Application of Thorium Normalization Technique to the Airborne Radiometric Data of Some Parts of the Central Benue Trough (CBT) Nigeria, for Possible Hydrocarbon Accumulation

A new hydrocarbon exploratory technique namely; Thorium Normalization is applied on the aero geophysical data (radiometric) of some parts of the central Benue Trough to delineate areas of possible hydrocarbon accumulation. This technique is considered very significant because, it identifies areas with probable hydrocarbon presence in sedimentary basins. Separation of radioelement measurements and estimation of the characteristics statistics over each lithological units were determined. The statistical process carried out on the radioactive elements of thorium, potassium and uranium (eTh, %K and eU) of the area displayed low coefficient of variability (CV%) for the three radioelements, depicting higher degree of homogeneity.
