This thesis presents new geological, structural and metamorphic maps for the Palaeoproterozoic Sefwi Greenstone Belt of SW Ghana in the West African Craton. It explores characteristics unique to new crustal material made two billion years ago and elucidates the contrasting mechanisms and processes of crustal growth and mountain building early in the Earth's history. With this research, we are better able to understand evolutionary changes in the plate tectonic processes that have shaped the Earth as we know it today.
