The architecture of the sedimentary cover of the West Siberian plate is analyzed within the limits of a kinematic model implying cyclicity of deposition controlled by tectonic subsidence and uplift. The model accounts for the formation mechanism of large- and smaller-scale lithostratigraphic units (formations, members, sand beds). The vertical distribution of sedimentary units and markers in the section is controlled by the dominant 18 myr periodicity of tectonism. The paleogeography of the region is reconstructed for different periods in the context of an oscillatory process. Correlation of the theoretical lithostratigraphic units with the actual sedimentary section shows that the proposed kinematic model may provide a basis for detailed stratigraphic division of the platform cover of the West Siberian plate.
