6. 0 Conclusions
This paper is a systematic review of geophysical research conducted in the Bosumtwi Impact Crater from 2000 to the present. The trend shows that many articles were published around the periods when the internationally funded Bosumtwi Drilling Project was undertaken. The paper provides an overall understanding of the geophysical methods utilised in the Bosumtwi Impact Crater. The following geophysical techniques were essential in the identification and study of the Bosumtwi Impact Crater: magnetic, gravity, seismic, electrical resistivity, GPR, petrophysical, remote sensing and radiometric methods. The magnetic method was used more than any other method to confirm the circular nature of the impact crater. Beyond the circular geophysical anomalies, petrophysical studies and measurements on cores from boreholes drilled in the crater show the physical properties of breccia, meta-graywackes and slate/phyllites. These observations confirm the presence of shock-metamorphosed rocks.
The under-representation of Ghanaian geophysical researchers on the list of published articles on the Bousmtwi Impact Crater can be primarily blamed on the lack of funding by the Government of Ghana in science research. The direct consequence is that the situation has caused a lack of geophysical studies on areas such as geohazards within the Bosumtwi Impact Crater, which should be of primary interest moving forward. Furthermore, the paucity of research in this area could mean scant knowledge of potential disasters and loss of human lives and livelihood in the future.
