“…These methods allow for studying the underlying rock mass in which mineralised structures may exist [4,[11][12][13] and to delineate the geometry of the sedimentary basins [14][15][16][17][18][19][20]. Thus, the IP method is complementary to the ERT and has been proven to be very useful in searching gold deposits, massive ore sulphides, graphite or bentonite deposits, as well as in investigating the contamination of aquifers by organic or inorganic substances [4,5,11,21,22]. The combination of these techniques has also been used in the detection of deeply buried caves [23], seepage [24] and slope stability [25].…”

The aim of this study is to prove the effectiveness of two electrical geophysical prospecting techniques, namely electrical resistivity tomography (ERT) and induced polarization (IP), in locating thin vein structures of metal sulphides embedded in Palaeozoic materials underlying a sedimentary cover. For this purpose, a Quaternary basin known as La Garza was selected, located in the mining district of Linares-La Carolina (Southern Spain). Galena (PbS) veins appear abundantly throughout this area, hosted in the Palaeozoic granitic bedrock. The studied veins show thicknesses from 0.5 to 2.0 m, and most present a vertical planar distribution. The veins lose their continuity below the sedimentary cover due to normal fractures that control the subsidence of the basin. During the 1980s, geophysical research campaigns were carried out in La Garza using vertical electrical sounding and failed in detecting the hidden veins. For this reason, to carry out this study, a closed regular mesh was designed, composed by eight ERT and IP profiles, with variable lengths between 315 and 411 metres. An electrode spacing between 5 and 7 metres was selected, thus allowing the granite bedrock to be reached without significantly reducing the resolution capabilities of the method. Even though ERT and IP are well-known geophysical techniques for mapping ore deposits, this is a case study that shows the advantages of the simultaneous use of both techniques (ERT and IP), over their individual application. ERT allows for reconstructing the morphology of the basin and the fractures that control it due to high-resistivity contrast between the overlying sedimentary cover and the underlaying granitic basement. However, it cannot provide any insights about their degree of mineralization. At this point, it is the IP technique that makes it possible to differentiate which are the mineralized structures. Some of these fractures produce high (above 50 mV/V) and moderate (below 50 mV/V) chargeability values, suggesting the existence of several unexploited metal veins. Furthermore, the derived models enable researchers to analyse the morphology of this sedimentary basin controlled by normal faults.

“…The survey was carried out using ABEM Terrameter SAS4000 together with ABEM LUND ES 10 - 64C, the electronic switching selector unit, Fig. 3 , [ 2 , 5 , 6 ]. Six (6) ERT geophysical survey lines were conducted at the project site, using the Wenner-Schlumberger array to obtain the expected minimum depth of the subsurface stratum at about 35 m. The survey data helped to delineate depth of the industrial, and municipal waste materials, and hence, the contaminants volume of the prism shape generated was approximated [1] .…”

“…IP, AMT, and magnetic explorations are effective in detecting polymetal concentrations, concealed faults, and lithology. Arifin [7] applied the IP method to acquire a 3D model of resistivity and chargeability in a gold mineralization area. 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.…”

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.
