Granite (Rock)

Picture of Granite Rock

Granite is a common type of intrusive igneous rock that is granular and phaneritic in texture. 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. Granite is an igneous rock with between 20% and 60% Quartz by volume and at least 35% of the total feldspar. Granite countertops have been popular for decades as well as for sculptures, memorials, buildings, and other engineering projects.
