convergent
The most common type of land metamorphism is Regional metamorphism. The most common rocks are slates, schists, and gneisses. This occurs within the folds of mountain belts and cratonic areas.
Contact metamorphism does not often produce the foliation caused by regional metamorphism
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
Contact Metamorphism
The type of plate boundary that regional metamorphism is associated with convergent plate boundaries. A convergent boundary is also known as a destructive plate boundary due to subduction.

Regional Metamorphism
Regional metamorphism
Contact - Close to a hot spot Dynamic - Along a transform boundary Impact - Near a crater Regional - At deep subduction areas
Regional metamorphism can occur.

Regional. Contact metamorphism is high temperature-low pressure so no mineral alignment occurs, only new mineral growth.
