Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granite is a strong stone because its mineral grains have grown tightly together during a very slow cooling period. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye.

It forms from the slow crystallization of magma below earth s surface. Granite is high in quartz about 25 feldspar and mica.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. This makes granite desirable for buildings and ornamental purposes such as gravestones and monuments. Granite is the most common intrusive rock in earth s continental crust it is familiar as a mottled pink white gray and black ornamental stone it is coarse to medium grained. Over 40 of dimension stone quarried is granite.

Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
