Physical properties
Hardness of 6 on the Mohs scale with a phaneritic, coarse-grained texture. Composed mainly of quartz, alkali feldspar, and plagioclase with a dull to vitreous luster.
Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years. It is a fundamental component of continental crust.
Uses & applications
Widely used in construction, architectural facings, monuments, and countertops due to its high durability.
Geological facts
Granite is the most common intrusive rock on Earth and forms the core of many major mountain ranges. Its name is derived from the Latin granum, meaning grain.
Field identification & locations
Identified easily by its visible interlocking crystals of quartz, pink or white feldspar, and dark biotite mica. It is found globally in ancient shields and mountain belts.
