This type of metamorphism happens beneath slowly subsiding sedimentary basins and in addition during the descending oceanic plate in certain subduction zones. The latter procedure takes place either when incredibly hot magma intrudes and alters the thermal state of the stationary rock or once the rock is speedily transported by tectonic processes (e.g., thrust faulting or substantial-scale folding) into a new depth-temperature regime in, such as, areas of collision amongst two continents (
