Four rocks formed by metamorphic grade are slate, phyllite, schist and gneiss. Slate and pnyllite are low grade; schist is a medium grade; and gneiss is a high grade rock.
Shale > Slate > Phyllite > Schist > Gneiss > Migmatite > Complete Melt
Yes, additional pressure and heat will lead to further metamorphism. The reference used to describe this is called the 'degree of metamorphism'. For instance, the sedimentary rock shale can become the low grade metamorphic rock slate. In the next degree of metamorphism, slate can become phyllite. Phyllite can then become schist, and finally gneiss. Migmatite is the highest grade metamorphic rock, but has been partially melted.
Texture and metamorphic grade. Schist has visible crystals, while phyllite has crystals too small to be seen with the eye or barely seen. This is a result of schist having higher grade metamorphism.
Gneiss
As you increase the temperature and pressure of Shale it metamorphism occurs. It changes in this order: Shale > Slate > Phyllite > Schist > Gneiss > Migmatite
No. Phyllite can metamorphose into schist and then into gneiss.

Pennsylvania is home to quartzite, slate, marble, phyllite, gneiss, and schist
"Foliated" rocks are usually metamorphic rocks like phyllite, slate, schist, and gneiss.
No, but slate and gneiss are both a type of metamorphic rock. Slate will also turn into Gneiss, eventually, if metamorphosing continues. The series is Shale (sedimentary) >> Slate (metamorphic) >> Phyllite >> Schist >> Gneiss
The first metamorphic rock to form from shale is slate. With further metamorphosis you get phyllite, then schist, then gneiss.
Slate, gneiss, skarn, phyllite, hornfels, amphibolite, schist, quartzite, marble, and granulite are all metamorphic rocks.
Not a mineral but a rock. Schist comes asfter phyllite ut before gneiss.
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
Slate, gneiss, skarn, phyllite, amphibolite, schist, quartzite, marble, and granulite are all metamorphic rocks.
