ABSTRACT
Geothermic conditions of geothermal aquifers can either be characterized by temperature of geothermal water measured in existing deep wells or estimated using geothermometers based on the chemical composition of geothermal water. Geothermometers were applied on five geothermal boreholes PP-1 Poprad, VSC-1 Velky Slavkov, FGP-1 Stara Lesna, Vr-1 Vrbov and Vr-2 Vrbov in the Poprad Basin, north-eastern Slovakia. The temperature on the Pre-Palaeogene basement, composed mostly of Mesozoic carbonates, varies from 40 °C to 117 °C in this area, the highest temperatures are at the depth of 3 200 – 3 300 m. Temperature values estimated by geothermometers were compared with real geothermal water temperatures. The K/Mg, chalcedony, and α-cristobalite geothermometers were chosen as the most suitable onesfor the Poprad Basin conditions.
