    Opis:
    Palynological studies have been done to compare the Upper Ordovician strata in various geological units of northern and central Poland (epi-Caledonian Platform, East European Platform, Małopolska Block and Holy Cross Mountains–Łysogóry Fold Zone and Kielce Fold Zone). Two distinct palynological assemblages have been distinguished in the studied material: the Caradoc assemblage I and the Ashgill assemblage II (with two sub-assemblages IIa and IIb), thus demonstrating usefulness of the Upper Ordovician palynomorphs for biostrati- graphy. Thermal maturity of organic matter was studied using the TAI method. The palynological analysis, palynostratigraphy, and estimates of thermal maturity were done with the aim at palynological characterization of three ancient units: the Avalonia, Baltica and the Małopolska Block, all now participating in structures of the present-day geological units of northern and central Poland.

    Opis:
    One of criteria suggesting impact origin may be recognition of extraterrestrial matter inside or around suspected cavities. In case of Morasko some dating results throw doubt on link between craters and meteorites. Conclusion of some past research papers was that cavities were formed about 5 ka BP (e.g. palynological investigation, luminescence dating), while more or less facts testify fall in the Middle Ages (e.g. “young” charcoal pieces in crust of meteorites or shrapnel stuck in the roots of old tree). In this paper we perform comprehensive analysis of each result and check if there exists alternative explanation. During past palynological investigation, there were examined two craters. It was concluded that beginning of accumulation of sediments in smaller cavity started 5500–5000 BP. However, pollen spectrum for largest basin was different suggesting younger age. The problem is that according to bathymetric maps, samples could be collected from inner uplift (similar feature was observed inside Porzadzie and Jaszczulty, unconfirmed impact structures yet). If we compare profiles from craters with recent research (palynological study supported by radiocarbon dating) on sediments in Lake Strzeszynskie (6 km SW from Morasko) pollen spectrum seems to be similar more to results dated to <1000 BP. Especially percentage of non-arboreal pollen for both examined Morasko craters is much higher (5 times greater than it was for layer dated to 5 ka BP in Lake Strzeszynskie). Possibility of short disturbance (related to impact) cannot be excluded, but in such case any time of event should be taken into account. For small lakes (like those filling the craters) also local conditions could play important role. Analysis of luminescence dating may also discuss past conclusions. OSL method applied for samples taken from the thin layer of sand in the bottom of largest structure (under 3,9 m of organic sediments filling the crater) suggested age 5–10 ka BP for 24 aliquots. Same number of samples (24) revealed age 0–5 ka BP (13 samples with age <3 ka BP including several younger than 1 ka BP). Older dates can be explained by partial or even no zeroing, but last contact with light (zeroing signal) of sand grains (excavated from depth of almost 4 meters under organic matter) seems that might occur only during (or shortly after) the impact. It is difficult to find convincing arguments, which can undermine initial radiocarbon dating giving age <1 ka BP for 7 of 9 samples taken from the bottom layer of organic sediments from three Morasko craters. Same issue may exist with small charcoal pieces with age <2 ka BP (and several dated to ~700 BP) discovered deep in sinter-weathering crust of meteorites. Study of charcoal particles excluded their origin during post-sedimentary processes (like forest fire) unless meteorite fragments were laying directly on the surface for period between impact and wildfire (surviving whole time inhospitable climate conditions). There are two other possible explanations of charcoals. Either they were present at location as a result of past forest fire or they were produced during impact. However, similar small charcoal pieces were discovered around many craters (Kaali, Ilumetsa, Campo del Cielo, Whitecourt) and they were successfully used to estimate maximum age of those structures. During second stage of 14C dating the age obtained from three samples (taken few centimeters above the mineral bottom) was estimated ~5 ka BP. Looking for answer why these results are so different from previous once there may be mentioned at least two options. Lake sediments is difficult matter for radiocarbon dating and results may be hundreds or even thousands years older than real age. Second explanation may be that older matter (remnant of trees, paleosoil etc.), distributed around craters during impact, could be displaced by wind, rain, erosion and trapped in the bottom of cavities. The argument, which may be also against hypothesis of impact ~5 ka BP is meteorite shrapnel stuck in the roots of old tree. Result of expertise showed, that there exists mechanical damage in the wood and the only possible explanation is that meteorite has hit living tree. Maximum age, that this type of wood may preserve (inside building) is 1,8 ka while in natural environment not more than 500 years. Anyway some further examinations should be performed. The age obtained during AMS 14C dating of 2 samples from thin layer of paleosoil, discovered under overturned flap around largest Morasko crater, was ~5 ka BP. Observation that preserved layer of paleosoil is approximately 3 times thinner than thickness of modern soil may lead to conclusion that during impact top (younger) layer of organic sediments was removed and only older part “survived” in few locations close to the rim. The conclusion of the research was that dating provides maximum age of the impact (which does not exclude much younger impact <1 ka BP) so could be considered as right explanation of past discrepancies.

    Opis:
    Na obszarze rynny jeziora Jasień zlokalizowano cztery stanowiska, dla których wykonano analizę palinologiczną i analizę szczątków Cladocera. Celem badań było odtworzenie przemian środowiska przyrodniczego na tym terenie. Rdzenie, z których pobrano próby do analiz, składały się głównie z osadów typu gytia i torf. Próbki do analiz wykonywano według standardowych procedur. Do obróbki danych liczbowych wykorzystywano program POLPAL. Otrzymane wyniki palinologiczne umożliwiły odtworzenie historii roślinności badanego terenu począwszy od okresu borealnego, a analiza szczątków Cladocera dostarczyła informacji o fazach rozwoju części zbiornika jeziornego Obrowo Duże.
    In order to reconstruct the environmental history of the Jasień Lake trough, pollen analysis and an analysis of Cladocera remains have been simultaneously carried out. Sediments for pollen research have been collected in the bay section of the Jasień Lake and in the Obrowo Małe peat bog. Cladocera remains have been sampled in two sites within a peat bog adjacent to the Obrowe Duże Lake. Preparation of samples for both analyses followed standard procedures. Numerical data have been elaborated using the POLPAL software. The results of the palynological study have allowed to decipher vegetation history since the Boreal period. The peat bog of Obrowo Małe began to form at the onset of the Atlantic period. Cladocera remains yielded information about phases of water body evolution in the part of the Obrowo Duże Lake, which subject to silting transformed into a low-level valley bog, and then into a transitional peat bog. Pollen and Cladocera analyses have been carried out on material collected at dissimilar sites, which practically excludes the possibility of correlation of results and allowed one only to reconstruct the major hydrological changes, common for the entire region. In the latest Holocene, in the Jasień Lake trough a trend towards water level decrease is observed due to both climatic and human impact. Further changes included the rise of trophic level in the lake and vegetation succession onto the shallower parts of the lake.

    Opis:
    W rejonie Nowego Tomyśla, na terenie zachodniej Wielkopolski, w otworach wiertniczych z Woli Jabłońskiej, Cichej Góry i Lasek stwierdzono osady rzeczne, określone jako formacja z Lasek. Wypełniają one doliny kopalne do głębokości 40−50 m, leżą na glinach zlodowacenia odry (typ Dopiewiec) i są przykryte trzema glinami zlodowacenia warty (typy: Karolewo, Kopaszewko i Ujście). Utwory rzeczne powstawały w środowisku peryglacjalnym (ekstraglacjalnym), o silnych procesach eolicznych. Osady formacji z Lasek, z okolic Nowego Tomyśla reprezentują prawdopodobnie fragment wypełnienia doliny kopalnej Prawarty/ Praprosny. W jej obrębie (profil Wola Jabłońska) stwierdzono osady organiczne pochodzenia jeziornego. Wyniki analizy palinologicznej wskazują na niepełną interglacjalną sukcesję pyłkową, obejmującą początkowy okres chłodny oraz optimum charakteryzujące się klimatem umiarkowanym i wilgotnym. Spektra pyłkowe z najcieplejszego odcinka profilu odzwierciedlają panowanie lasu sosnowo-świerkowego i zarośli olszynowych z domieszką roślin o większych wymaganiach termicznych, wśród których na szczególną uwagę zasługują ziarna pyłku i owoce należące do rośliny wodnej Trapa natans dotychczas stwierdzonej jedynie w osadach interglacjalnych. Podobny obraz zbiorowisk leśnych wykazuje profil na terenie Bełchatowa, który był datowany na interstadiał pilicy, a obecnie jest określany jako interglacjał lubelski. Odniesienie profilu z Woli Jabłońskiej do tego interglacjału nie ma pewnego uzasadnienia, ponieważ pozycja palinostratygraficzna i geologiczna uzyskanej sukcesji roślinności jest trudna do ustalenia.
    Fluvial sediments has been recorded in three boreholes near Nowy Tomyśl, western Poland (Wola Jabłońska, Cicha Góra, Laski). Wola Jabłońska profile contains organic and fluvial deposits. This series has been formally named the Laski Formation. The fluvial sediments fill deep palaeovalley (40–50 m). They overlie the Dopiewiec till (Early Saalian, Odranian) and are overlain by three late Saalian (Wartanian) tills: Karolewo, Kopaszewko and Ujście. The fluvial suite was deposited mainly in periglacial environment, with strongly developed aeolian processes in the valley. However, during the optimal part of the period the aeolian processe almost completely ceased. The uppermost part of the suite exhibit suggests that deposition took place at the front of an advancing ice-sheet (high aggradation rate, admixtures of glacial derived material). The Laski Formation deposits may represent a fragment of pre-Warta/ Prosna palaeovalley. The organic sediments from Wola Jabłońska represent the climatic optimum of the interglacial and the early stages of the succeeding cold period. The picture of vegetation is characterized by spruce-pine forest with common alder and small admixtures of deciduous trees at the climatic optimum. Among local aquatic vegetation, the most characteristic is the occurrence of pollen and seeds of Trapa natans; a species hither noticed only in the interglacial successions. Climatic conditions that time were temperate and humid. The flora of Wola Jabłońska have features that resemble the forest communities at Bełchatów profiles in central Poland which was determined as the Pilica Interstadial, currently named as the Lublinian Interglacial. However, the profile from Wola Jabłońska cannot be unequivocally ascribed to this interglacial period, since the palynostratigraphic and geologic position of its vegetation succession is difficult to determine.

    Opis:
    Palaeobotanical, mainly palynological, investigations, carried out in the Tatra Mts. and Podhale region made it possible to date organic sediments as well as to trace history of migration routes of several plant taxa, mainly trees. The results of pollen analyses allowed for the reconstruction of formation of individual vegetation belts in the Tatra Mts. The development of human settlements was traced on the basis of pollen analyses of the Podhale peat bogs. The decline of the last glaciations (Weichselian) and the Holocene are the best studied periods in this area, as far as palaeobotany is concerned. In the present overview most of earlier studies were taken into consideration.

    Opis:
    The sedimentological, geochemical and diatomological research into the core taken from the fossil lake located in the glacial channel of Samica river prove the increasing anthropogenization of the landscape in the microregion surrounding the settlement in Bruszczewo. Anthropogenic indices of the Early Bronze Period in the palynological research include: high decline in the percentage of tree pollens caused by deforestation, indicators of grazing animals and farming as well as noticeable eutrophication of the lake (fungal spores and algae thriving on dung, droppings and excrement). In the sedimentological research, cultural layers correspond with accelerated mineral sedimentation in the basin (mediumand fine-grained sands). Each time it is preceded with organic sedimentation (from humus levels). Above results might signify the initiation of erosion-denudation processes in the catchment, settled and economically exploited by individual cultural groups. Results of the anthropogenic activity are visible also in the geochemical composition of the deposits. Cultural layers are marked with increased percentage of heavy metals, while the Cu : Pb : Zn ratios suggest their anthropogenic character. Additionally, the increase in phosphorus percentage confirms eutrophication of the basin in the settlement periods, that is in the Early and Late Bronze, and Early and Roman Iron Ages.

    In this paper the evolution of paleogeographic models of the middle part of the Chodelka valley near Chodlik is presented. In the relief of the bottom valley clear traces of palaeochannels are present. Lithological and palynological analysis helped distinguish two phases in the development of this river. The first phase started in Late Vistulian, and continued in the early Holocene. At that time Chodelka was an anastomosing river. But later it changed its channel pattern to the meandering one. Nowadays the Chodelka river cannot develop naturally, because its trough is largely limited by flood bank.

    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:
    We reconstruct palaeoenvironmental changes since the Late Holocene in the Orava-Nowy Targ Basin, with an emphasis on anthropogenic influence (Walker et al., 2018). This reconstruction employs multiproxy analyses of the Otrębowskie Brzegi poor fen. We combined radiocarbon and 210Pb dating with elemental geochemistry, stable lead isotopes, and palaeobotanical analyses. The core we investigated covers a period from 4200 ± 100 BC to the present, with a peat accumulation rate varying between 0.001 and 0.243 cm y-1. Heavy metal concentrations, Pb isotopic ratios, and a palynological analysis revealed a significant impact of human activities in the past. The highest concentration and accumulation rate of Pb, were found around 1950 AD. The 206Pb/207Pb quotient ranged between 1.168 and 1.223, with average value around 1.198. Most of the interpretation was based on Pb and its stable isotopes; however, other elements were also important indicators of natural and anthropogenic environmental changes. Our results revealed similarities between the geochemical composition of the peatland studied and other peatlands from the Orava-Nowy Targ Basin.

    Opis:
    On the basis of lake sediments studies (palynological, subfossil Ostracoda and geochemical analyses) the main stages of the palaeoenvironmental changes were obtained. Lake Syczyńskie is situated in the Pagóry Chełmskie region. Defined changes of plants, Ostracoda and variability of the main characteristics sediments (content of organic matter and calcium carbonate) showed high compatibility with widely recognised stages of climate change during the Late Glacial and the holocene. The detailed analysis allowed indicating the main phases of biological development of the lake based on the processes of eutrophication, hydrological changes in the lake catchment and temperature conditions. Determined Ostracoda species in the sediments of Lake Syczyńskie, among other Cytherissa lacustris, Metacypris cordata and Fabaeformiscandona protzi is the basis of concluding about significant changes in the functioning of the lake occurring under the influence of climate changes.
    W oparciu o wyniki badań osadów jeziornych (analiz palinologicznych, składu gatunkowego subfosylnych zespołów Ostracoda i podstawowych analiz geochemicznych) określono główne etapy zmian paleośrodowiskowych w rejonie Jeziora Syczyńskiego, położonego w obszarze Pagórów Chełmskich. Określone w badaniach etapy zmian szaty roślinnej w otoczeniu jeziora, zmiany składu gatunkowego subfosylnych zespołów małżoraczków (Ostracoda) w ujęciu jakościowym oraz zmienność podstawowych cech akumulowanych osadów (zawartość materii organicznej i węglanu wapnia) wykazały dużą zgodność z powszechnie wyróżnianymi etapami zmian klimatycznych późnego glacjału i holocenu. Wykonane analizy pozwoliły na wskazanie najważniejszych etapów biologicznego rozwoju jezior z uwzględnieniem procesów eutrofizacji, hydrologicznych zmian w zlewni jeziornej i warunków termicznych. Zidentyfikowane w osadach Jeziora Syczyńskiego gatunki małżoraczków, między innymi Cytherissa lacustris, Metacypris cordata i Fabaeformiscandona protzi dały podstawę wnioskowania o zasadniczych zmianach w funkcjonowaniu zbiornika wodnego zachodzących pod wpływem zmian klimatycznych.
