This book presents recent findings on the structure and evolution of the Southern Andes. Through a detailed description of a series of orogenic segments reviewed by the different groups that have worked with structural and geophysical tools in each area over the last several years, it illustrates the diversity of mechanisms that have impacted strong orogenic gradients and consequently mountain morphology, from the southern Pampean flat subduction zone to the southern tip of the continent (33-56º S). The book also revises our conventional understanding of the source of the different Mesozoic to Cenozoic sections exhumed in the orogenic wedge, with the objective of discussing basin mechanisms through time. A final chapter discusses probable orogenic controls that have acted together in order to explain structure, the different deformational stages and intra-orogenic extensional collapses that affected the fold and thrust belt over time.
