Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
Slate forms from shale (or other rocks composed primarily of clay minerals) due to low grade metamorphism.
Shale is not metamorphic. It is a sedimentary rock formed from clay or silt.
Forms from the rock cycle, the process is called compaction
Shale
Shale can metamorphose into slate, which can metamorphose into phyllite, which can metamorphose into schist, which can metamorphose into gneiss.
shale → slate → phyllite → schist → gneiss
No. Shale is the most common sedimentary rock exposed on the surface of Earth.
Slate is metamorphosed shale.
The first metamorphic rock to form from shale is slate. With further metamorphosis you get phyllite, then schist, then gneiss.

As you increase the temperature and pressure of Shale it metamorphism occurs. It changes in this order: Shale > Slate > Phyllite > Schist > Gneiss > Migmatite
Shale.
under heat and pressure
Slate, after that it can continue to schist.
Shale > Slate > Phyllite > Schist > Gneiss > Migmatite > Complete Melt
Shale is the only sedimentary rock which can be changed into schist.
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
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.
yes, it's slate. it goes from shale to slate to phyllite to mica schist.
