what area of the united states has experienced regional metamorphism
Answers
Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks.
ANSWER:
The central Virginia to Alabama are the area of the United States has experienced regional metamorphism.
EXPLANATION:
The regional metamorphism occurs when rooks are found to be deep inside the crust, undergoing deformation. This occurs over huge area. This occurs due to deformation at the orogenic event resulting in mountain belt have been eroded. The burial range of 10 km to 20 km is required. The areas affected is found to be large. This mostly occurs with in continental crust.
