The Formation Of Granite

Strictly speaking granite is an.

The formation of granite.

It forms from the slow crystallization of magma below earth s surface. Granite is a common type of granular and phaneritic felsic intrusive igneous rock. Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock generally the slower the molten rock cooled the larger it s mineral crystals with k feldspar megacrysts forming in special circumstances greater than 5cm. More than that granite is the signature rock of the planet earth itself.

During its formation mineral gases and liquids create crystalline formations giving it a stunning array of colors. There are a variety of granite uses and the granite reserves are found in many countries around the world. Learn more about the properties and uses of granite in this article. An igneous rock of volcanic origin granite is one of the hardest natural stones.

Granite formation took place millions of years ago. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. The other rocky planets mercury venus and mars are covered with basalt as is the ocean floor of earth but only earth has this beautiful and interesting rock type in abundance. Granites depending on their mineralogy can be predominantly white pink or gray in colour.

It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Granite is composed mainly of quartz and feldspar with minor amounts of mica amphiboles and other minerals this mineral composition usually gives granite a red pink gray or white color with dark mineral. The rocks in the earth s crust continuously undergo changes in their composition which leads to formation of other rocks. Granite is the signature rock of the continents.

Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Each rock has a unique formation process. Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.
