Our study was focused on narrow linear zones that penetrate to different depths the crust and have complex infrastructure. Rocks in such zones are more intensively tectonically altered in comparison with the background. ‘Flower structures’ and

Thrust faulting has been studied within the framework of a tectonic wedge model. A variant of the model was proposed which accounts for changing friction between the wedge bottom and a rigid foundation during irreversible deformation. Some specific d

The paper presents results of numerical calculation of displacement of a geomedium block along the inclined plain in the presence of a round friction spot. Modeling reveals differences in processes for the elastic and elastoplastic media. In the elas

Problems of the description of deformation and fracture of rocks are under discussion. The dependence of their properties on the stress state, rheology, and accumulated irreversible deformation is studied. A mathematical model describing the geomediu

The nonlinear rock behavior effects observed in loading diagrams are analyzed which are usually ignored in conventional models of elastoplastic media. The initial deformation stage and unloading of rock samples are considered. The nonlinear behavior

The results of numerical modelling of deformation of the Earth’s crust along the Tarim–Altai profile caused by the force of gravity and lateral compression using the approximate two-dimensional model of the elastoplastic transition are presented.

The effect of sphericity on the stress-strain state of the Earth’s crust was evaluated by adapting a numerical algorithm for the solution of a 2D boundary value problem using a calculation scheme constructed for the Cartesian coordinate system. The
