Integrated Geophysical and Geological Investiga-tions of Karst Structures in Komberek, Slovakia

Integrated geophysical and geological investigations in Komberek, Slovakia, have revealed subsurface cavities at depths of approximately 50 to 60 meters below the surface. The study utilized a combination of dipole electromagnetic profiling, radiometric mapping, high-definition magnetometry, microgravity, and electrical-resistivity tomography (ERT) to create a detailed near-surface geological model. These methods distinguished between natural sinkholes and man-made lime-kilns, while ERT and gravity modeling identified cavities characterized by contrasting geophysical properties—ranging from highly resistive air-filled voids to low-resistivity loamy water-filled fractures. The research demonstrates the effectiveness of multi-method geophysical approaches in accurately mapping karst structures, providing critical insights for geological studies in protected areas like UNESCO World Heritage Sites.
