Physical properties
Hardness of 6-7 on the Mohs scale, composed mainly of quartz, alkali feldspar, and plagioclase. Features a phaneritic texture with pink, white, and dark grey or black mineral grains and a vitreous to dull luster.
Formation & geological history
Forms from the slow cooling and crystallization of silica-rich magma beneath the Earth's crust, typically over millions of years in continental tectonic settings.
Uses & applications
Widely used in construction for dimensional stone, floor tiles, countertops, and monumental architecture due to its exceptional durability and aesthetic appeal.
Geological facts
Granite is the most common intrusive rock on Earth's continents and forms the basement rock of many mountain ranges. Its name is derived from the Latin granum, meaning grain.
Field identification & locations
Easily identified by its visibly crystalline, speckled appearance featuring interlocked light and dark mineral crystals. Found globally in shield areas and mountainous regions.
