Resumen:
In the Central Andes, supracrustal tectonic loading has been extensively invoked to explain retroarc flexure and foreland basin subsidence. However, we present surface and subsurface stratigraphic data from the Sierras Pampeanas broken foreland, Argentina, that suggest a long-wavelength subsidence pattern, likely driven by processes occurring in the upper mantle or lower crust. Short-wavelength deformation would have superimposed to the regional subsidence features.
