dc.description.abstractGeological mapping and Electrical resistivity soundings were carried out in Kakara village in Gezawa Local Government of Kano State, in order to delineate the geological boundary between the Basement Complex and the Sedimentary rock. The area is a contact zone between sedimentary rock of Chad formation and basement complex rock of Northern Nigeria. Twenty four (24) vertical electrical soundings (VES) were performed along two profiles A and B, adopting Schlumberger electrode configuration with half current separation (AB/2) varying from 1.5m to 70.0m. The geological mapping of the area shows that the area is characterized by two rock types basement complex (granite) and Chad formation (which is a sequence of sand and clay). Interpretation was performed using computer software IX1D, the observed rocks during the geological mapping and borehole data drilled close to the study area was used to correlate the resistivity value obtained in order to arrive at the interpretation. The study reveals the presence of subsurface contact between the two rocks, with chad formation laying uncomformably on the basement rock. The thickness of the uncomformity ranges from 0.993m to 26.930m. Geoelectric map was obtained using the resistivity of the first layer of all the VES points, the geoelectric boundary between the two rock formations and laterite was clearly delineated on the map. Considering the pore volume and permeability of sand lithology, VES A9, A10 and B6 with the highest thickness of sand lithology of 26.66m, 26.93m and 18.42m respectively are the best positions to drill a productive borehole which will be an advantage to Kakara Community which vi has no pipe borne water, the study is also useful in siting engineering structures as sand and clay has very low load bearing capacity.en_US
