Lacustrine archives may provide valuable point-data for studying past climatic and environmental changes. Lake Bosumtwi (Ghana) is of special interest as it recorded such oscillations throughout the last 1.07 million years in a potential key region of human evolution during this period. The prominent climatic- and environmental sensitivity of this geo-archive can be explained by its location on the interface of competing climate agents such as the Hamattan (hot and dusty winds from the Sahara) and the North African Monsoon both being dependent on the Intertropical Convergence Zone. These impacts may translate into diverse and complex ways regarding geo-scientific proxy data. In this context, the temperature dependent magnetic susceptibility k(T) is promising to reflect magnetic-mineralogical changes that may indicate oscillating climatic and diagenetic effects and dust input. To better constrain the effects of all potential affecting parameters, we test a multivariate approach on the last glacial part of Lake Bosumtwi that integrates k(T), the room temperature magnetic susceptibility, its frequency dependency and gamma ray logs. This approach is promising to increase our understanding of all parameters and their interdependency. Thus, we aim to shed new light on the relationship between k(T) and the depositional history of Lake Bosumtwi.
