Physical properties
Hardness: 6-7 Mohs; Color: Pink, reddish-brown, grey-white; Luster: Vitreous to dull; Crystal structure: Phaneritic (visible interlocking crystals); Cleavage: Perfect in feldspar grains.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface. High silica content causes the light color. Typically Precambrian to Cenozoic in age.
Uses & applications
Used extensively in construction, countertops, monuments, curbing, and as decorative gravel.
Geological facts
Granite is the most common igneous rock found on Earth's continental crust and makes up the core of many mountain ranges.
Field identification & locations
Identify in the field by its 'salt and pepper' appearance with pink/orange tints from potassium feldspar. Found in batholiths and continental shields globally.
