چکیده انگلیسی
The research well “Messel 2001” penetrated the sediments of the Middle Eocene maar lake at Messel (near Darmstadt, Hesse, Germany) completely. The core includes 140Â m of lacustrine oil-shale overlying 90Â m of clastic lake sediments which are assigned to the Middle and Lower Messel Formation, respectively. Numerical techniques like TWINSPAN and correspondence analysis have been applied to a high-resolution palynological study. The Lower Messel Formation is equivalent to the Initial Lake Phase and shows a clear succession of pollen and spore associations representing a succession of plant communities colonizing and invading the area which was previously devastated by the eruption(s). On the basis of the TWINSPAN, an Early and a Late Initial Lake Phase may be distinguished. But, throughout the Initial Lake Phase, the regional climax vegetation did not change substantially and had re-occupied the area finally at a time roughly representing the boundary between the Lower and the Middle Messel Formation.
