Opis:
The investigation area is situated in the north part of Mazurian Lakeland in NE from Węgorzewo in the borderland between Poland and Russia. It was covered with the ice sheet during the upper stage of the Vistulian Glaciation. During the recession of the maximum range of the ice-sheet (Pomeranian Phases) the 6 ice-sheet retreated were left. Skaliska Basin this is end depression, between two end moraine zones. The glaciolacustrine and lacustrine sediments was recorded late glacial and postglacial history. The results of the multidisciplinary investigations including cartographical, sedymentological methods indicate that in the ice-dammed lake in Skaliska Basin was existed in front of the ice. The outflow from Skaliska ice-dammed was connected with the ice sheet retreat (behind the Pregoła Valley) and development of the new erosion base level (like Pregoła Valley).

Opis:
The most representative and long Late Pleistocene pollen sequences covering the late glacial of the penultimate glaciation (Warta/Pripiat), the last interglacial (Eemian/Muravian) and the early glacial of the Last Glaciation (Vistulian/Poozerie) from the territory of Poland and Belarus have been correlated. The resemblance ofpollen spectra in these pollen sequences and a parallel succession of Regional Pollen Assemblage Zones in the considered time intervals suggest that the natural environment of Poland and Belarus underwent synchronous changes under unidirectional climatic transformations. Qualitative and quantitative features of the Regional Pollen Assemblage Zones show similarities and differences in vegetation and climate changes in the study area. A comparison of the pollen spectra from Poland and Belarus suggests that both territories were affected by a similar climate particularly during the cold intervals. Some differences between the compositions of the pollen spectra were noticed as concerns the interglacial period. For instance, Abies and Taxus pollen as well as significantly high percentages of Calluna vulgaris pollen in NE Poland towards the end of the period are present only in the Polish sections. This may suggest a more Atlantic type of the climate during the Last Interglacial in Poland than in Belarus.

Opis:
During the maximum of the last glaciation the Vistula ice lobe was one of the key morphological elements at southern margin of the Scandinavian Ice Sheet in north-central Poland. The area of the Vistula ice lobe experienced two ice sheet advances of varied extent, the earlier one during the Leszno Phase and the younger one in the Poznań Phase. According to the authors, the limit of the Leszno Phase within the study area was much smaller than hitherto accepted and its age is estimated at about 20.5 ka BP. Significant ice sheet retreat was followed by an ice readvance during the Poznań Phase, overriding the extent of the Leszno Phase. The Poznań readvance reached the maximum limit in the Vistula ice lobe area about 18.5 ka BP. It is assumed that the rapid ice sheet transgression during the Poznań Phase (on average 400 m/a) and origin of the Vistula lobe were probably connected with activity of the palaeo-ice stream.

Opis:
The paper presents the results of geomorphological studies and pollen analysis performed for alluvial deposits at 2 sites situated in the Wisłok River valley. The deposits consist of thin layers of organic muds filling palaeochannels or thermo-karst lakes of the Wisłok River, dated at the Interpleniglacial (Grudziądz Interstadial) of the Vistulian Glaciation. These deposits build the lower part of a sand terrace, 8-12 m high, and outliers of this terrace buried by overbank alluvial sediments within a floodplain. The samples for pollen analysis were taken from a natural undercut in the Wisłok River channel and from a sand pit dug to a greater depth. The pollen diagrams prove the existence of trees (forest-steppe) including primarily Pinus sylvestris, Betula t. alba, Pinus cembra and Larix. The diagrams do not show a clear tendency of a plant succession and thus of any distinct climate changes. The sedimentation took place under cool, boreal climate conditions. The occurrence of several layers of organic and sand deposits in the sections does not reflect rhythmic warm/cold climatic oscillations documented in the Interpleniglacial alluvial sequences in Western European rivers, but is a result of vertical channel fluctuations and facies changes.

Opis:
The article presents the results of geological and geomorphological research concerning load-cast structures outcropping in the alluvial terrace sediments of theWisłok River in the Fore-Carpathian Erosional Valley. Given the large dimensions of these structures, reaching 1.5 m in some places, as well as their strong accumulation and diversity (i.e. drop-like and pocket-like structures), the authors attempted to establish the environmental factors that had determined the development of the structures in periglacial deposits of the Weichselian Glaciation. The structures were analysed in two accessible outcrops where sediments are represented by flood rhythmite and organic deposits, overlain by channel sands. Sandy load-cast structures occur in flood rhythmite and loamy deposits. The formation of load-cast structures probably started due to earthquakes in the Upper Pleniglacial period. The various shapes of load-cast structures were constrained by the various physical properties of the sediments and the escape of water during the deformation process.

Opis:
The Orłowo Cliff is built of glacial and fluvioglacial deposits, Middle Polish Glaciations (possibly Odranian and Warthanian) and Vistulian Glaciation. Deposits are heavily deformed glaciotectonically. In the northern part of the cliff, Miocene sediments are exposed. It is possible, that the Miocene sediments were dislo-cated from their primary position. There were observed overthrusts and intermingling with Pleistocene material in the lower part of the exposure. The Orłowo Headland is built of glacial tills. It is probably a part of fold, similar in pattern to the structure of overthrust folds present in silty-sandy-grained deposits in the southern part of the cliff. Apart from folds and overthrusts there are many faults and the boudinage. Structural analysis of glaciotectonic deformations in conjunction with origin of deposits and statigraphic research enabled the recognition of several stages of development of deformations. Two local directions of glaciotectonic transport were marked clearly: from the north-east, which was connected with glacier invasion in the OEwiecie Stadial of the Vistulian Glaciation, and direction from north-west (north north-west), related to the Main Stadial of the Vistulian Glaciation.
