Resumo

The georñorphological and palaeontological studies of the Las Nuevas estuaríne ridge indicates that these silty sands with abundant macrofaune were deposited over clayey marsh deposits during some erosive events at approximately 2000-1800 Cal UC years BP. >4 detailed analysis of the macro- and microfaune included in two drillings collected in this unit permits to delimitate two palaeogeographic sectors during this period: a) to the western, a lagoon with little to very little tidal renewal and; b) the main channel, introducing abundant marine microfaune toward the salt marshes during the tidal fluxes
