Ocean-floor metamorphism is a type of metamorphism of regional or local extent related to the steep geothermal gradient occurring near spreading centres in oceanic environments. The recrystallisation, which is mostly incomplete, encompasses a wide range of temperatures. The metamorphism is associated with circulating hot aqueous fluids(with related metasomatism) and typically shows an increasing temperature of metamorphism with depth. 5, record 10, English, - ocean%2Dfloor%20metamorphism

During extension at mid-ocean ridges (red-orange), convection carries heat to very shallow levels, where 7-km thick oceanic crust forms; hydrothermal circulation produces low P/T metamorphism, often called seafloor metamorphism: Many good examples of seafloor metamorphism are known from ophiolites in the Sierra Nevada and Klamaths. 3, record 10, English, - ocean%2Dfloor%20metamorphism
