The Andean orogeny commenced in the Cretaceous, but was preceded by backarc extension starting in the Jurassic. Here, the author presents a 4D geodynamic subduction model reproducing the evolution of overriding plate deformation along with a progressive decrease in slab dip, explaining Jurassic-present arc migration.
