Metamorphic rocks are formed when existing rocks (igneous, sedimentary, or other metamorphic rocks) undergo changes in their mineral composition and texture due to extreme heat, pressure, or chemically active fluids, typically deep within the Earth's crust. These rocks often form at convergent plate boundaries, where tectonic plates collide, leading to the increased pressure and temperature necessary for metamorphism. Additionally, they can also form in other settings, such as along fault lines or in areas of volcanic activity.

Which type of plate boundary is regional metamorphism associated?

Regional metamorphism is associated with convergent plate boundaries where two tectonic plates are colliding. The intense pressure and heat generated during this collision cause the rocks to undergo metamorphism over a wide area, leading to the formation of regional metamorphic rocks.

The type of boundary that the Andes mountains are, in South America, is a convergent plate boundary. This was formed from the collision of the South American plate boundary and the Nazca plate.


What type of rocks formed at divergent plate boundaries?

Mainly metamorphic, due the intense pressure. Some rocks will bend rather than break causing visible folds. Convergent plate boundaries can also produce igneous rocks from volcanic activity due to the subduction of the lighter crustal plate into the mantel which creates a tremendous amount of heat and pressure. Solidified magma may turn into granite. Magma which is blown out from a volcano may take the form of pumice, lava, obsidian, among others.
