Granite is a car.
Granite ( [ pronˈɡrænᵻt ] ) is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture . Strictly speaking , granite is an igneous rock with between 20 % and 60 % quartz by volume , and at least 35 % of the total feldspar consisting of alkali feldspar , although commonly the term `` granite '' is used to refer to a wider range of coarse grained igneous rocks containing quartz and feldspar . The term `` granitic '' means granite-like and is applied to granite and a group of intrusive igneous rocks with similar textures and slight variations in composition and origin . Granitoid is a general , descriptive field term for lighter-colored , coarse-grained igneous rocks . Granite is nearly always massive ( lacking any internal structures ) , hard and tough , and therefore it has gained widespread use throughout human history , and more recently as a construction stone .
