The dependence of rheological properties fanerozoj rocks from one-directional tectonic forces and comprehensive pressure are investigated using the experimental data. The stress and strain fields are obtained based on the solution of two-dimensional problems of thermo-elasto-plasticity. These fields prove the dependence of comprehensive pressure and plasticity of the rocks from the levels of one-directional tectonic forces. The elaborated software gives the possibility to predict the main features of the paleotectonic stress fields in the crust with different boundary conditions, medium parameters and thermal fields.
