What geologic process can change granite into gneiss.

Can granite become gneiss.

If the chemistry and conditions are right granite forming minerals can precipitate. The view shown in the photo is about 12 inches across. The end product of their metamorphism is a banded rock with a mineralogical composition like granite. Minerals are seen arranged in bands in gneiss.

By heat or pressure sometimes both. Gneiss is a metamorphic rock created by applying heat and pressure to a number of different rocks including shale and granite. The change from granite to gneiss is not mineralogical i e. Granite turns into gneiss.

Granite is an intrusive igneous rock meaning that it forms from magma below the earth s surface. Granite gneiss can also form through the metamorphism of sedimentary rocks. There are no chemical changes but structural. If this occurs it will now be classified as a granite.

Paragneiss is gneiss derived from sedimentary rock such as sandstone. Not all gneiss is obtained from granite and there are also diorite gneiss biotite gneiss garnet gneiss and so on. Another important structural change is the development of foliation or linear appearance in a gneiss. This is due to the long minerals in the original granite lining up perpendicular to a regional stress field.

When subjected to intense heat and pressure granite will. Granite becomes gneiss after the process of metamorphism well gneiss dosent turn into granite. Gneiss can turn into an igneous rock if it is melted. The variety of colors found in gneiss closely resembles the color.
