Abstract: Anomalies observed on gravity maps of sedimentary basins are the integrated effects of faults, folds and intrusive bodies of basement or intra sedimentary origin. By computing a 2-D Cross Correlation Function (CCF) between the gravity data and the gravity anomaly due to a step structure, normal and reverse faults can be mapped from elongated contours of maxima and minima in the CCF map. The method was employed to map faults in part of the Benue trough, Nigeria. Some of the faults identified correlate well with known faults shown on the regional structural map of Nigeria. Although the status of the unconfirmed faults can only be ascertained through field investigations, the dominant N-S, NE-SW and E-W strike directions fit into the general pattern of strike slip tectonic features and mineralized zones associated with the trough.
