What Is The Difference Between Regional And Contact Metamorphism

Hornfels is a fine grained rock that shows no signs of layering.

In geology metamorphism is the formation of metamorphic rocks. Contact processes work by raising the local temperature and producing hornfels. There are two major ways of forming a metamorphic rock. Contact metamorphism is metamorphism that happens when preexisting rock comes in contact with a molten rock or magma and it melts locally regional metamorphism is metamorphism happens when two.

Any type of magma body can lead to contact metamorphism from a thin dyke to a large stock. Basically contact metamorphism is when there is contact between magma and any rock bodies. Contact metamorphism is what happens when something really hot like a body of magma molten rock comes in contact with colder rock. Contact metamorphism is the name given to the changes that take place when magma is injected in the surrounding solid rock country rock.

Regional metamorphism works by compressing rock which can often cause the rock to be layered or foliated. The main difference between contact and regional metamorphism is that contact metamorphism occurs in a small region whereas regional metamorphism occurs in a wide area. There are a couple of ways this can happen. Contact metamorphism and regional metamorphism.

Himalayan range is a good example of the results of a regional metamorphism. Contact metamorphism is a metamorphism process that is completely different from the regional metamorphism above. The type and intensity of the metamorphism and width of the metamorphic aureole will depend on a number of factors including the type of country rock the. Metamorphism is the changing of minerals and textures in a rock as a result of exposure to heat and or pressure.

Each type of metamorphism generates distinct rock types. Difference between regional and contact metamorphism.
