Phyllite is metamorphosed slate, which is also a metamorphic rock. Shale or mudstone is the protolith (parent rock) of slate.
phyllite
If slate is sufficiently heated and compressed it becomes phyllite.
Phyllite is a metamorphic rock.
Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.

Phyllite is a metamorphic rock.
The parent rock or protolith of phyllite is slate.
No. Phyllite can metamorphose into schist and then into gneiss.
Shale and granite are sedimentary rocks. After thousands of years under pressure and heat, they can turn into phyllite rock.
The degree of metamorphism. Phyllite is slate further metamorphosed.
Phyllite is a foliated metamorphic rock whose parent rock is slate.
