Abstract

The chronological analyses, earlier corings and the lithostratigraphical analogies to the sediments indicate that they had been deposited continuously from the Middle Würm to the close of the Holocene. The pollen profile is dominated by non-arboreal pollen, even during the Holocene. In this sense, this pollen profile is unique and it can only be compared to other pollen sequences from the Hortobágy because deciduous arboreal pollen did not become dominant in any one pollen zone. This pollen composition provides evidence that alkalisation was continuous from the Middle Würm to the close of the Holocene. The alkalik species formed a vegetation intermixed with taiga during the Pleistocene, resembling the one which can be observed in southern Siberia, in the Altai foreland, where a steppe belt with alkalik elements was intermixed with deciduous woodland and taiga elements, but breaking up into a mosaic of taiga interspersed with grass steppe and deciduous woodland in consequence of extremely diverse local orographic, hydrological and hydrographical conditions. A landscape showing a similar mosaic patterning with a dominance of steppe elements developed in the Hortobágy region at the close of the Pleistocene and survived throughout the Holocene.
