Resumen:
The Cordillera del Viento (CV) is the western sector of the inner Chos Malal fold and thrust belts (CMFTB) and exposes basement (Carboniferous and Permo-Triassic) and its cover rocks of the Neuquén basin (Late Triassic to the Neogene). Sánchez et al. (2020), based on thermochronology data performed in the diff erent units of the Neuquén Basin, defi ne that the faults of the CMFTB, shows a normal sequence of deformation toward the foreland from Late Cretaceous to Late Miocene. In this contribution we present the fi rst zircon fi ssion tracks (ZFT) and apatite fi ssion tracks (AFT) analyses carried out in the basement rocks of the Neuquén basin in order to give a contribute to the understanding of the evolution of the innerthick-skinned zone of the CMFTB.
