Question

What are the different types of metamorphism process?

Answer 1

There are two major kinds of metamorphism: regional and contact. Regional metamorphism. Most metamorphic rocks are the result of regional metamorphism (also called dynamothermal metamorphism). These rocks were typically exposed to tectonic forces and associated high pressures and temperatures.

Answer 2

Process of metamorphism

Explanation:

• The process which operate together in the affected rock to bring about metamorphism are:

1. Granulation
2. Plastic Deformation
3. Recrystallization
4. Metasomatism

• Granulation-The process where crushing of rocks takes place without loss of coherence.

• Plastic Deformation- On the removal of stress if the solid does not regain its original shape , it is said to have plastically deformed.
• Recrystallization-It means either the formation of new minerals or formation of new crystals of the pre-existing minerals.It causes textural and mineralogical changes.
• Metasomatism-It is the process in which the original composition of the rocks are changed primarily by the addition or removal of material.
