It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Some rocks such as limestone or quartzite are composed primarily of one mineral calcite or aragonite in the case of limestone and quartz in the latter case.

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. Most rocks are aggregates of minerals.

Additionally the quartz and feldspar that compose it are harder than steel. Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. Other rocks can be defined by relative abundances of key essential minerals. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.

The minerals that make up granite give it the unique colors we see in different types of granite. A rock is an aggregate of one or more minerals or mineraloids. 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.
