APPLICATION OF AIRBORNE AND GROUND GEOPHYSICAL DATA FOR AQUIFER INVESTIGATION IN OMOGBARA
Abstract
Airborne geophysical surveys have the ability to cover large areas quickly with minimal impacts to local activities and the environment. Airborne magnetic shows that fracture and fault consist the aquifer in the study area, areas with low magnetic values (- 111.51 nT) interpreted as geological structure. In order to increase the perceptibility of magnetic bodies that might be related to the bodies of interest, enhancement techniques such as reduction to equator, tilt derivative and horizontal derivative tilt derivative were applied. They all increase the visibility of structural features, and also show that the structural features align in NE-SW direction representing Pan African orogeny associated with the study area. Spectral analysis was applied to magnetic data to estimate the depth to aquifer, the estimated depth ranging from 20 to 100 m.
Time domain airborne electromagnetic results show some conductive zones; these zones were interpreted as linear structure. The result of Aeromagnetic and Airborne electromagnetic (AEM) were correlative. It shows that low magnetic anomaly (
