Large scale magnetic susceptibility soil mapping: a proxy for geological mapping and exploration from Bogoso (Ghana)

Abstract : This paper describes the use of magnetic susceptibility measurements on a set of nearly 3000 soil samples (one sample per km(2)) collected for geochemical analyses within the framework of a geological mapping program in Ghana. The result is a map of soil magnetic susceptibility which has been compared with other maps. There is a good consistency with geological domains and lithologies, as well as with some of the geochemical soil analyses and also partly with the aeromagnetic data. In the tropical, deeply weathered lateritic context of the study area, soil magnetic susceptibility reveals similarities with magnetic and/or geochemical survey results, suggesting this rapid and easy to use technique can be an effective tool for exploration and geological mapping programs.
