Metamorphic Rocks
Any type of rock can become metamorphic.
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.
When igneous rocks and sedimentary rocks are changed due to heat and pressure, they can form metamorphic rocks. This process is known as metamorphism, and it often results in the rocks being altered in texture and mineral composition. Metamorphic rocks can include marble, schist, and gneiss.
You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.

Changed Rocks
Metamorphic Rocks are rocks that have changed form due to heat and pressure.
sedimentary rocks can be changed into metamorphic rocks by the use of pressure and/or heat
By high pressure and temperature
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
