Physical properties
Hardness: 6-7 Mohs; Color: Pink, reddish-brown, white, and gray; Luster: Vitreous to dull; Structure: Phaneritic (coarse-grained); Specific Gravity: 2.63-2.75
Formation & geological history
Formed by the slow cooling and solidification of magma beneath the Earth's surface. High potassium feldspar content gives it the pink hue. Common in continental crust and mountain ranges.
Uses & applications
Extensively used in construction for countertops, floor tiles, paving stones, and monuments due to its durability and aesthetic appeal.
Geological facts
Granite makes up a large part of the continental crust. The pink color is specifically due to the presence of Orthoclase (alkali feldspar).
Field identification & locations
Identify by its interlocking crystalline texture and lack of foliation. Found globally in batholiths and eroded mountain shields. Granite will scratch glass easily.
