Phyllite is metamorphosed slate, which is also a metamorphic rock. Shale or mudstone is the protolith (parent rock) of slate.
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
The most usual protolith of slate is the sedimentary rock shale.
It becomes a metamorphic rock. Sandstone can metamorphose into quartzite. Limestone can metamorphose into marble. Shale can metamorphose into slate.
