Investigation in Sinkhole Terrains Using Complex of Geophysical Methods – Case Study in the Karst Area, Slovakia

Researchers identified two significant underground structures with low density and resistivity in the Aggtelek Karst and Slovak Karst region, suggesting potential karst formations. The study employed a multidisciplinary geophysical approach, combining electromagnetic conductivity mapping (CMD), gamma-ray spectrometry, high-definition magnetometry, microgravity, and electrical resistivity tomography (ERT). These methods were used to distinguish between natural sinkholes and historical lime-kilns, while also investigating the spatial distribution of carbonate rocks and sediments. The findings highlight the effectiveness of integrating multiple geophysical techniques for detailed geological mapping and cave exploration in karst terrains.
