A Metamorphic Rock Formed From Granite Is

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.

A metamorphic rock formed from granite is.

Metamorphic rocks change when exposed to even more heat and pressure. Consider how granite changes form. Actually it truly depends on the type of rock the metamorphic rock formed from. If there is too much heat or pressure the rock will melt and become magma.

Some form during mountain building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Necessary for metamorphism comes from magma of the earth or friction from moving tectonic plates.

Granite is not metamorphic but an intrusive igneous rock formed from cooling magma. The original rock is subjected to heat temperatures greater than 150 to 200 c and pressure 100 megapascals 1 000 bar or more causing profound physical or chemical change the protolith may be a sedimentary igneous or existing metamorphic rock. They are not made from molten rock rocks that do melt form igneous rocks instead. A metamorphic rock formed from granite.

Granite gneiss can also form through the metamorphism of sedimentary rocks. The granitic rock in migmatite probably originated from partial melting of some of the metamorphic rock though in some migmatites the granite may have intruded the rock from deeper in the crust. Metamorphic rocks are an important topic in geology. A photograph of polished gneiss from the stock of a countertop vendor.

In order to create metamorphic rock it is vital that the existing rock remain solid and not melt. The end product of their metamorphism is a banded rock with a mineralogical composition like granite. In other words if it formed from a rock that held basalt in it the rock has basalt in. Metamorphic rocks are formed from other rocks that are changed because of heat or pressure.
