“…The voltage does not return to zero instantaneously and decays slowly, indicating that charge has been stored in the rocks. In simple terms, the IP effect reflects the degree to which the rock/soil can store electric charge when an electric current passes through it in a manner analogous to a leak capacitor (Dobrin Lise 1998; Kiberu, 2002;Martinez-Moreno et al 2013;Chabaane et al 2017a;Besser et al 2017;Tkachev et al 2017).…”

The Maâmoura aquifer is located on the eastern coast of the Cap Bon peninsula. During recent decades, the agricultural exploitation of water has been strongly reinforced, causing an over-pumping of the groundwater resources accompanied by an intrusion of seawater. The geophysical approach based on electrical resistivity tomography has been adopted to obtain high-resolution electrical sections imaging, which allows delineatation of the areas characterized by a high salinization and reconstructs the geometry of the saline wedge front. In fact, the presence of seawater in the aquifers reduces subsurface resistivity values. In this study, five electrical profiles were performed using the Terrameter SAS4000 Lund Imaging System with an array of 64 electrodes. The Wenner configuration was used with a unit electrodes spacing of 5 m. Finally, we use hydrogeological data, and electrical resistivity tomography data superimposed with the location of wells to provide a conceptual framework for the understanding of the freshwater-saltwater interface in the Maâmoura region.

“…The rough strike and depth of the mineralization belt were delineated and the anomaly section with low resistivity and high chargeability was considered a prospective area. Tkachev A. V. [8] conducted IP soundings to identify the metasomatic belt of carbon in a gold deposit. Only an metallogenic environment was detected in relation to gold without identifying the mineralization concentration.…”

Prior research has confirmed that the Fufang prospecting area exhibits good mineral anomalies. The geochemical anomaly that pertained to copper content was delineated within a wide range; hence, the deployment of boreholes and trenches was hindered for further prospecting work. To shrink this anomaly range and identify favourable areas for mineralization, a combination of geophysical methods based on electrical and magnetic theories was proposed. First, magnetic and induced polarization (IP) mappings were utilized to characterize the distribution of anomalies horizontally. Then, the major structures were identified using IP and audio magnetotelluric sounding measurements. The integrated geophysical anomalies with good spatial consistency were also delineated. Results demonstrate that the main strike of the regional fault is in the direction of NE 50°, and some parallel secondary faults are also inferred. The dykes in this area are well developed in the strata due to rock mass intrusion. Several geophysical anomalies are highly superposed. This condition indicates good prospecting of copper and polymetals. The found anomalies delineate a new prospecting area that is 62% smaller than the previous one. This study provides a good prospect in the designated anomaly area.
