Geological position and pollen analysis of Eemian Interglacial sediments of Warsaw-Wawrzyszew.

Summary: Organogenic sediments filling the basin of a fossil reservoir in the through-like depression in the surface clay of the Warta Stadial are preserved in the north-western part of the Warsaw-Wawrzyszew. Distinct traces of active periglacial processes and erosional dissections are well marked in the top part of these sediments. The sediments are overlain by sands. Palynological results concerning five profiles of lacustrine and post-lacustrine sediments of Warsaw-Wawrzyszew permit us to distinguish and characterized 22 local zones. An analysis of the floristic elements and the features of the succession reflect of the environmental changes in the Late Glacial of the Middle Polish Glaciation and represent the full developmental cycle of interglacial vegetation and the beginning of the Early Vistulian.
