Is Granite Metamorphic Or Igneous

It is usually composed primarily of the minerals quartz feldspar and mica.

Is granite metamorphic or igneous.

It forms by the solidification of bodies of magma relatively deep below the surface. It forms from the slow crystallization of magma below earth s surface. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granite type rocks granitoids are abo.

Granite is a light colored igneous rock with grains large enough to be visible with the unaided eye. When granite is subjected to intense heat and pressure it changes into a metamorphic rock called gneiss. This evidence suggests that some granite is not igneous in origin but metamorphic. Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage.

Originally granite was thought to form mainly from magmatic differentiation of basaltic magma but geologists now believe there is simply too much of it for it to have formed this way except locally. There are similarities between the two types of rocks confusing many people. Granite is an igneous rock while gneiss is a rock that may have been igneous or sedimentary earlier but has undergone metamorphic process. It is an intrusive igneous rock.

The key difference between igneous rocks and metamorphic rocks is that igneous rocks are the oldest rocks on earth while metamorphic rocks are derivatives of igneous rocks and sedimentary rocks.

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. Debate has long centered on whether granite is igneous or metamorphic in origin. Image via georgia state university. The types of rock.
