A low enthalpy geothermal system in the Moesian platform

In the central part of Moesian Platform in Romania, there is a Mesozoic carbonate aquifer whose water temperatures are from 42°c to 80°C. The goal of this paper is to describe the geothermal system - origin of the water, peculiarity of the hydrothermalism - and the stage of practical utilization. The approach to these problems was by of geochemical methods: hydrochemical analyses, specific conductivity and temperature measurements, environmental isotopic analyses (D, 18O, 3H, 14C). The main conclusions: - the origin of the thermal waters almost exclusively meteoric; - the reservoir has no high enthalpy potential
