No. Phyllite can metamorphose into schist and then into gneiss.
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
Not a mineral but a rock. Schist comes asfter phyllite ut before gneiss.
schist
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.
- Amphibolite - Eclogite - Gneiss - Greenstone - Hornfels - Marble - Migmatite - Phyllite - Quartzite (Metaquartzite) - Schist - Slate - Soapstone
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
Shale > Slate > Phyllite > Schist > Gneiss > Migmatite > Complete Melt
Pennsylvania is home to quartzite, slate, marble, phyllite, gneiss, and schist
"Foliated" rocks are usually metamorphic rocks like phyllite, slate, schist, and gneiss.
It can, indirectly. Shale is a sedimentary rock. Like many rocks, gneiss can be weathered down to very fine particles to the point that it becomes clay or silt. Those particles can then settle on the bottom of a body of water as mud. Under the pressure of burial, that mud can become shale. However, gneiss can also form from shale. Under long exposure to enormous heat and pressure shale will becomes slate, further heating and pressure will turn slate into phyllite, phyllite into schist, and schist into 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.
