WebContact metamorphism is usually restricted to relatively shallow depths (low pressure) in the Earth because it is only at shallow depths where there will be a large contrast in temperature between the intruding magma and the surrounding country rock. WebContact metamorphism occurs locally, adjacent to igneous intrusions. It involves conditions of low to moderate pressure and intense heating. The intensity of contact metamorphism is greatest at the contact between parent rock and intrusive magma. The intensity then decreases rapidly over a short distance from the magma or hydrothermal fluids.
