Objective. The objective of this study is to analyze the influence of the Pokuttia deep fault on tectonics and the oil- and gas-bearing of the south-eastern part of the Ukrainian Carpathians. Methodology. It is contained in the detailed complex analysis of the geological-geophysical data on the given area.
The model of the geologic evolution of the Carpathians both in terms of the terrane analysis and in the light of the new data of the geologic mapping are represented.
The tectonic units of the Carpathians are considered in terms of the terrain analysis. Carpathathian orogen is build up of three main elements: microcontinental terrains, sutures and flysch-molasse accretionary prism. There are two main terrains: a northern ALCAPA and a southern Tisza-Dacia. Sutures (Fore-Marmarosh suture, Pieniny Klippen Belt and others), marking the ancient oceanic basins, bound these terrains. The Flysch Carpathians are regarded as the Cretaceous-Neogene accretionary prism.
