The Formation Of Granite

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.

The formation of granite.

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 formation took place millions of years ago. Granite is a common type of granular and phaneritic felsic intrusive igneous rock. An igneous rock of volcanic origin granite is one of the hardest natural stones. 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.
