The Dynamics of Continental Accretion

USC scientist Meghan Miller is among an international team of researchers who used computer modeling to reveal, for the first time, how giant swirls form during the collision of tectonic plates, with subduction zones stuttering and recovering after continental fragments slam into them.

The team’s 3-D models suggested a likely answer to a question that has long plagued geologists: Why do long, curving mountain chains form where two tectonic plates collide, pushing one down into the mantle?
