sediments. The formation of periglacial phenomena is also dependent on the geomorphologic, lithologic, and hydrologic conditions. The Pleniglacial sequence is subdivided into early and late Pleniglacial stades, both characterized by permafrost conditions
, interrupted by a middle Pleniglacial interstadial complex with clearly milder conditions.
Outline of river adjustments in small river basins in Belgium and the Netherlands since the Upper Pleniglacial in Lake, mire and river environments during the last 15.000 years.
Small river-basins in lowland areas of Belgium and The Netherlands show four episodic river adjustments since the Upper Pleniglacial, dated at the end of the Pleniglacial/early Late Glacial and the Late Dryas, Boreal, and Subboreal/Subatlantic
A palaeoclimatic interpretation of frost-wedge casts and aeolian sand deposits in the lowlands between Rhine and Vistula in the Upper Pleniglacial and Late Glacial
is shown by generalised transects from west to east, given in five time-sections from the Upper Pleniglacial to the end of the Pleistocene. The sedimentological analyses give evidence of the sedimentation processes and changing climatic conditions
The middle Pleniglacial succession consists of humic loam layers which are interpreted as thaw lake deposits. The upper Pleniglacial coarse fluvial sand is correlated with the lower part of the Beuningen Gravel Bed. Late Glacial aeolian and slope
deposits cover these Pleniglacial deposits and relief. The tentative stratigraphic interpretation of these valley sediments is based on superposition and palynological data of pollen-bearing organic levels. However, the radiocarbon dates from the thaw lake
Changing fluvial style of periglacial lowland rivers during the Weichselian Pleniglacial in the eastern Netherlands in Periglacial processes and landforms.
Permafrost existed as early as the Early Pleistocene. An attempt has been made to calculate its thickness at the basis of computer technique in the Upper Pleniglacial. - (MS)
There are two segments of the flood plain near Pleszów site. The older was formed by the braided river during the Younger Pleniglacial and the younger by the early Atlantic paleomeander. At the Łęg B site is the filling of deep incised Allerod
meanders. It allows us to consider the paleomeander in Nowa Huta as preserved in morphology Allerod channel. The process of rapid dissection of the Younger Pleniglacial alluvial plain most likely started immediately after the maximum of the last glaciation
from Central Saxony. The AA. obtained information about a climatic shift from more humid to more arid conditions during the late Pleniglacial, due to changes in the landscape dynamics of the study area : At ca. 30 ka, braided river floodplain
). Based on empirical investigations and comparative paleoclimatic data the authors assume a widespread and contiguous permafrost for the carpathian Basin during the upper Pleniglacial period. - (ZK)
After the maximum of the last glaciation three main periods of aeolian activity may be distinguished : at the end of the Late Pleniglacial, in the middle of the Late Glacial (Older Dryas) and at the very end of the Late Glacial (latest part
The valley of the river Mark (Belgium) is filled with deposits of fluvial and aeolian origin accumulated during the Pleniglacial or the beginning of the Late Glacial, not later than 12.000 yr BP. The aim of the investigations was to determine those
