LATE CRETACEOUS THROUGH PALEOGENE EVOLUTION OF MAGURA BASIN

Year, pages: 1992, 333 - 338

The evolution of the Magura Basin from the Middle Cretaceous. to the Early Oligocene is outlined. The Magura Nappe is the largest tectonic unit of the Western Carpathians, linked with the Rheno-Danubian flysch of the Eastern Alps. During tectonic movements the Magura Nappe was completely uprooted from its substratum along ductile Upper Cretaceous rocks. Older deposits are known only from that part of the basin which was incorporated into the Pieniny Klippen Belt. In the sedimentary evolution of the Magura Basin three different periods can be distinguished: the Middle Jurassic–Albian long-lasting (96 MY), extensional period of the pelagic deposition, the Cenomanian–Campanian (23 MY) period of hemipelagic deposition, and the Maastrichtian–Early Oligocene (40 MY) mainly compressional period of turbiditic deposition. During the Eocene gradual shifting of coarse-clastic deposition from the south to the north took place. It was connected with development of two large submarine fans, partially superimposed one upon another. The progradation of these fans can.be related to the shortening of the Magura Basin and to the development of accretionary prism.
