Geoelectricity refers to the study and application of electrical phenomena occurring in the Earth's crust. It involves measuring the Earth's natural electric fields and the electrical properties of geological materials. This field is important for understanding subsurface structures, mineral deposits, and groundwater resources. The techniques used in geoelectric studies include resistivity surveys and induced polarization, which help identify variations in the Earth's electrical conductivity. These methods are valuable in environmental assessments, resource exploration, and geotechnical engineering, providing insights into the Earth's composition and behavior.
