Question

Quizplus · Accepted Answer

Hydrothermal metamorphism is most commonly found along the axis of mid-ocean ridge systems, where hot fluids are released from magma chambers and react with the surrounding rocks, causing metamorphism. In subduction zones and transform plate boundaries, the focus is on tectonic deformation rather than hydrothermal alterations. While mantle plumes can cause melting and metamorphism in the continental plates, it is not as widespread as at mid-ocean ridges.
