The Peribaltic Group
International Field Symposium on Quaternary Geology of Denmark
August 29 – September 3, 2000,
University of Aarhus, Denmark

Organisers:

This year`s symposium of the Peribaltic Group was held at the westernmost fringe of the Baltic Sea basin to give the participants a synopsis of Quaternary geology in an area far away from Estonia, where the Group has met last in May 1999. The symposium consisted of one paper/poster session day and four days of field excursion. At the paper session, 20 presentations were given including keynote addresses of K.L. Knudsen, M.S. Seidenkrantz and an overview presentation of M. Houmark-Nielsen. Seven posters were displayed. Accommodation was at the field station of the Department of Earth Sciences in northern Jutland and at the conference centre of the University of Aarhus in Sandbjerg, southern Jutland. Symposium materials include abstract volume (58 pages) and excursion guide (32 pages) available upon request from Jan Piotrowski.

The field trip took us to some classical as well as entirely new sites in Jutland and the islands of Mors, Langeland, Møn and Fyn. On day one we visited the newly discovered cliff section at Knud Strand where Elsterian through Weichselian sediments are exposed in one section including Holsteinian and Eemian (terrestrial and marine) sediments, the cliff section at Kås Hoved with the possibly longest exposed Holsteinian marine section in Europe, and the spectacular cross-section through the Main Stationary Line at Bovbjerg at the west coast of Jutland. On the second day we looked at the Weichselian (glaciotectonised) and Holocene sediment sequence at Lønstrup Klint, and at the Skærbæk cliff on Mors exhibiting large-scale glaciotectonic deformations (also of the Tertiary substratum) in a Weichselian end moraine complex. While driving to southern Jutland on day three we looked at the morphology of the Main Stationary Line and discussed the controversial origin of numerous deep channels interpreted by some as subglacial tunnel valleys. In the afternoon we examined Saalian, Eemian and Weichselian (early Weichselian till??) succession at Emmerlev cliff on the west coast close to the German border and the Stensingmose cliff on the north shore of the Flensburg Fjord with Saalian, Eemian (marine Cyprina clay and Tapes sand) and Weichselian deposits, partly disturbed due to the glaciotectonics. On the last day we looked at the classical section of Ristinge cliff where a spectacular glaciotectonic setting with over 30 thrust slices including the Eemian deposits are exposed. After hopping from one island to another we reached Copenhagen, where most participants left at the airport. Then a long drive back to Aarhus and symposium end around 10 p.m. there.
