On the early Flandrian stratigraphy and vegetational history of the North Satakunta area, western Finland

The stratigraphical sequence of two till beds with varved clay between them has been described from the North Satakunta area. The position of this sequence in geochronology has been compared with the retreat process of the ice in southern Finland. It has been suggested that the sequence is early Fla...

description The stratigraphical sequence of two till beds with varved clay between them has been described from the North Satakunta area. The position of this sequence in geochronology has been compared with the retreat process of the ice in southern Finland. It has been suggested that the sequence is early Flandrian in age and it seems to show a corresponding climatic rhythm as can be seen from the pollen stratigraphy of north-western Europe (Ostfriesland, Germany) during the Pre-Boreal period. The early Flandrian vegetational history of the North Satakunta area shows the open plant communities on the emerged dry land of the archipelago character. During the regression of the Yoldia Sea and after pollen zone transition IV/V the forest expanded rapidly in the area studied.
