shale
Shale is a sedimentary rock, not a metamorphic rock.
If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.
The result is a metamorphic rock. Metamorphic rocks form when existing rocks are subjected to high temperatures and pressures, causing them to recrystallize and change in mineral composition and texture. Examples include marble (from limestone) and slate (from shale).
Chlorite schist is a metamorphic rock. It forms from the metamorphism of rocks like shale or volcanic rocks under high temperature and pressure conditions, resulting in the growth of chlorite crystals within the rock.
Hornfels is a metamorphic rock that forms from the heat and pressure of tectonic processes acting on existing rocks such as shale, basalt, or sandstone. It is typically fine-grained and can have a variety of mineral compositions depending on the original rock type that underwent metamorphism.

A metamorphic rock.
The protolith of a metamorphic rock can be any pre-existing rock type, such as shale, limestone, basalt, or granite. The type of metamorphic rock that forms from a protolith depends on factors like temperature, pressure, and the mineral composition of the protolith.
If the mud has lithified into shale or mudstone, then metamorphosed, the answer would be slate.
Any type of rock, such as sandstone, shale, limestone, or granite, can be heated and squeezed under high pressure to transform into a metamorphic rock. The intensity of heat and pressure will determine the specific type of metamorphic rock that forms.

Metamorphic rocks
Phyllite is a type of metamorphic rock, not a mineral. It is formed from the metamorphism of shale or mudstone and has a fine-grained texture with a silky sheen due to the alignment of its minerals.
