| Abstract: | The Hungarian Basin is a large depression. The deep multilayer flow-system of this basin represents a thermal circulation in equilibrium under natural conditions.The terrestrial heat-flow of the basin can be considered balanced, therefore, any geothermal anomaly is of convective origin. Negative geothermal anomaly and low salinity of the water characterize the recharge area and positive anomaly and high salinity the discharge belt. All is proved by geothermal, hydrochemical and hydrodynamic maps of the thermal water aquifer. Deep flow through thick and highly permeable deposits of the main recharge area cause strong negative anomaly and very low salinity. Extreme anomalies are of tectonic origin. |
