Abstract: The article deals with the cyclic structure of Jurassic deposits of the North of Western Siberia. To substantiate the regional cyclites correlation method was used, which implements the principle of chronostratigraphic section intervals tracking, using an approach based on a combination of the correlation method of frame, cyclites and characteristic intervals of pore pressure gradients curves. Previously, from the graphs of the tectonic subsidence structures, the scheme of cyclicity of Jurassic tectonosedimentary complexes at the studied shelf of the Kara Sea is refined
