Sedimentary rock can be metamorphosed by: a) exposure to heat by close proximity to a heat source such as a plutonic intrusion; b) from deep burial pressures; c) from directed pressure and heat from mountain building processes; d) chemical changes from exposure to heated fluids, the fluids heated by a plutonic intrusion. Metamorphism of sedimentary rocks can result in a realignment of mineral constituents, recrystallization, or new chemical compositions.
