Formation of Metamorphic Rocks

3.4 Metamorphic Rocks

◆ Regional metamorphism results in
large-scale deformation and high-grade
metamorphism.

Directed pressures and high temperatures
occur during mountain building.

Produces the greatest volume of metamorphic
rock

Regional metamorphism, which occurs during mountain building, results in large-scale deformation and high-grade metamorphism due to directed pressures and high temperatures. This type of metamorphism produces the greatest volume of metamorphic rock.

Regional metamorphism, which occurs during mountain building, leads to extensive deformation and high-grade metamorphism. This process involves the application of directed pressures and high temperatures, resulting in the formation of a significant amount of metamorphic rock.

The formation of metamorphic rocks, specifically through regional metamorphism, occurs when there is large-scale deformation and high-grade metamorphism, often caused by directed pressures and high temperatures during processes like mountain building. This type of metamorphism is responsible for producing the largest volume of metamorphic rock.
