Problems of selection and correlation of stratotype sections of the Neocomian in West Siberia in the context of clinoform structure

This paper discusses the problems of selection of stratotype sections and correlation of marker beds in the Neocomian productive complex of West Siberia in the context of its clinoform structure. In this paper we present a conceptual sequence stratigraphic model and a correlation chart for beds from different lithofacies regions of the Berriasian-Lower Aptian deposits of West Siberia.
