    Geological and structural interpretation of South–East Voltaian basin, Ghana, using airborne gravity and magnetic datasets
    (September, 2015. ) Mensah, Victor
    Airborne gravity and magnetic methods were used to interpret the geology of the south eastern Voltaian, Ghana. The study was aimed at mapping lithologies and geological structures responsible for any observed anomaly in the Area. The enhancement filters applied were used to reduce signal–to–noise ratio. The high-resolution airborne gravity and magnetic data delineated the Densubon Sandstone Formation which was permeated by a Mafic subvolcanic intrusion and the Bimbila Formation which was also permeated by a felsic granitic intrusion. The Densubon Sandstone Formation, located at the southern part of the study area and the Bimbila formation also located at the northern part of the basin, were separated by a geological contact which trended NE–SW. The results show that the Voltaian Basin is underlain by the Proterozoic Birimian Supergroup which could be the reason for both the high gravity and magnetic signatures.
