Territory of the City of Bijeljina has not been subject of dedicated geothermal research. Therefore, the data on the thermal characteristics of this area were obtained according to analysis and reinterpretation of results of other types of relevant geological research, as well as according to the analysis of the composition, thickness and development of the Earth’s crust of this and neighbouring parts of Ex-Yugoslavia.
 

Basic indicators of geothermal characteristics of any terrain depend on the following factors: thickness and composition of the Earth’s crust, lithosphere thickness, age of tectonic activity, age and type of magmatic processes, content of radiochemical elements in rocks, neo-tectonic movements, seismicity, hydro geological characteristics of the terrain, etc. All these factors are present in the territory of Semberija, so they have more or less impact on individual geothermal characteristics, or parameters.
 
Heat flow value in Semberija is 90-110 W/m². These values are 50-80% higher than the average value of terrestrial heat flow density for the continental part of Europe, which is around 60 W/m².
