| Abstract: | Affected by the shifting Intertropical Convergence Zone, Lake Malawi holds an outstanding limnic sediment archive storing palaeo-environmental information of a climatically highly responsive landscape in the East African Rift Valley. Reliable chronological data are essential to interpret the lake-bottom sediments and optically stimulated luminescence (OSL) dating is an important method to build up the chronology. We report on material-property studies and OSL-dating results for polymineral fine grains extracted from piston cores obtained from the northern basin of Lake Malawi during the 1998 campaign of the International Decade of the East African Lakes (IDEAL). OSL-dating is based on a post-IR blue (pIRB) light stimulation single aliquot regeneration (SAR) protocol. Our results support earlier publications demonstrating the general applicability of OSL-dating on Lake Malawi sediments of Holocene and late Pleistocene age. However, the study also shows that dose rate estimations imply major challenges which need to be investigated in more detail to improve future OSL-dating results. |
