Abstract

The main goal of near-surface geophysical studying is development of precise and reliable physicalgeological model of the underground. Karst terranes usually differ from the host media by their physical characteristics (density, magnetization, electric and thermal conductivity, electromagnetic and seismoelectric properties, polarizability, etc.) that allowing to applying a set of corresponding geophysical methods for displaying of karst phenomenon. Potential (gravity, magnetic, thermal, selfpotential and direct current) and quasi-potential (induced polarization and VLF) geophysical fields are inexpensive, prompt and effective tool for recognizing and localization of karst terranes. The developed interpreting system (described mainly in Khesin et al. (1996)) includes special methods for advanced analysis of anomalies of the aforementioned fields observed under complicated environments: inclined relief, oblique magnetization (polarization) and unknown level of the normal field. Another component of the system is a 3-D combined modeling of gravity and magnetic fields. The developed system has been successfully applied on models of karst terranes and in real situations.
