The strain-stress state modelling of the sedimentary complex in collision zone and dynamic conditions of early thrusts formation in the Ukrainian Carpathians
Series of the finite-element 2D-models of thrusts in the flysh basin on the base of elastoplasticity equations for piecewise-homogeneous medium are proposed. Using computer modelling the formation mechanism of thrusting in the Ukrainian Carpathians during Early Cretaceous is improved. Within the framework of the complex analysis the fields of calculated stresses and strains of the sedimentary rocks in the collision zone are studied. The place of first thrusts with general Carpathian orientation, the role of tectonic displacements and paleo-basin basement morphology are determined.
