Is granite a mineral or rock. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. It comprises some of the oldest known rocks on earth and is the most abundant basement rock underlying the relatively thin sedimentary rock cover of the continents. In reference to the coarse grained structure of such a holocrystalline rock the word granite comes from the latin granum a grain. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.

Granite is the most widespread of igneous rocks underlying much of the continental crust. Granite is an intrusive igneous rock. Granites depending on their mineralogy can be predominantly white pink or gray in colour. Intrusive rocks form from molten material magma that flows and solidifies underground where magma cools slowly.

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. Biotite may occur in granite of any type and is usually present though sometimes in very small amounts. Granite is a coarse grained light colored igneous rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. Granite is a grained igneous rock that is formed when magma cools and deep within the earth s crust therefore it is an structure.

Granite is a common type of granular and phaneritic felsic intrusive igneous rock. Granites can be predominantly white pink or gray in color depending on their mineralogy. This simple definition enables students to easily identify the rock based upon a visual inspection. More than that granite is the signature rock of the planet earth itself.

Generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm. Eventually the overlying rocks are removed exposing the granite. The minor essential minerals of granite may include muscovite biotite amphibole or pyroxene. 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.

Granite ˈɡrænɪt is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granite is a felsic generally equigranular relatively light coloured intrusive rock. It is coarse to medium grained.
