Summary According to the terrane model used for the interpretation of the heterogeneities in the Lower Palaeozoic development along the southwestern border of the East European platform (Baltica) several suspect terranes have been accreted to the passive platform margin during the closure of the postulated Tornquist Sea in Ordovician and Silurian times. Their final docking and partly overthrusting onto the platform are of Scandian (Early Devonian) age. A matter of dispute is the provenance of the various terranes. There are lithofacies, structural, palaeobiogeographical and palaeomagnetic constraints for relations both to Baltica and East Avalonia. Specific similarities can be observed between the Southern Jylland, Pomerania, Łysogóry (including Radom-Krasńik), and Rawa Russkaja terranes. After their accretion and amalgamation they may form a more or less continuous Caledonian marginal thrust belt along the platform border. On the other hand, more significant differences exist between the latter and the so far recognized Southern North Sea, Małopolska, Cracovides, Upper Silesian, Sudeten, Kochanowka, and Dobrogean terranes. The position of any Tornquist Sea suture zone(s) is still completely enigmatic.
