Lithological and stratigraphic criteria of geohazards within the Dniester river basin

Abstract

Summary This study is devoted to key lithological and stratigraphic criteria influencing the development of geological hazards in the Dniester river basin. The most important geological outcrops, which are monuments of nature and geology located in the Chernivtsi region on the right bank of the Dniester River, have not been previously studied in terms of stratigraphy. The studied outcrops of Cretaceous and Neogene sediments need to be monitored and preserved. The audit of local stratigraphic subdivisions was carried out and the paleontological characteristics of stratigraphic schemes of the north-western outskirts of the Ukrainian Shield were supplemented. Zonal schemes based on dinocysts and spore-pollen complexes were constructed. The Cenomanian, Turonian (Cretaceous) and Tortonian-Sarmatian (Neogene) deposits, which are exposed on the right bank of the Dniester, are correlated with the same-age deposits of the left bank and adjacent territories.
