Since the time required to form granite is rather long it is both a strong and valuable stone.
The process of granite formation.
This is an extremely slow process.
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.
Granite is actually made up of several different minerals including feldspar and quartz.
Granite is formed by the solidification of magma under the earth s surface.
The decaying material releases a significant amount of heat which melts the rocks around it.
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.
To form granite magma must first cool underground.
Granite crystallizes from silica rich magmas that are miles deep in earth s crust.
Generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm.
Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock.
Each rock has a unique formation process.
Granite is more common in continental crust than in oceanic crust and has a felsic composition.
Granite is an intrusive igneous rock which is very hard crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.
