What mineral is more common than granite. Other common minerals include mica muscovite and biotite and hornblende see amphibole. It forms from the slow crystallization of magma below earth s surface. Some granites contain around 10 to 20 parts per million ppm of uranium. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.

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. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Granite is a natural source of radiation like most natural stones. 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.

It consists of coarse grains of quartz 10 50 potassium feldspar and sodium feldspar. Granite is a light colored plutonic rock found throughout the continental crust most commonly in mountainous areas. Potassium 40 is a radioactive isotope of weak emission and a constituent of alkali feldspar which in turn is a common component of granitic rocks more abundant in alkali feldspar granite and syenites.
