Thermal (contact) metamorphism typically occurs when rocks are in contact with hot magma or lava. The heat from the magma or lava causes the rocks to recrystallize and metamorphose, but without the intense pressure required for foliation. Therefore, nonfoliated rocks such as marble, quartzite, and hornfels are typically produced by thermal metamorphism.
