Electrometery is a geophysical method successfully used by decades. By Electrometry we measure the resistance of underground materials to the passage of electric current.
Resistivity involves injecting current through two or more electrodes and measuring the response of the underground materials using other two or more electrodes; voltage decrease is due to the water content and to the electrical conductivity of various rocks. All data recorded in the field are sent to a laptop for viewing and interpretation using DataViewer software.
Applications of electrometry :
- Local and regional geology issues (bedrock identification)
- Areas with landslides,
- Determination of groundwater depth,
- Correlation of geologic layers,
- Issues of economic geology (determination of salt structures and of the areas with useful rocks, etc.),
- Issues of hydrogeology (determination of the layers of freshwater and mineral water),
- Issues of technical geology (determining the nature of the rocks, their depth and topography, the geotechnical features of the soil).
