In search of clay deposit in a dual geological environment in the South-Southern part of Nigeria.

Abstract

The presence of clay deposits in the south-southern part of Nigeria was investigated using the electrical resistivity methods. The Vertical Electrical Sounding (VES) was adopted for the investigation using the Schlumberger electrode arrangement. Resistivity soundings were collected from several locations which were evenly distributed within the study area. Models were generated for computer iterative technique. Borehole data were also collected using spontaneous potential logging method as well as driller's log in some selected sites within the study area so as to correlate surface measurement with borehole records. Analysis based on five depth related resistivity contour maps as well as sellected cross sectional profiles confirm the existing dual regional geological environment of the area. Finally, it was established that the quantity of clay deposits is more in the sedimentary environment than basement complex area.
