Regiony hydrogeotermalne na Niżu Polskim

The paper provides a proprsal to divide the three main Mesozoic hydrogeothermal reservoirs of the Polish Lowlands into regions. The division is based primarily on reservoir efficacy in terms of using thermal waters for heating and recreation purposes. The presented validation of individual regions and sub-regions shows that only some parts of them have a medium or high heating potential. The heating and recreation potentials are limited in many places by the high mineralization of thermal waters.
