Physical properties
Hardness of 6 on the Mohs scale, typically pink, white, gray, or red with speckled mineral grains. Luster is dull to vitreous. Phaneritic (coarse-grained) crystal structure with visible interlocking crystals of quartz, feldspar, and mica.
Formation & geological history
Formed from the slow cooling and solidification of magma rich in silica and alkali metal oxides beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural buildings, monuments, countertops, paving stones, and interior design.
Geological facts
Granite is the most common rock of the Earth's continental crust and is exceptionally durable against weathering.
Field identification & locations
Easily identified by its distinctive speckled appearance and visible interlocking crystals. Found globally in mountainous regions and shield areas.
