Sedimentary or igneous rocks can be considered the parent rocks for metamorphic rocks. Although an existing metamorphic rock can be further metamorphosed or re-metamorphosed, metamorphic rock doesn’t normally qualify as a “parent rock”. WebbDuring metamorphism, the minerals in the protolith or the original rock will need to change. They need to equilibrate to the new temperature and pressure conditions to form new and stable minerals. This process transforms the protolith, which could be igneous, sedimentary, or metamorphic, into a new metamorphic rock. kw santa barbara
