This is an extremely slow process.
The process of granite formation.
The name appeared for the first time in works of the english botanists physician and philosopher caesalpinus in the 16th century.
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 is actually made up of several different minerals including feldspar and quartz.
Since the time required to form granite is rather long it is both a strong and valuable stone.
The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other 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.
Each rock has a unique formation process.
Formation of granite is explained below.
The decaying material releases a significant amount of heat which melts the rocks around it.
Granite is more common in continental crust than in oceanic crust and has a felsic composition.
They are crystallized by felsic melts that are less dense than mafia rocks and therefore tend to ascend to the surface.
To form granite magma must first cool underground.
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.
