Abstract


Remarks on the deposits with Pliocene flora in the east part of Nowy Targ Basin and at Krościenko on the Dunajec river (Western Carpathians)

The article concerns the genesis of sediments with the Pliocene flora at Krościenko on the Dunajec, Mizerna near Czorsztyn and Huba (Szafer, 194b— 1947, 1954), and also in the profile of a bore-hole at Frydman (Niedzielski, 1971). The author concludes that the sediments with the Pliocene flora, may be except the flora from Hube which was considered to be of the Upper Miocene age (Oszast, 1973), originally exceeded their present sites by at least 100 m; from there they were redeposited to the foot of slopes of the Gorce mountain range in the Pleistocene. In this respect the discussed deposits would be relict remnants of a continuous cover which rested on the flora-bearing Miocene sediments filling the Nowy Targ — Orawa Depression. The damage of the Neogenę cover in the described part of the Depression was caused by Pleistocene oscillations of climate, periodically intensifying the gravitational land slides and solifluction processes accompanied by increased activity of rivers, especially the Dunajec and the Białka. Apart from it, tectonic movements were of great importance. They caused the formation of tectonic depressions along the southern slopes of the Gorce range.
