Abstract

This work is an addition to our previous effort on the tar sand deposits in southwestern, Nigeria. Electrical resistivity sounding and profiling using Schlumberger and Wenner array configuration were used to determine the nature and depth of occurrence of the tar sand unit. Core description of five boreholes in and around the study area was exploited for regional correlation of the tar sand horizon. The tar sand at Itele has a resistivity value of ~900Om to >1480Om with an average thickness of ~30m. Visual inspection of the cores from the study area shows that the lithology of the tar horizon is essentially muddy, non-fissile, fine-grained sand. In addition, the tar sand of the area belongs to the high resistivity facies identified by previous workers in the Ogun state axis of the tar sand belt.
