Physical properties
Hardness: 6-7 (Mohs); Color: Pink, reddish-gray, black; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained); Specific gravity: 2.63–2.75
Formation & geological history
Formed by the slow crystallization of magma below Earth's surface. High in silica and alkali metal oxides. Commonly found in continental crust and mountain ranges from various geological eras.
Uses & applications
Extensively used in construction, countertops, monuments, paving, and as decorative crushed stone.
Geological facts
Granite is the most common rock in the Earth's continental crust. The pink color specifically comes from a high concentration of potassium feldspar (orthoclase).
Field identification & locations
Identify by its interlocking granular texture where grains are visible to the naked eye. Look for a mix of light-colored minerals (quartz/feldspar) and dark minerals (biotite/amphibole). Found globally in cratons.
