Lake Bosumtwi (a meteorite impact structure in Ghana) located in the tension field of competing North African Monsoon and the Harmattan (dry and dusty winds from the Sahara) provides a benchmark record for climatic and environmental change in an area that is considered to be a part of the cradle region of anatomically modern humans in Northern Africa. Yet, no age model is available that spans beyond the Upper Pleistocene, although the record dates back 1.07 million years. Based on well-defined and pronounced cyclicity in borehole logging data, we aim to develop an age-depth model for lake Bosumtwi and to place the timing of dust input dynamics into a climatic concept.
