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

Question

Quizplus · Accepted Answer

The given environmental conditions of 400°C and 5 kilobars are typical of a regional metamorphism, which occurs due to the tectonic forces and high pressures and temperatures deep within the Earth's crust or in collision zones between tectonic plates. Hydrothermal metamorphism occurs due to the interaction of hot fluids with rocks, while contact metamorphism occurs due to the heat from a nearby igneous intrusion. Subduction zone metamorphism occurs due to the subduction of oceanic plates and the resulting high pressures and temperatures.
