Chemical and isotopic characterization of the thermal fluids emerging along the North-Northeastern Greece.

ABSTRACT: Hydrochemical and isotopic characteristics of fluids from major geothermal fields of middle/low temperature in N/NE Greece are examined [basins: Strymon River (SR), Nestos River Delta (ND), Xanthi-Komotini (XK), Loutros-Feres-Soufli (LFS) and Rhodope Massif]. The geodynamic context is reflected to isotopic/chemical composition of fluids, heat flow values and elevated CO₂ concentrations in emitted fluids. B and Li are derived from leaching of the geothermal systems hosting rocks. δ¹⁸O_H2O, δ¹⁸O_SO4, δ¹³C_CO2 values and chemical compositions of Cl, B and Li of geothermal discharges suggest two distinct source fluids. Fluids in SR exhibit high B/Cl and Li/Cl ratios, suggesting these constituents are derived from associa
