Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.
