The stratigraphic, tectonic and organic geochemical development of Lower Benue trough and Anambra basins is similar to the basin of Sudan, Chad and Niger Republic where oil has been discovered. In addition, coal is mined in some parts of the study area (Ankpa), in some villages such as Okobo, Odagbo, Agumagu, Onupi, Awoakpalii, etc. This research work is aimed at modeling and estimating the sedimentary thickness within the area and hence remark on the hydrocarbon, coal and other mineral potential in the area using source parameter imaging (SPI) and forward and inverse modeling method. This will be of great help to the people digging manually to look for those minerals. The depth to the magnetic source/sedimentary thickness ranges from 220.0 to 3705.4 m as revealed by the SPI result. This variation may be as a result of the heterogeneous nature of the earth, intrusive or the different type of bodies within the subsurface. Modeling results depicted that the depth to the magnetic source of 820 m, 4229 m, 1957 m, 406 m, 400 m, 755 m and 4229 m for profiles 1, 2,3, 4, 5, 6 and 7 respectively. The result of forward and inverse modeling method with the susceptibility values showed that there is dominance of sandstone, limestone, granite and slate within the study area, though, susceptibility value is only an indicator which is subject to confirmation by using laboratory analysis and other geophysical methods. The depth obtained favours hydrocarbon accumulation potential in the study area.
