Physical properties
Hardness of 6 on the Mohs scale, typically colored grey, pink, or white with a speckled appearance due to interlocking mineral crystals. Luster is dull to vitreous. Composed mainly of quartz, alkali feldspar, and plagioclase.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, commonly associated with continental crust.
Uses & applications
Widely used in construction, architectural facades, countertops, monuments, and paving stones.
Geological facts
Granite makes up a major part of continental crusts and is one of the most durable natural building materials known.
Field identification & locations
Easily identified by its distinct phaneritic (coarse-grained) texture showing visible interlocking mineral grains. Found globally in mountainous regions and shield areas.
