Abstract

Scientific bibliography is rich of papers pertinent to the hydrogeological features of Salentine Peninsula. But some exceptions, the previous hydrogeological studies have mainly concerned sweet waters and their relationship with seawater of continental intrusion. Never really faced, a characterization of seawater should be very interesting on account of sea-level variations which have affected the Salentine Peninsula during last 20000 years. Beginning from a local and detailed stratigraphic reconstructions of Lower Salento, in the belt included between S.Pietro in Lama and S. Foca, on the basis of structural features and stratigraphic correlations, an area is been recognized which should have likely preserved proofs of local hydrogeological evolutions. On the basis of thermo-salinity logs and chemical analysis of deep seawater samples, the following investigation have highlighted the presence of two anomalous areas in comparison with current hydrogeological condition. In fact under post-cretaceous coverage of Lizzanello area, there are not seawaters, according to hydrostatic equilibrium, but there are brackish waters in a transition zone that is larger than 60 meters. This situation can be interpreted only with presence of sweet waters that have been trapped inside structural elements faulted at different highs by tectonics, as consequence of sea level going up. On the other hand in the neighbouring area of Vernole, the more depth of calcareous bedrock causes the exclusive finding of seawaters under post-cretaceous coverage: the age of this waters can be supposed as the same of flandrian transgression beginning
