In contact metamorphism there is
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. WebTypes of Metamorphism 1 Contact (thermal) • Due to heat from magma invading host rock. • Creates zoned bands of alteration in host rock. – Called a contact (or metamorphic) aureole. – The aureole surrounds the plutonic intrusion. • Zoned from high (near pluton) to low grade (far from pluton).
