A pollendiagram from the Weichselian deposits near Apeldoorn, the Netherlands

Abstract

Pollen analysis of a 20 m long core of peat, sand and silt deposits near Apeldoorn, the Netherlands shows that these sediments were laid down in the Late Eemian, the Early Weichselian and the Middle Weichselian. Only the most upper Eemian is present- In the Early Weichselian one zone with interstadial character and represented by a peat layer is particularly well developped, showing succesive maxima in the pollen values of Alnus, Picea and Pinus. Pollen of Betula however remains dominant. The Middle Weichselian is strongly glacial in character. It includes an oscillation with Salix, Potamogeton, Pediastrum and SeIaginella selaginoïdes pointing to more favourable conditions.
