Dinoflagellate cyst stratigraphy of the upper cretaceous of western Belgium

A detailed micropalaeontological analysis with dinoflagellate cysts of the Cretaceous sections intercepted by five wells in western Belgium allows a biostratigraphical correlation and a chronostratigraphical interpretation of the sediments concerned. The transgression of the Cretaceous sediments on the southern part of the Palaeozoic Brabant Massif appears to be strongly diachronous. In the Nieuwkerke and Oostduinkerke wells, situated south of the present day topographic crest of the Brabant Massif (Nieuwpoort-Oudenaarde), the transgression is dated as Late or latest Cenomanian and close to th...
