A palynofacies study of past fluvio-deltaic and shelf environments, the OligOcene-Miocene succession, North Sea Basin: A reference data set for similar Cenozoic systems

摘要

Correct interpretations of depositional environments are fundamental for evaluating the geological history of a sedimentary basin. Palynofacies analyses are a valuable supplement to sedimentological and seismic studies. In order to develop a palynofacies reference dataset for fluvio-deltaic and shelfal successions, a study of the assemblages of sedimentary organic particles from seven different well-defined depositional environments within the uppermost Oligocene - lower Miocene succession onshore Denmark (eastern North Sea Basin) has been performed. The study deals with the following environments; floodplain, lagoon, washover-fan flat, prodelta, shoreface, offshore transition and shelf.
