There are several different types of metamorphism that can occur: 1) Regional metamorphism – Widespread metamorphism due to strong tectonic forces 2) Contact metamorphism – Metamorphism due to an igneous intrusion into the country rock 3) Cataclastic metamorphism – High-pressure metamorphism found along a fault zone 4) Hydrothermal metamorphism – Metamorphism due to the movement of hot fluids through a rock 5) Burial metamorphism – Metamorphism of sedimentary rocks due to the build up of overlying sediments and rocks - most important
