The Nigerian tar sand has an immense potential as an additional hydrocarbon based energy resource in Nigeria. Tar sand produces synthetic crude oil which if combined with Nigeria conventional crude oil will prolong the life span of the latter. There is a vast extensive deposit of tar sands in Ondo, Ogun, Edo and parts of Lagos States of Nigeria, stretching across the belt of 120km with consistently high oil saturation. ICP-ES technique was employed for the determination of the major oxides and trace elements concentration in the tar sands samples collected at Imeri, Ogun State, Physical properties such as porosity, bulk density and electrical resistivity were also determined using simple Experimental approach. The results of the porosity ranges from 0.10 - 0.50, bulk density ranges from 1.13 - 1.46 and electrical resistivity ranges from 00.00 - 78.43.Results were also compared with those of previous works who used PIXE-PIGME techniques at Agbabu area and adequate comments were made on the comparison. The results had been able to confirm that Nigerian tar sands could be rich in silica (SiO), which are great assets because of their various industrial applications and utilization. Sulfur and carbon were absent in the tar sand samples collected at Imeri which also make the tar sands differs with that of Ondo State. It was recommended that, Deeper depths could be drilled to ascertain the presence of other potential / economical elements in the study area and water analysis should be carried out on the water at the tar sand deposit.
