Stratigraphy and paleogeography of Berriasian–Lower Aptian deposits of West Siberia in connection with the clinoform structure of the section

The evolution of views of the stratigraphy of Berriasian–Lower Aptian deposits of West Siberia is described. In connection with a clinoform model of the section structure, suggestions are made for its stratification; according to new recommendations to the stratigraphic scheme, paleogeographic reconstructions were carried out for the four stratigraphic units identified in the Berriasian–Early Aptian play.
