The boundaries between the different litho-structures in the Gombe arm of Benue trough were delineated by interpreting gravity data of the study area using the Analytical signal method. This helped to reveal the potentials in the area. The bouguer and analytical signal maps of the area were produced to show the distribution of the anomalies in the study area. The method displays the gravity anomalies of an area through the amplitudes of the directional analytic signals. The study area showed high anomalies in the northeastern part and southern part of the study area i.e. Dukku and Akko, which was attributed to the presence of metamorphic rocks which caused positive anomalies and sedimentary rocks in the areas which caused the negative anomalies
