What is contact metamorphism

The contact of magma causes a sudden change in temperature of an existing rock.Sometimes the contact zone is measured in centimeters or millimeters!There, contrasts in temperature between country rock and.The metamorphosed zone around an igneous rock is known as the metamorphic aureole.Contact metamorphism is the name given to the changes that take place when magma is injected in the surrounding solid rock (country rock).

Contact metamorphism takes place where a body of magma intrudes into the upper part of the crust.Definition of contact metamorphism :Contact 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.This rapid rise in temperature causes the rock.280 and 420 °c, log f(o 2):−35 and−28].

Contact metamorphism is a type of metamorphism which occurs adjacent to intrusive igneous rocks due to an increase in temperature resulting from an intrusion of hot magma into the rock.Contact metamorphism is a type of metamorphism that occurs adjacent to intrusive igneous rocks due to temperature increases resulting from hot magma intrusion into the rock.Contact metamorphism occurs locally, at and near the contacts between intrusions and the surrounding country or host rock.Contact metamorphism is a type of metamorphism where rock minerals and texture are changed, mainly by heat, due to contact with magma.
