Abstract
This study provides a comprehensive summary of current knowledge about the German–Polish Caledonides, integrating geological and geophysical data to refine our understanding of the Thor Suture between Avalonia and Baltica. Using reinterpretation of the Basin-9601 seismic profile and a newly constructed 2D forward gravity model, alongside compiled gravity and magnetic data from eastern Germany and western Poland, we examined the main crustal boundaries. The results reveal that the Caledonian Deformation Front marks the northern limit of a thin-skinned fold-and-thrust belt. Near Rügen, this belt consists of Ordovician metasediments derived from the Caledonian accretionary wedge. In Poland, the Pomeranian Caledonides comprise deformed sediments from the Caledonian foreland basin, which were incorporated into the orogenic wedge. The Thor Suture, identified as the thrust of Avalonia's crystalline basement over Baltica, lies c. 120 km farther south. It extends beneath the North German Basin's depocentre and follows the Dolsk Fault Zone in western Poland. The lower crustal edge of Baltica is underthrust southward to the Flechtingen High in Germany, reaching the Variscan Rheno-Hercynian suture at the margin of the Bohemian Massif. The Thor Suture aligns with a lithospheric mantle necking zone, where the thick lithosphere of Baltica transitions to the thinner lithosphere of Avalonia.
