WebContact Metamorphism. Contact metamorphism happens when a body of magma intrudes into the upper part of the crust. Heat is important in contact metamorphism, but pressure is not a key factor, so contact … WebContact metamorphism occurs over a small area of a few feet to several square miles and is usually the result from the heat of intruding magma “cooking” the surrounding relatively cool country rock. Contact metamorphism usually occurs near the Earth’s surface. Metamorphic texture can be foliated ornonfoliated.
WebContact metamorphism—occurs when magma contacts a rock, changing it by extreme heat (Figure 4.14). Regional metamorphism—occurs when great masses of rock change over a wide area due to pressure exerted on rocks at plate boundaries.
