Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite is generally light colored in shades of white, grey, or pink. Minerals are mostly quartz and feldspar, with small amounts of mica. Granite is nearly always massive, hard and tough, and therefore it has gained widespread use as a construction stone. The average density of granite is 2.75 g/cm3 and its viscosity at standard temperature and pressure is~4.5 • 1019 Pa•s.
Granite has been extensively used as a dimension stone and as flooring tiles in public and commercial buildings and monuments. Because of its abundance, granite was commonly used to build foundations for homes in New England. With increasing amounts of acid rain in parts of the world, granite has begun to supplant marble as a monument material, since it is much more durable. The Granite Railway, America’s first railroad, was built to haul granite from the quarries in Quincy, Massachusetts, to the Neponset River in the 1820s. Polished granite is also a popular choice for kitchen countertops due to its high durability and aesthetic qualities. In some areas granite is used for gravestones and memorials. Granite is a hard stone and requires skill to carve by hand. Engineers have traditionally used polished granite surfaces to establish a plane of reference, since they are relatively impervious and inflexible.
