DÉFORMATIONS NÈOGÈNES LE LONG DE LA CÔTE NORD DU CHILI, AVANT-ARC DES ANDES CENTRALES

Abstract : In northern Chile the Mejillones Peninsula (23ºS) and the Caldera (27°S) areas were studied to understand the relations between brittle deformation and coastal uplift. The stratigraphic and morphostratigraphic analyses make it possible to calculate the coastal uplift rates. The dating of alluvial fan surfaces by in-situ 10Be method is used to characterize the paleoclimate and calculate fault slip rates during Upper Pleistocene. The fault analysis allows to calculate the directions of extension and compression. In conclusion we discuss neotectonic chronology and subduction seismic behaviours
