          Abstract

          El estudio de depósitos lacustres datados entre el Pleistoceno Tardío? - Holoceno Temprano vinculado con un modelo de elevación digital han permitido reconstruir la posición de las paleocostas del Sistema lacustre Pueyrredón - Posadas - Salitroso, demostrando la conexión entre ellos, que se verifica en algunos niveles específicos de paleocotas. En este trabajo, se utilizaron como indicadores paleobatimétricos: la ubicación altitudinal relativa de depósitos glacilacustres, depósitos de arenas costeras, depósitos de abanico deltaico en la margen sur del lago Pueyrredón, dataciones absolutas (AMS y 14C), trazas fósiles y comparaciones de malacofauna fósil con la actual para las interpretaciones paleoambientales.

          Translated abstract

          The palaeocoast line positions of the lacustrine system of Pueyrredón - Posadas - Salitroso lakes were determined through the study of the lacustrine deposits, which were dated between the Late Pleistocene? - Early Holocene, together with a digital elevation model (DEM). This has demonstrated the link among them verified on some specific palaeoheight levels. In this research, paleo-bathymetric geoindicators, as relative height of glaci-lacustrine, coastal sand and fandelta deposits onto the southern margin of Pueyrredon Lake, and absolute dating techniques (AMS & 14C), fossil trace and fossil and current malacofauna comparison were used in order to develop palaeoenvironment interpretations.
