The Principal Cordillera of the semiarid Andes is a transient relief that developed after the Andean uplift initiated in the Oligocene. Pediment altitudes of the Principal Cordillera in relation with others of the Coastal Cordillera indicate two kilometers of uplift. In response to the uplift depth-incised valleys (~2 km) were excavated in the high cordillera during the last six million years. The incised volume of the valleys and 10Be concentration of fluvial-glacial sediments indicate erosion rates from thirty to seventy-five meters per million years, values that have been relatively constant during the last six million years. During this period the dynamic of material transfer has been modulated by glacial erosion and exportation of fluv...
