Ionic ratios (Br[sup [minus]]/Cl[sup [minus]], Na[sup +]/Cl[sup [minus]], SO[sup 2[minus]][sub 4]/Cl[sup [minus]]) of the samples taken from thermal springs sited at Argenos-Eftalou, Polichnitos-Lisvori, and near Mytilini, on Lesbos Island, are typical of marine solutions. Stable isotope contents of these waters show that they may result from mixing between meteoric and sea water. Virtually no Cl[sup [minus]] is supplied by rock leaching. Balance equations based on oxygen-18, deuterium, and Cl[sup [minus]] contents indicate that marine sources contribute approximately one-third of the water at Argenos, Polichnitos, and Lisvori, and 100% for one of the springs, Thermi, in the Mytilini area. Sulphur-34 contents of dissolved sulfates confirm the participation of marine solutions. Equilibration temperatures based on oxygen-18 contents of dissolved sulfate and water are similar to those given by the chemical geothermometers, except for Thermi spring. The validity of the [Delta][sup 18]O (SO[sup 2[minus]][sub 4] [minus]H[sub 2]O) temperature for the latter is thus questionable.
