Metamorphic Rocks Summary
... High pressure and low temperature metamorphism happens within a subducted plate of oceanic lithosphere, and in any sediment carried down by a subducting plate. Metasomatism due to hydrothermal solutions is linked to plate tectonics because the solutions tend to form in, or be associated with, strato ...
