Some key problems of the pre-Permian tectonics of Poland

摘要: Four tectonostratigraphic terranes have been distinguished outside the edge of East European Craton (EEC) in Poland (Fig. 1a) on a map by W. Pozaryski and P. Karnkowski (1992) et al. (1992). Two them (Pomeranian Łysogory Terranes) are questioned present authors. These areas rather parts EEC passive margin (miogeocline), deformed Late Caledonian limes into fold-and-thrust bell 1b).
