What causes granite to be transformed into gneiss how is sandstone transformed into quartzite.
What causes granite to be transformed into gneiss.
It is impossible for granite to turn into gneiss it is a scientific impossibility that cannot be done with only heat and pressure.
Which of the following is not one of the three major classes of rock.
The change from granite to gneiss is not mineralogical i e.
Granite gneiss can also form through the metamorphism of sedimentary.
Another important structural change is the development of foliation or linear appearance in a gneiss.
Compacting and cementing b.
What geologic process can change granite igneous rock into gneiss metamorphic rock.
It takes thousands of years for granite to cool.
Melting you answered correctly.
There are no chemical changes but structural.
Metamorphic rocks form from heat and pressure which changes the original or parent rock into a completely new rock.
More fleshed out fuller and still correct answer.
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.
Short succinct and correct answer.
These rocks primarily consist of quartz feldspar and mica.
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.
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.
Plate tectonics typically subduction force basaltic magmas to rise beneath the continents.
Heat and pressure d.
Heat and pressure cause granite to become gneiss and change sandstone into quartzite.
Add heat to this process and magmas release co2 and water that help melt rocks.
As the basalt releases heat and fluids large chunks of continental curst have the potential to transform into granite.
Sedimentary you answered correctly.
Gneiss is a metamorphic rock granite is an igneous rock and sandstone is a sedimentary rock.
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.
All rocks undergo a series of processes called the rock cycle where one type of rock changes into another.
The appearance of granular minerals is what marks the transition into gneiss.
