How does hydrothermal metamorphism occur
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. WebMar 15, 2024 · Metamorphism can occur either when a rock moves from one position to another along a single geotherm or when the geotherm itself changes form. The former can take place when a rock is buried or uplifted at a rate that permits it to maintain thermal equilibrium with its surroundings.
