The descending of rock layers at subduction zones causes metamorphism in two ways; the shearing effect of the plates sliding past each other causes the rocks coming in contact with the descending rocks to change. Some of the descending rock will melt because of this friction.
Alteration of the minerals, textures, and composition of a rock that is caused by exposure to severe heat, pressure, and chemical actions. Metamorphism occurs to rocks at convergent plate boundaries, rocks that have been deeply buried, and rocks that have been contacted by migrating magma or hydrothermal fluids.lteration of the minerals, textures, and composition of a rock that is caused by exposure to severe heat, pressure, and chemical actions.
