In the Western Cordillera of northern Chile, the Proterozoic-Paleozoic Belén Metamorphic Complex is covered by late Oligocene-early Miocene (25-18 Ma) rocks, and both units are involved in west-vergent contractional deformation, which results in exhumati...

We investigate the mass balance of the Cenozoic Andes-Amazon source to sink system using rock uplift proxies and solid sedimentation of the Marañón Basin in Peru. The evolution of sedimentation rates is calibrated with regional structural r...

Crustal thickening by horizontal shortening and associated deformation have been broadly considered as
prime mechanisms for mountain building in the Central Andes of western South America. However, timing and structural
style of Andean orogeny in norther...

The Cordillera de los Andes is the typical example of a subduction-related orogen. Its present topography is the result of post-Miocene uplift, however, Andean compressional deformation and uplift started in the Late Cretaceous, as increasingly recognize...

The eastern Andean orogenic front at 36ºS shows unique attributes when compared to neighbor segments, from an anomalous eastward development of the orogenic front area due to the uplift of a zone of reduced topography in the foothills constituting a pre-...

The Andean Paleozoic basement of the Cordón del Plata (Argentina) consists of two sets of rocks showingdifferent stratigraphy, structure and metamorphism. The lower one is represented by the pre-Carboniferous (Devonian?)Vallecitos beds. These rocks have ...

In the Argentinean side of the Andes at 34°40?S, the Cenozoic Andean orogeny produced the thick-skinnedMalargüe fold-and-thrust belt and the easternmost basement uplift of the Cordillera Frontal. Integrating balanced structuralcross-sections with previou...
