Investigation of Structure of Various Surface Karst Formations in Limestone and Dolomite Bedrock with Application of the Electrical Resistivity Imaging

Abstract

Karst landforms are developed in different kind of rocks and in different structural settings. Authors are presenting some results of profile measurement of Electrical resistivity imaging in some dolines and collapse dolines that developed in lime­stone and dolomite in Slovenia. Selected features are examples of surface karst landforms whichcould be morphologically de­fined as typical of its kind. For electrical resistivity imaging data collection was used SuperSting R1/IP earthresistivity meter. Electrical resistivity imaging method was applied for researchof material characteristics beneathsurface of karst landforms. Materials withhigher portion of water as fractured bedrock or clay are less resistant to electrical current than unfractured bed­rock. Application of the ERI method has turned out as appro­priate for detailed investigation of surface karst landforms.
