摘要：Geo resistivity of sounding of Bangriposi block was conducted to delineating the groundwater feasibility and selection of site for installation of bore wells.The reason for choosing this area is due to the poor and backward inhabitants residing in the locality. 2D resistivity imaging technique was utilized. The 2-D resistivity imaging technique utilized the Schlumberger electrode array configuration because this array is moderately sensitive to both horizontal and vertical structures. Eighteen (18) Vertical electrical resistivity soundings were acquired with Geo Resistivity Meter in Schlumberger configuration. The electrode spacing AB/2 was varied from 1.5 to maximum spread length of 100 m. The interpretation of resistivity curve is done by JESIX software. Four distinct subsurface geologic layers were identified, aided by borehole lithological logs. These include; the topsoil, Over burden, Weathered and Fractured layer.The top soil layer of variable nature has resistivity value between 16to464 ohm.mt, whose thickness is ranging from 1 to 2.5 m.Over burden zone containing sandy soil and lateritic soil with resistivity value ranging from 78 to 250 ohm.mt whose thickness is 3.1 to .After investigation we find that all points are suitable for Bore well. Most of the feasible sites are fractured granite. Rock type of study area are Granite, Quartzite and Granite gness. Taking in view of VES interpretation and Strata of Exploration drilling, the Bangriposi block is consider for feasibility of Bore Wells.
