The Euganean thermal waters (65-86°C) constituting the homonymous thermal field (Euganean Geothermal Field ; Veneto region ; NE Italy) are investigated in this work to constraint the time scales of their upwelling based on Ra and Rn isotopes. Two groups of samples can be distinguished on the base of the 223Ra/226Ra and goethite saturation index. The thermal waters in the northern part of the thermal field are characterized are characterized by goethite S.I. 1.6) and in general characterized by 223Ra/226Ragreater than equilibrium value (0.046). This result was interpreted as connected to a slower rising path through a finely fractured aquifer yielding an enhanced water/rock interactions. |
