The geophysical result from the survey is visualized in the section below. The vertical bars indicate the TEM soundings along the section line.
Low resistivity layers (resistivity < 40-50 ohmm) reflect clay- or silt-rich layers. In this interval, decreasing resistivity reflects increasing content of clay/silt. High resistivity layers represent layers of sand, gravel, sandstone or limestone. The layer of very high resistivity seen from approx. 800 meters until 500 meters above sea level is interpreted as layers of sandstone or limestone above the groundwater table.
The drop in resistivity from >300 ohmm to 100 ohmm at approximately 500 meters above sea level is interpreted as the regional groundwatertable located within a layer of sandstone or limestone.
Based on the geophysical results, a preliminary interpretation of the limestone bedrock interface is produced:
