Opis:
Detailed geological and palaeobotanical study of about 400 boreholes through Quaternary deposits in eastern Belarus has enabled the recognition of a number of Middle and Late Pleistocene interglacial sites and demonstrated the stratigraphical position of Alexandrian (Holsteinian) and Muravian (Eemian) Interglacial sediments. These stratigraphic markers are separated by a single glacial sequence, corresponding to the Dnieper (Saalian) Glaciation. This contradicts previous views suggesting the occurrence of two glaciations during the Late Middle Pleistocene in eastern Belarus (Dnieper and Sozh). The glacial sediments represent the recession phases of a glacial stage that may be correlated with the Drenthe Substage of the Saalian Glaciation.

Opis:
Lithuanian Pleistocene tills have a multilayered strucure, as established using borehole log data and various analytical methods. Locally it can be observed visually. The structure of the oldest Middle Pleistocene Dzńkija (Elster 1) and Dainava (Elster 2) tills was in vestigated in their areal stratotype in South Lithuania. Logs of three boreholes were chosen for detailed analysis. Their triangular distribution enables evaluation of the variation of till material in N to S and NW to SE di rec tions. Grain-size analysis was performed for tills from all three boreholes and the index of relative entropy of grain-size was calculated. The composition of the Dzńkija and Dainava tills succession indicators advances referable to at least two glaciations and their stages. The Dzńkija tills were formed by glaciers ad vancing from the north across Devonian strata. The Dainava till were left by glaciers advancing from NW across Lower Palaeozoic and Mesozoic rocks. The macroscopically homogeneous upperlayers of the Dzńkija till and the upper and lower layers of the Dainava till have a rhythmic multi layered structure revealed by log and grain-size data. The sedimentological na ture of this rhythmicity is partly shown by variation analysis of the relative entropy of grain-size composition in vertical succession. The index of relative entropy, reflect ing the de gree of mixing, allowed the destination of four zones of entropy (better mixing) in the vertical succession. These zones some times correlate well between widely separated sections. Their presence may be explained by a repeated in put of till material into the basal part of the glacier during its activation (stage, phase).

Early-Middle Pleistocene
Lithuania
Opis:
Investigations have been carried out in order to reconstruct the palaeoenvironmental changes during the earliest Pleistocene interglacials and to establish their relation to global environmental changes. Three sections in east Lithuania exposing the earliest Pleistocene lacustrine deposits lying between the Kalviai (Glacial B, Nidanian?) and Dzūkija (Sanian 1) and between Dzūkija (Sanian 1) and Dainava (Sanian 2) glacial deposits were selected for study. Until now the Šlavė-2 and Vindžiūnai-136 successions were considered to have formed during the Vindžiūnai (Augustovian?, Malopolanian) Interglacial and the Kudrė-915 succession during the Turgeliai (Cromerian IV, Ferdynandovian) Interglacial. Geochemical, palaeomagnetic, magnetic susceptibility, anisotropy of magnetic susceptibility and palaeobotanical proxies were applied to establish the cyclicity and dynamics of palaeoenvironmental change. The data obtained enable the subdivision of the section into units related to changes in the sedimentary environment. The Matuyama/Brunhes boundary and Jaramillo subchron of the Matuyama chron have been recognized in the Šlavė section. The results enable correction of the stratigraphic position of the sections studied. The sedimentation in the Šlavė section took place during the Early Pleistocene, while that at the Vindžiūnai-136 and Kudrė-915 took place during two different Middle Pleistocene interglacials.

Opis:
Two sections (Daumantai-1 and Daumantai-3) in East Lithuania expose Early-Middle Pleistocene lacustrine-alluvial, deposits which lie on a thin Neogene layer and on older Devonian rocks. They are overlain by glacigenic deposits. Geochemical, palaeomagnetic, magnetic susceptibility, plant macrofossil, and diatom investigations were performed to determine the changes in the sedimentary environment. Cluster analysis of the geochemical variables (10 major elements, 16 trace elements, total organic and inorganic carbon) revealed the element groups and factors. The lowermost units are characterized by a major influence of local material and significant fluctuations in heavy mineral content. These fluctuations might reflect short-term climate changes. The transitional units have more expressed trends, especially as regards the trace elements and Zr/Ti. The uppermost units are characterized by a slight influence of local material and small fluctuations in trace elements. The data analysed enable the subdivision of the section into units related to changes in sedimentary environment. The boundary of the Bruhnes/Matuyama reversal in the Daumantai-1 and Daumantai-3 sections was detected by palaeomagnetic studies and enables the stratigraphical correlation of these deposits.

Opis:
Drilling carried out in 2011 at Ferdynandów (E Poland), serving as a stratotype for the Ferdynandovian Interglacial, enabled its re-examination with high-resolution palynological, plant macroremains, and sedimentological analyses. Lacustrine sediments included a record of the Late Sanian 1 (= Elsterian 1) Glaciation, a complete Ferdynandovian succession, and the Early Sanian 2 (= Elsterian 2) Glaciation. Particular similarities in the succession observed between the Ferdynandów 2011 profile and the adjacent sites of the same age in Łuków-3A and Zdany provide a basis for detailed palaeoclimate interpretation. The Ferdynandovian succession of all the three pollen profiles can be clearly divided into two distinct interglacials separated by a sequence of pollen spectra typical of a glacial succession with pollen zones of stadial-interstadial fluctuations. Warm units in the Ferdynandów 2011 succession correspond to climatostratigraphic units of Ferdynandovian 1 and 2, while the cold unit – to Ferdynandovian 1/2. This division can be applied to all Ferdynandovian successions in Poland and allows their correlation with the early Middle Pleistocene Cromerian Complex of Western Europe (Cromerian II Westerhoven and Cromerian III Rosmalen) as well as with Marine Isotope Stages (MIS) 13–15. For each biostratigraphic unit, mean temperatures of the warmest and coldest months, and mean annual temperature and precipitation were reconstructed. For the comparison with the Ferdynandów 2011 pollen diagram the data based on modern pollen analogues for the Łuków-3A pollen diagram were used.

Opis:
The palaeolake from Ossówka, eastern Poland, is an unusual example of basin, in which sedimentation lasted from the beginning of the Holsteinian through several climatic oscillations until the Early Saalian, i.e. over a period of ~70,000 years. This provides us with the opportunity of correlating the dynamically changing events on land with their potential equivalents in the marine profiles. Alkenone-based temperature reconstructions using Uk’37 are an unusual tool in this respect. Nevertheless, as a result, we successfully relate this pollen sequence to the changing SST (sea surface temperature) values in the colder phases of MIS 11. The bipartite Ferdinandovian Interglacial was previously correlated with the upper part of the Cromerian complex (MIS 13 and MlS 15). Having at our disposal limits in the SST alkenone-based record, we clearly identify the stratigraphic position of the second warm phase of MIS 15 and a small fragment of MIS 14. In our opinion, the Rhume Interglacial, identified in Germany, should be located within MIS 13. Using the available orbitally tuned chronology, we also give a substantial input to estimate duration of these terrestrial interglacials, indicating the starting and ending points of their equivalents in the alkenone records.

Opis:
The paper presents a new approach to the Middle Pleistocene lacustrine deposits at the Łuków site (Łuków Plain, E Poland). The resultsof pollen analysis document a rarely found complete Ferdynandovian pollen succession with evidence of two warm periods of interglacial rank and two cold ones. New geological and palynological data are presented and interpreted against a background of earlier researchby Rühle and Sobolewska from 1969, including a comparison with the nearest complete Ferdynandovian succession at Zdany (SiedlceUpland) and with the stratotype section of Ferdynandów. The proposed division of the Łuków sequence into two warm periods separatedby a succession typical of glacial periods has been based on a new division of Ferdynandovian pollen succession applied for the first timeto the Podgórze B1 pollen profile. Two warm units and the intervening cold one in the Łuków pollen sequence correspond to theclimatostratigraphical units Ferdynandovian 1 and 2 separated by the cooling/glaciation (Ferdynandovian 1/2) and can be related to theCromerian Complex.

Opis:
The penultimate (Snaigupele, oxygen isotope stage (OIS) 7) interglacial has proved controversial in Lithuania because of palynological similarities between Holsteinian, SnaigupĹlĹ and Eemian interglacial deposits in the Lithuanian terrestrial record. Furthermore, no warm interglacial period has been recognised between the Holsteinian (OIS 11) and Eemian (OIS 5) in the neighbouring Baltic countries, Estonia and Latvia. In this study, we provide electron spin resonance (ESR) dates of two freshwater mollusc shell samples collected from lacustrine sediments at the Valakampiai site which are thought to be Snaigupele in age. Shells analysed gave mutually consistent dates of 116.0 š 10.8 and 110.0 š 12.1 ka with an average age of about 113.3 ka. These dates are thus significantly younger than OIS 7, and more closely correspond to OIS 5 (Eemian). The possible occurrence of this late Middle Pleistocene OIS 7 interglacial episode in Lithuania and other Baltic countries is evaluated with reference to the nearest and most complete long terrestrial sequences from the central and southeastern parts of the East-European Plain.

Opis:
The geological setting of the Bug-Pripyat interfluve and the close proximity of the source of the Pripyat River to the well-developed Middle Bug River valley suggest that these rivers may have been connected in the past. Analysis of geological cross-sections around the Polish-Ukraine-Belarus cross-border areas together with study of associated Pleistocene palaeoflora shows that buried alluvial deposits of the proto-Bug and proto-Pripyat clearly represent the Preglacial (MIS 103-23), Podlasian/Turskian-Donian/Brest Interglacial (Cromerian I-II; MIS 21-17) and the Mazovian/Likhvinian/Alexandrian Interglacial (Holsteinian; MIS 11c). Their elevated position in mid-eastern Poland suggests the possibility of accumulation by proto-Bug waters flowing eastwards, which determined the formation and development of the lower-lying proto-Pripyat valley system in northwestern Ukraine at those times. The occurrence of the Ponto-Caspian species Lithoglyphus naticoides (C. Pfeiffer, 1828), Borysthenia naticina (Menke, 1845) and Corbicula fluminalis (O.F. Müller, 1774) in the mollusc assemblages of the Mazovian/Likhvinian/Alexandrian Interglacial implies that the main watershed between the Baltic Sea and the Black Sea drainage basins might have been situated in the northern part of the area studied. Presumably its main part was drained by the waters of the proto-Bug catchment connected with the proto-Pripyat and flowing farther to the east towards the Dnieper River entering the Black Sea.

Accumulations of pebbles in the northern foreland of the Carpathians in Ukraine and Poland, composed mostly of Carpathian sandstones, but with a small admixture of Scandinavian rocks, have been known for many years as the ‘mixed gravels’. The occurrence of these gravels in the San–Dnistr and Vistula–Odra interfluves proves that they are of fluvial origin and were deposited by rivers that flowed northwards during the Podlasian (Martonosha and Shirokino) and Ferdynandovian (Lubny) Interglacials. The Scandinavian material was derived from eroded glacial deposits of Nidanian (Turskian) and Sanian 1 (Vyzhivskian, equivalent to Donian) Glaciations.

Opis:
The paper is focused on the palaeographic development of the western part of the Holy Cross Mountains, Poland, during the maximum extent of the Sanian 2 (MIS 12) ice sheet and its retreat. The studies were based on archival cartographic data, coupled with new lithological and petrographic analyses of limni- and fluvioglacial sands, i.e., grain-size composition, quartz grain morphology and heavy mineral analysis, as well as analysis of the erratic material of tills. The results confirm the regional variability of the erratic material in the Sanian 2 tills and point to the long-term development of fluvioglacial sands cover documenting cold climate conditions. They also evidence that the western part of the Holy Cross Mountains was the area where two oppositely directed ice sheet lobes (Radoszyce and Sandomierz) advanced during the Sanian 2 Glaciation and that deglaciation of the area took place in two stages. Huge quantities of meltwater released at that time contributed to the intensification of earlier initiated karst phenomena, as well as filling of the existing caves by fluvioglacial sands.

Opis:
The thickness of Pleistocene deposits in the Kleszczów Graben reach 300 m. Data from these deposits are important for stratigraphic schemes of the Pleistocene of Poland. However, up to now the Mazovian Interglacial deposits were recognized from boreholes only, not from the exposures in the open-cast mine and they comprise incomplete interglacial successions. The present analysis of organic deposits from closed depression exposed on the escarpment of the mine,reveals almost the full pollen succession of the Mazovian Interglacial. The succession started with dominance of birch forest followed by birch-pine and afterwards birch-pine forest with increasing share of alder, spruce and thermophilous trees that led to development of mixed forest which corresponded to climatic interglacial optimum. First there were forests with share of yew which later were replaced by hornbeam and fir. The fir-hornbeam phase closed the climatic optimum. The distinctly colder pine phase following fir-hornbeam phase ended the interglacial succesion of plants in Folwark 93K site. On the basis of changes in diatom composition and relative (percentage) diatom frequency in this site it was determined that the fossil lake sediments represent the diatom succession of the Mazovian Interglacial. The diatom succession from Folwark has been divided into 7 local diatom assemblage zones (LDAZ Fd 1–Fd7). These zones represent four stages of paleolake development and correspond to the local and regional pollen assemblage zones of the Mazovian Interglacial. The Mazovian Interglacial age of the organic deposits from the site Folwark 93K implies the revision of the stratigraphical position of some lithostratigraphic units from the Middle Pleistocene in the Kleszczów Graben. The obtained results indicate also that at least some intensive deformations of the Lower Pleistocene deposits were completed before the Mazovian Interglacial.

Opis:
The new drilling, made in 2011 in the Ferdynandovian interglacial stratotype site in Ferdynandów near Kock (E Poland) allows to carry out high resolution palaeobotanical analyses (including palynological and plant macrofossils ones). The results of the analyses are presented and interpreted against the background of the earlier partition of the ferdynandovian succession (acc. to Janczyk-Kopikowa 1975). A particular attention was paid to the similarity of succession derived from the profile Ferdynandów 2011 with those from neighboring sites in Łuków and Zdany. Very clearly it outlines the division of the three analyzed profiles of the ferdynandovian succession into two distinct interglacials separated by a sediment section bearing the record of the succession typically glacial with its stadial-interstadial oscillations. In the light of the new data from the Ferdynandów 2011 profile, it is clear that the division which was first used by Mamakowa (1996), applies to all ferdynandovian successions in Poland, if only two warm periods were registered in them (formerly known as two climate optima). The warm units in the Ferdynandów 2011 succession correspond to climatostratigraphic units Ferdynandovian 1 and 2, and the cold unit – to Ferdynandovian 1/2 (Lindner et al. 2004). The whole ferdynandovian succession s.l. correlates with the Cromerian complex in the early Middle Pleistocene of Western Europe stratigraphy (Cromerian II Westerhoven and Cromerian III Rosmalen) and marine oxygen isotope stages (MIS) 13–15. The new geological and palaeobotanical data allowed to reconstruct the functioning of interglacial lake and its palaeogeographic context on the stratotype site and its evolution.
Stanowiska z zapisem ferdynandowskiej sukcesji pyłkowej są rzadko spotykane, a zwłaszcza te z zapisem paleobotanicznym dwu okresów ciepłych i dzielącego je ochłodzenia. Na tym tle, na szczególną uwagę zasługuje obszar Południowego Podlasia, na którym zostało rozpoznanych 8 stanowisk z osadami interglacjału ferdynandowskiego. Są one udokumentowane badaniami palinologicznymi (Żarski i in. 2009a; Ryc. 1). Na tym obszarze zlokalizowane jest również stanowisko stratotypowe Ferdynandów B z 1963 roku, dla którego opisano w 1981 roku nową wówczas sukcesję pyłkową, określoną jako sukcesja ferdynandowska (Janczyk-Kopikowa i in. 1991; Mojski, 1985; Janczyk-Kopikowa 1991; Rzechowski 1996).

Opis:
The site at Orłowo Cliff was used to analyse the stratigraphic position and palaeogeographic interpretations of the properties and depositional conditions of two basal tills from the Late Pleistocene. A multi-proxy approach involved lithofacies, petrographic analysis of the fine gravel fraction, analyses of indicator erratics and till fabric. TL dating of intra-moraine deposits was used to determine depositional time frames of tills. The sediment profile at Orłowo Cliff shows a distinct reduction in number of Pleistocene units. Obtained dating results suggest the presence of Middle and Late Pleistocene fluvial units. The main issue discussed is the stratigraphic position of the older till (Unit O-4). It can be assumed that this till was deposited probably during the Middle Weichselian (MIS4). At Orłowo Horn the till of Unit O-4 reveals incorporation of the erratic material derived from an older till in the surrounded area (according to petrographic composition – probably from MIS 8). The younger till (Unit O-6) was deposited in the Late Weichselian (MIS 2). Moreover, the till of Unit O-6 is characterised by a significant shift towards the south-west in terms of the erratic origin in Unit O-4.

Opis:
Extensive collections of land molluscs from the many sections of Middle and Late Pleistocene deposits in the region of the Middle Dniester River were made by Professor Mykola Kunytsia (1925–2002). These collections, now at the Natural Museum, Yuriy Fedkovych Chernivtsi National University, were for the most part analysed, but remained partially unpublished. M. Kunytsia used them for regional reconstructions of palaeolandscapes during various stages of the Pleistocene. In our study, we used these collections to assess the land snail diversity in the region during consecutive stages of the Middle and Late Pleistocene. Our analysis of faunas of cold and warm stages showed that the latter were more diverse. While all or most of the cold stages had many species in common, the faunas of the warm stages were more heterogeneous. Such a feature may play an essential role in Quaternary biostratigraphy.
