Relief and geological structure of Vyzhnytskyi and Cheremoskyi national natural parks (Ukrainian Carpathians)

Authors

Abstract

The analysis of morphosculpture of NNPs shows the types characteresed the Carpathian Flysch and Сrystalline Carpathians. Mountain ranges and ridges such as Bukovyna med-mountains, Pneve-Yarovytsi and part of Chyvchyn mountains are characterized by an asymmetrical structure – steep northeastern slopes and declivous southwestern slopes. The relic morphosculpture is represented by: 1) fragments of denudation surfaces of different ages such as Polonynska and Pidpolonynska within Cheremoskyi NNP as well as Karmaturska (analogue of Pidbeskid) within Vyzhnytskyi NNP; 2) extra glacial landforms within Cheremoskyi NPP; 3) areas of ancient longitudinal valleys. The inherited morphosculpture is represented by river valleys with a complex of terraces of different ages. 

Modern morphodynamic processes represent a height (tier) differentiation. The highest tier of apical surfaces in the subalpine zone of Cheremoskyi NNP is characterized by processes of slow displacement of debris and manifestations of gravitational, avalanche and nival processes. In the tiers of strongly dissected mеd-mountain and low-mountain relief of NNPs, the processes of planar erosion, deflux, and linear erosion play an important role in the modelling of the relief. The lower tier of the terraced and non-terraced bottoms of the valleys are associated with the processes of leaching and erosion.
