Abstract : Aeromagnetic data from the Lau and Dong regions of Nigeria's Upper Benue Trough were examined in order to assess prospective mineralization zones, estimate sedimentary thickness, and assess hydrocarbon potential. Using polynomial fitting, the residual anomaly field was obtained by subtracting the regional anomaly from the total magnetic intensity field (TMI). A variety of magnetic anomalies are visible in the residual intensity and total magnetic intensity fields, indicating that the research area is magnetically diverse. The sedimentary thickness, which varied from roughly 316.5 to 3716.0 m, was estimated using the Source Parameter Imaging (SPI) approach. Susceptibility values ranged from 0.0001 to 0.5275 units, with corresponding depths ranging from 152 to 2578 m, according to forward and inverse magnetic modelling. Sandstone, gabbro, gneiss, marble, granite, limestone, and shale are among the lithologies that may be present, according to the modelling results and magnetic signatures. These lithological units indicate an environment that is conducive to the accumulation of minerals and could facilitate a number of industrial uses. Additionally, the greatest sedimentary thickness of 3716.0 m indicates favorable circumstances for the production and deposit of hydrocarbons in the region.
