This process is called metamorphism and it creates metamorphic rocks, such as marble.
When sedimentary rock is changed by heat and pressure, it forms metamorphic rock. This process is known as metamorphism, where the existing rock undergoes changes in mineral composition and texture without melting.
Metamorphism is the process where existing rocks are changed by heat, pressure, or fluids. This process causes the minerals in the rocks to rearrange and form new crystals, creating metamorphic rocks.
Your question contains part of the answer, 'metamorphic' rocks are the product of this process and the process is called Metamorphism - the solid-state recrystallization of pre-existing rocks as a result of changes in heat, pressure, and/or introduction of fluids.

Changed rocks are called metamorphic. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, through the use of heat and pressure.Metamorphic rocks
Sedimentary rock can be changed into metamorphic rock through the application of heat and pressure. This process typically occurs deep within the Earth's crust, where existing rocks are subjected to high temperatures and pressures that cause them to recrystallize and form new minerals.
regional metamorphism
Metamorphic rocks are formed when existing rocks undergo heat, pressure, and/or chemically active fluids, leading to changes in mineral composition or texture. This process does not involve melting of the rock, but rather the recrystallization of minerals due to high temperatures and pressures within the Earth's crust.
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
Metamorphic, changed by pressure and heat
The rock that has been changed by extreme pressure or heat is called metamorphic rock. It can form from igneous, sedimentary, or existing metamorphic rocks that undergo changes in temperature and pressure deep within the Earth's crust. Examples of metamorphic rocks include marble, slate, and gneiss.
