The Cafayate depression is a dry valley located in the Pre-Andean region of northwest Argentina. The area shows the development of a large dune field. Its significance has been established from geomorphological and mineralogical evidence, grain shape characteristics and chronological data (OSL dating, archaeological remains, and historical data). The dating results were between 1000-1100 AD to1740-1830 AD showing that the aeolian dynamics remained active during the last millennium. It was not possible to identify stabilised phases marked by ruptures or paleosol development. Nevertheless, other regional and local proxies from Northwest Argentina (archaeological, documentary, etc.) were used to complete the interpretative framework to propose the paleoenvironmental evolution of the area In addition, human activity and land use must be considered as a complementary factor affecting aeolian dynamics during the most recent stage.
