Physical properties
Hardness: 6-7 on Mohs scale; Color: Pink, white, gray, black mottled pattern; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained, interlocking crystals of quartz, feldspar, and mica).
Formation & geological history
Formed by the slow crystallization of magma below Earth's surface in continental crustal environments over millions of years.
Uses & applications
Extensively used as building material, polished kitchen countertops, floor tiles, paving stones, and outdoor monuments.
Geological facts
Granite makes up a large portion of Earth's continental crust. It is exceptionally durable and heat-resistant, which makes it ideal for kitchen countertops.
Field identification & locations
Identified by its distinctive speckled appearance consisting of visible interlocking quartz, feldspar, and biotite/amphibole grains. Highly abundant worldwide.
