Geoelectric Investigation of a Multidirectional Fissure System in a Karstic Area

P047 GEOELECTRIC INVESTIGATION OF A MULTIDIRECTIONAL FISSURE SYSTEM IN A KARSTIC AREA SZALAI S. Abstract 1 Numerous publications are known about a direct geophysical investigation of unidirectional fissure systems but there have been no reports about the problem of multidirectional fissure systems. The few surface geophysical methods which could be potentially used for this purpose have numerous probably unresolvable difficulties. In this paper we present an attempt to map the multidirectional fissure system in a buried limestone surface by combining geoelectrical profiling and geoelectrical azimuthal measurements. Results received by using both the so-called null- and traditional arrays were interpreted together.
