Opis:

Late Holocene deposits containing abundant and well-preserved malacofauna were exposed within the Spa Park in Busko-Zdrój. Molluscan shells were found in sand, dark muds and calcareous muds. Dark and calcareous muds are intercalated by fine-grained sand and peat devoid of malacofauna. Ali these deposits were accumulated on swampy, flat bottom of wide river valley. The result of radiocarbon dating has shown that the formation of the deposits started in the upper part of the Subboreal Phase. Numerous Late Medieval portery shards were found in several topmost profile sections. The identified malacofauna suggests that similar climatic and habitat conditions prevailed throughout the entire sedimentation period. Snails typical of open habitats, accompanied by hygrophilous taxa, play a dominant role. Mesophilous and aquatic taxa occur in accessory proportions, while shadow-loving forms are virtually absent.

Opis:

Limestone rock walls of various inclination form a favourable substrate for the deposition of calcareous tufas that form cone-shaped structures located at the foot of slopes or fill niches within them. Such carbonate deposits usually contain rich and diversified molluscan assemblages, whose composition and structure closely correspond to the ambient environmental conditions in the immediate vicinity. The study of the Pieniny Mountains area revealed 10 sites with such deposits. The identified malacofouna was subjected to detailed analysis. It enabled identification of three types of faunistic assemblages (Bythinella austriaca assemblage, Pyramidula pusilla assemblage, and a shade-loving species assemblage), which are related to the conditions prevailing during the deposition. Tufa cones found in the Pieniny Mountains represent the historic period (Late Holocene). The deposits provide a record of two climatic phases: warmer and colder. The former (Medieval Warm Period) involved the intensified deposition of carbonate material and the rapid growth of tufa cones. The latter – the Little Ice Age – entailed the slow degradation of cones and slower sedimentation of tufas, while the intensified physical weathering led to the increase in the clast material proportion (sharp-edged limestone fragments). Tufas accumulated in the zone unaffected by high anthropogenic pressure and thus represent a record of natural environmental changes during the historic period

Opis:

Palynological and archaeobotanical analyses were conducted on excavated sediments from Tse Dura, a Later Stone Age rock shelter in north-central Nigeria with the aim of reconstructing the environment conditions at the site within the last millennium. From 933 ± 29 BP to 802 ± 29 BP, the environment alternated between Guinea savanna with dry conditions, and secondary and riverine forests with humid conditions. During these periods of environmental fluctuations, the LSA populations engaged in the management of economic plants the most significant of which included Dioscorea spp. Pennisetum glaucum and Elaeis guineensis, and exploited wild plants such as Pavetta crassipes, Sarcocephalus latifolius and Lophira cf. lanceolata for dietary and ethnomedicinal purposes. Around 310 ± 30 BP cal, the environment became very wet after which it was succeeded by a drier period. It was during this period that Sorghum bicolor became prominent, and the environment attained its current status dominated by Guinea savanna elements and secondary forests.

Opis:

The Vistula Lagoon is situated along the south-eastern shore of the Gulf of Gdańsk and is linked with the gulf through the Strait of Baltiysk. Separated from the open sea by the Vistula Spit, the Vistula Lagoon is a shallow body of water with a mean depth of 3 m; the bottom is covered with a layer of mud several metres thick. This article presents a unique, newly discovered locality of tree stumps occurring in situ at the bottom of the Vistula Lagoon. The radiocarbon age of the alder stumps and the top of the peat in which they are rooted is Subboreal. The alder wood was dated to 4770±35 and 3295±35 years BP. The top layers of peat were dated to 4670±40, 4410±35 and 3690±35 years BP. The considerable scatter of the dates indicates the significance of erosional processes during marine transgressions. Radiocarbon dates and pollen analyses indicate that in the late Atlantic – early Subboreal periods, the water level of the Vistula Lagoon was about 3 m lower than it is today. The −2 m level was passed no earlier than c. 3500 years ago; the −1 m level was reached around 2000 years ago.

Opis:

The Falsztyński valley, in the eastern part of Podhale, Poland includes a low terrace spanning the stream channel, the structure of which has been studied in nine profiles. Five gravel levels and five mud levels with plant and abundant mollusc remains are described, temporally constrained by ten radiocarbon dates. The terrace deposits represent the terminal part of the Atlantic Phase and all of the Late Holocene. The mollusc analysis helped identify phases of environmental change, notably one in the Middle Ages connected with intensive settlement activities in the area of Podhale. These include deforestation, affecting mollusc communities with replacement of forest assemblages by open-country species. The gravel levels records increased fluvial activity periods correlated with humid climate phases. It is possible to distinguish five such periods corresponding to the transition of the Atlantic and Subboreal phases, the middle part of the Subboreal Phase, the transition of the Subboreal and Subatlantic phases, the younger part of the Subatlantic Phase, and the last 200 years. These correspond to the periods of increased fluvial activity in the valleys of other Carpathian rivers.

Celem autorów było rozpoznanie osadów pozakorytowych w dolinie środkowej Wieprzy i możliwie dokładne określenie ich wieku oraz miejsc i warunków ich akumulacji na równinie zalewowej. Zastosowano przy tym zestaw metod geomorfologicznych i geologicznych odnoszących się do analizy form występujących na równinie zalewowej i i budujących je osadów.Wcelu określenia ich wieku wykorzystano datowania radiowęglowe, datowania archeologiczne i w odniesieniu do osadów mineralnych – metodę termoluminescencyjną. Analizom poddano osady basenu powodziowego, osady wypełniające różnowiekowe paleomeandry oraz subfosylne i współczesne osady pozakorytowe.
The aim of the study has been to recognize overbank deposits in the middle Wieprza valley, including their precise dating and assessment of local conditions of sedimentation. It is based on geomorphological and geological research of floodplain landforms and deposits. Ages have been determined using radiocarbon method, archaeological dating and, for minerogenic deposits, TL dating. Analyses have been performed on floodplain basin deposits, palaeomeander infills, and subfossil and recent overbank deposits. The studied palaeomeanders have variable infills from various periods of the Sub-Atlantic. They are accompanied by diversified point bar deposits. Floodplain basin deposits have a similar, Sub-Atlantic age. Both types of deposits are overlain by flood deposits, which have accumulated since the early Middle Ages. Contemporary flood deposits of the Wieprza river differ from the sub-fossil ones through more restricted occurrence, resultant from channelization and channel incision. Therefore, in comparison to the pre-channelization period, the extent of floods is smaller and does not encompass the entire Holocene floodplain. Flood overbank deposits form only in the immediate vicinity of the channel.

Opis:

Erosion network formed during the Mikulino-Valdai (Eem-Würm) Interglacial, which is now buried under recent deposits, is the best object of Quaternary geology. One can see its exposures in the Aleksandrov quarry on the Central Russian Upland. The Mikulino-Valdai erosion network certainly needs to be protected as a natural monument. Buried Mikulino balkas (wide flat-bottomed gullies) are unique natural objects, which represent a complete erosion cycle from the surface dissection to its stabilisation, palaeosol formation, and surface levelling as a result of denudation of watersheds and infilling or burying of depressions. On the basis of profiles studied along and across Mikulino balkas, it is possible to trace gradual and catastrophic changes of palaeolandscapes and reconstruct the development stages of topographical forms and soils, associated with climate change within the interglacial-glacial cycle. Over the balka bottom, one can observe the Valdai soil - lithogenic series having no analogues with such a precise and complete stratigraphy within the whole Russian Plain. Besides Mikulino Interglacial palaeosol, there are four buried soils of Valdai interstadial period: Kukuevka, Streletskaya, Aleksandrovka, and Bryansk palaeosols (33,140 š230 BP, Ki-8211). Such a complete set of Late Pleistocene palaeosols is very rare on the East European Plain. In the studied profile we have also found fragments of bones of furred rhinoceros and a prehistoric horse (39,710 š580, Ki-9362).

Opis:

Several tufa complexes are known in the Slovak Karst which is a typical karst area of a temperate climate. This area is built of Mesozoic carbonates, mainly Triassic in age. The karst systems drain carbonate plateaux and lead water to resurgences located in valleys which are up to 300 m deep. Below the resurgences there are Holocene fossil tufa deposits that exceed 12 m in thickness. The tufas include stromatolite, moss, phytoclastic, oncoidal, and intraclastic facies. Extensive barrages which once dammed the upper reaches of the streams were formed in narrow valleys. They are composed predominantly of moss facies and stromatolites, with subordinate oncoidal and phytoclastic facies. Phytoclastic, oncoidal and intraclastic facies are dominant in dammed segments of streams, and include gastropod shells and charcoal fragments. Some small moss cushions are also developed. Barrages and dammed areas formed in a longitudinal fluvial depositional system. Conversely, below resurgences located on plateau slopes tufas of a perched springline depositional system were formed. These comprise deposits of prograding cascades constructed by moss, phytoclastic and stromatolitic facies. Presently, the tufas analysed are inactive. They stopped growing in the Late Holocene time, after which there was abrupt incision of the streams. This caused downcutting into Holocene tufas, in some places reaching Mesozoic bedrock. At present tufa is being precipitated from streams in all the sites studied.

Opis:

The article presents the results of research on spring mire cupolas of the Wolbórka River, a left tributary of the Pilica River. The sedimentary sequence overlies fluvial sands and includes three series of calcareous tufa separated by peat layers. 14C dating indicates that the sedimentation in the spring mire area began in the late Atlantic (AT) and ended at the end of the Subboreal period (SB2). Analysis of lithological features of the sediments has allowed the reconstruction of environmental conditions and their impact on the functioning of the groundwater outflow zone in the late Holocene. The mutual relationship between the peat layers and successive series of calcareous tufa records the changes in humidity conditions resulting from periodic changes in climatic conditions. The sediments of the spring mire cupolas, which are composed mostly of calcite, also contain gypsum and pyrite. The ratio of gypsum to pyrite has proven to be a useful tool for reconstructing humidity condictions. It has become the basis for demonstrating that calcareous tufas are sediments of dry periods, and the deposition of cupola sediments depended on the hydrodynamic regime and flow rate of the springs. The main factor contributing to the deposition of calcite was the equilibration of the groundwater solution with the partial pressure of carbon dioxide in the atmosphere, at low flow dynamics.

Opis:

This study presents the results of a comprehensive geoarchaeological study implemented at an archeological site covering ca. 5 ha near the city of Csorna on the NW part of the Danube Plain, NW Hungary. The site itself exposed a complex fluvial system of an ice age creek with near bank and overbank areas (levee, point bar, back swamp). Spatial distribution of archeological features allowed for the interpretation of differential use of the fluvial landscape by different cultures. According to our data, the referred fluvial system must have emerged during the Late Glacial. At this time, creeks originating from hills to the SE followed a uniform NW trajectory. From the Holocene, small creeks were beheaded turning into inactive flood channels. It was the time when the gradual infilling of the floodplain started. Alternating layers of floodwater coarses and floodplain fines mark recurring floods at our site. These could have been correlated with cooler, wetter climatic phases of the North Atlantic, Western Europe and high stands in Central European lakes. Highest floods are recorded during the Late Bronze and Iron Ages besides the Neolithic. Pollen data enabled us to make inferences on the vegetation as well.

Opis:

The scope of this analysis included fluvial sediments of the low terrace of the Grajcarek stream in the Małe Pieniny Mts. (Western Carpathians). The structure of the terrace has been surveyed in five profiles. The sedimentary sequence includes alternating layers of gravel and calcareous mud with a maximum thickness of up to 2.2 m. A rich and varied malacofauna has been found in the mud. The age of the sediments was determined using the radiocarbon method. The sediments that make up the terrace cover the younger part of the Middle Holocene and the entire Late Holocene. The analysis of the malacofauna has allowed for the characterization of environmental changes. The most important of them dates back to the Middle Ages and is associated with the phase of intensive settlement in the Pieniny Mts.. It is indicated by deforestation and the related change in the composition and structure of malacocoenoses manifested by the replacement of forest communities by ones with open-country species. Gravel horizons are records of flood periods correlated with wet climatic phases. It is possible to distinguish six such phases covering the following periods: 6600–6100 y cal BP, 5500–5100 y cal BP, 4500–4100 y cal BP, 3200–2300 y cal BP, 2000–900 y cal BP and 400–200 y cal BP. They correspond to the periods of increased fluvial activity of rivers, intensification of mass movements, advances of alpine glaciers and the increase in the water level in lakes.

Opis:

The association of changes in mammal diversity with periods of global climatic change is suggestive of a causal relationship. Two important features in the testing of this climatic model are as follows: the timing and the pattern of the diversity changes, and the particular climatic variables examined, since different patterns of evolutionary interactions would be expected depending on different climatic variables. In order to analyse the relationship between climate change and faunal events, we need to establish a set of comparable data. To provide a finely resolved picture of both climatic and faunal events, the last 32,500-years were divided into 13 chronological units of 2,500-years each. The limit of 32,500-years was imposed by the availability of good localities with radioisotopic calibration. Climatic stability was measured in these analyses in terms of cycles per unit of time, the amount of variation in temperature per unit of time, and the magnitude of change between modal temperature of one interval less modal temperature from preceding interval. The data presented here suggest that the primary effect of climatic change is on: (1) levels of extinction (or migration) of large mammals; and (2) diversity and origination (or immigration) of small mammals.

Opis:

Quaternary palynological data are stored in tables which are typical computer database objects. The individual pollen table, in order to be integrated with other tables using computer-based methods, has to be attributed with (1) geographical coordinates, (2) dates attached to each row (sample) of the table, and (3) taxa names, common to all tables, attached to each column. In this paper, integration of individual lists of palynological taxa is shortly described, and some remarks are given on extracting data for selected time slices. The problem of dating of all pollen spectra, while few radiocarbon dates are available in the profile, is considered. Some mathematical models of age-depth relation are proposed, as well as incorporation of information derived from lithology of the profile. The algorithm of integration (averaging) of pollen percentages on the map of Poland is discussed. The techniques of bootstrap and so-called removed residuals are proposed as tools for assessment of reliability of isopollen lines. A possibility of construction of migration (rate of change) maps is also mentioned. The presented algorithm has been used to obtain hundreds of isopollen maps for the Holocene in the area of Poland .

Opis:

In 2005, numerous vertebrate tracks were discovered in carbonate aeolianites in and around the town of Paphos, in the south western part of Cyprus. The main track-bearing exposure is located in a protected archaeological site near the Agia Solomoni Church in side the city of Paphos, where cross-sec tions through tracks are abundant in vertical exposures of the aeolianite along Apostolou Pavlou Avenue. Some exposures show as many as 10 tracks per m2 of vertical exposure. Several additional tracks were found in the extensive subterranean tomb complex, the Tombs of the Kings, just outside Paphos. The aeolian deposit was formed when westerly to southwesterly windsdrove fine- to medium-grained calcareous sand onshore from the beach. This generated low coastal dunes, represented by 1–2-m-thick, cross-bedded sets made up of grainflow and wind-ripple strata, and sand sheets composed entirely of wind-ripple strata. The sediment does not yet have an absolute date, but is considered to be of Late Pleistocene to Early Holocene age, as are many other coastal aeolianites in the Mediterranean area. The Late Pleistocene endemic fauna in Cyprus was limited to the dwarf hippopotamus Phanourios minor Desmarest, 1822, the dwarf elephant Elephas cypriotes Bate, 1902, a small carnivore Genetta plesictoides Bate, 1903, and (possibly) humans. The exposed tracks are 5–15 cm in diameter, with a few tracks up to 23 cm in size. This range of size correlates well with the estimated foot size of dwarf hippopotami and dwarf elephants. This low-diversity, endemic is land fauna provides a unique opportunity to correlate tracks with trackmakers.

Opis:

Evidence of earthquake-induced liquefaction features in the Acequión river valley, central western Argentina, is analysed. Well-preserved soft-sediment deformation structures are present in Late Pleistocene deposits; they include two large slumps and several sand dikes, convolutions, pseudonodules, faults, dish structures and diapirs in the basal part of a shallow-lacustrine succession in the El Acequión River area. The water-saturated state of these sediments favoured deformation. All structures were studied in a natural trench created as a result of erosion by a tributary of the Acequión River, called El Mono Creek. They form part of a large-scale slump system. Two slumps occur in the western portion of the trench and must have moved towards the ENE (70°), where the depocentre of the Boca del Acequión area is situated. Considering the spatial relationship with Quaternary faults, the slumps are interpreted as being due to a seismic event. The thickest dikes in the El Mono Creek trench occur in the eastern portion of the trench, indicating that the responsible earthquake was located to the east of the study area, probably at the Cerro Salinas fault system zone. The slumps, sand dikes and other soft-sediment deformation features are interpreted as having been triggered by earthquakes, thus providing a preliminary palaeoseismic record of the Cerro Salinas fault system and extending the record of moderate- to high-magnitude earthquakes in central western Argentina to the Late Pleistocene.

Praca referuje wyniki badań nad zmianami klimatycznymi w Arktyce, jakie zachodziły od początku późnego glacjału do momentu rozpoczęcia obserwacji instrumentalnych. Większą uwagę skupiono na zmianach klimatycznych, jakie miały miejsce w ciągu ostatnich 2500 lat. Zwrócono również uwagę na synchro-niczność zmian klimatycznych w Arktyce i wyraźnie rysujące się związki między zwiększonym dopływem wód atlantyckich do Arktyki, a kolejnymi fazami ociepleń.
This work presents an overview of literature devoted to presenting the results of research into climatic changes in the Arctic noted from the beginning of Late Glacial up to the moment when instrumental observation started. Greater emphasis was put on climatic changes which occurred during last 2000-2500 years. It was noted that the climatic changes in the Arctic were synchronical, that the rate of changes from the cooler seasons to the warmer ones and in the other way was fast and that the correlations between the increased import of the Atlantic waters to the Arctic and the following phases of warming were clear. The final part presented how the intensity of the Atlantic waters inflow influences the way the ice cover controls the mechanism of climatic changes in the Arctic.

This study combines high-resolution planktonic foraminiferal eco-biostratigraphy and palaeoclimatic data from the high-sedimentation-rate core J PC-26 from the northwestern margin of the Gulf of Mexico (GoM). The eco-biozones recognized (GOMPFE1-12) being correlated with published Mg/Ca-based sea surface temperatures. This updated palaeoclimatic and stratigraphic reference record facilitates correlations with the Greenland ice core events and their climatic relationships, and also provides a solid stratigraphic framework for correlations with other palaeoclimatic and palaeoceanographic records in the circum-GOM/Caribbean region. This multidisciplinary approach underlines the utility of supporting conventional dating methodologies with different constraints, and further reveals a powerful tool for reliably correlating marine records between comparable deep-sea marginal settings and coeval sequences of this region.

Opis:

Interdisciplinary investigations (pollen and diatom analysis, 14C dating and geological-geomorphological and archaeological data) around Lakes Duba and Pelesa, in SE Lithuania, have elucidated the environmental history and human impact throughout the Late Glacial and Holocene. Aerial photograph interpretations indicate that both lakes are residual basins of one Post-Glacial palaeolake outside the morainic relief of the Nemunas (Weichselian) Glaciation. Pollen assemblages from lacustrine deposits date back to the Older Dryas (Lake Duba) and Alleröd (Lake Pelesa) and cover all chronozones of the Post-Glacial. Diatom analysis has illustrated the palaeoecological conditions in the lakes and helped reconstruct successive water levels throughout the last 12300 radiocarbon years. Diatom abundance and the distribution of the planktonic, benthic and epiphytic species suggest a lowering of Lake Duba and Lake Pelesa at (e.g.) 11900-10900 14C BP, (e.g.) 10000-8100 14C BP and (e.g.) 3700-2500 14C BP. Pollen data suggest that the earliest signs of human impact and local forest clearances data from about (e.g.) 8400-8300 14C BP. The first record of cereal pollen in sediments dates from earlier than (e.g.) 6000 14C BP. Therefore, agriculture was introduced into the area not earlier than the second half of the Midle Neolithic, at about (e.g.) 5000-4400 14C BP. Continous indications of agriculture and progressive clearing of woodland is consistent with the increasing role of a farming economy during the Bronze Age. Since the 1800-1900 14C BP formation of an open canopy, increasing soil erosion and changes in vegetation emphasize the remarkable human impact on the environment.

Opis:

Zmiany klimatyczne, a za tym daleko idące zmiany środowiska w późnym glacjale i holocenie na obszarze południowego Bałtyku mogą być wyjaśniane także przez badania fauny mięczaków. Na obszarze południowego Bałtyku w okresie późnego glacjału występowały gatunki słodkowodne wskazujące na klimat zimny, takie jak: Armiger crista f. cristatus, Gyraulus laevis, Lymnaea peregra, Pisidium casertanum, Pisidium casertanum f. ponderosa, Pisidium milium, Pisidium nitidum, Pisidium obtusale f. lapponicum, Valvata cristata, Pisidium conventus. Akumulacja jeziorna w słodkowodnych zbiornikach strefy przybrzeżnej kontynuowała się w okresie wczesnego holocenu. W tym czasie oprócz gatunków słodkowodnych, zimnolubnych pojawiły się gatunki mięczaków i małżoraczków słodkowodnych, o wyższych wymogach termicznych (Bithynia tentaculata, Physa fontinalis, Pisidium amnicum). Świadczy to o ociepleniu się klimatu w okresie preborealnym. Zrastanie przybrzeżnych zbiorników rozpoczęło się w okresie borealnym i trwało również w okresie atlantyckim. W tym czasie miały miejsce wlewy wód morskich do zbiorników. Wskaźnikiem tego jest liczne występowanie morskich gatunków takich jak: Hydrobia ulvae, Hydrobia ventrosa, Cerastoderma glaucum, Mytilus edulis, Macoma balthica. W osadach piaszczystych w okresie subborealnym i subatlantyckim zdecydowanie przeważała fauna morska.

This study provides a vegetation and climate history of an alpine wetland in the centre of China’s Qinghai–Tibetan Plateau (QTP) over the last 14.8 ka. High resolution climate proxies include vegetation (pollen), geochemical (Ba, Rb, δ13C) and physical (particle size and magnetic susceptibility) data; optically stimulated luminescence (OSL) and AMS radiocarbon dating were used to reconstruct the environmental changes in the wetland ecosystem. Based on physical and geochemical proxies, the sucession divided into five stratigraphic units encompassing time intervals of 14.76–14.31, 14.31–13.17, 13.17–4.47, 4.47–0.51 and 0.51–0 ka. The average sedimentation rate of all these units was 0.098 mm/a. The study showed that this ecosystem was sensitive to climate change.

Opis:

Late Vistulian and Holocene mollusc-bearing deposits, developed as solifluction sediments, travertines and calcareous tufa, occur in a valley of a small stream on NE slopes of the Ostrysz Hill near Małe Ciche in the Podhale Basin (S Poland). Several types of rich and differentiated mollusc assemblages, corresponding to consecutive phases of the evolution of climate and palaeogeographical conditions during the Late Vistulian and Holocene, were found in eleven profiles.

Opis:

Sediment geochemistry and lithology were studied in Gostyń Lake in the eastern part of the Myślibórz Lakeland (part of the Western Pomeranian Lake District). The research was undertaken because relatively shallow lake basins without ground supply contribute to the intensification of water circulation through evaporation. Late Glacial and Holocene phases in the evolution of Gostyń Lake were reconstructed based on selected geochemical indicators (Fe/Mn, S/Fe, Na/K, Mg/Ca, Cu/Zn, Na+K+Mg/Ca, Fe/Ca) as well as on the presence of human activity (Stone Age, Bronze Age, Early Iron Age and Roman Period). Also, the geochemical and archaeological data were correlated. Generally, the lithogeochemical composition variability in the Gostyń Lake deposits was found to be controlled by changes in: 1) the climate, related to the biogenic accumulation environment, 2) land cover in the Late Glacial and Holocene, and 3) human activities. Principal Component Analysis (PCA) revealed four major variable groups responsible for the changes: hydroclimatic variations which determined the type of sedimentary conditions during the Holocene climate optimum; changes in the organic matter provenance (along with conditions favouring sulphide precipitation); and denudation processes in the Gostyń Lake catchment. The methods used allowed the distribution of ancient settlement to be traced. Interpretation of the geochemical indicators (Fe/Mn, Cu/Zn, S/Fe, Ca/Fe) should involve many more factors which, in the relevant literature, are treated as measures of changes in redox conditions

Opis:

This paper presents the results of absolute dating and biostratigraphical analysis carried out for alluvial sediments of an abandoned Starunia ozokerite mine located in the Velyky Lukavets River valley, in which large mammal remains were discovered in the first half of the 20th century. The sediments build up three terrace levels. The highest one, up to 8 m high (terrace II), is likely to be associated with a stage of aggradation, as well as with a short episode of valley broadening, which occurred in the Weichselian Late Pleniglacial. The lower one, 4 m high (terrace I), is most likely to be linked with the Holocene, despite a considerable transformation of its top due to mining activity. The lower part of this terrace cover bears coarse-grained channel sediments dated to 120.6-58.9 ka BP (Eemian Interglacial?-Early Pleniglacial - OIS 5e, 4 and 3), and overbank (distal floodplain) mud with intercalations of biogenic deposits (peat, peat mud and biogenic mud). The overbank deposits are dated to 48.2-11.11 ka BP (Glinde Interstadial?-Younger Dryas, OIS 3-2) and are overlain by Holocene (OIS 1) mud and biogenic deposits. In boreholes drilled in the vicinity of the present-day river channel, younger sediments occur more frequently. These include sediments originating from the Late Weichselian overlain by Holocene sediments. However, sediments originating exclusively from the Holocene are infrequent. The deposition of sediments took place in specific conditions of a permanent saturation of the environment with brine, petroleum and thickened bitumen. In the longest period of deposition (48.2-1.27 ka BP), ephemeral swamps, ponds and lakes were developed in different parts of the floodplain. They were marked by the presence of: Juncus glaucus/effusus, J. articulatus, Typha sp., Batrachium sp., Potamogeton filliformis, Bidens tripartita, Ranunculus sceleratus and Phragmites communis, as well as by halophytic species, like: Zannichellia palustris, Triglochin maritimum, Schoenoplectus tabernemontani, Puccinelia distans and Eleocharis palustris. Rhythmic oscillations between cold and warm climatic conditions, typical of the Weichselian age and well identified in Western Europe, are here marked by the changes of plant communities (woody assemblages passing into steppe and tundra), but are not noticeably recorded in the sediments of the Velyky Lukavets River. This shows that the greatest part of the discussed period involved the formation of poorly differentiated silty overbank sediments with intercalations of biogenic sediments. However, the variability of sediments provides evidence for extreme events which occurred in the Holocene.

Opis:

The glacial history of the Svalbard archipelago is often a hot topic for researches, but the articles usually refer to a particular piece of Svalbard. The authors of this work studied many scientific articles based on the researches to find and collect this history.Svalbard archipelago is located in the Arctic, at the edge of the continental shelf of Europe. The end of shelf boundary noted occurrence of ice caps in the past glaciations. In turn, the main elements of the landscape of the archipelago are glaciers that are currently in a recession. Spitsbergen (the biggest island of the archipelago) sets the limit of Pleistocene glaciations, and the current state of glaciers allows determining the place where the recession is intense.The main aim of the authors in this study is to show this history only from the late Vistulian to the late Holocene (the beginning of 21st century). Interstadials and Stadials start time varies, as their duration in different places, according to various authors. It is very hard to collect all information and describe this history. By knowing the history of glaciation, we can distinguish in the late Vistulian: Last Glacial Maximum (LGM), Bølling/Older Dryas/Allerød and Younger Dryas (YD). LGM was the stadial in which was the maximum extent of ice sheet in late Vistulian. After this period, ice sheet began to retreat from the continental shelf. In turn, YD was the stadial in which the last advance of glaciers took place, about 11 000 years BC. In the Holocene we can distinguish Holocene Climatic Optimum (in the meantime short Cooling Holocene), Revdalen Stadial, Medieval Warm Period, Little Ice Age (LIA) and 20th century warming. The maximum extent of glaciers in Holocene was in LIA. In LIA, the extent of glaciers was bigger than in YD. In 20th century a warming started and continues until now.
Svalbard jest obszarem, gdzie zachowały się w różnym stopniu „ślady” zdarzeń glacjalnych. Dowodami ich wystąpienia są między innymi osady oraz formy glacjalne i fluwioglacjalne (np. Boulton 1979; Boulton i in. 1982; Landvik i in. 1998; Mangerud i in. 1998; Pękala, Repelewska-Pękalowa 1990; Lindner, Marks 1993ab; Ingólfsson, Landvik 2013). Bliskość tego obszaru w stosunku do centrów zlodowaceń powodowała, że kolejne epizody glacjalne „zamazywały ślady” poprzednich, niszcząc je lub przekształcając (np. Landvik i in. 1992; Mangerud i in. 1998; Zagórski 2007). Po deglacjacji następował zazwyczaj okres intensyfikacji działania procesów nieglacjalnych (paraglacjalnych), np. morskich, peryglacjalnych (Mercier, Laffly 2005; Strzelecki 2011; Zagórski i in. 2012). Stąd najlepiej zachowały się pozostałości najmłodszych zdarzeń i epizodów glacjalnych, np. małej epoki lodowej (np. Baranowski 1977abc; Lindner Marks 1993b; Werner 1993; Wójcik, Ziaja 1999; Reder 1996ab;  Birkenmajer, Łuczkowska 1997; Svendsen Mangerud 1997; Zagórski i in. 2008, 2012; Rodzik i in. 2013).

Opis:

In the area of the southern Baltic Sea, the largest and most violent changes in water level took place in Late Glacial and Early Holocene, during the period between 13.0-8.5 ka BP. These changes depended on the varied glacio-isostatic movements between the northern and southern parts of the Baltic Sea, the glacio-eustatic increase in the ocean level and the closing or opening of the connection between the Baltic Sea basin with the ocean. During the Late Glacial and Early Holocene, the sea level changed within an amplitude as wide as 25-27 m. In some extreme cases, the sea level could have fallen at a rate of about 100-300 mm/a, the sea level rise rate reaching up to about 40-45 mm/a. In Late Glacial and Early Holocene, there were three transgressions: during 12.0-11.2, 11.0-10.3 (the Baltic Ice Lake) and 10.2-9.2 ka BP (the Yoldia Sea and the Ancylus Lake). There were also three regressions, setting on 11.2, 10.3 and 9.2 ka BP. During regressions, depending on the real drainage rate and the local gradient of the bottom inclination, the land possibly grew at a rate of 0.3 to 4 km per year. During transgressions, rate of shoreline migration could reach in some cases up to 150-200 m per year. These processes took place on the surface of the sea bottom currently located at the depth of c. 55 to 25 m below sea level and from 30 to 60 km away from the present-day southern coast of the Baltic Sea. Rapid changes of shoreline position are recorded in progradational barrier structures and in the erosion surfaces of the glacial till and glacio-marine clays.

Opis:

The paleoecological research of biogenie sediments sampled in the different lake-mire ecosystems of the Łęczna Włodawa Lake District were the basis of studies on hydrological changes during the Late Glacial and Holocene. The lithological differentiation (spatial and temporal) of lacustrine and mire sediments in the studied sites indicates that the hydrological changes were of local nature. The investigations also evidence a specific functioning of the lakes in this region. Lake basins were formed as a result of the ground ice degradation and the transformation of groundwater circulation in the Late Glacial. The total area of lakes in the Lake District was the largest from the Younger Dryas to the Subboreal chronozone. The gradual lowering ofwater level during the early Holocene resulted in the transformation of sedimentation process, and in the development of typologically differentiated mires and lacustrinc-mire complexes.

Opis:

Slope deposits developed on calcareous sandstone and limestone formations in the eastern part of the Podhale Basin (Carpathians) were studied. In total, the analysis included fifteen profiles of such sediments, which revealed the presence of abundant malacofaunas comprising 39 mollusc species. Five faunistic assemblages differing in species composition and structure were defined in the material studied. Individual assemblages correspond to different climatic and environmental conditions, thereby making it possible to interpret the features of the sedimentary environments and specify the age of the deposits. Faunas with Pupilla loessica and Pupilla sterri containing species typical of loess formations are characteristic of deposits from the coldest phase of the last Glacial period (MIS 2). A fauna with Vertigo genesii, with a large proportion of cold-loving and moisture-loving taxa, is typical of the Younger Dryas. Associations that are dominated by shade-loving species, with Discus ruderatus and Discus perspectivus, correspond to the early and middle Holocene respectively. The investigations show that malacological analysis can be successfully applied to the research into slope deposits, enabling both the depositional conditions and the age of the sediments to be determined.

The Durne Bagno peat bog is the eastern, peripheral part of a large marshland complex in the Lublin Polesie. Limnic biogenic deposits occurring directly on mineral deposits are up to 8.5 m thick. They exhibit great vertical facial variability and small lateral differentiation. This indicates that the conditions of sedimentation/sedentation were similar in the whole basin in particular time intervals. The chronostratigraphically-correlated sequence of sediments allows reconstruction of the geosystem evolution in recent 13 ka BP. In its entire Late Glacial and Holocene history two basic stages may be distinguished: lacustrine (OD — middle AT) and mire (middle AT — present time)

Późnoglacjalne i holoceńskie węglanowe osady jeziorne rozwinięte jako kredy jeziorne i gytie wapienne są bardzo rozpowszechnione na obszarze północnej Polski. Stanowią one wypełnienia paleojezior, które tworzyły się w okresie deglacjacji ostatniego lądolodu. Utwory te są zazwyczaj przykryte torfami. W omawianych osadach została znaleziona bogata i urozmaicona malakofauna. Analizie malakologicznej zostały poddane profile pochodzące z 54 stanowisk opracowanych przez różnych autorów. W całym badanym materiale zostało wydzielonych 18 zespołów mięczaków reprezentujących trzy typy siedlisk: środowiska lądowe, środowiska okresowych zbiorników wodnych i środowiska stałych zbiorników wodnych. Skład i struktura tych zespołów pozwalają na scharakteryzowanie klimatu i zróżnicowania siedlisk. Następstwa asocjacji malakologicznych umożliwiły zdefiniowanie trzech typów sekwencji malakologicznych. Na podstawie tych sukcesji został opracowany schemat ewolucji zbiorników jeziornych w czasie późnego glacjału i holocenu na północy Polski.
Late Glacial and Holocene mollusc-bearing deposits developed as lacustrine chalk and/or calcareous gyttja are widespread in Northern Poland. They fill up water bodies formed during the final stage of deglaciation. These sediments usually contains rich assemblages of molluscs. Calcareous lake deposits and it's malacofauna were described in detail by several authors in 54 localities. Eighteen communities of snails and bivalves have been distinguished. They are represents three types of environment: land, temporary water bodies and permanent water bodies (lakes). The composition and structure of malacocenoses reflect changes of the climate and differentiation of habitats. Three types of malacological sequences can be define. The scheme of evolution water bodies during the Late Glacial and Holocene in Northern Poland was elaborated based on successions of molluscan communities.

Opis:

Results of a geomorphologic study as well as radiocarbon and pollen analyses of sediments in small basins of the Jasło-Sanok Depression (Western Carpathians) are summarised. Floors of these basins, carved in soft shale-sandstone Krosno Beds, are covered with channel fluvial deposits and oxbow-lake sediments with lake chalk and peat accumulated in the Late Vistulian and Holocene. Since the early Atlantic Phase (ca 8,400–7,900 BP) the apparent acceleration of overbank (flood) deposition intermitting the peat accumulation is observed. The plant succession includes the Late Glacial (pre-Allerød, Allerød and Younger Dryas) with coniferous park forests, through mixed deciduous forests of the Holocene with elm, hazel, oak and lime as well as spruce-elm forests with alder in wetlands, up to present-day hornbeam forests (Tilio-Carpinetum of various types) and extra-zonal Carpathian beech forests (Dentario-Glandulosae- Fagetum). Abies alba (fir) is frequent in both these association types. First evidences of synanthropic plants that prove presence of prehistoric man appeared in the Subboreal Phase. The oldest radiocarbon date 13,550±100 BP (Gd-7355) [16,710–16,085 b2k], from a bottom part of the Humniska section is probably overestimated. This is indicated by palynological data, which suggest attribution of this section to the older Allerød. Small thickness of gravel blanket from the Plenivistulian termination and the beginning of the Late Vistulian, as well as large areas devoid of weathering and solifluction covers indicate that during the Plenivistulian weathering processes and removal of silt-clay material predominated in the basins. In that time the deflation was among important processes, which is proved by deflation troughs, faceted cobbles and thick covers of the Carpathian type of loess. The Besko Basin has pre-Vistulian tectonic foundation, while landforms of its floor are of erosion-degradation origin and formed during the last Scandinavian glaciation. In the Holocene the basin floors were overbuilt with fluvial deposits up to 8 m thick.

Opis:

This study aimed to reconstruct environmental changes in the Wkra River Valley near Bielawy Gołuskie (central Poland) based on geochemical, palynological and subfossil Cladocera analysis of deposits filling a palaeo-oxbow lake. Two sediment boreholes collected from the palaeochannel bend (BG-1) and neck (BG-2) include full sequences of organic deposits lying on clastic deposits. The lower part of the BG-1 borehole contains gyttja that accumulated during the Younger Dryas and the Preboreal, which is covered by reed peat of Preboreal and Boreal age. On top of this is alder peat that accumulated during the Atlantic. The ages of the gyttja and peat were confirmed by both radiocarbon dating and palynological analysis. The peats are characterized by a significant content of organic matter, which is relatively stable over time. This indicates a low intensity of mechanical denudation in the catchment, which is supported by low concentrations of aluminum and potassium. Calcium values greatly exceed these elements, suggesting that the lake was mainly fed by groundwater. Variation in trophic conditions over time is indicated by a vertical variability in the content of nitrogen, as well as by the Cladocera population. The strong decomposition of peat in the top layer of the mire, and increased concentrations of phosphorus and heavy metals, testify to increasing human activity during the most recent time periods.

Opis:

Geochemical and plant macrofossil analyses of the Żabieniec mire deposits and the palaeoenvironmental changes they record of the past several thousand years constitute an important source for palaeogeographical reconstruction of the Polish Lowland. We describe the phases of the basin’s development from the final part of the Plenivistulian (MIS2), through the Late Glacial and the entire Holocene, encompassing changes determined by both regional and global factors in the surrounding environment, and habitat transformations in the limnogenic mire. The kettle-hole infill of the Żabieniec mire is the only documented example in Central Poland of a succession of biogenic deposits exceeding 10 m in thickness in such a setting. Deposition initially took place in a lake environment, which led to a shallowing of the lake that persisted until the end of the Mesoholocene.

Opis:

Na torfowisku Taboły (Puszcza Knyszyńska) wykonano łącznie 20 odwiertów, charakteryzujących jego budowę geologiczną. W analizowanym materiale biogenicznym rozpoznano szczątki wegetatywne i generatywne 94 taksonów roślinnych. Rozwój torfowiska rozpoczął się w starszym dryasie, kiedy to zatorfienie zostało zainicjowane przez zbiorowisko Scorpidium scorpioides. Na przełomie allerod/młodszy dryas rozwinął się zbiornik wodny, którego zanik przypadł na przełom późnego glacjału i holocenu. W okresie preoborealnym na torfowisku dominowały zbiorowiska mchów brunatnych z udziałem brzóz krzewiastych oraz szuwary wielkoturzycowe. Od schyłku okresu subborealnego postępowała oligotrofizacja siedlisk, co doprowadziło do przekształcenia się złóża w torfowisko przejściowe. Spadek poziomu wód gruntowych znalazł odzwierciedlenie w podwyższonym stopniu rozkładu torfu, w najmłodszej fazie rozwoju torfowiska. Tempo akumulacji torfu było wówczas najmniejsze.
In Taboły mire (the Puszcza Knyszyńska Forest) 20 drillings were made altogether. Vegetative and generative remains of 94 plant taxa were recognized. According to radiocarbon dating, the mire started to develop in the Late Glacial period. In the Preboreal period brown moss communities with and admixture of shrub birches and sedge rushes dominated in the mire. At the end of the Subboreal period habitat oligotrophication proceeded which resulted in the transformation of deposits into transitional bog. Groundwater decline was reflected in a higher intensity of peat decomposition. The rate of peat accumulation was then the lowest.

Opis:

Benthic and planktic foraminiferal assemblages from two sediment cores (2000 m depth, 44°33′N-2°45′W) were analyzed to first compare modern and dead faunas and next to study changes in the hydrology of the southeastern Bay of Biscay (SE BoB) over the last 12.8 cal ka BP. Considering benthic ecosystem characteristics, the first part of the paleorecord (12.8–7.6 cal ka BP) is composed of laminated sediments that may have resulted from turbiditic overflow events, whereas occurrences of transported species (e.g. Nonionella sp., Cassidulina carinata) attest of continental influence at the core location. After 7.6 cal ka BP, the sediment becomes bioturbated concomitantly to the stabilization of the sea-level. The benthic foraminiferal fauna is largely dominated by Uvigerina peregrina suggesting a high seasonality with seasonal pulsed organic matter fluxes to the seafloor. On the other hand, the planktic foraminiferal composition indicates that surface water masses were under the influence of the polar front in the early record, which retreated at about 11.5 cal ka BP. The early Holocene is characterized by relatively warm and stratified water masses at 8.4–4.8 cal ka BP. The last 4.8 cal ka BP records a gradual sea surface water cooling trend and enhanced foraminiferal production from ~2.6 cal ka BP until present. The early (12.8–10.5 cal ka BP) and late (2.3–1.7 cal ka BP) Holocene are characterized by the presence of the planktic species Globigerinoides ruber probably caused by intrusions of the Iberian Poleward Current (IPC), and a negative state of the North Atlantic Oscillation (NAO).

Opis:

The paper presents the results of sedimentological and biostratigraphical analyses from the Resko Przymorskie Lake spit (NW Poland), supported by radiocarbon datings. The study has aimed to recognize the geological structure of the spit and its base and to recognize the palaeoenivronmental changes. Nine sedimentary series composing the Resko Przymorskie Lake spit have been distinguished (I–IX). The oldest sediments are the Vistulian Glaciation till (series I) and fluvioglacial sand and gravel (series II). In the Early Holocene, in the study area there was a river valley (series III) followed by a shallow water basin (series IV), which was replaced by a peat bog (series V). In the Atlantic (7.4 ka cal BP), the water level rose (Littorina transgression) and accumulation of lagoonal sediments started (series VI). Biostratigraphic analysis of deposits in series VI indicates a marine influence. In the Atlantic and Subboreal, the spit moved southwards and fine sand (series VII) was deposited on lagoonal gyttja and silt (series VI). In the western part of the study area, peat accumulated (series VIII), dated at 6.7 ka cal BP (Late Atlantic). The youngest series IX is composed of aeolian fine sand in white dunes that formed in the last 400 years.

Opis:

Na podstawie badań terenowych przeprowadzonych po wschodniej stronie rynny jeziora Jasień oraz z wykorzystaniem literatury z zakresu paleogeografii, autor dokonał rekonstrukcji przebiegu procesów stokowych, które zaszły w późnym vistulianie i holocenie. Badania pozwoliły wyróżnić etapy kształtowania się dolinek erozyjno-denudacyjnych i powstawania osadów stokowych. Wykazały one również wpływ działalności człowieka na rozwój wymienionych zjawisk i pozwoliły umieścić je w ramach czasowych.
The Jasień lake trough is situated in northern Poland, in the eastern part of West Pomeranian Lakeland. Main geomorphic features of the area developed during the advance of the Bytów ice lobe and its subsequent decay, ca. 16,000 years ago. Research focused on the evolution of erosion-denudation landforms and characteristics of slope deposits was based on detailed field work, which involved excavation of numerous test pits within dry valleys dissecting the eastern slopes of the Jasień lake trough. The onset of valley morphogenesis can be dated for the period immediately preceding the Oldest Dryas. Seasonal concentrated runoff caused initial dissection of the topographic surface sloping towards the lake. Later on, probably in the Oldest Dryas, solifluction and surface wash began to re-shape valley sides, which have been later transformed by different processes and yielded different types of sediments. During warmer periods, particularly at their waxing stages, valley floors were subject to dissection, as testified by pavement surfaces, and stored sediments moved down the valley. Slope deposits formed mainly during cooler stages of the Vistulian and at the turn of the Holocene. Lithologically, they represent stony-gravel horizons related to solifluction and sandy deluvial series. The period between the Preboreal and Subatlantic witnessed little geomorphic activity and is recorded in well developed palaeosols. Slope activity resumed in the early Middle Ages, under the influence of people.

Opis:

This paper presents the results of geochemical analysis performed for the more-than-10-m-long core of sediments derived from Lake Nowowarpieńskie. Contrary to what its geographical name would suggest, it is in fact a peripheral bay  of the Szczecin Lagoon (NW Poland). A characteristic feature of the sedimentary cover of this water body is the several-metre-thick layer of lacustrine chalk, which is unique in the lithology of the sediments of today's Szczecin Lagoon. This sediment has been analysed using atomic absorption spectrometry (AAS), energy-dispersive X-ray spectroscopy (EDS) and scanning electron microscopy (SEM) imaging. The chalk sediment from Lake Nowowarpieńskie is of chemical origin, bearing no fragments of vascular plants, but only traces of C-org in the form of small plant remains. The analysis of individual crystals using the EDS method also show Ca contents of over 99%. SEM images reveal that the sediment is characterised by a loose, disordered pack-ing of individual crystals, often combined to form aggregates with a tabular structure. The individual calcite grains are usually a few micrometres in size, while developed ones are mostly hypidiomorphic and show signs of corrosion. The sedimentation of the lacustrine chalk indicates that the post-glacial natural development of this part of what today constitutes Szczecin Lagoon differed from that of the rest of the lagoon. This sediment was deposited in a shallow but fertile isolated lake. The full profile of sediments from Lake Nowowarpieńskie reveals its distinct bipartite character, indicating two main stages of its evolution: carbonate and post-carbonate. In the first, the water body showed similarities to the neighbouring lakes of the Wkrzańska Plain. Its evolution was driven by climatic factors. The second stage was initiated by a palaeohydrological factor – Littorina transgression, which resulted in the lake being included into the hydrological system of the Szczecin Lagoon.

Opis:

Wykorzystując wcześniej opublikowane prace oraz materiały jeszcze nieopublikowane, autorzy przeprowadzili ocenę danych geologicznych i paleobiologicznych zebranych w rynnie jeziora Jasień z punktu widzenia paleogeograficznego, a przede wszystkim paleohydrologicznego. Analiza ta wykazała trafność większości uwag zawartych we wcześniejszych pracach W. Florka i jego współpracowników traktujących o zmianach poziomu jezior występujących na dnie rynny jeziora Jasień. Nowsze dane paleobiologiczne i geologiczne pozwoliły na uściślenie wcześniejszych danych i ich korektę.
The paper focuses on palaeogeography and, dominantly, palaeohydrology of the Jasień lake trough. The analysis is based on re-assessment ofpreviously published geological and palaeobiological data, as well as on new, yet unpublished materials. Geomorphic evidence for lake level changes within the trough includes lake shore terraces, relict cliffs from earlier stages of higher lake stands, small and flattened coastal bars, plains built of limnic and palustrine deposits, and deltas formed by tributary streams (mainly by Obrówka). The current appearance ofall these landforms is the outcome ofprocesses acting since the stabilization of lake level in the Atlantic period. The following deposits of late Pleistocene age have been recognized in the Jasień lake trough: outwash sand and gravel, varved clays, calcareous gytja, lake marl with malacofauna, detrital gytja, and moss peat. The Holocene is represented by calcareous, calcareous-detrital and detrital gytja, variously decomposed peat and charcoal. The origin oflake sedimentary sequences was connected with lake level changes. In the late Vistulian the lake stands were considerably higher than today, whereas in the early Holocene the lake level dropped below the present one. Since the middle ofthe Atlantic period lake stands in the Jasień trough have fluctuated very little because the main lake is open at the downstream end, whereas dry periods have resulted in minor oscillations, up to 1 m. Recent drainage and channelization works have contributed to the lake level drop by a similar value.

Opis:

Within a small (2.5 x 2.5 km) test field, located in the eastern part of the Pomeranian Bay, the geological structure was sq investigated in detail using seismoacoustic profiling and coring. In the cores, mineral grain size and micro- and macrofauna were analysed. Basing on seismoacoustic records, three main seismostratigraphic units were distinguished. The lowest unit is built of sand and muddy sand. Higher up lies the unit of sandy mud, in some places - of clay. Fauna assemblages indicate cold climate conditions, and clearly point to an existence of lacustrine reservoir of oligotrophic character. Analysis of cores shows that sedimentation began in bog conditions. The lakes in the area existed till the Atlantic period, when due to sea transgression they became filled with sandy sediments. The third unit is built mainly of fine sand, locally medium sand, even with addition of gravel. Basing on the presence of marine fauna, this unit is classified as marine sand.

Przedmiotem badań są osady wypełniające zagłębienie wytopiskowe w Dzikowie, we wschodniej części Kotliny Toruńskiej, około 20 km na południowy wschód od Torunia. Analizowane wytopisko oraz sąsiadujące z nim Jezioro Dzikowskie usytuowane są na terasie Wisły. W celu odtworzenia ewolucji środowiska przyrodniczego tego obszaru przeprowadzono badania multidyscyplinarne. Badania geologiczne pozwoliły na określenie maksymalnej miąższości osadów biogenicznych w obrębie analizowanego wytopiska na około 10 m. Szczegółowe analizy paleoekologiczne (geochemiczne, palinologiczne i makroszczątków roślinnych) dostarczyły informacji o zmianach środowiska przyrodniczego w późnym glacjale i holocenie oraz umożliwiły wyodrębnienie kolejnych etapów rozwoju paleojeziora.
The object of current research is core of the bottom sediments of a kettle-hole at the Dzikowo site. Study area is located in the eastern part of the Torun Basin, in the area of the Vistula terrace, approximately 20 km southeast of Toruń. In order to reconstruct the environmental history of this region, multidisciplinary research was carried out. Geological research allowed to determine the maximum thickness of biogenic sediments to approximately 10 m. Detailed paleoecological analyses (palynological, plant macroremains, geochemical) provided information about environmental changes in the Late Glacial and the Holocene and helped to identify stages in the evolution of the paleolake basin.

Opis:

The Late Glacial and Early Holocene shallow lake history in Estonia is documented from the fresh water ostracod subfossil record. Three cores studied consist of Late Glacial and Holocoene sediments: gyttja, calcareous mud and peat, with ostracod subfossils being well preserved in the calcareous mud. 18 fresh water ostracod species were recorded in the cores: the most common species are Metacypris cordata, Limnocythere inopinata, Cyclocypris ovum, Cypridopsis vidua, and Candona candida. Changes in the ostracod succession of the lakes can be interpreted in the context of environmental changes that were not contemporaneous but were related to the evolution of particular water bodies. Darwinula stevensoni and Metacypris cordata do not appear together in the Late Glacial and Early Holocene lacustrine sediment records of Estonia. M. cordata appears as the water body evolves or by lowering of the water level. The appearance of Scottia pseudobrowniana in the sediments refers to the stage of an overgrown lacustrine system. M. cordata appeared in south eastern Estonia at the end of the Late Glacial (~12 800 cal. BP), when the calcareous mud started to form. The ea li est subfossil r cord of M. cordata from south wes ern Estonia is from the Early Holocene.

Opis:

The result of palaeobotanical studies of biogenic sediments from Pakosławice made it possible to establish the age of limnic and peat sediments and reconstruct past plant communities and development phases of the sedimentary/sedentary basin. The investigated mire originated from overgrowth of a shallow lake. The lake formed probably as a result of thermokarst processes (permafrost thawing). Accumulation of gyttja started in the Alleröd to continue in the Younger Dryas and early Holocene (Preboreal and Boreal). The sedentation of peat deposits probably took place in the middle and late Holocene.

Opis:

Core drilling of a hole Bysławek-2 consisted of gyttja and peat, lying on the mineral deposits (fluvioglacial sand). Lake sediments and peat were investigated by pollen analysis and radiocarbon dating (AMS). Sedimentation of mineral deposits took place into the subglacial channel, during the Main Stage of the Vistula Glaciation. The beginning of sedimentation in lake is dating at 13 340 š 70 years 14C BP, but pollen data suggest the Alleröd character of vegetation. According to pollen analysis gyttja and peat covered the period from the Alleröd to the Subboreal. The Alleröd forest dominated by Pinus sylvestris became more open in the Younger Dryas. The Holocene history of vegetation is characterized by relatively low content of Carpinus and Fagus in forest. Human impact was also generally low throughout the Holocene.

Opis:

The aim of this study was the reinterpretation of the published and unpublished Late-Pleistocene and Holocene pollen and diatom diagrams of deposits from the sedimentary basins of the Southern Baltic Sea and the correlation of the distinguished biostratigraphic units with lithological parameters, seismostratigraphic units. Chronostratigraphic subdivision of the Late Pleistocene and Holocene was also made. To facilitate the correlation and reinterpretation of the results of biostratigraphic (palynological and diatom) analyses, new unified and simplified diagrams were drawn using the POLPAL software. Such diagrams were constructed for all the sites under comparison, even for those of no numerical data. In such cases, the published diagrams were scanned and their percentage values were the basis for new diagrams. A review and reinterpretation of biostratigraphic data show an almost complete lack of palynological documentation and diatom diagrams for the Late Pleistocene period and poor documentation for the Early Holocene. Middle and Late Holocene Baltic muds have the best biostratigraphic documentation and radiocarbon dating, which greatly facilitates their location on the geological time scale. Among the Southern Baltic postglacial sediments three lithostratigraphic units were identified. They differ in their lithological features reflecting the conditions prevalent in the sedimentary basin during deposition. It should be noted that these units meet no formal criteria for distinguishing lithostratigraphic units. Similarly, within the Late Pleistocene and Holocene sediments of Southern Baltic deep-water basins, three main seismostratigraphic complexes have been identified. The integrated analysis of seismoacoustic profiles, lithological profiles of cores and reinterpretated biostratigraphic data allow a correlation of the bio-, litho- and seismostratigraphic units with chronostratigraphic units and Baltic evolutionary phases.

Opis:

The climate changes and related crucial environmental changes in the Late Glacial and Holocene in the Southern Baltic area can be investigated by mollusc and ostracod analyses. It is well known that accumulation of mineral and biogenic sediments in the Southern Baltic area began in the Late Glacial. The process took place in cold tundra lakes and mires. The presence of lake basins is confirmed by seismoacoustic investigations and the resulting 3D spatial model. Lacustrine sediments contain an assemblage of molluscs and ostracod fauna represented by freshwater species indicating cold climate, such as: Armiger crista f. cristatus, Gyraulus laevis, Lymnaea peregra, Pisidium casertanum, Pisidium casertanum f. ponderosa, Pisidium milium, Pisidium nitidum, Pisidium obtusale f. lapponicum, Valvata cristata, Pisidium conventus, Candona candida, Candona neglecta, Cytherissa lacustris, Darwinula stevensoni and Cypridopsis vidua. The accumulation in freshwater reservoirs was continued during the Early Holocene. Besides cold freshwater species, sediments of that age also contain freshwater species of molluscs and ostracods that required higher temperature: Bithynia tentaculata, Physa fontinalis, Pisidium amnicum, Candona compressa and Metacypris cordata. It indicates a climate warming in the Preboreal period. These lake sediments were partly destroyed and covered by marine sands during the Middle and Upper Holocene. Good indicators of changing from a freshwater to marine environment are the following marine species found in the sediments: Hydrobia ulvae, Hydrobia ventrosa, Cerastoderma glaucum, Mytilus edulis, Macoma balthica, Cyprideis torosa and Cytheromorpha fuscata.

Opis:

Geological mapping at a scale of 1:50 000 of the Lithuanian Maritime region has recently been focused on the delta of the Nemunas River and its surroundings. Pollen, diatom and mollusc analyses, lithological investigations, and radiocarbon and optically stimulated luminescence dates have enabled stratigraphic correlation of the Late Glacial and Holocene deposits which make up this delta. Palaeogeographical reconstructions of the southern part of the Lithuanian Maritime region during the maximum extent of the Baltic Ice Lake (~12 000-11 200 years BP), the Ancylus Lake (~8 700-8 500 years BP), the Litorina Sea (~6 100 years BP) and the Post-Litorina Sea (~4 000 years BP) have been made. A geological and geomorphological model of the Nemunas River Delta and its adjacent areas has been constructed. Our results suggest that that part of Nemunas River Delta in Lithuania is very young, having formed during the last 1 000-1 100 years.

Analizie malakologicznej poddano skorupki ślimaków i małży występujące w gytiach wapiennych i kredach jeziornych wypełniających torfowisko Gajlik na Pojezierzu Sejneńskim. W sześciu analizowanych próbkach stwierdzono występowanie 13 gatunków mięczaków wodnych. Obserwowane zmiany składu i struktury zespołu mięczaków uzupełnione wynikami analiz palinologicznych i radiometrycznych pozwoliły na rekonstrukcję ewolucji torfowiska Gajlik w okresie późnego glacjału i dolnego holocenu. Skorupki mięczaków występowały wyłącznie w osadach związanych z cieplejszym i okresami (interfaza oraz preborealna i borealna faza holocenu). Nie pojawiały się one natomiast w osadach zimnych okresów późnego glacjału.
Malacological analysis was conducted on snails and bivalve shells present in calcareous gytia and lacustrine chalk of the Gajlik mire in the Sejny Lake District. Thirteen species of water molluscs were identified within six analyzed samples. Changes observed in the structure and composition of molluscs, supplemented by palynological data, and the results of radiocarbon datings allowed for the reconstruction of the mire's evolution during Late Glacial and Early Holocene period. Molluscs' shells occurred solely in sediments associated with warmer periods (interphase and Preboreal-Boreal phases of Holocene). Additionally, they were not present in sediments associated with cold Late Glacial periods.

Opis:

Oxygen and carbon stable isotope records of two stalagmites from NW Romania provide a continuous climatic record between 14.8 and 5.6 ka BP. The chronology is established by 21 TIMS uranium series ages. Uncertain ties in the isotope chronology range between ±20 and ±100 yr. The δ18 O values are positively correlated with temperature, whereas δ13 C fluctuations suggest changes in soil CO2 production. Lateglacial deposition of both stalagmites started at ~14.8 ka BP. The delta 18 O records subsequently show a slow decline in temperatures until 12.6 ka BP. Three warmer periods with increased soil productivity occurred at 14.5-13.9 ka BP, 13.6-13.2 ka BP, and 12.9-12.6 ka BP. Lower delta 18 O and high δ13 C values between 12.6 and 11.4 (11.7) ka BP in dicate a cold and dry climate during the Younger Dryas (GS-1). During the Early Holocene, three short cold intervals are marked on the δ 18 O profiles at 11.0-10.6, 10.5-10.2 and 9.4-9.1 ka BP. For the remainder of the Holocene sequence, the δ18 O records show less variation between 9 and 7.8 ka BP and gradual warming from 7.6-5.6 ka BP. The speleothem records correlate with the Green land ice core records and with other proxies through out Europe and the North Atlantic region.

Opis:

Lacustrine organic sediments were sampled at Gronowo (Chełmno Plateau) and Piotrkowo (Dobrzyń Plateau) located within a widespread system of subglacial channels separated by the large Drwęca ice-marginal valley. They have been examined for their pollen, plant macro-remains and geochemistry, as well as radiocarbon-dated. The analyses have allowed reconstructing the evolution of the area and presenting an asynchronous appearance of two lakes. Before lake sedimentation, glaciolimnic sediments from the end of Plenivistulian, at the site of Piotrkowo, was dated. Lacustrine sedimentation started during the Allerød at Gronowo, and during the Preboreal at Piotrkowo. The different age of the two lakes is ascribed mainly to differences in the Late Glacial drainage conditions which directly affected the melting away of dead-ice blocks buried in the channels.

Opis:

This article discusses the formation and evolution of the coastal zone of the southern Baltic from the decay of the last Scandinavian ice-sheet, which took place some 14 ka BP. During the first 4 ka, the shores of the then southern Baltic basins were shaped under the dominant influence of considerable variations in water level and the young, post-glacial topography emerging from under the ice. Later, until the beginning of the Atlantic transgression, the shores were also unstable, because sea level changes resulting from periodic connections with the World Ocean followed one another in rapid succession. Since that transgression destroyed much of the former shoreline, its reconstruction is at best highly problematical, and in some places no longer possible. The maximum range of the Litorina Sea gave rise to a coastal zone that in many places is to this day quite conspicuous in the local topography and sediments. During the last 4 ka, the shoreline has changed relatively little, thus the present shoreline is largely redolent of the original one. In the coming 100 years or so, the abrasion of the cliffs along the southern Baltic shore will probably accelerate, as will the retrogradation of certain sections of the shoreline, with the result that the shoreline will be less of a straight line than it is at present. Land up to a height of 1 m above sea level will be inundated. The greatest changes in the lie of the shoreline are to be expected in the River Wisła (Vistula) delta and around the Zalew Szczeciński (Oderhaff, Szczecin Lagoon).

Opis:

Studies of infills of present-day peatland basins of the Łódź Region revealed the presence of lacustrine sediments underlying peats. They usually rest on mineral bottoms of basins, and their accumulation began in the Late Vistulian and continued in the Holocene. Out of 17 objects subjected to geological and palaeoecological examinations such arrangement was found in 8 of them. In the locality of the Żabieniec peatland 16.4 m of biogenic sediments was documented. The essential part of the profile contains detrital gyttja (at the bottom – detrital-clay gyttja, above – fine detrital gyttja). Within the Ner-Zawada peatland the thickness of biogenic sediments is 4.70 m and lake sediments are represented by clay- calcareous gyttja and calcareous gyttja. The thickness of biogenic sediments in the Ługi peatland reaches to 2.90 m. At this locality detrital- calcareous gyttja and detrital gyttja accumulated on the mineral substratum. In the Rąbień peatland basin the thickness of lacustrine sediments and peat reaches 6.2 m; on sandy bottom rest detrital-clay gyttja and detrital gyttja. In the Silne Błoto-Witów peatland only the 3.5 m long profile of the so- called “west island” contains lacustrine deposits covered by herbaceous peat. In the bottoms of a few other peatlands of the region, biogenic lake deposits were found, but their thickness is small (such as Korzeń, Bęczkowice, Parchliny). Therefore it may be assumed that some peatlands of the Łódź Region are of limnic origin. The presented examples of lake sediment series in the basins of contemporary peatlands in the Łódź Region allow to conclude that during the last fifteen thousand years, lakes occurred in this area, not only in numerous oxbow basins, but also in plateau depressions and aeolian landforms. Lake basins were more frequent during the late Vistulian, and survived in the Holocene until the Subboreal period. All water bodies of wetlands of the Łódź Region, except for oxbows, which are observed today, are of an anthropogenic origin.
Analiza wypełnień mis współczesnych torfowisk regionu łódzkiego wykazała pod torfami obecność osadów jeziornych. Zalegają one zwykle na mineralnym dnie mis, a ich akumulacja rozpoczęła się w późnym vistulianie i trwała jeszcze w holocenie. Spośród 17 obiektów poddanych szczegółowym badaniom geologicznym i paleoekologicznym taki układ osadów stwierdzono w ośmiu z nich. W misie torfowiska Żabieniec udokumentowano 16,4 m osadów biogenicznych, a zasadniczą część profilu stanowi gytia detrytusowa (w dolnej części detrytusowo-ilasta, a powyżej gytia drobnodetrytusowa i grubodetrytusowa). W obrębie torfowiska Ner-Zawada miąższość osadów biogenicznych wynosi 4,70 m, a osady jeziorne reprezentują: gytia ilasto-wapienna i gytia wapienna. Miąższość osadów biogenicznych w obrębie torfowiska Ługi sięga 2,90 m, na mineralnym podłożu zalega gytia detry- tusowo-wapienna i gytia detrytusowa. W torfowisku Rąbień miąższość torfu i podścielających go osadów jeziornych sięga 6,2 m, na piaszczystym podłożu zalegają: gytia detrytusowo-ilasta i gytia detrytusowa. Torfowisko Silne Błoto-Witów dokumentuje jedynie profil z tzw. wyspy zachodniej o miąższości 3,5 m prezentujący głównie osady jeziorne, przykryte przez torf zielny. W podłożu torfów kilku innych torfowisk regionu stwierdzono biogeniczne utwory jeziorne, ale ich miąższość jest niewielka (m.in.: Korzeń, Bęczkowice, Parchliny). Uznać więc należy, że część torfowisk regionu łódzkiego ma pochodzenie limnogeniczne. Zaprezentowane przykłady serii osadów jeziornych w misach współczesnych torfowisk regionu łódzkiego pozwalają stwierdzić, że w trakcie ostatnich 15 tysięcy lat jeziora występowały na tym obszarze nie tylko w licznych starorzeczach, ale także w obniżeniach wysoczyznowych i wśród form eolicznych. Zbiorniki jeziorne funkcjonowały liczniej w okresie późnego vistulianu, a w holocenie przetrwały aż do okresu subborealnego. Wszystkie zbiorniki wodne na obszarach mokradeł regionu łódzkiego, poza starorzeczami, obserwowane współcześnie, mają charakter antropogeniczny.

Opis:

In the Serteyka River valley in western Russia, eight accumulative fans formed at the mouths of ravines were examined geologi-cally and geomorphologically. The test samples were collected from individual geological drillings made with a manual probe, as well as from excavations in the central and distal zones of the fans. Using the Gradistat program, sedimentological indicators were calculated, i.e. mean grain diameter (MZ), standard deviation (sorting – σI), skewness (SkI) and kurtosis (KG),and then particle-size distribution frequency curves, cumulative curves and a Passega C/M diagram were drawn. It has been documented that the grain size of the fan sediments depends on the characteristics of the source material. Analysis of sedimentological indicators (mean grain diameter, sorting, skewness, kurtosis) showed the studied fans deposits to have a large variability of erosion and accumulation conditions. For the deposits of younger fans, the 2nd system of the MZ-versus-σI relationship after Mycielska-Dowgiałło (1995) was distinguished, while for the older, the 2nd, 3rd and 4th systems were recognised. The main process of grain transport within these forms was saltation. The ravines on the eastern slope of the Serteyka valley were most likely created in the periglacial period, while the gullies on the western side of the valley developed in the early modern period.

Opis:

Veg e ta tion changes in the Lower San Val ley near Jaros³aw are re con structed from the Youn ger Dryas to the pres ent time on the ba sis of palynological anal y sis of the peat core. The pol len pro file came from a an old riverbed and was sup ple mented by ra dio car bon datings. The Youn ger Dryas and early Preboreal veg e ta tion was char ac ter ised by a high pro por tion of for est com mu ni ties with pine (Pinus sylvestris and P. cembra) and birch (Betula), while patches of open area were dom i nated by the steppe with Ar te mi sia. Cli ma tic ame lio ra tion dur ing the Preboreal chronozone led to the rapid spread of elm (Ulmus), which was prob a bly a dom i nant taxon on the low est ter races of the val ley. Terrestrialization of the wa ter body ex ist ing in the palaeomeaner and the sub se quent be gin ning of peat ac cu mu la tion caused a de - te ri o ra tion in pol len pres er va tion. Hence, the in ter pre ta tion of the pro file sec tion span ning the pe riod be tween the Bo - real and Subatlantic chronozones was se ri ously dis turbed due to se lec tive cor ro sion and the overrepresentation of Pinus sylvestris type and Filicales monolete sporomorphs. Be tween ca. 336 and 1152 AD fluc tu a tions in wood land cover were re corded. Im por tant com po nents in those for ests, de spite the dom i na tion of Pinus sylvestris, were Quercus, Carpinus betulus, Fagus sylvatica and Abies alba. The first pol len grains of ce re als (Cerealia type) were found be fore ca. 1605–1414 BC and may be at trib uted to the ag ri cul tural ac tiv ity of the Neo lithic and/or early Bronze tribes. Pe ri - ods of strong de for es ta tion caused by hu mans were prob a bly re lated to the time when the Tarnobrzeska Group of the Lusatian Cul ture and the Przeworska Cul ture were ac tive. The first groups of Slavs did not sig nif i cantly in flu ence the en vi ron ment, but the sub se quent de vel op ment of those groups led to more vis i ble de for es ta tion, which was trig gered af ter the es tab lish ment of Jaros³aw in the 11th cen tury AD.

Opis:

Krzywą względnych zmian poziomu morza skonstruowano na podstawie 314 dat radiowęglowych osadów pochodzących z różnych środowisk lądowych i morskich. Próbki do datowań pobrano z 163 stanowisk zlokalizowanych na obszarze polskiej części południowego Bałtyku i przyległej strefy brzegowej. Przy konstruowaniu krzywej wykorzystano również relikty różnych form związanych z rozwojem strefy brzegowej oraz zasięgi powierzchni erozyjnych, zlokalizowane na profilach sejsmoakustycznych. W późnym plejstocenie i wczesnym holocenie, między 13,0 i 8,5 tys. lat BP, poziom wody trzykrotnie wzrastał i opadał, a zakres wahań dochodził do 25-27 m. Poziom wody obniżał się w skrajnych przypadkach w tempie do ok. 100-300 mm/rok, a tempo wzrostu dochodziło do ok. 35-45 mm/rok. W późnym boreale, ok. 8,5 tys. lat BP, Bałtyk uzyskał stałe połączenie z oceanem na poziomie niższym od obecnego o ok. 28 m. Do początku okresu atlantyckiego poziom morza wzrósł do ok. 21 m poniżej współczesnego poziomu morza (p.p.m.). W okresie 8,0-7,0 tys. lat BP poziom morza wzrósł do 10 m p.p.m., w średnim tempie ok. 10 mm/rok. Do końca okresu atlantyckiego poziom morza wzrósł do 2,5 m p.p.m., a tempo wzrostu zmalało do ok. 2,5 mm/rok. W pierwszym tysiącleciu okresu subborealnego poziom wody wzrósł do ok. 1,1-1,3 m, a do końca tego okresu do ok. 0,6-0,7 m niższego niż współczesny. W okresie subatlantyckim średni poziom morza zmienił się już nieznacznie. Przebudowa glaciizostatyczna rozpoczęła się ok. 17,5 tys. lat BP i zakończyła ok. 9,2-9,0 tys. lat BP. Całkowity zakres podniesienia (total uplift) w tym okresie wyniósł ok. 120 m. Maksimum prędkości ruchów wznoszących, dochodzące od ok. 45 mm/rok, wystąpiło w okresie ok. 12,4-12,2 tys. lat BP. W okresie od ok. 9,0 do ok. 7,0 tys. lat BP przez obszar południowego Bałtyku migrowało nabrzmienie brzeżne, a w okresie od ok. 7,0 do ok. 4,0 tys. lat BP wystąpiły ruchy obniżajace. Od ok. 4,0 tys. lat BP położenie skorupy ziemskiej wróciło do stanu równowagi. Linia brzegowa południowego Bałtyku w późnym plejstocenie i wczesnym holocenie kilkukrotnie uległa szybkim i znacznym przemieszczeniom. Zmieniła położenie w tempie od kilkudziesięciu metrów do kilku kilometrów rocznie. Procesy te rozgrywały się na powierzchni dna morskiego położonej obecnie na głębokości od ok. 55 do 25 m p.p.m. i w odległości 30-60 km od dzisiejszego wybrzeża. W środkowym holocenie linia brzegowa przemieściła się ku południowi od ok. 60 km w Zatoce Pomorskiej do ok. 5 km w Zatoce Gdańskiej. Położenie linii brzegowej zbliżyło się do współczesnego w końcu okresu atlantyckiego. W późnym holocenie dominowały procesy wyrównywania wybrzeży, a linia brzegowa stopniowo zbliżała się do obecnego położenia.

Opis:

Na podstawie szczegółowego kartowania geomorfologicznego i geologicznego przedstawiono uwagi o rozwoju rzeźby doliny dolnej Wisły od schyłku ostatniego glacjału do czasów dzisiejszych. Na podstawie badań sedymentologicznych osadów wysnuto tezę o silnym uwarunkowaniu ich depozycji od starszych założeń doliny widocznych już w sposobie depozycji osadów glacjolimnicznych ze schyłku ostatniego zlodowacenia. Szczególną uwagę zwrócono na rolę brył martwego lodu warunkujących rozwój tarasów fluwioglacjalnych i fluwialnych. Omówiono rozwój sedymentologiczny równiny zalewowej Wisły, będącej morfologicznym efektem coraz silniejszego wpływu człowieka na środowisko naturalne. Wskazano na dużą stabilność koryta Wisły i pewne cechy osadów mogące świadczyć o inicjalnym stadium kształtowania się rzeki typu zbliżonego do anastomozującego.

Opis:

The aim of the article is to show the significance of the morphogenetic processes which took place during the reactivation of cold stages during the Late Vistulian in the Łódź Region, in the light of the latest stratigraphical and paleaoenvironmental approach. The processes were activated in slope, fluvial and aeolian environments and operated under conditions of climatic unstability. The transitional nature of this period caused that processes characteristic of the periglacial environment, with the permafrost presence, overlapped with the moderate conditions. The cold periods were potentially favorable for morphogenetic activity, although their records are in the Łódź Region not as common as the effects of the processes that took place during earlier periods of the Vistulian.
Celem artykułu jest wykazanie znaczenia rzeźbotwórczej roli okresów cyklicznych powrotów zimna w późnym vistulianie w ewolucji regionu łódzkiego w świetle najnowszych interpretacji stratygraficznych i środowiskowych. Procesy rzeźbotwórcze późnego vistulianu były uruchamiane w środowiskach: stokowym, rzecznym i eolicznym działały w specyficznych warunkach niestabilności klimatycznej. Przejściowość tego okresu powodowała, że zazębiały się procesy charakterystyczne dla środowiska peryglacjalnego, przy udziale zmarzliny oraz dla środowiska umiarkowanego. Zimne fazy potencjalnie sprzyjały aktywności morfogenetycznej, chociaż ich świadectwa nie są w regionie łódzkim tak powszechne jak efekty procesów, które miały miejsce podczas wcześniejszych okresów vistuliańskich.

Opis:

The Shelter above the Zegar Cave (Shelter No 388) (N 50°25’41” E 19°40’27”) is located in the Zegarowe Rocks ridge in the Ryczów Upland (southern part of the Czêstochowa Upland), municipalityWolbrom, district Olkusz. In 2009, Mrs. Jadwiga and Mr. Lucjan Wodarz found an archeological flint artifact in a type of leaf point at the slope below the Shelter. This finding allowed suspecting the presence of Palaeolithic cultural layers inside or near the Shelter. The authors’aim was to recognize the geological context of the Palaeolithic settlement of the Shelter above the Zegar Cave and its neighborhood, and in further perspective of the entire southern part of the Ryczów Upland micro-region. Four layers were discovered in the Shelter during field works (downward): I – humic silty loam, Holocene; II – loess altered by secondary soil processes during the Holocene; III – unaltered loess, dated to MOIS 2; IV – silty cave loam with limestone rubble, dated to MOIS 3. The chronostratigraphy is based on lithostratigraphy and confirmed by radiocarbon and thermoluminescence dating. An archaeological cultural level occurs in layer IV, most probably related to the shift from the Middle to Upper Palaeolithic. The sequence of cave sediments may be well correlated with numerous profiles of cave sites from the Kraków-Czêstochowa Upland.

Opis:

Fens have been forming in the river valleys of central Poland since the Bølling and went through a transformation from fully aquatic to semiterrestrial habitats during the Younger Dryas/Holocene transition. This drove plant and invertebrate communities and left a distinct pattern in chemical sediment composition, which is why river valley peatlands are sensitive palaeo-archives of climatic, hydrological and edaphic changes. Here we reconstruct the Late Weichselian history of the Bęczkowice fen in the upper Luciąża River valley using geochemical, pollen, Cladocera and Chironomidae proxies. Pollen-based age estimation indicates that the analysed peat sequence dates from the Bølling to Early Holocene. The layers 190-170 cm and 125-105 cm of the studied core were reworked by fluvial processes. Chironomidae and Cladocera communities indicate mostly limnetic conditions during the Allerød and early Younger Dryas. Peatland pools were supplied mostly by Luciąża River floods, but also by groundwater. Since the onset of the Holocene, the water level has dropped, eliminating aquatic midges and water fleas, and supporting taxa typical of astatic waters and wet soil.
