INVESTIGATION OF STRUCTURE OF VARIOUS SURFACE
KARST FORMATIONS IN LIMESTONE AND DOLOMITE
BEDROCK WITH APPLICATION OF THE ELECTRICAL
Uroš Stepišnik, Andrej Mihevc - (37/1,2008)
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 which could be morphologically defined
as typical of its kind. For electrical resistivity imaging data
collection was used SuperSting R1/IP earth resistivity meter.
Electrical resistivity imaging method was applied for research
of material characteristics beneath surface of karst landforms.
Materials with higher 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.
