Abstract

This thesis provides a local to global perspective on the evolution of an ancient mountain chain in West Africa, which formed more than 2 billion years ago. Based on new and published data, it is argued that it formed through plate tectonic processes not different from those that characterizes the modern Earth. It also played an important role in the cyclic breakup and assembly of large supercontinents. The evolution of the mountain chain coincided with important changes in Earth's surface environment, and it is further argued that these were coupled through the cyclic deposition and uplift-erosion of sedimentary successions.
