Physical properties
Hardness: 6-7 Mohs; Color: Pink, salmon, or reddish-brown with grey/white/black flecks; Luster: Dull to vitreous; Crystal Structure: Phaneritic (coarse-grained coarse crystals); Cleavage: Indistinct; Specific Gravity: 2.63-2.75
Formation & geological history
Formed from the slow crystallization of silica-rich magma below the Earth's surface (intrusive). The pink color is caused by the presence of abundant potassium feldspar (orthoclase).
Uses & applications
Extensively used in construction for countertops, floor tiles, paving stones, monuments, and as a decorative stone in architecture due to its durability.
Geological facts
Granite is one of the hardest substances in the world and makes up a heavy portion of the Earth's continental crust. El Capitan in Yosemite is a famous granite monolith.
Field identification & locations
Identify by its coarse, interlocking crystalline texture containing pink feldspar, glassy quartz, and dark biotite or hornblende. Commonly found in mountainous regions or shield areas like the Canadian Shield.
