The Process Of Granite Formation

Each rock has a unique formation process.

The process of granite formation. Granite is actually made up of several different minerals including feldspar and quartz. The name appeared for the first time in works of the english botanists physician and philosopher caesalpinus in the 16th century. Many mineral deposits form near crystallizing granite bodies from the hydrothermal solutions that such bodies release. The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks.

Formation of granite is explained below. To form granite magma must first cool underground. This is an extremely slow process. Granite crystallizes from silica rich magmas that are miles deep in earth s crust.

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. They are crystallized by felsic melts that are less dense than mafia rocks and therefore tend to ascend to the surface. Since the time required to form granite is rather long it is both a strong and valuable stone. The decaying material releases a significant amount of heat which melts the rocks around it.

Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Granite is more common in continental crust than in oceanic crust and has a felsic composition.
