Short summary

This paper discusses an integrated approach that provides new ideas about the structure of the eastern Coastal Cordillera in the western Central Andes of northern Chile (27º–28ºS). The integration of gravity and geological information shows that the architecture of this sector is related to the inversion of a Cretaceous rift system. Ages of the synorogenic deposits exposed unconformably over the inversion structure have confirmed a Late Cretaceous age for the Andean deformation in the region.
