Melting is the process in the rock cycle that causes magma to form.
138Metamorphism is the isochemical process by which rocks are changed by either heat or pressure, or both heat and pressure. The chemical composition of the parent rock will be the same as the metamorphic rock produced.The rock undergoes the very slow process of solid-state recrystallisation without melting.ifferent temperatures and pressures cause new minerals to grow in rocks that have the same composition. The minerals produced are directly related to pressure and temperature conditions. The lower temperature limit for metamorphism is between 200 and 150 o C. Below these temperatures, changes are part of diagenesis.
