Submarine thermal springs mainly occur in modern mid-ocean ridges, back-arc basins, and submarine volcanic island arcs [ 80 ]. WebSeafloor (Hydrothermal) Metamorphism At an oceanic spreading ridge, recently formed oceanic crust of gabbro and basalt is slowly moving away from the plate boundary (Figure 6.26). Water within the crust is forced to rise in the area close to the source of volcanic heat, drawing in more water from further away.
