dc.description.abstractABSTRACT A systematic and dedicated effort has been made to collect two-dimensional resistivity data of the subsurface formation of a sewage treatment site on Ahmadu Bello University main campus, Samaru, Zaria, Kaduna State of Nigeria, for research study. The Research site is located within the South-West region of the main campus, between latitude 7.6570N to 7.6590N and longitude 11.1350 E to 11.1390 E, and part of the Kubanni Basin underlain by Precambrian rocks of the Nigerian basement complex. The main aim of the study is to use the two-dimensional Wenner based configuration electrical resistivity tomography (ERT) technique to characterize the subsurface lithology of the site. Electrical resistivity tomography method is based on the measurements of electrical resistivity along a profile, where a series of electrodes (smart electrodes) are regularly placed. In all, geo-electrical surveys were carried out on a total of six profiles, two of equal length of 300m each and the remaining four, 200m each long. The measured resistivity data were used to deduce the true resistivity variation of the subsurface formation and related to geological features or materials. The interpretation of the two dimensional pseudo sections showed averagely top deposits or overburden thickness varying between 4m and 15m. The depth to weathered basement rocks varies from about 4m to over 20m underneath some parts of the sections. The fractured basement rock occurred averagely from depth above 15m, while fresh basement rock was encountered averagely from depth of 25m. Structural viii features suspected to be fault, that may serve as conduit for passage of waste were also identified, particularly on model sections of profiles LundDam01 and LundDam02.en_US
