Metamorphic rocks that developed by recrystallization on a regional scale over large areas, hundreds of km2 in extent, are the products of regional

Regional Metamorphism is a kind of metamorphism that depicts the texture of rocks due to deep burial and heating. It is associated with the large-scale forces of plate tectonics. Generally, it occurs in large areas that do not have any relationship with igneous bodies. Regional Metamorphism Regional Metamorphism. When rocks are buried deep in the crust, regional metamorphism occurs. This is commonly associated with the boundaries of convergent plate and mountain range formation.

regional metamorphism [ rē ′jə-nəl ] A type of metamorphism in which the mineralogy and texture of rocks are changed over a wide area by deep burial and heating associated with the large-scale forces of … 2015-09-01 2019-09-23 Regional metamorphism is metamorphism that occurs over broad areas of the crust. 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 Regional metamorphism includes any metamorphic process that occurs over a large region. It is therefore the most widespread and common type of metamorphism. A rock is squeezed under directed pressure during metamorphism it is likely to be deformed, and this can result in a textural change such that the minerals are elongated in the direction perpendicular to the main stress.

As described above, regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges. Because burial to 10 to 20 kilometres is required, the areas affected tend to be large—thousands of square kilometres.

• Contact metamorphism (heat) . • Dynamic metamorphism (pressure).

Regional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced.
