| dc.description.abstract | Integrated airborne geophysical methods namely magnetic and radiometric were used to investigate the Konongo mining area located at the north-eastern boundary of the prospective Ashanti Gold Belt in south-eastern Ghana. These datasets provided useful information on the lithology and geological structures within the area. The geophysics data processing approach employed concentrated on enhancing the geophysical data quality and this aided in tracing accurate positioning of geological boundaries, the responses related to mineralization and geological structures that may be of vital economic importance. The magnetic image enhancing technique such as reduction to the pole, analytic signal and first vertical derivative helped delineate folds, fractures, tectonic boundaries and the D 1-NE /D2-NNW structural deformation events which are potential hydrothermal fluid traps. The Birimian Meta-sedimentary and meta-volcanic rocks noted to host gold mineralization and other metal ores in the Belt were also delineated. The radiometric data provided geochemical information of potassium (K), thorium (Th) and uranium (U) that proved valuable in delineating bedrock lithology of the area such as the Banso Batholith, Birimian meta-volcanics, Tarkwaian Formation and alteration zones within the area and contact zones. High K, Th and U concentration were mapped in the meta-sediments and the Banso Batholith. The high-resolution airborne magnetic and radiometric data of the study area resulted in better definition of both geological structures and lithological boundaries. This project shows the usefulness of geophysical data in mapping possible geological structures that host hydrothermal gold mineralization. | en_US |
