Physical properties
Phaneritic (coarse-grained) texture; Mohs hardness 6-7; contains pink potassium feldspar (orthoclase), translucent quartz, and dark biotite or hornblende; dull to vitreous luster.
Formation & geological history
Formed from the slow cooling of silica-rich magma deep underground. This allows large crystals to grow. Most granites date from the Precambrian to Cenozoic eras.
Uses & applications
Extensively used in construction for countertops, floor tiles, paving stones, monuments, and as crushed stone for road base.
Geological facts
Granite makes up a large portion of the Earth's continental crust. The pink color is specifically due to a high concentration of potassium-rich feldspar.
Field identification & locations
Identify by its salt-and-pepper look with pink/orange highlights and visible crystalline grains. Found globally in mountainous regions or areas where ancient crust is exposed.
