Late Weichselian and Flandrian biostratigraphy and chronology from Hochstetter Forland, Northeast Greenland
Two lakes on Hochstetter Forland have been analysed with respect to lithostratigraphy and pollen and algae stratigraphy. The sediments have been radiocarbon dated and these dates show that Hochstetter Forland was not covered by the Inland Ice during the Late Weichselian. The early Flandrian stratigr...

Two lakes on Hochstetter Forland have been analysed with respect to lithostratigraphy and pollen and algae stratigraphy. The sediments have been radiocarbon dated and these dates show that Hochstetter Forland was not covered by the Inland Ice during the Late Weichselian. The early Flandrian stratigraphic sequences of the two lakes are interrupted by barren interzones, dated at 10 100 - 8100 B. P. and 10 100 - 9200 B. P., which are partly correlated to an ice-advance. No evidence for an earlier ice-advance during the Late Weichselian has been found. Apart from the abundance of pollen grains indicating pioneer vegetation, Artemisia pollen grains are found in high quantities in the Late Weichselian, although it is today not found within the area.
