Abstract

This work was carried out in Karuga - Karji Area of Kamazou, in Chikun Local Government Area, Kaduna State. The area is approximately located within longitudes 7° 490' 034”E and 7o491’428”E and Latitudes 10°487'579" N  and 10o487’900”N and it is about 800m South West of Kaduna on Patrick Ibrahim Yakowa Road. The total area covered in this work measures about 8400m2. The study is important because there was no any record to show that geophysical survey has been done in this area. Therefore, Geophysical survey in terms of Geoelectrical resistivity sounding using the Schlumberger array was adopted – sixteen vertical electrical soundings (VES’s) were measured on the study area.  The work was aimed on investigation of the aquifer variation of electrical resistivity of the subterranean section of the study area.  Quantitative and qualitative Interpretations of data were carried out. Four profiles with four VES points on each profile of the geoelectric sections revealed that;   profile 1 is about 0.105km long. The azimuth of the profile is west – east, with maximum of five geoelctric layers. The soundings were at the lowest and the highest resistivity of 95.59485 Ω-m and 85628.634 Ω-m. Profile 2 is about 0.105km long. The azimuth of the profile is west – east, with maximum of four geoelctric layers at lowest and highest resistivity of 138.57857 Ω-m and 404.61882 Ω-m. Profile 3 is about 0.105km long. The azimuth of the profile is west – east, with maximum of four geoelctric layers at lowest and highest resistivity of 83.82933 Ω-m and 269.84367 Ω-m. And Profile 4 is about 0.105km long. The azimuth of the profile is west – east, with maximum of five geoelctric layers at lowest and highest resistivity of 115.0464 Ω-m and 6869.11 Ω-m. The geologic sections correspondingly indicated the lithological variability compositions of the depths delineated. The characteristic resistivity formed for the various earth materials found  alluded that the  layers of the study area is composed of lateritic sands, weathered rocks, quartzite alluvium, clay, fractured and fresh basement rocks. The fouth VES point geoelectrical layer is considered the suitable aquifer for the area under investigation with moderate electrical resistivity value (115.0464 ohm.m), and could be recognized sometimes as the most extreme 18.6m depth of penetration. At the maximum depth of penetration of this area, the lower layer (fourth layer) was recognized with the highest electrical resistivity value (85628.634 ohm.m)   The thickness of the over-burden is observed having no uniformity in the profiles. Profile 2 is the deepest zone within the study area with an average of 27.9m depth.

A maximum of five geoelectric layers were identified in the study area. The basement is resistive with variable resistivity values ranges from 38.1 Ω-m to 7029.4 Ω-m.  The geologic sections of the rocks formed from the terrain is the weathered/fractured basement aquifer overburden the study area.
