Geophysical resistivity technique; vertical electrical sounding (VES)/earth resistivity test (ERT) was carefully done at 35 locations in a hard rock terrain of Tamil Nadu, India to evaluate natural resources such as groundwater, economic mineral deposits, etc., Data acquisition was done by CRM-500 Aquameter along with GPS, topographic map, Brunton compass, measuring tape, field notebook, hammer, iron rods (electrodes), and batteries. Furthermore, the major four subsurface layers' thickness, resistivity, and pseudo-section profiles were identified from the resistivity dataset using IPI2WIN. The resistivity curve type is also evaluated from the consecutive subsurface layers' resistivities. These can be helpful in groundwater potential zone identification studies. The entire dataset from this research can be useful in groundwater exploration, management, economic mineral exploration, waste disposal sites, reservoir, and dam site selections, and identifying the structural controls such as fractures, joints, buried anticlines, etc., The data also can be coupled with other regional geological and geophysical datasets for many natural resource exploration and exploitation studies.
地球物理电阻率技术；在印度泰米尔纳德邦的硬岩地形中的35个地点仔细进行了垂向电测深（VES）/大地电阻率测试（ERT），以评估诸如地下水、经济矿产矿床等自然资源。数据采集通过CRM - 500水质仪结合GPS、地形图、布伦顿罗盘、卷尺、野外笔记本、锤子、铁棒（电极）和电池完成。此外，使用IPI2WIN从电阻率数据集中识别出主要的四个地下层的厚度、电阻率和视电阻率剖面图。还根据连续地下层的电阻率评估电阻率曲线类型。这些对于地下水潜在区域识别研究可能会有帮助。本研究的整个数据集可用于地下水勘探、管理、经济矿产勘探、废物处理场地、水库和坝址选择，以及识别诸如裂缝、节理、埋藏背斜等构造控制。该数据还可与其他区域地质和地球物理数据集相结合用于许多自然资源勘探和开发研究。
