It is widely accepted that the formation of Granite occurs when molten rock under pressure solidifies. However there is evidence to support other methods for the formation of this substance. Lack of evidence for contact between the granite and surrounding stone, as well as evidence of sediments may demonstrate that granite can also form through metamorphic processes, by combining, under pressure several other minerals.
It is made mostly from quartz and feldspar, and is formed deep below the surface of the earth. Granite makes up most of the earths crust, and is generally revealed to the surface when continental shifts cause breaks in the landscape that allow it to be seen.
Granite is generally soft in color, although feldspar can cause it to take on darker grey or pink hues. It is a relatively light stone; however it has a high durability and strength.
Granite is widely used in flooring and counter tops. It has a very “rustic” feel and can add to a room’s decor in an understated way. Granite can also be crafted into house wares, or used as sidings. It has been a popular material in the formation of homes and buildings since ancient times. Its strength made it useful in defensive building settings.
