due to the chemical changes and climate change.
- Marble - Schist - Gniess - Slate - Quartzite
Metamorphic.
gniess, slate, and quartzite
The slate or slate changes into schist
Slate becomes schist

gneiss, schist, slate
Slate, after that it can continue to schist.
Phyllite is a foliated metamorphic rock that is texturally intermediate between slate and schist. It exhibits a greater degree of metamorphism than slate but not as much as schist, resulting in a medium-grain texture with a glossy sheen.
The process is called Metamorphosis of Rocks. When the slate goes under the conditions of high pressure and heat it changes to schist or gneiss. Type of slate decide whether it gonna be schist or gneiss.
Heat and pressure change shale into metamorphic rock, specifically slate when exposed to low to moderate levels of heat and pressure, and then further into phyllite, schist, and gneiss as the intensity of heat and pressure increases.
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
