Opis:
An overview of the existing opinions combined with new geomorphological, geological, palaeopedological and TL data allow a new look at the number, age and ranges of the three Middle Polish (Saalian, Dnieperian) Glaciations in central-eastern Poland. During the first of these glaciations (Liviecian), correlated with the 10 oxygen isotope stage in deep-marine deposits (400–360 ka), the Scandinavian ice-sheet advanced in form of a rather narrow lobe, reaching only several tens of kilometres south of Warsaw. During the second glaciation (Krznanian), correlated with the 8 oxygen isotope stage (330–320 ka), it advanced in form of a wider lobe down to the northern margin of the Małopolska and Lublin uplands. In turn, during the third glaciation (Odranian), correlated with the 6 oxygen isotope stage (210–130 ka), the range of the Scandinavian ice-sheet was the largest. It stopped at the elevations of the Quaternary basement in the northern and western part of the Małopolska and Lublin uplands, reaching 330–280 m above sea level. In the study area the discussed glaciations are separated by two interglacials (Zbójnian, Lublinian = Lubavian), correlated with the Reinsdorf and Schöningen interglacials in Germany and Landos and Le Bouchet interglacials in France. The analysed data indicate that within the Odranian Glaciation, its maximum (Kamienna = Drenthe) and postmaximum stadials (Warta = Warthe), as well as two younger recessive stadials (Wkra, Mławka) should be distinguished. Due to the rather wide eastward distribution of the Scandinavian ice-sheets during the two younger glaciations, an attempt has been made to correlate them with the two Dnieperian glaciations in the Ukraine.

Opis:
Tills in fluvioglacial cone of Sucha Woda Valley near Toporowa Cyrhla and Niżnia Palenica Pańszczykowa were recognized during mapping Tatra Mountains in scale 1 : 10 000. Tills with big boulders occur outside maximum range of Würm Glaciation end moraines and probably were accumulated by glacier of Riss Glaciation. Grain size composition, petrographical content (grains 5–10 mm) and compositions of heavy minerals (grains 0.1–0.25 mm) were investigated in tills. Dusty and clay fraction prevails (50–70%) above sandy and gravel fraction in these sediments. Gravel of granite without sandstone predominates in samples from Toporowa Cyrhla and gravels of sandstone with granite prevail in deposits of Niżnia Palenica Pańszczykowa. Granite in tills deposits occur in upper part of Sucha Woda Valley near Hala Gąsienicowa. Sandstone occur in middle and lower part of valley. Different petrographical content of samples from Toporowa Cyrhla and Niżnia Palenica Pańszczykowa could indicate various glaciers accumulated tills or various age of investigated sediments. Non-resistant minerals and magnetite prevail among heavy minerals. These investigations suggest glacial origin of these deposits and delimit bigger range of glacial tills by this day.

Opis:
Based on geological and paleobotanic data, the oldest valley system of the Niemen River is linked in the study area with a river located southward of Grodno, within a parallel valley from the Alexandrian (Mazovian) Interglacial. The foundations of the present-day, almost meridian course of the Niemen River valley, are connected with a system of post-glacial lakes from the Sozhian (Wartanian) Stadial of the Pripethian (Odranian) Glaciation, later filled with organic deposits of the Muravian (Eemian) Interglacial. Analysis of six sites with these deposits (Pyszki, Rumlówka, Poniemuń, Żukiewicze, Bohatyrowicze and Kniażewodce) indicates that they represent three lakes located at different altitudes. During the maximal range of the Dvinian (Main) Stadial of the Poozerian (Vistulian) Glaciation, the lakes were beyond the range of the ice-sheet. At this time, the highest located deposits of the Poniemuń-Żukiewicze lake were covered by sander sediments, whereas the Bohatyrowicze-Kniażewodce and Pyszki-Rumlówka lakes that were located at lower levels, were covered by fluvio-periglacial deposits and varved clays of the Skidel ice-dammed lake. Retreat of the ice-sheet of the Dvinian Stadial, resulting in outflow of water from the Skidel ice-dammed lake through the area with the two lower interglacial lakes, triggered the formation of a system of the Niemen River supra-flood terraces above them. Accumulation of the highest of these terraces (VI), during the first phase of the Skidel lake outflow, marks the beginning of the present-day Niemen River valley formation that probably began in the younger phases of the Dvinian ice-sheet retreat. Further evolution of the valley is linked with the Late Glacial formation of the middle (III-V) supra-flood terraces and with the Holocene formation of the lower (II, I) supra-flood terraces.

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.

Opis:
Erthwork during rebuilding of the S3 route in Gorzów Wielkopolski exposed sediments of a palaeolake. The thickness of the sediment complex reaches 11 m. Two gyttja layers are separated by peats and fluvial sands and muds. The sequence reflects a multiphase development of the lake. Lacustrine sediments overlie Odranian (Saalian) (MOIS 6) glaciofluvial deposits and are covered by Vistulian glacial sediments (MOIS 2). At present, the stratigraphic position of the palaeolake is dated to the Eemian (MOIS 5e), with a probable continuation of the deposition into the early Vistulian (MOIS 5d-4). Rhinoceros bones (more than 100 pieces), including a skull with 24 well-preserved teeth, were discovered in the lower part of the palaeolake sediments. The preliminary expertise report, based mainly on the teeth analysis, allows assigning the rhinoceros remains into the genus Stephanorhinus. The finding of so many pieces of the skeleton of Stephanorhinus sp. in situ is unique on the scale of European scale. Apart from the rhinoceros remains, a single metacarpal bone of fallow deer (Dama dama) was found in the site. This is the first record of extant fallow deer in the Pleistocene of Poland. The palaeolake sediments were sampled and multidisciplinary research is planned to reconstruct the history of the development of this basin. The relationship between the rhinoceros andfallow deer remains with the palaeoenvironment will make it possible to ascertain the conditions in which those animals lived at higher latitudes during the Eemian Interglacial.

Opis:
The paper presents the succession of Sanian Glaciation sediments recognized in the Swiętoszówka site, Southern part of the Silesian Foothills (Bielsko division). The following deposits were found: a unit ofgravels deposi- ted in a system offoremountain alluvialfans, a unit of silts deposited in a glaciomarginal dammed lake, and a glacial till. Glaciogenic deposits are covered with loess-like deposits. The development of the glaciomarginal zone was influ- enced mainly by the pattern ofbasement relief. In the northern part of the foothill, in the northward-oriented valleys, glacially dammed lakes were mainlyformed. During transgression, waterfrom these reservoirs was pushed in front of the ice-sheet margin towards the southern part of the low-relieffoothill. The individual lakes probably merged there into one larger glaciomarginal lake. It was characterized by low-energy conditions and deposition mainly from suspension. Sedimentation style in the lake changed over time and was dependent on the size and shape of the lake and its position in relation to the ice-sheet margin, which determined thewidth and distribution ofzones of sediment supply and the dynamics ofdepositional processes in the lake.

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 subject of the analysis was a tunnel valley, weakly outlined in the landscape, located in central Poland, between Łódź and the Pilica valley to the west of Tomaszów Mazowiecki. The Miazga and lower Wolbórka flow along this valley. It is a 45-kilometre-long landform, mostly buried, partially covered with fluvial, slope and aeolian sediments, developed on a substratum characterised by varied palaeorelief and lithology. Sediments, which fill the valley, have variable thickness (10-100 m) and a non-flattened bottom gradient line, which indicates the possibility of water flow under hydrostatic pressure in a tunnel valley. Several segments of the channel cut into the Quaternary background. The filling consists mostly of glaciofluvial shallow braided rivers with average to low flow energy. In sedimentological terms, the deposits show significant similarity to the material of glaciofluvial kames found in the Łódź region. The authors believe there is a link between the accumulation in the tunnel valley and a particular variety of areal deglaciation, which was responsible for the formation of the fairly unvarying glacial relief. In outcrops in Łaznowska Wola, including the ones located in a hill that had been previously interpreted as an esker, some intrusive diapiric structures were documented, which reached the land surface. Thesefolded and locally disjunctive disturbances provide evidence for deformational origin of the hill.

Opis:
During the Pleistocene, the Cracow-Częstochowa Upland was covered by the Scandinavian ice sheets two times, which was stated already at the beginning of the twentieth century. The Odra glaciation had probably the biggest impact on the relief of this area . The geometry of this part of the ice sheet was reconstructed on the basis of the analysis of the sub-Quaternary morphology and location of the glacial tills. The modeling of thickness of the ice sheet during the odra glaciations shows, that it was small (110–350 m) in the northern part of the analyzed area. Longitudinal profiles of the ice sheet are fairly gentle, which is typical for glaciers with high activity.

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:
The Upper Odra Lobe - the southernmost part of the Scandinavian ice sheet during the Odranian (Drenthe) glaciation - was formed in the area of the Niemodlin Plain and the western part of the Racibórz Basin. It created a complex structure consisting of several sublobes: Odra, Nysa, Ruda and Klodnica sublobes. The study focused on the basal till deposited during ice sheet advance. Ice flow directions and the general pattern ofice mass distribution in the Upper Odra Lobe were defined based on the clast fabric. The resulting distribution of ice-flow palaeodirections suggest that the Upper Odra Lobe was formed by the mass of ice moving divergently from the Opole Plain located to the north of the Racibórz Basin. Ice-flow lines coincide with the pattern of major geomorphological units. The most intensive movement of the ice took place in the depression of the central part of the Silesian Lowland. From there, in the vicinity of the Niemodlin Plain, the ice sheet moved in different directions, forming smaller sublobes in several valleys. Strong relationship between the ice flow directions and morphology confirms the idea of a smaller ice sheet extent in the Racibórz Basin and Moravian Gate. Highly concentrated flow of ice in the back-lobe area, interpreted in this study, suggests that the lobe development resulted not only from the ice sheet adapting to the basement relief, but was also conditioned by a spatially varying distribution of ice, i.e. increased ice supply to the Niemodlin Plain and the western part ofthe Racibórz Basin.

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:
A reconstruction of the last glacial maximum (LGM) ice surface geometry in the Polish High Tatra Mts. (drainage basins of Roztoka and Rybi Potok) is based on detailed field mapping of glacial trimlines. Obtained field data provide evidence of the ice surface elevation within the ice accumulation areas and in some cases they indicate direction of ice flow. The LGM ice-surface geometry is presented as a digital elevation model (DEM) which was created using geographic information system (GIS). Calculations of ice thickness and ice volume are based on DEM of present land topography. Reconstruction of the ice extent within ablation area is created using archival data. During LGM, the Roztoka glacier and the Rybi Potok glacier were a typical valley glaciers included into a huge glacial system being a dendritic glacier. According to acumulation area ratio (AAR) method, equilibrium line of these glaciers was situated at an elevation of about 1400 m a.s.l. It shows that nearly the whole area of the drainage basins of Roztoka and Rybi Potok have been an ice accumulation area supplying the Biała Woda glacier during LGM. Equilibrium line altitude (ELA) depression in relation to modern ELA (2300 m a.s.l.) was about 900 m. Assuming temeperature lapse rate of 0,6oC/100 m, a mean summer temperature in the Tatra Mts. was lowered of about 5,5oC. Ice area and its volume calculated for accumulation areas indicate that their relations to one another are nearly identical. It can be evidence for similar precipitation in both the Roztoka and the Rybi Potok drainage basins and an indicator of atmospheric circulation pattern which have determined climate in the Tatra Mts. during LGM.

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.
