If pressure is exerted from all directions, then the rock usually does not show foliation. There are two main types of metamorphism: Contact metamorphism—occurs when magma contacts a rock, changing it by extreme heat (Figure 4.14).

WebThe rock produced is often a fine-grained rock that shows no foliation, called a hornfels. Regional Metamorphism ... Cataclastic metamorphism occurs as a result of mechanical deformation, like when two bodies of rock slide past one another along a fault zone.
