Struktura i ewolucja polskiej części północno-zachodniego trzeciorzędowego basenu europejskiego

Abstract

STRUCTURE AND EVOLUTION OF POLISH PART OF NW EUROPEAN TERTIARY BASIN Summary Two main paleogeographic areas from the Tertiary times may be differentiated in Poland: a smaller, Alpine geosynclinal area connected with the Paratethys and Tethys and occupying southern part of the country, and larger, epicontinental area occupying central and northern Poland. The present paper deals with the paleogeographic setting of the epicontinental Tertiary basin of PoIand which was characterized by the geocratonic conditions, i.e. the predominance of continental-fades deposits upon marine ones, and of denudation upon sedimentation. Outside the Tethys, two large sedimentary basins existed in the Tertiary Europe: (1) north-western European basin, and (2) south-eastern European basin. The general framework of these basins was shaped by Variscan movements. The boundary between these basins was passing through Poland and the interfingering of facies typical of these basins is found here. Thus, Poland is the key area for direct correlation of their sedimentary profiles.
