Clastic and organic sedimentary rocks like conglomerate, coal, some limestones, and shale, are formed under pressure from overlying sediments.
A clastic and/or organic sedimentary rock.
Clastic
Yes
Turn it into metamorphic rock.
extreme heat and pressure
metamorphic - formed when igneous or sedimentary rocks are put under extreme heat and/or pressure. igneous - volcanic rock (comes from a volcano) sedimentary - particles of rock/sand/shells/clay etc. 'gathered' to make a rock.
The rock you are referring to is shale. Shale is a fine-grained sedimentary rock composed of compacted clay and silt particles. When subjected to intense heat and pressure, shale can undergo metamorphism and transform into slate. This process of metamorphism causes the clay minerals in shale to recrystallize, resulting in the characteristic foliated texture of slate.
Excess pressure, extreme stress, and high temperature
Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.

Igneous or sedimentary rocks that have been transformed by heat or pressure are known as metamorphic rocks.
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.

Metamorphic rocks.
Normally when sedimentary rocks are squashed and heated they do indeed change, they become metamorphic rocks. e.g. mud will be turned into slate - limestone into marble etc.As the metamorphic temperature and pressure increase still further, most sedimentary rocks end up as Granulites or Banded Gneisses which look very much like igneous rocks (Granites).In the extreme, sedimentary rocks can melt, and these melts will form new magmas which will eventually harden to form new igneous rocks.
Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.
