“…The result is that although the different levels of limestone are separated by impermeable sediments, in fact the limestone bodies are connected to each other and form a unitary system from a hydrogeological point of view. Based on hydrogen isotopes (Papp and Cociuba, 2011), it has been established that most of the sources of groundwater in the area (springs and geothermal waters) are of meteoric origin, but a source of fossil water of marine origin could be highlighted. Also, it has been established that the residence time of the geothermal waters is relatively low and that their mineralization occurs mainly in the karst area in the cold-water stage.…”

The iterative 3D geological modeling/inversion program (GeoModeller Base -Geology Modelling and GeoModeller Full Gravity / Magnetics) from Interpid Geophysics (Australia) has been implemented (installed and tested), based on a partial academic license (modules: Geology, Magnetism , Gravimetry) valid until 31.01.2023. Geological, geophysical and geochemistry data modelling represents the construction of the geological model, based on all input data (processed geophysical data, with iterative algorithms for direct and indirect geophysical problems, digitalized geological data, geochemistry data), editing, visualization and advanced management. The direct problem (named modeling) and the indirect problem (named inversion) are solved iteratively based on the optimization of the properties of the combination of: gravity, magnetism and 3D geological constraints. An input database was created for the modelling program that include all knowledge data. These data have been supplemented from several sources, starting with the data from bibliography, published works and reports, digitization and quantification of information and detailing some of them by geological prospecting, mapping and geophysical field measurements. In paper is presented the geological framework of the study area from Pannonian Depression, an area with a strong geothermal potential. Also, an extended map for the North-West of Romania of the Bouguer anomaly, the Free Air anomaly, the temperature at 3000 m depth and the geothermal flow is presented. These data are supplemented by bibliographic sources with the description of water chemistry.

“…Such mixing phenomena can be appropriately studied using the correlations between deuterium concentration and total salt content of the water (e.g. Gat, 1971;Payne, 1981;Papp and Cociuba, 2011;Papp et al, 2017). For underground water, and for geothermal water in particular, water/rock interaction processes could affect their isotopic composition.…”

The research activities consisted in the inventory of stable hydrogen isotopic and geochemical data for mineral and geothermal waters belonging to the Olănești resort in order to define their origin, genetic relationships and underground dynamics in the geological context of the Getic Depression. Comparative study with other Carpathian zones (i. e. East Carpathians, Apuseni Mountains, Pannonian Basin, Transylvanian Basin, Getic Depression, and External Flysch) has also been performed. Previous hydrogeological, hydrochemical and isotopic studies identified three components for the groundwaters in the Olănești area: deep formation waters, local infiltration waters (especially from the Olăneşti Valley), and waters from high altitudes. Formation waters from Olănești and from other resorts in the Getic Depression (Călimenești – Căciulata and Govora) display mean δD and TDS values similar to those of formation waters in the Balvanyos - Covasna area (East Carpathians), and also to the salt waters in the Transylvanian Basin. The major contribution of formation water to the genesis of mineral waters in the Getic Depression makes them extremely vulnerable to degradation over time because formation water is a „fossil” not renewable component.
