Die pollenanalytische Gliederung des Postglazials im nordwestdeutschen Flachland

Heinz Schmitz
The subdivision of the Postglacial in the flat country of northwestern Germany is based on the pollenanalytical zonation, easily recognizable, of the development of the forest. These zones however are synchronous in a widely taken sense only. On the other hand for comparison of periods it is possible to determine some horizons indicating variations in the forest caused by climatic changes. The immigration of trees cannot serve as a synchronous line, even not, if the...
