WebAll of these factors vary widely and result in different types of metamorphism depending upon which factor is dominant. The three main types of metamorphism are: Contact (also known as thermal) metamorphism: this is produced by high temperature, low pressure, low strain and variable fluid pressure. It is normally produced by igneous rocks such ... WebAt shallow depths within the crust (usually less than 6 km) the heat sources responsible for contact metamorphism are bodies of hot magma (e.g. igneous intrusions) which raise the temperature of the surrounding rocks. These thermal affects are usually restricted to the contact zones of the intrusions, hence the term contact metamorphism. the maamtrasna murders

Metamorphism refers to changes to rocks that take place in the Earth's interior.

WebThis type of metamorphism is often found at convergent plate boundaries. Contact metamorphism occurs over a small area of a few feet to several square miles and is usually the result from the heat of intruding magma “cooking” the surrounding relatively cool country rock. Contact metamorphism usually occurs near the Earth’s surface. Metamorphic … 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).
