartz, feldspar, and mica. Found globally in mountainous regions and shield areas.
