Compare contact thermal metamorphism and regional dynothermal metamorphism and the types of rocks that result from each?

Contact metamorphism occurs locally, next to igneous intrusions and along fractures that were in contact with hydrothermal fluids. Regional metamorphism occurs over very large areas, such as deep within the cores of rising mountain ranges, and generally occurs with the folding of rock layers. Both result in the formation of metamorphic rocks.
