Physical properties
Hardness of 6 on the Mohs scale, phaneritic texture with visible interlocking mineral grains, and a vitreous to dull luster. Composed primarily of quartz, alkali feldspar, and plagioclase with minor dark minerals like biotite.
Formation & geological history
Formed from the slow cooling and crystallization of silica-rich magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction for dimensional stone, floor tiles, countertops, and monuments due to its high durability.
Geological facts
Granite is the most common intrusive rock in the Earth's continental crust and is characteristic of continental shield areas.
Field identification & locations
