Question

What kind of metamorphism will occur if the environmental conditions are 400°c and 5 kilobars?

Answer 1

Answer;

Regional metamorphism

Explanation;

• Regional metamorphism takes place when rocks are buried deep in the crust. It is commonly associated with convergent plate boundaries and mountain range formation.
• In other words regional metamorphism takes place over wide areas and results from both pressure and temperature generated at convergent plate margins during subduction and continental collision.
• It results in deformation in non-hydrostatic and differential stress conditions and creates strongly foliated metamorphic rock (slates, schists, gneiss)
