In the article the first results of researches of joints and slickensides from outcroppings in the valley of the Sukil River are given. In 37 points of the flysh deposits of thrusts: Orivska, Skolivska and Parashka about 1100 intentions of joints and 90 intentions of slickensides are executed in the different deposits strata: from the Upper Cretaceous to Oligocene formations. By the complex (method of structural paragenesis and kinematics one) analysis of these mesostructures, with the use of the modern computer providing (StereoNett, Win-Tensor and other) the reconstruction of main parameters was carried out. Deformation regimes and orientations of main axes of the old and young stress fields which occur in Paleogene-Neogene time to and during and after fold formation in this area of Ukrainian Carpathians was specified.
