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:
Geneza Poj. Mazurskiego związana jest z fazą leszczyńską, poznańską i pomorską zlodowacenia bałtyckiego. Osady lodowcowe w postaci glin, piasków i żwirów o miąższości od 40 do ponad 200 m zalegają na trzeciorzędzie i kredzie. W rzeźbie pojezierza przeważa morena denna. Moreny czołowe występują w 9 ciągach. Dużo jest zagłębień po martwych lodach wypełnionych wodami jezior lub przekształconych w mokradła. Bogata i urozmaicona rzeźba sprzyja rozdrobnieniu mokradeł i oddziaływaniu na nie terenów otaczających. Na Poj. Mazurskim formy terenu mają charakter heterogeniczny i stwarzają warunki do mozaikowatości i zróżnicowania siedlisk. Równina Sępolska, wyraźnie różniąca się od Poj. Mazurskiego, powstała w wyniku deglacjacji zastoiskowej w fazie pomorskiej zlodowacenia bałtyckiego. Tworzy ona obszerną nieckę wypełnioną utworami ilastymi o małej miąższości. W jej powierzchnię wcięte są głęboko erozyjne doliny rzek Łyny i Guberu.
The genesis of the Masurian Lake District is connected with three phases of the Würm glaciation, namely: Leszno phase, Poznań phase and Pomeranian phase. Glacial drifts in the form of clays, sands and gravels with the thickness from 40 to over 200 m cover Tertiary and Cretaceous deposits. Ground moraines prevail among surface features of the Masurian Lake District. Terminal moraines form 9 ridges. There are also numerous depressions of dead-ice origin, filled with lake waters or transformed into marshy grounds. Rich and differentiated surface features are conducive to the fragmentation of marshy grounds and the impact exerted on them by the surroundings. Landforms in the Masurian Lake District have a heterogenic character that reveals in variety and differentiation of habitats. The Sępopol Plain, significantly different from the Masurian Lake District, came into being as a result of deglaciation of ice-dammed lake origin in the Pomeranian phase of the Würm glaciation. It forms a vast basin filled with clay deposits of small thickness. Erosional valleys of two rivers: Łyna and Guber reach deeply into its surface.

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:
Depression in the Quaternary bedrock in the Lower Vistula Region was a main route for the Scandinavian ice sheets advancing into the Polish Lowland. At the end of the Elsterian Glaciation the receding ice sheet dammed the meltwaters in the Lower Vistula Valley and in its vicinity. The Holstein sea presumably occupied the Gulf of Gdańsk as indicated by brackish deposits of this age in the Kaliningrad District. During the Eemian Interglacial an extensive sea bay existed in the Lower Vistula Region. The Lower Vistula Region is a stratotype area for the Vistulian Glaciation (Weichselian), with several ice sheet advances, also before the Last Glacial Maximum.

Opis:
High-resolution grain-size investigations were carried out in two SW Polish loess sections: Biały Kościół (Niemcza-Strzelin Hills) and Zaprężyn (Trzebnica Hills). Each sequence was sampled by using the same methodology and samples were taken at 5 centimeters intervals. The particle size distribution was obtained with a Mastersizer 2000 laser, used for diffraction methods. From the obtained results the basic parameters and grain size indicators were calculated: Mz, Grain Size Index ratio, U-ratio and the percentage content of clay (< 4μm) and sand (> 63 μm). Both loess- soil sequences are composed of interfluve and slope loess facies and consist of five litho-pedostratigraphic units developed during the Late Pleistocene and Holocene: two loess units L1LL1, L1LL2 and three polygenetic fossil soils sets S0, S1 and L1SS1. The distance between these two profiles is about 60 km. Zaprężyn, as a section located more to the north, has almost no lower younger loess and higher level of weathering which could be related to proximity of this site to the Ice Sheet margin. The climate here was more extreme and harsh. What is more,the difference in development of soil L1SS1 can be observed: while in Biały Kościół pedogenesis process was slower and less disturbed than in Zaprężyn. The upper part of L1SS1 in Biały Kościół was deformed by gelifluction, frost heave and other periglacial processes. Mz indicator by the grain-size distribution in these sediments reflects subtle variations in the climatic system. Moreover, in Zaprężyn the content of sand fraction is higher than in Biały Kościół what can be the evidence of short episodes of strong winds during cold period of sedimentation. The aim of this paper is to compare two loess profiles by their stratigraphical and lithological similarities which are result of climate conditions and features of surrounding environment.

Opis:
Near Zamostya in the Volhynian Polesie (NW Ukraine) a first sedimentological attempt was made to explain the origin of glacimarginal forms forming sub-parallel trains. They belong to themost typical elements of the Polesie glacial relief from the Dnieper Glaciation. Lithofacial analysis was used during the research. Based on geomorphological situation of the glacimarginal forms andlithofacial features of their deposits, the forms were classified as end moraines documenting one of the stagnation phases of ice-sheet recession during the Dnieper Glaciation.

Quaternary deposits in the Jeziorsko reservoir vicinity are more strongly disturbed glacitectonically than they thought earlier. Numerous faults, thrusts and folds were documented, but the last ones were only discussed in detail in this article. The greatest deformations were caused by the Warta ice sheet, which was the youngest one in the study area.

Opis:
The heavy-mineral composition of the Weichselian fluvial successions deposited by an ephemeral meandering river and by a sand-bed braided river in the Toruń Basin (central Poland) was analysed. On the basis of a lithofacies analysis, in combination with the composition of the heavy-mineral assemblages, the fluvial processes and river-channel morphology were reconstructed. This allows determining the provenance of the fluvial deposits and the rivers’ discharge regimes. A model is proposed which can explain the changes in the amount of individual minerals in the fluvial sediments of different ages under the conditions of the oscillating Scandinavian ice sheet. The model assumes that, during the ice-sheet advances, the proglacial streams supplied large amounts of heavy minerals that were less resistant to mechanical abrasion. During the main phase of the ice-sheet retreat, the distance between the ice sheet and the Toruń Basin increased, and the amount of non-resistant minerals diminished as a result of sediment reworking in proglacial rivers. Due to the unique location of the Toruń Basin at the front of the Scandinavian ice sheet during the Weichselian glaciation, the heavy-mineral assemblages in the fluvial deposits form a valuable tool for the recognition of the ice-sheet extent.

Studies of the coregonids of Siberia is crucially important for understanding of their origin, taxonomy and evolution. We have analysed electrophoretically some 13 enzyme systems from over 20 samples of East-Siberian coregonids. This paper was intended as an introduction to a number of primary papers that are planned that will describe the biological and genetic characteristics of studied populations.

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.

Stwierdzono wyraźną przewagę skał krystalicznych, brak skał węglanowych oraz dziesięcioprocentowy udział piaskowców. Kwarc zmniejsza swój udział z około 9% we frakcji średniożwirowej do 0,6% we frakcji grubożwirowej. We frakcji 20–60 mm zidentyfikowano narzutniaki fennoskandzkie. Wśród nich były narzutniaki przewodnie z Wysp Alandzkich i sąsiadujących regionów Uppland i dna północnego Bałtyku oraz z obszaru południowo-wschodniej Szwecji (Småland). Wśród narzutniaków wskaźnikowych nie znaleziono ani jednego egzemplarza skały węglanowej.
Sandy and gravel deposits, originating from the ice sheet transgression during the younger stadial of the Warthanian glaciation in Łubienica-Superunki, have been examined in terms of petrographic composition of the middle-coarse gravel fraction and pebble fraction. The distinct predomination of crystalline rocks, no carbonate rocks and a 10% share of sandstones have been ascertained. Quartz has reduced its share from about 9% in the middle-coarse gravel fraction to 0.6% in pebble fraction. The Scandinavian erratics have been identified within the 20–60 mm fraction. Among them the indicator erratics from the Åland Islands, neighboring Uppland, North Baltic bottom and Småland have been found. There was no single carbonate rock found among the so called statistical erratics.

Opis:
Volcanism in eastern Iceland has controlled the changes in glacier- and river-drainage patterns and the sedimentary budget, particularly during the Middle and Late Pleistocene. The glacial extent in NE Iceland appears to be related to the impact of volcanic activity, not only on the ice-stream dynamics, but also on the sedimentary successions. Analysis of the Jökuldalur and Jökulsa á Brù records results in a new interpretation of the changes in ice extent and flow direction for at least the last two glaciations. From MIS 8 onward, the development of the Snæfell volcano apparently forced the ice stream that derived from the Vatnajökull ice cap to take another course; it also affected the offshore sedimentary budgets at the new outlet at Vopnafjördur. The MIS 6 ice sheet was thick and extensive, and associated with an ice-stream diversion to the North. The thick sedimentary complex of palaeolake Halslón was formed close to an outlet of the Vatnajökull, the Brùarjökull, during Termination II and a part of the MIS 5e interglacial. The deposits formed during MIS 5e record two climate optima interrupted by two successive glacial advances correlated with the mid-Eemian cooling. The deposits of the Weichselian deglaciation (Termination I) are much more limited in thickness. During the Last Glacial Maximum and the Late Glacial, glaciers also seem to have been restricted in the Jökulsa á Brù area. Valley glaciers issued from the Brùarjökull re-advanced several times in the Jökuldalur only during at least the Older Dryas, the Younger Dryas and the Preboreal. NE Iceland has undergone considerable deglaciation since the Bølling. In contrast to the conclusions of previous studies, the results presented here are consistent with data on the glaciations in other Nordic regions and can increase the understanding of the mid-Eemian cooling.

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:
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 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:
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:
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:
This paper is a summary of the results of research on the accumulation conditions of the Upper Younger Loess (LMg) in Poland and Bug loess (bg) in Ukraine from the maximum stage (MIS 2) of the Vistulian (Weichselian) Glaciation in central and eastern Europe. These studies included an analysis of the morphological (topographic) situation of the loess cover, its grain size and heavy mineral composition, the preserved structures of loess sedimentation as well as mollusc and pollen analyses of this loess. They revealed that the accumulation of Upper Younger Loess (UYL) might have been more dependent on the prevailing moisture conditions than previously thought. These conditions could have been caused by cold air masses from an ice sheet and warm air masses from the Mediterranean Sea and Atlantic coming together in the Carpathians and the Holy Cross Mountains and favouring the formation of dust storms and precipitation. In this process, a loading of loess dust (formed from local rocks weathering in periglacial conditions) by atmospheric moisture particles was especially significant. The moist substrate not only favoured the periodic development of vegetation and molluscs but also enabled the interception of dust and the accumulation of an increasingly thick loess cover. Westerly and south-westerly winds predominated in the UYL as indicated by the topographic position of loess patches and the mineral composition of the studied loess. Periodically an increased air circulation from the east and northeast occurred.

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:
Stratigraphical and sedimentological analyses of Late Neoproterozoic successions in Lesser Himalaya are combined herein with palaeogeographical considerations and comparisons with equivalent successions in India and South China. The succession starts with the Hazara Formation, which contains complete and incomplete Bouma sequences suggesting its deposition in deep marine turbidite settings. The overlying Tanawal Formation, rich in massive sandstone, shale and siltstone, was deposited in shallow marine conditions, as indicated by the presence of parallel lamination, large scale tabular, trough cross- and hummocky cross-stratifications. The Tanawal Formation facies shift laterally from proximal (south-southeast) to distal (north-northwest). The glaciogenic Tanaki Boulder Bed, overlying the Tanawal Formation, was deposited during the Maronian glaciation. It is equivalent to the Blaini Formation of India, and to the Sinian diamictites of South China. The Abbottabad Formation of Cambrian age overlies the Tanaki Boulder Bed, and is composed of dolomite, chert nodules and phosphate-rich packages; similar successions are documented in India and South China at the same stratigraphical interval. The similarities of the Neoproterozoic successions of Lesser Himalaya (both in Pakistan and India) and South China suggests their possible proximity during the break-up of Rodinia and the assembly of the Gondwana Supercontinent.
