A multi-disciplinary study of fluvial, paralic and shallow-marine depositional systems of the Cenomanian age of the Bohemian Cretaceous Basin (BCB), Czech Republic combines methods of sequence stratigraphic analysis based on well-log, core and outcrop data, with paleontological and structural analysis, to obtain a detailed picture of evolution of depositional systems and their geometries in space and time. The geometries of Cenomanian strata deposited during the initial phase of basin evolution provide a direct link to the kinematic behaviour of basement structures - especially the Saxothuringian/Tepla-Barrandian suture and the Elbe Fault Zone during the Cretaceous reactivations - and the possible involvement of eustatic fluctuations of variousfrequencies. The research will focus of assessing the relative roles of tectonics and eustatic sea-level change in creating and filling accommodation in an intracontinental basin. This study will also contribute to better understanding of the mechanisms
