Subsurface Investigation of Basement Structures Using Electrical Resistivity Methods at Zainawa Village Kano, Nigeria

Electrical Resistivity Methods involving Schlumberger Vertical Sounding (VES) and Wenner Profiling (EP) were carried out to map the Geological features of earth subsurface in Zainawa Area Kano State, Nigeria. Five profiles established; consist six (6) VES points at each profile. GEOPULSE resistivity meter (SAS 300) was used for data acquisition. The field obtained have been analyzed using computer software (IPI2win) which gives an automatic interpretation apparent resistivity. A maximum three geoelectric layers delineated from master curves. section beneath study area composed top soil (clayey-sandy sandy-lateritic), weathered layer, partly (fractured basement) fresh basement. value topsoil layer varies 20 Ωm 600 with thickness ranging 0.5 7.2 m. basement has values 15 593 between 2.75 33.04 fractured 201 835 11 20.4 (bedrock) 1161 3115 infinite depth. depth produced give a good picture topography within area. ranges m around 01 85 25 also reveals linear structures (VES 05, 21, 22 23) trends NE-SW direction.
