Integration Of Ground Magnetic And Frequency Domain Electromagnetic Data, A Case Study From Nkwanta And Asuogya In The Western Region

ABSTRACT Ground magnetics and electromagnetic datasets were processed to interpret the subsurface geology and structure of the southwest of Ghana within the Tarkwain and Volcanics in the central part of the Ashanti belt. The study was aimed at mapping lithology, delineating structural lineaments and their trends as well as the trend of mineralization in the study areas. The data processing steps involved enhancement filters such as reduction to the pole, analytical signal, the first horizontal and vertical derivative, reduced to equator and upward continuation all of which helped delineate zo…
