A Metamorphic Rock Formed From Granite Is

Necessary for metamorphism comes from magma of the earth or friction from moving tectonic plates.

A metamorphic rock formed from granite is.

Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. They are not made from molten rock rocks that do melt form igneous rocks instead. A photograph of polished gneiss from the stock of a countertop vendor. 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. Granite is not metamorphic but an intrusive igneous rock formed from cooling magma. These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks.

Granite gneiss can also form through the metamorphism of sedimentary rocks. If there is too much heat or pressure the rock will melt and become magma. In other words if it formed from a rock that held basalt in it the rock has basalt in. Metamorphic rocks are an important topic in geology.

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. In migmatite you can see metamorphic rock that has reached the limits of metamorphism and begun transitioning into the igneous stage of the rock cycle by melting to form magma. In order to create metamorphic rock it is vital that the existing rock remain solid and not melt. This will result in the formation of an igneous rock not a metamorphic rock.

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. Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. A metamorphic rock formed from granite. The end product of their metamorphism is a banded rock with a mineralogical composition like granite.
