- •
The Andean thrust systems in the Chilean Frontal Cordillera correspond to doubly-vergent thick-skinned thrust faults.
- •
Shortening of previous rift systems and basement highs constitute the main tectonic processes during the Andean deformation.
- •
The Andean deformation in the region started as early as Late Cretaceous.
- •
Propagation of large basement east-vergent mega-ramps have provided a minimum of 18 km ok shortening in the region.
