| Abstract: Twelve time
interval maps were constructed which depict the plate tectonic configuration,
paleogeography and general lithofacies. The aim of this paper is to provide
the geodynamic evolution and position of the major tectonic elements of
the area within the global framework. The Hercynian orogeny was concluded with the collision of Gondwana and Laurussia, whereas the Tethys Ocean formed the embayment between the Eurasian and Gondwanian branches of Pangea. The Mesozoic rifting events resulted in the origin of the oceanic type basins like Meliata and Pieniny along the northern margin of the Tethys. Separation of Eurasia from Gondwana resulted in the formation of the Alboran-Ligurian-Pieniny Ocean as a part of the Pangean breakup tectonic system. During the Late Jurassic-Early Cretaceous time, the Outer Carpathian rift had developed. Latest Cretaceous-earliest Paleocene was the time of the closure of the Pieniny Ocean. Adria-Alcapa terranes continued their northward movement during Eocene-Early Miocene time. Their oblique collision with the North European plate led to the development of the accretionary wedge of Outer Carpathians and foreland basin. The formation of the West Carpathian thrusts was completed by the Miocene time. The thrust front was still progressing eastwards in the Eastern Carpathians. |
Abstrakt: Dla obszaru wokółkarpackiego skonstruowano 12 map
przedstawiających konfigurację płyt litosferycznych, paleogeografię
i uproszczony rozkład litofacji w okresie od późnego karbonu po neogen.
Przedstawiono ewolucję geodynamiczną tego rejonu na tle ruchu płyt i
pozycji głównych elementów tektonicznych w globalnym układzie odniesienia. |
