The process of formation of sedimentary basins is considered as a result of long term vertical movements and is partitioned into two stages. The first one is essentially the formation of a depression in which water and sediments collect (the time scale of this process is of the order of 107 yr). The second stage is the process of isostatic adjustment (time scale of ~108 yr). A numerical model of the initial subsidence of sedimentary basins is presented. This model is realized by the solution of the coupled two-dimensional time dependent equations of viscous motion and of heat transport in the lithosphere-asthenosphere system characterized by nonlinear rheological features. As a result of the present calculations, the subsidence of the Earth’s surface or the formation of a depression can be attributed to the mechanism of a secondary convection induced mechanically by subducting litho-spheric plates. Besides the formation of the depressions themselves, the present approach makes it possible to treat a number of accompanying processes, such as the uplift of hot or more dense material, the general frictional heating of the area of interest from below, e. t. c. As an illustration, the present approach is applied to the formation of the Pannonian basin.
