Is granite a mineral.

Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both. It forms from the slow crystallization of magma below earth s surface. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. The crystals in granite provide a variety of mixed colors feldspar pink or red mica dark brown or black quartz clear pink white or black and amphibole black.

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 high in quartz about 25 feldspar and mica. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. 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 it is coarse to medium grained.
