Summary:Seven thermal springs (T 26°-40°C; TDS 0.8-6.8 g/litre) from the province of Catanzaro, Italy, were studied. Three hydrogeochemical types were recognized: sodium chloride, sodium sulphate and alkaline earth sulphate waters. Taking into account the geological setting and minor element behaviour (SiO2, H3BO3, F, Li, Sr, Br), the following hypotheses were formulated: 1) the salt content in sodium chloride and sodium sulphate waters (Ponte Coniglio, Bruciarello and Repole) is derived from dissolution of Messinian evaporitic deposits, which probably still contain residual brines of marine origin; variations in the chemistry of waters may be explained by lateral variations in the lithology of those terrains; 2) the alkaline earth sulphate waters (Caronte and S.Elia) derived their salt content by interaction with evaporitic deposits (mostly gypsum) associated with Triassic dolostones. Silica geothermometry (chalcedony) suggests T 24°-64°C. The dilution relationships among some springs are also mentioned. (Authors' abstract) [J.M.H.]
