The paper reports on numerical modeling of the formation of a fault structure in a geomedium layer in stick-slip displacement of the base. Consideration is given to structural peculiarities of strain localization zones at different stages of evolution: from nucleation to formation of a main fault. It is found that the localization zones from the rupture in the base develop as pairs of surfaces similar to oyster valves. It is shown that different types of flower structures can be formed depending on the material properties and layer thickness. In one type of flower structures, the main surfaces are the surfaces R of Riedel bands; in the other, the surfaces oriented at an angle of ~40° about the shear axis in the horizontal plane. A unified main fault is formed from above, once the inclined localization zones reach the surface.
