Carbogaseous mineral water in Bosnia and Herzegovina and Serbia as indicator of deep hydrogeothermal resources

Abstract

Continuous and abundant CO2 seepage at the sources and springs of geothermal water, the geological composition, hydrogeological and geothermal properties of earth's crust in the upper sections, where this phenomenon takes place indicate that CO2 has been generated continuously during geological processes. In our opinion this is due to thermolysis, that is the process of carbonate rock decomposition by heat in geothermal aquifers and in the presence of geothermal water. Therefore, abundant seepage of CO2 may be a clear indicator of deep hidden reservoirs of geothermal waters, which are composed of carbonate rocks (limestone, marble, dolomite, calcschist), or to be more specific the indicator of hidden hydrogeothermal resources in deep geothermal reservoirs.
