What Causes Granite To Be Transformed Into Gneiss

Which of the following is not one of the three major classes of rock.

What causes granite to be transformed into gneiss.

The appearance of granular minerals is what marks the transition into gneiss. All rocks undergo a series of processes called the rock cycle where one type of rock changes into another. It is impossible for granite to turn into gneiss it is a scientific impossibility that cannot be done with only heat and pressure. More fleshed out fuller and still correct answer.

Heat and pressure d. Sedimentary you answered correctly. Add heat to this process and magmas release co2 and water that help melt rocks. It takes thousands of years for granite to cool.

There are no chemical changes but structural. Compacting and cementing b. What causes granite to be transformed into gneiss. Gneiss gneiss is a high grade metamorphic rock meaning that it has been subjected to higher temperatures and pressures than schist it is formed by the metamorphosis of granite or sedimentary rock.

Intense heat and pressure can also metamorphose granite into a banded rock known as granite gneiss this transformation is usually more of a structural change than a mineralogical transformation. These rocks primarily consist of quartz feldspar and mica. Heat and pressure cause granite to become gneiss and change. This is due to the long minerals in the original granite lining up perpendicular to a regional stress field.

Heat and pressure cause granite to become gneiss and change sandstone into quartzite. What causes granite to be transformed into gneiss how is sandstone transformed into quartzite. Another important structural change is the development of foliation or linear appearance in a gneiss. The change from granite to gneiss is not mineralogical i e.

When subjected to intense heat and pressure granite will. What geologic process can change granite igneous rock into gneiss metamorphic rock. Granite gneiss can also form through the metamorphism of sedimentary. Melting you answered correctly.

Gneiss is a metamorphic rock granite is an igneous rock and sandstone is a sedimentary rock. As the basalt releases heat and fluids large chunks of continental curst have the potential to transform into granite. Gneiss displays distinct foliation representing alternating layers composed of different minerals however unlike slate and schist gneiss does not preferentially break along planes of foliation. With pictures porcelain is a very hard translucent white ceramic that has been manufactured in china since the 600s and in europe since the 1700s.
