- Abstract
The development of Toplita geothermal spa for tourism requires new geothermal resources, geophysical and hydrogeological works being carried out during the last decades. A geophysical study based on the new ERT (Electric Resistivity Tomography) technique was recently performed, the resistivity tomography data being integrated with gravity, magnetics and previous VES (Vertical Electric Sounding) measurements (Ursu, 1994). Experiments related to applying the ERT technique in the Bradul spa area (Toplita) showed that the Schlumberger array provides better results for deeper levels as compared to the Wenner one. To better illustrate the spatial distribution of apparent resistivity within the subsurface structures the VES sections were calculated for AB/2 and AB/3. The integrated interpretation of ERT and VES resistivity data lead to the drilling of a new hydrogeological borehole in the Bradul spa area. A highly tectonized zone containing thermo-mineral water was twice crossed at 190m and 200m depth, its temperature being similar to that exploited in the Bradul spa (27 0C). When estimating the depth of apparent resistivity anomalies in the Bradul spa area a better fit was offered by the VES section calculated for AB/2.5
