what type of metamorphism is caused by igneous intrusions
Contact metamorphism occurs typically around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock.The area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole.etamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change).
