Characterization of Regolith Types and its Impact on Gold Anomaly in Highly Weathered Terrains Using Multiple Dataset

Abstract

Contribution/Originality: This study documents that regolith environments have huge influence on surface gold expressions and anomaly definition. Regolith-based geochemical interpretation is effective to account for each regolithic effect. Each regolith type has equal tendency of hosting realistic anomaly when equal weight of importance is accorded to them. INTRODUCTIONIncessant climatic changes over the years have extensively affected most terrains in Ghana, predominantly the savannah areas and some tropical rainforests resulting in the present complex landforms (Arhin and Nude, 2009). The associated weathering processes and regolith landform evolutions post exploration challenges. Furthermore, these processes may co-exist with other geologic processes such as the deposition of post-mineralization materials to offset or obscure mineralization and impose exploration challenges (Arndt et al., 2017).
