“…A 2D multielectrode ERI survey is conducted using 61 units of stainless-steel electrode connected to a multicore cable. The electrodes attached to the cable take-outs are then placed along a survey line into the ground at a specified daily interval [8]. The ABEM Terrameter LS2 is set up to measure resistivity and induced polarization at the same time during data gathering.…”

Identifying potential groundwater is crucial, especially in the area that faced water stress issue. Geophysical surveys are one of the most reliable ways to find a groundwater supply. However, when performing a resistivity survey, there is uncertainty in distinguishing between soil particles and groundwater. Therefore, this study combines the electrical resistivity and induced polarization method to distinguish the saturated zones between an aquifer and unconsolidated sediments and the results were validated with borehole data. The pole-dipole array was used to build up two resistivity survey lines. According to the results of the 2-D resistivity and IP survey, low resistivity values between 10 and 100 m (Ohm-m) and low chargeability values between 0 and 1 millisecond can be used to identify potential groundwater areas in the subsurface (msec). Silty sand and sandy clay make up alluvium, which has a resistivity range of 125 to 255 m and a chargeability range of 7 to 10 msec. The reflection coefficient (Rc) values generally range between 0.41 and 0.70 and suggest a highly fractured formation with respect to the hardrocks. A comparison between the depth to bedrock as predicted by electrical resistivity tomography (ERT) and the borehole logs was in strong agreement with the correlation coefficient value (R 2 = 0.9478). On the other hand, the study revealed a relatively week correlation (R 2 = 0.4351) between the final drilled depth and the borehole yield. The study therefore has demonstrated the efficacy of the ERT and IP technique as a tool in delineating groundwater potential zones for the drilling of boreholes.

“…2D ERT has been found to be more efficient in various studies like hydrogeological study, ground water exploration, geotechnical site investigation, environmental assessment and archaeological site investigation (Abu-Zeid et al, 2004;Aristodemou & Thomas-Betts, 2000;Awang et al, 2016;Cassiani et al, 2006;Chambers et al, 2006;Dahlin & Zhou, 2004;Drahor et al, 2008;Lesparre et al, 2016;Loke & Lane Jr, 2004;Mansoor & Slater, 2007;Marsan et al, 2017;Martínez-Pagán et al, 2009;Metwaly & AlFouzan, 2013;Mojica et al, 2017;Stan et al, 2017;Yeh et al, 2002). Application of electrical resistivity imaging in realm of mineral exploration is also found to be efficient and effective (Beauvais et al, 1999;Cardimona, 2002;Chambers.…”

Evaluations of a mineral resource are necessary for mineral rights, owners and investors alike. However, for resource evaluation the detail documentation of subsurface geological spatial distribution such as lateral and vertical extent of bedrock and topsoil, hydrogeological investigation and boulder characterisation is mandatory. Boulder is hard and crystalline compact rock block, which substantial presence in a deposit highly influence the drilling equipment selection. A traditional exploration technique particularly for granite resource evaluation is drilling. But even finite number of drilling sample fails in the accurate delineation of boulders because drilling is limited to small point and rock mass is heterogenous and thus immense portion of the deposit via drilling method remain discern. 2D electrical resistivity imaging (2D ERT) technique of the study area over an area of 3.5 km 2 was accomplished by six resistivity lines using a Schlumberger protocol with inner and outer electrode spacing of 5 m and 10 m respectively. Inverted resistivity images successfully identify the existence of boulders in the area of investigation in the topsoil region; characterized by high resistivity values more than 2400 Ω.m. Whereas, only one core log (BH3) out of three reported presence of boulders. Thus, the research study presented in this paper enables us to conclude that the combined application of borehole and ERT allows us to derive that 2D ERT enhances the resource evaluation efficiency and reduces the cost considerably for underlying subsurface geological characterization.
