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.

Consider how granite changes form. Metamorphic rocks are an important topic in geology. If there is too much heat or pressure the rock will melt and become magma. Granite gneiss can also form through the metamorphism of sedimentary rocks.

These are the rocks that form by the effects of heat pressure and shear upon igneous and sedimentary rocks. Granite is not metamorphic but an intrusive igneous rock formed from cooling magma. A metamorphic rock formed from granite. Metamorphic rocks change when exposed to even more heat and pressure.

Necessary for metamorphism comes from magma of the earth or friction from moving tectonic plates. They are not made from molten rock rocks that do melt form igneous rocks instead. 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 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. Metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form. Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. 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.

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. Actually it truly depends on the type of rock the metamorphic rock formed from.
