Abstract
The chemical and isotopic features of salt ground waters in the Salento coastal karstic aquifer (Apulia, Southern Italy) reveal that they are very different from modern seawater. Chemical data allow identifying the role of water-rock interaction (Ca2+-Mg2+ exchange due to dolomitization, Na+-Ca2+ or Mg2+ base-exchange, SO4 2- reduction, solution of evaporite salts) in the modification of the chemical characteristics of original seawater. 87Sr/86Sr isotope ratios and Sr indicate that salt waters are very ancient and, given the structural features of this aquifer and the paleogeography of the region, they probably date back to the Flandrian transgression. New findings in a thermal area overlooking the Adriatic Sea suggest new scenarios for the role of Ca-Cl2 brines, until now unknown.
