Since the late Oligocene ongoing shortening produced fold and thrust belts in the backarc region of the Central Andes, which led to the development of foreland basins. The formation of foreland basins is related to regional isostatic compensation of fold–thrust belt loading. We carried out a flexural modelling along an E-W profile (21.4°S) in order to reproduce the Subandean basins evolution and the Cordillera Oriental and Sierras Subandinas uplift history through time. We used the software tAo.
