Electrical resistivity tomography (ERT) and vertical electrical sounding (VES) techniques were employed to assess the hydrogeological structures and groundwater potential of the Obudu Basement Complex. The Wenner electrode configuration was used to acquire the ERT data along 4 profiles, while the Schlumberger configuration was employed in the VES investigation, where 30 locations were occupied during the data acquisition campaign. Results show that rock distribution is predominantly the granite gneiss series that are considerably weathered in several locations especially within the western portion of the study area. Three potential hydrogeological scenarios were identified from three of the ERT profiles. These include the regolith-, doleritic- and kaolin-induced groundwater conduits. Within the central segment of the study area, transtensional stress regimes traceable to the neo-Proterozoic syn-orogenic event were observed to have resulted in the establishment of some regional fault systems. Over time, several episodes of minor tectonic events have resulted in cataclastic deformation of the gneissic rocks, creating pathways for groundwater circulation. Additionally, it was observed that dolerite intrusion in some locations cataclastically deformed the host rock resulting in syn-emplacement fractures that can create pathways for groundwater to flow. Saprolite units and locations within major fault lines were inferred to have moderate to good groundwater potential due to their large width and the presence of multiple interconnected fractures as inferred from the pseudo-sections and lineament map. More so, streams and rivers within these areas can infiltrate through the pathways created by the faults, hence increasing groundwater circulation within the conduits.

电阻层析成像（ERT）和垂直电测深（VES）技术用于评估奥布杜地下室综合体的水文地质结构和地下水潜力。Wenner电极配置用于沿4个剖面采集ERT数据，而Schlumberger配置用于VES调查中，在数据采集活动中占据了30个位置。结果表明，岩石分布主要是花岗岩片麻岩系列，在几个位置，特别是在研究区域的西部，风化程度很高。从三个ERT剖面中确定了三个潜在的水文地质情况。这些包括由雷哥石，白云母和高岭土引起的地下水管道。在研究区域的中心部分，可以追溯到新元古代同造山事件的超张应力体系导致建立了一些区域断层系统。随着时间的流逝，几次轻微的构造事件已经导致片麻岩岩石的碎裂变形，为地下水循环创造了通道。此外，据观察，在某些位置的白云石侵入使基质岩发生了裂变，从而导致同位裂隙，从而为地下水流动创造了通道。据推测，主要断层线中的腐殖质单元和位置具有中等至良好的地下水潜力，这是由于其较大的宽度以及从假断面和构造图上推断出的多个相互连接的裂缝的存在。更是如此
