Abstract

3D Moho interface has been computed from the airborne Bouguer anomaly beneath the southern part of the Benue Trough (BT), using the MATLAB program 3DINVER.M. From the study, the maximum Moho depth of 27.5 km and the minimum Moho depth of 18.1 km were computed. Interpretation of the gravity data of the southern part of the BT suggests that igneous input contributed greatly to the understanding of its concomitant deep crustal processes. The Moho depth elevation from the area is calculated to be around 9.4 km. This is in agreement with the Moho uplift within the study region as suggested by earlier researchers.

Key words: Lower Benue trough, crust, mantle, bouguer gravity data, 3DINVER.M.
