dc.description.abstractDigital magnetic data were extracted from existing half-degree Aeromagnetic map of DANGE (Sheet 29) within the Sokoto Basin. The sheet is characterized by a prominent E-W negative anomaly with a magnetic relief of 330 gammas and aligned along latitude 12°49'. This major E-W Anomaly was flanked on both sides by magnetic highs. A 3-D inversion technique was employed to interpret the "Dange magnetic Anomaly". A best-fit model was obtained which is represented by a prismatic body having dimensions (10.11 x 2.94 x 3.32) km3. The causative body was interpreted as an intrabasement body made up of basic igneous rocks with a high magnetic susceptibility of 0.0730 (SI Units). It is concluded that the-geodynamic process of the emplacement of the body are penetration by diapiric intrusion of mantle rocks followed by ascention to the lower and upper crust which on cooling forced a downward deflection of the crust by virtue of its increased density.en_US
