At the continental scale, the Andes presents significant curvatures. One of the largest is the curvature of Patagonia, where the orogen and its main tectonic provinces are rotated about 90 ° from an NS direction at 50 ° to an EO orientation in Tierra del Fuego. Despite its importance, the origin of...
