The Peribaltic Group
Field Symposium on Glacial Geology at the Baltic Sea Coast in Northern Germany
September 7-12, 1997, Kiel, Germany
Organiser: J.A. Piotrowski
36 participants from 9 countries
The Symposium focused on glacial geology and chronology along the German part of the Baltic Sea. The Symposium was attended by 36 participants from 9 countries. At the paper and poster sessions, which were held on Monday (Sept. 9) at the Institute of Geology and Palaeontology of the University of Kiel, 15 oral presentations and 8 posters were given. Lectures were grouped
into regional studies from different sections of the Peribalticum, and into one process-oriented session.
The field excursion which took 5 full days was concentrated on exposures along the Baltic Sea cliff between Eckernforde and the Isle of Rügen, along a distance of some 300 km. Discussed were glacial sedimentary environments, glaciotectonic processes, landform origin, subglacial processes, ice sheet dynamics, stratigraphy and timing of glacial events. One major point of
interest was correlation of events and environments in this part of the Peribalticum during the Weichselian Glaciation in the context of the palaeogeography of the entire Peribaltic area. This is currently the primary area of interest of the Peribaltic Group. Preliminary results of one INQUA
project involving glacial geology at Heiligenhafen (drumlin origin, Weichselian stratigraphy, till sedimentology) were presented. Both the plenary session (program given below) and field presentations were accompanied by lively discussions, which generated new ideas and helped formulate questions for future studies.
The Symposium indicated research demand in the following areas:
1. Correlation of glacial events. In many areas of Northern Germany local stratigraphies exist, which are still difficult to put together into one regional framework.
2. Timing of glacial events. Great deficit exists in absoulte dating of the Pleistocene sedimentary units, which causes further difficulties in stratigraphic interpretations. Even within the Weichselian period, little is known about timing of ice advances (e.g., disputable glaciation during the isotope stage 4).
3. Glacial sedimentary environments. On the excursion, numerous sections were shown which seem to have a similar sedimentary architecture, even though the origin is interpreted differently. Weichselian ice advances were clearly accompanied by water ponding in front of and possibly under the glacier, but a systematic sediment facies interpretation and correlation is still to come.
4. Ice movement directions. Mostly interpreted from till fabric measurements, the ice movement directions present a true mosaic at the local scale, especially in the ice marginal position. An attempt should be made to put these unexpected directions into a context of processes controlling the ice sheet dynamics.
