What group of rock does slate belong?
Slate is a low-grade metamorphic rock.
What is graphite schist?
It is a medium-grade metamorphic rock with a preponderance of the platy mineral graphite.
What is the metamorphic grade of gneiss?
Gneiss is usually considered a high grade metamorphic rock (although there are some weird exceptions).
How does a metamorphic rock turn into another type of metamorphic rock?
From increased pressure and/or heat. Fluid removal results in hydrous mineral destruction and non-hydrous mineral creation, resulting in rock of a different mineralogy. A metamorphic rock can be further metamorphosed by additional heat and/or pressure into a rock with a higher degree of metamorphism. An example of this would be the metamorphic rock slate changing into the metamorphic rock phyllite.
How do you classify metamorphic rocks?
Metamorphic rocks are classified as being foliated or being non-foliated. Foliated metamorphic rocks have visible banding or sheet-like layering. Slate, phyllite, gneiss, and schist are foliated metamorphic rocks. Non-foliated metamorphic rocks do not display banding or layering. Marble and quartzite are non-foliated metamorphic rocks. Metamorphic rocks can also be classified as either regional metamorphic rocks or contact metamorphic rocks, depending on their method of formation.

Does metamorphic rock change?
Metamorphic rock can undergo a series of changes called degrees of metamorphism, from low-grade to high-grade.
Which low-grade metamorphic rock comosed of extremely fine sized mica and other mineral grains typically exhibits well -developed rock cleavage?
It is schist.

What is a metamorphic rock formed from a shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
What type of metamorphism would result in a schist?
Most schists are derived from phyllite, a lower grade metamorphic rock.
