The method of spontaneous polarization (SP) is one of the oldest methods used in geophysical exploration. This method facilitates the study of natural electric fields of local nature, electrochemical, filter and diffused origin. The basic premise of successful use of SP is the electron conductivity of mapped and searched objects.


The most common use of SP method:


- Hydrogeology – groundwater flow systems- level of groundwater, flow direction and seepage dams

- Engineering Geology – line constructions, corrosion survey

- Environment – assessment of old environmental burdens – leachates leaks from landfill

- Geology – searching for sulphide ores, graphite, anthracite
