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.
