The Caledonian deformed ordovician of the Rügen area -sediment provenance and tectonic studies

Summary The Ordovician of the Rügen area shows no affinities with that of the adjacent regions of the East European Platform, situated immediately to the north (i.e. Bornholm and Skåne). By contrast, the detritus in the sandstones and greywackes points to an active continental margin in the southwest, along the southern border of the suspect Tornquist Ocean (i.e. northern Peri-Gondwana). Deformation features can be assigned to Caledonian tectonic events. The more than 3 km thick pile comprises a stacked wedge complex, which was emplaced against and onto the southwestern border of Baltica.
