How do metamorphic rocks form under heat and pressure?
GeologyRock cycle
Quick Answer
Existing rocks are changed deep underground without fully melting. Heat, pressure, and fluids rearrange minerals into new textures and mineral combinations.
The Full Story
Metamorphic rocks begin as igneous, sedimentary, or older metamorphic rocks that are buried or squeezed deep within Earth. As temperatures rise and pressure increases, minerals become unstable and recrystallize into new forms. Fluids can speed the process by moving ions through the rock. Common examples include shale turning into slate and limestone changing into marble.
Key Facts
1.Metamorphism changes rock without complete melting
