Abstract

The north-south structural evolution in the Subandean zone (eastern side of the Central Andes) reflects the complexity of the orogenic front that propagates on an heterogeneous substratum inherited from pre-Andean palaeogeographies. The construction of balanced cross-sections shows that this north-south evolution corresponds to a progressive transformation from thick-skin transpressive deformation to thin-skin compressive deformation. The thrust front propagation is controlled, in the north, by NNE-SSW to north-south rift systems Permo-Triassic to Jurassic in age, oblique to the chain, and in the south, by the relatively isopach series of the preserved Palaeozoic silico-clastic platform.
