The geotectonic events in Late Cretaceous - Early Paleogene interval, caused
essential changes in the architecture of the Tethysian paleogenic sedimentation basins and their rela relationship with the continental source areas. Laramic tectogenetic paroxysm (Maastrich tian/Danian) due to the subductin of the East European craton under the TiszaTisza-Dacia block, plays a double role in the structuralization of the East Carpathian units. In an internal position, the External Dacides are built (The Black Flysch, Baraolt, CeahlCeahlau and Bobu nappes, senso Sandulescu, 1984), and in the external part the Paleogene Foreland basin depozones (equivalent to the "Foreland basin", senso Grasu et al. , The basin worked up to the Lower Miocene, when the styric and moldavic tectogenesis occurred and the Moldavian units were born (from the inner part to the outside are: Marginal Folds Nappe, Macla Nappe, Audia Nappe, Tarcau Nappe, Vrancea Nappe and Subcarp Subcarpathian Nappe, senso Sandulescu [ 1], 1984). The Moldavian tectogenesis (intra Volhini an) concludes the Carpathian structogenesis and edification of the major morphostructural lines of the Carpathian contact with the eastern foreland. Between the Suceava and Mod ova valleys, the transition from the mountainous relief (Obcina Mare) to the pla teau is made through the piedmont hills formed on the sub sub-Carpathian molasse or the Volhinian platform couverture deposits, accumulated on the wedgewedge-top of the Carpathian orogenic prism. |
