Characterization of (paleo)lacustrine landforms using sedimentological and portable OSL investigations at Schweriner See, north‐eastern Germany

Abstract We investigated four subaerial (paleo)lacustrine landforms at the north‐eastern shoreline of Schweriner See, Germany. These included two beach ridges, one nearshore bar and a silting up sequence located close to fossil cliff, which marks former maximum extent See. used luminescence profiling with SUERC portable OSL device (POSL) on all sediment sequences in combination sedimentological investigations such as grain size, loss‐on‐ignition magnetic susceptibility provide information various formations lacustrine depositional environment. The POSL reader was pre‐treated polymineral samples gain an insight into distribution within individual sequences, but also among sequences. proved valuable understand processes, were not visible lithology or parameters. With somewhat larger uncertainty this method provides relative chronologies Additionally, we carried out radiocarbon dating full optical stimulated (OSL) establish chronological framework. ages be more reliable date ridges setting than samples, severely influenced by reworking.
