Abstract

We present here results of our investigation of the isotopic chemicalcomposition of groundwater and carbonates in the Surdulica geothermalaquifer, Serbia. We considered the effects of carbonate dissolution and measured C-13, C-14, D, O-18, H-3, field pH, temperature, Na+, Ca2+, Mg2+, HCO-, and other aqueous species from 30 springs and boreholes. Geothermal waters are supersaturated with calcite. Carbon isotope compositions vary with carbonate mineral dissolution. The deltaD and deltaO-18 of groundwater samples fit the meteoric water line, and indicatethat groundwater is recharged mainly from higher altitudes and the cold season. Different groundwater residence times point out two mechanisms for their formation: fissure flow for young waters and standard diffusion processes for old ones.
