The minor essential minerals of granite may include muscovite, biotite, amphibole, or pyroxene. Igneous rocks contain randomly arranged interlocking crystals, which will vary depending on how quickly the molten magma has cooled and solidified. These result in I-type granitoids, derived from igneous protoliths and containing moderate amounts of Al2O3 and high amounts of Na2O, and S-type granitoids, derived from sedimentary protoliths and containing high amounts of Al2O3 and relatively low amounts of Na2O. Granite is the most widespread of igneous rocks, underlying much of the continental crust. Rocks containing less than 20 percent quartz are almost never named granite, and rocks containing more than 20 percent (by volume) of dark, or ferromagnesian, minerals are also seldom called granite.

Chappell and W. E. Stephens ABSTRACT: I-type granites are produced by partial melting of older igneous rocks that are metaluminous and hence have not undergone any significant amount of chemical weathering. The product meets Cal Trans Section 68-1 for permeable products. Same rock type may have significantly different shear strength parameters depending upon site-specific geological characteristics. Gneiss (/ ˈ n aɪ s /) is a common and widely distributed type of metamorphic rock.Gneiss is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks.Orthogneiss is gneiss derived from igneous rock (such as granite).

Because of its use as paving block and as a building stone, the quarrying of granite was, at one time, a major industrial activity. Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components and alkali feldspar accounts for 65 to 90 percent of the total feldspar content. The melted sediments would have produced magma intermediatein it… Porphyry. Some granite is the oldest known rock on earth.
