The Process Of Granite Formation

Granite is actually made up of several different minerals including feldspar and quartz.

The process of granite formation.

Granite is an intrusive igneous rock which is very hard crystalline and is visibly homogeneous in texture and forms by melting of continental rocks. Generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm. This is an extremely slow process. The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks.

To form granite magma must first cool underground. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Granite is formed by the solidification of magma under the earth s surface. Granite crystallizes from silica rich magmas that are miles deep in earth s crust.

Each rock has a unique formation process. Many mineral deposits form near crystallizing granite bodies from the hydrothermal solutions that such bodies release. The decaying material releases a significant amount of heat which melts the rocks around it. Since the time required to form granite is rather long it is both a strong and valuable stone.

They are crystallized by felsic melts that are less dense than mafia rocks and therefore tend to ascend to the surface. Granite s formation inside the earth below what is known as the mantle layer is a layer of molten rock formed by radioactive elements that occur naturally as the ground breaks down and decays.
