Die Bedeutung von OSL-Datierungen feinkörniger Sande für

The study of the outcropping glacial sediments of Stolzenhagen combines detailed sedimentological analyses with modern radiometric dating techniques based on Optical Stimulated Luminescence (OSL). This allows not only to interpret the processes of sediment accumulation and erosion but also to discuss the timing of these processes in a wider stratigraphic context. In result, a model of local landscape evolution and the controlling environmental and climatic triggers for the last 150 kyrs has been developed. In particular, the new datings, which are the first of this type from northeastern Brandenburg for the study period, lead to a revision of previous views on major regional sand accumulation periods. With these data it is now possible to distinguish between Weichselian and Saalian sand accumulation, resulting in a better understanding of the intensity of morphological processes during the last and penultimate glaciations. In addition to the scientific value, this study is a good example for a successful co-operation of local private efforts to preserve an important geological outcrop not only for educational and touristic purposes but also for scientific institutions that accomplish detailed investigations providing new views on environmental changes
