Metamorphism which is caused from magma intrusion near the contact with the magma.
Mineralogical and textural changes and deformation of rock resulting from the head and pressure of a
Metamorphism of a rock near its contact with a magma.
Is the small scale metamorphic alteration of rock due to localized heating. It is usually cause by an igneous intrusion like a sill or a dyke.
Contact metamorphism refers to metamorphism resulting from the intrusion of magma which takes place at or near the contact point with the molten rock.
Mineralogical and textural changes and deformation of rock resulting from the heat and pressure of an igneous intrusion in the near vicinity.
Metamorphism genetically related to the intrusion (or extrusion) of magmas and taking place in rocks at or near their contact with a body of igneous rock.
Metamorphism of country rocks adjacent to an intrusion, caused by heat from the intrusion.
metamorphism resulting from high temperatures close to an intrusion of hot magma.
localized metamorphism resulting from the heat of an igneous intrusion.
