Dead-ice features at the maximum extent of the last glaciation in northeastern Poland
Last ice sheet dynamics and deglaciation in the North European Plain
The maximum extent zone of thhe Vistulian Glaciation in northeastern Poland is composed of a complex pattern with alternating dead and active ice features. The former include tripartite fabric of till in morainic plateaux as well as depressions
of varying size, often with numerous secondary forms. Active ice zones represent probable ice streams within the ice sheet, reflected by outwash plains and previous subglacial channels. Different sediments in each zone suggest a coincidence of dead-ice
features with cold ice whereas ice streams corresponded presumably with temperate ice that produced intensive meltwater outflow.
Ice margins and deglaciation in the Berlin area between Brandenburg and Frankfurt end moraines. A review
Last ice sheet dynamics and deglaciation in the North European Plain
The views of different AA. concerning the reconstruction of the ice marginal positions of the maximum advance and the retreating inland-ice are given. Typical features are outwash plains, meltwater channels as well as kame-like meltwater deposits
instead of depositional or push end-moraines. The landscape development in relation to the melting of dead-ice is discussed as Laach tephra has been found in kettle holes and lake deposits undisturbed.
Dynamics of the last ice sheet within the territory of Belarus
Last ice sheet dynamics and deglaciation in the North European Plain
The combination of geomorphological and geological methods made it possible to reconstruct the pattern of degradation of the last (Poozerje) ice sheet within the territory of Belarus. The phase and oscillatory chains of terminal moraines were
distinguished within the known stadial complexes of marginal glacial formations. It was shown that the structure of stadial ice sheets was rather complex and included lobes and tongues of various sizes and configuration, which were largely independent
The problem of the Warsaw ice-dammed lake drainage through the Warsaw-Berlin Pradolina at the last ice-sheet maximum
Last ice sheet dynamics and deglaciation in the North European Plain
The AA. consider the possibility of the drainage of excess water from the Warsaw ice-dammed lake through the Warsaw-Berlin Pradolina. The lake was a result of a dam formed at the maximum of the Vistulian Glaciation. First, the question
of the relation between the Warsaw-Berlin Pradolina and the Warsaw ice-dammed lake is examined on the basis of various researchers' views on the origin and age of the levels and terraces, as well as the deposits of the Warsaw Basin.
Last ice sheet dynamics and deglaciation in the North European Plain
The eastern Baltic was among the regions where the theory of continental glaciation was elaborated. However, researchers still disagree as to the extent and thickness of the dead-ice fields. In the course of deglaciation active, passive and dead ice
conditions probably underwent a gradual change depending upon the stade of deglaciation (Dani-, Goti-, and Finiglacial). Flow tills and collpses of ice cavities were common in dead-ice areas, which is why organic layers with different ages often occur
Geomorphological, sedimentological and structural records of ice front dynamics during the Upper Plenivistulian: an example from the southeastern part of the Chelmno-Dobrzyń lakeland
Last ice sheet dynamics and deglaciation in the North European Plain
The dynamics of the last Scandinavian ice sheet in the territory of Poland displayed considerable variety. A 300 km2 study area near the maximum extent of the ice sheet was chosen to consider the landforms, the deposits and their internal structure
which developed during the positive, negative and steady-state ice balances. The main factors affecting the dynamics of the ice sheet at the time of its maximum extent and during the Kuyavian Subphase are also discussed.
A new approach to Late Weichselian ice sheet dynamics in western Poland
Last ice sheet dynamics and deglaciation in the North European Plain
The marginal zone of the Poznań Phase of Late Weichselian glaciation in western Poland has been deposited in steady-state conditions of the ice-sheet margin. Recent investigations suggest that two Late Weichselian tills occur at this marginal zone
, suggesting a re-advance. Petrological data suggest also a change of ice flow direction from north-south during the major advance to northeast-southwest during the readvance. Thus now, almost all marginal zones of the Late Weichselian glaciation in western
Poland formed during the general deglaciation have evidence of ice-sheet re-advances.

the following features of the marginal zone: ablation end moraines, marginal edges of outwash plains, ridges and depressions left by the melting of the cores of ice-cored moraines, collar ridges of melt-out lake basins, and marginal kames and kame-and-kettle
zones. It is assumed that these specific features were influenced by the changing ice mass balance and by the substratum morphology.
Last ice sheet dynamics and deglaciation in the North European Plain
This paper concentrates on the Late Weichselian deglaciation rates and the different mechanisms that might have caused the rather rapid wastage of the Danish sector of the ice sheet. The analysis is carried out using the improved possibility
of obtaining numeric 3D-reconstructions on the surface form of former ice sheets, given their former margins and the physical character of the substratum. Also results obtained from insolation calculations as well as empirical knowledge on ablation rates from

A key problem when reconstructing the recession of the Weichselian ice sheet has been the difficulty of producing an acceptable glaciodynamic model for the southern Baltic Sea area. A recently started Polish-Swedish project aims at reconstructing

of the beetles are reconstructed by comparison with their present habitats. Close to the margin of the ice shield the Coleoptera fauna proved to be more diverse, even including species of the present-day northern taiga area, than in the more humid periglacial
