After a brief review of the structure, the stratigraphy and the facies of the Rumanian eastern Carpathians flysch zone, the authors analyse the main paleocurrent directions on the internal facies of the paleogene flysch. The most important and numerous currents were longitudinal and came into the flysch trough from an outlet area situated in the Carpathian arc region. For this reason it is inferred that the principal source of detrital material was represented by the Pannonian–Transylvanian internal massif.The crystalline core of the eastern Carpathians furnished only a small quantity of clastics, which were transported into the trench by means of transversal, relatively weak currents. The role of different structural elements (platforms, cordilleras, internal massifs) in providing detrital material is briefly discussed. Finally, an attempt is made to outline the paleogeographic evolution of the eastern Carpathians during the Paleogene.

Abstract The azimuths of cross-strata and current markings in individual sedimentation units within the Upper Precambrian flysch of Dobrogea, Romania have been mapped, separately. Although discrepancies of up to 86 degrees have been found, the azimuths of these two ...

Abstract The concept of flysch as an orogenic facies cannot be applied to all flysch-type deposits without discrimination. The tectonic environment of the Alpine flysch does not represent a unique model. The definition of flysch must accentuate its concrete ...
