Opis:
The paper presents the results of an analysis of ichthyofaunal variability throughout the section of the Menilite-Krosno Series (MKS) in the Outer Carpathians of Poland. The studied tanathocoenoses were formed at the bottom of a more than 2,000 m deep northern basin of the Tethys, being largely represented by the continental rise and bottoms of its narrow furrows, and - to a lesser degree - the continental slope and slopes of a submarine high. Lateral variability of statististically representative assemblages of tanathocoenoses hosted in thin, isochro- nous horizons is interpreted as a result of both local changes of ichthyocoenoses and the influence of post-mortem relocation of fishes that mainly dwelled the shelf and upper continental slope. Vertical variability, in turn, is considered as a resulting from changeable conditions of the ecological environment, the input and outflow of taxa whose evolution proceeded in the Indo-Pacific area, and the species extinction. Changeability of ichthyofauna within a ca. 16-m.y.-long interval made it possible to document and formally describe 9 zones and 4 subzones of ichthyofauna of ecostratigraphic character. These zones comprise index, representative and accompanying taxa that belong to different ecological groups. Conceptual models of the origin of ichthyofaunal assemblages of individual zones are presented. It is suggested that the origin of assemblage differentiation resulted from the appearance and disappearance of the oxygen minimum zone in the water column, global and local sea level changes, topography of the basin bottom, as well as final basin infilling by sediments of submarine fans. The described and preserved collection of fossil Carpathian fishes, housed at the Department of Palaeozoology of the University of Wrocław, requires further specialized palaeontological studies in order to reconstruct a more complete composition of the Oligocene-Early Miocene ichthyofauna.

Opis:
The Łanięta site with fossil lake deposits is situated just in front of the maximum extent of Vistulian Glaciation ice. Palynological analysis shows that lake accumulation lasted through the Eemian Interglacial and almost the whole Early Vistulian, the longest record of this time interval in this part of Poland. Two warm interstadial-rank oscillations (Brörup and Odderade) and two stadials have been distinguished during the Early Vistulian. The older of these is correlated with the Herning Stadial while younger one equates with the Rederstal Stadial of the German succession.

Opis:
The Upper Silesia -Dąbrowa Basin is one of the highest industrially transformed regions in Europe. However, places of geotouristic value are still preserved and should be protected. One of them is the abandoned "Kamionka" quarry and nearby St. Dorotahill, knownas "local Olympus" with historical monuments, located in the Grodziec district of Będzin. The profile of Triassic limestones, dolomitized limestones and marly dolomites belong to so called Gogolin Beds and represent the sedimentation typical of sea transgression with numerous changes in water energy, up to stormy sedimentation, imprinted in rock textures and sedimentary structures. Both proximal and distal tempestites are found here. Local bioturbations are indicative for breaks in storm activity and low-energy sedimentation. In general, the carbonate sediments of Grodziec district were formed in shallow basin, on the carbonate ramp, influenced by storms and/or bottom currents. The link between the history of that area, geomorphology and geological features makes that area of special importance for geotourism.
Basen śląsko-dąbrowski należy do najbardziej uprzemysłowionych, a przez to silnie zmienionych w wyniku działalności człowieka, rejonów Europy. Miejsca o wartości geoturystycznej z racji swej rzadkości powinny być pod specjalną ochroną. Jednym z takich miejsc jest nieczynny kamieniołom „Kamionka" usytuowany blisko wzgórza św. Doroty, znanego także jako „Olimp zagłębiowski ", usytuowane w dzielnicy Będzina o nazwie Grodziec. Odsłaniający się w kamieniołomie profil triasowych wapieni, częściowo zdolomityzowanych i marglistych należy do tak zwanych warstw gogolińskich i reprezentuje cechy sedymentacyjne typowe dla transgresji morskiej. W osadach znaleźć można zapis teksturalny i strukturalny wielokrotnych zmian energii wód aż do sedymentacji sztormowej, z charakterystycznymi osadami tempestytów proksymalnych i dystalnych. Lokalnie obserwowane bioturbacje wskazują na przerwy w aktywności sztormowej i sedymentacji niskoenergetycznej. Sekwencje osadowe, odsłaniające się w Grodźcu, powstawały w płytkim basenie sedymentacyjnym, na rampie węglanowej, noszą cechy zarówno osadów sztormowych, jak i prądów dennych. Obszar Kamionki - wzgórza św. Doroty jest przykładem związków między budową geologiczna, geomorfologią oraz historią regionu i jest przez to obszarem o dużym znaczeniu geoturystycznym.

Opis:
Measurements of activity concentrations and speciation of 137Cs in bottom sediments of the Curonian Lagoon were carried out in samples collected in 1999-2003. In addition, the sorption-desorption processes of caesium in disturbed bottom sediments of fresh and sea water systems were investigated in long-term experiments (up to 375 days) in order to better understand the caesium behaviour during the Baltic Sea water flooding events to the Curonian Lagoon. The modified Tessier method was used to study caesium associations with geochemical phases of bottom sediments. The effect of carbonate coatings of bottom sediments on the Cs sorption-desorption process was observed. The comparative analyses of 137Cs solid phase speciation in bottom sediments after 241 and 375 days of the sorption experiment with that of the 137Cs speciation, determined in the same sediment sample before the sorption experiment, indicated that after 375 days of sorption the equilibrium was not reached, however, the Cs distribution in geochemical phases was found to be close to equilibrium. The desorption experiments evidenced the release of caesium into solution from regular exchange complex and transfer from other phases to the frayed edge sites on the layered clay minerals with its further fixation in the crystal lattice. The remobilization of "fixed" caesium was not observed, on the contrary, the redistribution of caesium with its subsequent fixation in clay minerals was observed, and on a time scale its fixation kinetics was comparable with the sorption experiment. This study showed that flooding events of sea water contaminated with caesium can cause a significant accumulation of caesium in the bottom sediments of the Curonian Lagoon and result in the redistribution of 137Cs activity concentration in the bottom sediments from one area to another.

Opis:
The article presents the results of studies upon metals (Pb, Zn, Cr, Ni, Cu, Co) in bottom sediments and in various parts of the aquatic plants taken from the Bug river (Poland). The metal contents in the examined environmental elements were determined by AAS technique. The aim of this study was to evaluate the content of metals in bottom sediments and macrophytes (root, stem, leaf) occurring in the Bug river. It was hypothesized that the heavy metal content in plant tissues reflects the amount of metals in sediments. It has been shown that the average metal distribution in the examined plants present in the Bug river and bottom sediments was as follows: Pb, Zn, Co, and Cu sediments>root>leaf>stem, while in the case of Ni and Cr, the contents were greater in roots than in sediment (root>sediment>leaf>stem), although the differences in contents were not large. The study showed that most metals are present in roots and only a small part of them is transported to the stem and leaves. The size of the metal movement within plants may depend on their contents. It was found that for Ni, Cr and Cu in 2014, the bioaccumulation factor was above one, which confirms the high efficiency of metals uptake from the environment as evidenced by statistical analysis. Bioaccumulation factor (BF) was smaller than one for Pb, Co and Zn, confirming the high ability to retain metals in the root. Aquatic plants are an effective barrier for the surface water by accumulating heavy metals in their biomass. Macrophytes are proposed to monitor the river pollution.

Opis:
The study was designed to establish the pollution of the water and bottom sediments as well as the accumulation rates of selected metals (lead, cadmium, zinc, copper, nickel) in the bottom sediments of the pond in Szczytnicki Park in Wroclaw, Poland. Samples for the study were taken from eight locations on four occasions during a 12-month period: in spring (24 April 2008), summer (19 July 2008), autumn (18 November 2008), winter (10 February 2009). The following were determined for the water: temperature, reaction, total hardness and selected metals (Zn, Cu, Cd, Pb, Ni). For the bottom sediments the content and accumulation of the above metals were established. The accumulation rates of the studied metals in the bottom sediments were found to be arranged as follows: Ni > Cu > Zn > Pb > Cd, whereas metal concentrations in the bottom sediments were: Zn > Cu > Ni > Pb > Cd. Lead and cadmium had the lowest accumulation rates and contents in the bottom sediments. The water and bottom sediments covered by the study were found not to be polluted with metals.
Celem pracy była ocena stopnia zanieczyszczenia wody i osadów dennych oraz ocena stopnia kumulacji wybranych metali (ołów, kadm, cynk, miedź, nikiel) w osadach dennych stawu położonego w Parku Szczytnickim. Próbki do badań pobrano z 8 stanowisk, czterokrotnie podczas roku: wiosna (24 IV 2008), lato (19 VII 2008), jesień (18 XI 2008), zima (10 II 2009). W wodzie oznaczono: temperaturę, odczyn, twardość ogólną oraz stężenie metali (Zn, Cu, Cd, Pb, Ni). W osadach dennych analizowano zawartość oraz kumulacje powyżej podanych metali. Współczynniki kumulacji badanych metali w osadach dennych uszeregowane są w sposób następujący: Ni > Cu > Zn > Pb > Cd, natomiast szereg stężeń tych metali w osadzie dennym wygląda następująco: Zn > Cu > Ni > Pb > Cd. Najniższe współczynniki kumulacji i najniższą zawartość w osadzie dennym stwierdzono dla ołowiu i kadmu. Badana woda oraz osady denne należały do niezanieczyszczonych metalami.

The relationship between results from granulometric analyses of by sieving and by planimetry was investigated by numerical simulation of cubes filled with boulders, cobbles and pebbles. Cross-sections through the sediment were simulated and compared with photos of an actual outcrop wall. Volumes estimated on the basis of planimetric analysis using the cross-sections were compared with sieve analyses, thus allowing to determine adjustment coefficients. The coefficients for pebbles and cobbles have a small standard error, but are larger for boulders, which might be a consequence of too small areas formed by the cross-sections.

Opis:
The freshwater sediments were incubated under anaerobic conditions for 570 and 879 days to in vestigate the potential variations in methanogenic pathways due to increasing sediment age and recalcitrance of organic matter. The methanogenic pathways did not shift from acetate fermentation toward CO2 reduction, as indicated by the observed variations of the isotopic composition of methane in natural conditions. It appeared, however, that the observed decrease of methane concentration (from 86 to 39%) and continuous in crease in d13C(CH4) (from –69.7 to –59.0‰) and dD(CH4) values (from –381 to –320‰) resulted mainly from exhaustion of at least one methanogenic substratein the incubated sediments. To better understand processes controlling the variations of delta exp.13C(CH4) and deltaD(CH4) values relative to ageing of organic matter, the method of principal component analysis (PCA) was used. This method offers good comparison of the relation ships between variables when a larger number of parameters control a given process in the same time period. In this study, the PCA indicated three distinctive factors that controlled decomposition of organic matter during the incubation. Factor 1 explained 33% of observed variations among the variables and had positive (0.93–0.92) loadings for electric conductivity and DIC concentration and negative loading for delta exp.13C(CH4) val ues (–0.72). Factor 2 accounted for 28% and had high posi ive loading for deltaD(CH4) value (0.86) and high negative loading for methane concentration (–0.81). Factor 3 accounted for 19% and exhibited high positive loadings for temperature (0.90) and delta exp.13C(DIC) value (0.69). Factors 1 and 2 were directly linked to the methanogenesis and indicated that bigger accumulation of bio-products in sediments is likely important for variations of delta exp.3C and deltaD of methane. This study shows that method of principal component analysis might be a useful tool while studying biogeochemical carboncy cleduring early digenesis of freshwater sediments.

Opis:
Overbank sediment profiles of the channelized and heavily polluted Vistula and Odra rivers were investigated in southern Poland. The sediments are usually represented by sandy layers about a dozen centimetres thick, intercalated with black sandy muds few centimetres thick and rich in organic matter. Accumulation of these sediments started by the end of 19th century. The sediments are contaminated with heavy metals in amounts exceeding background values by two orders of magnitude and contain coal particles dispersed in black layers. These fine sediments initially accumulated over gravel bars at the channel banks due to lateral channel stabilization by stony groynes and bank revetments, constructed in 19th and 20th century. Progressively the sediments, which are up to 4 m thick, became a part of 20–30 m wide floodplain zones along many reaches of the upper Vistula and Odra. The distribution of these sediments is related to the degree of channel narrowing and incision induced by 19th and 20th century channelization.

Opis:
An attempt was made to determine the correlation between the granulometric structure of bottom sediments and the content of speciation forms of phosphorus and selected metals. Using the sedimentation method, the bottom sediments of a thermally contaminated dam reservoir were divided into fast and slow-draining fractions. Measurements of granulometric composition were made, determining the volume proportions of sediment particles in the range of 0.1 m to 650 m. Particle share sizes were determined in the size range: 0.1–50 m (F1), 50–100 m (F2), 100–200 m (F3), 200–400 m. (F4). The study showed that the content of speciation forms of phosphorus and selected metals remains related to the granulometric structure of bottom sediments. The content of organic matter in sediments is determined by the proportion of the smallest particles, from 0.1 to 50 μm, at the same time these particles most strongly aff ect the reduction conditions of sediments. According to Gilford›s correlation thresholds, there was no correlation between the proportion of sediment particles with dimensions of 0.1–50 μm and the concentration of speciation forms of phosphorus. For particles with dimensions of 50–100 μm, the strongest correlation was observed for the concentration of the EP fraction and for the WDP fraction (r2 = 0.4048, r2 = 0.3636). A strong correlation between the size of sediment particles and the concentration of speciated forms of phosphorus was noted for particles with dimensions of 100–200 μm and 200–400 μm. The coeffi cient of determination was forAAP, EP, WDP and RDP, respectively: 0.8292, 0.891, 0.7934, 0.47. The relationship between particles in the 0.1–50 m range and iron (Fe) concentration, R2 – 0.3792, aluminum (Al) R– 0.3208, and zinc (Zn) R2 – 0.4608, was classifi ed as medium. For particles in the 50–100 m range, a medium correlation with calcium (Ca) and magnesium (Mg) concentrations is apparent, R2 0.4443 and 0.3818, respectively. For particles 100–200 mm and 200–400 mm, an almost full correlation is noted for iron (Fe) R2 – 0.9835, aluminum (Al) R2 – 0.9878, calcium (Ca) R2 – 0. 824, very strong for manganese (Mn) R2 – 0.6817, and zinc (Zn) R2 – 0.7343. There is a very strong correlation between the concentration of the AAP fraction with the concentration of iron (Fe) R2 – 0.8694 and a strong correlation between the concentration of EP with the concentration of iron (Fe) R2 – 0.609. There is a strong correlation between the concentration of theAAP and EP fractions with the concentration of aluminum (Al) R2 – 0. 6253 and 0.8327. The concentration of AAP and EP fractions with the concentration of calcium (Ca) R2 – 0.5941 and 0.7576 remains in a strong relationship. The correlation between the concentration of RDP fractions and the concentration of magnesium (Mg) and manganese (Mn) remains in a medium relationship. The concentration of the EP fraction (Olsen-P) is in a strong relationship with the concentration of organic matter (R2 –.0.6763). No correlation was found between the concentration of the residuum form and the concentrations of organic matter, iron (Fe) and aluminum (Al).A medium correlation was found between the concentration of the residuum form and the concentration of calcium (Ca), magnesium (Mg), manganese (Mn) – R2 = 0.4206 and zinc (Zn).

Opis:
The article presents the results of research from the Mokrzeszów site in the Sudetic Foreland. Lithopetrographic and sedimentological analyses of sediments from the Middle Polish Glaciations (Early Saalian, Odranian, MIS6) in this area indicate the overrepresentation (90–95%) of large Scandinavian erratics. The deposits, representing a repetitive sequence of Gp-Gms-Sp-Sh/Sr(Dmm) lithofacies, accumulated during at least two episodes of glacial outburst floods and six sedimentary cycles. High-energy flows are estimated for the Gms and Gp facies at about 5 m∙s−1 and low-energy flows indicate 0.8 m∙s−1 for the Sp/Sh/Sr facies, to the lack of flow (Fm). The sedimentary sequences confirm the existence of a fan, which may have originated as a subaqueous steep coarse-grained fan in glacial-flow-lake-outburst floods that formed between the ice sheet front and the morphotectonic edge of the Sudetic Marginal Fault line and within the Roztoka-Mokrzeszów Graben, or as an aerial, piedmont fan on the Sudetic Marginal Fault edge. The sediments show discontinuous deformations – gently sloping faults and fractures from glacioisostatic stresses. The fault activity is probably related to the reactivation of the faults due to ice loading during or after the older Saalian glaciation.

Opis:
The aim of this study was to determine possibilities for management of hard coal mine water sediments in geotechnical solutions and reclamation of lands degraded by mining and industrial activities. The mean sample of sediment collected at settling tank inlet was examined to assess geotechnical, physical and chemical properties of this material. Furthermore the effect of reclamation of subsidence trough where the mine water sediment were used was evaluated. Evaluation was carried out on the basis of substratum properties and examination of spontaneous vegetation (species composition and condition) overgrowing the reclaimed area. Survey results revealed that in geological respect water mine sediments responded to sandy silt of low permeability and high organic parts content. It also showed low contamination level. Heavy metals concentration did not exceed threshold limit values for group of grounds B, which were farmlands, forest lands and trees and shrubs covered lands. The washout test discovered that only nickel concentration was exceeded. The stated salinity was rather high, but would be possible to reduce by washing through the profile e.g. by precipitation. Survey of spontaneous vegetation that had developed on the reclaimed area indicated that after 12 years trees and herbaceous plants rooted in the isolation mineral layer did not show any morphological or physiological disorders and it developed similar to vegetation in neighbouring natural habitats. Preliminary studies show that some modifications of mine water sediments properties should be applied to use it e.g. for levelling the ground or soil substitutes production. The mixtures that would be managed as soil substitutes potential ingredients could be e.g. hard coal shales, sewage sludge, lime or fly-ash produced from burning of hard coal.

Opis:
Na wstępie przypomniana została specyfika geotermii i termogeologii ze szczególnym zwróceniem uwagi na wskaźnik mocy cieplnej i wskaźnik efektywności energetycznej jako podstawowych narzędzi stosowanych w tych domenach geoinżynierii cieplnej. Następnie zaprezentowano Pojezierze Kaszubskie jako obszar o wysokich walorach przyrodniczo-krajobrazowych. Obszar ten posiada również potencjał dla powstania ośrodków typu spa, które mogłyby się stać główną osią zrównoważonego rozwoju turystyki w tym regionie. W perspektywie ewentualnej specjalizacji lokalnej w zakresie tej branży oceniono przydatność geotermiczną i hydrogeotermiczną zasobów rozpatrywanego terenu. Stwierdziwszy słabą dostępność głębokich zasobów hydrogeotermalych w rozpatrywanym regionie Niżu Polskiego, na przykładzie gminy Chmielno rozważono możliwości wykorzystania przypowierzchniowego, niskotemperaturowego potencjału energetycznego. Dla tego regionu zaprezentowano główne wyniki analizy uwarunkowań wykorzystania energii cieplnej płytkich warstw wodonośnych. Przeprowadzono także wstępną ocenę możliwości magazynowania ciepła w płytkich warstwach wodonośnych na skalę Pojezierza Kaszubskiego.
Firstly, the specific application domains of geothermal and thermogeological disciplines are reminded with particular attention to the significance of the Power Factor and Coefficient of Performance. Secondly, a briefly overview is given of the Kashubian Lake District with regard to the high landscape value and the natural beauty of this site with a view of introducing a scenario of the sustainable development of tourism focused on spa activities. In this hypothesis, a brief assessment of the geothermal and hydrogeothermal suitability of this lake district is carried out. Thirdly, an assessment of subsurface low temperature potential is proposed, because of the very poor availability of deep geothermal resources in the considered region of the Polish Lowland. This analysis is expanded to include the low enthalpy potential of the shallow aquifer with a focus on the territory of the Chmielno municipality. Finally, a preliminary analysis of the shallow ground waters suitability for the Aquifere Thermal Energy Storage is conducted on the scale of the lake district referred to in this paper.

Opis:
W pracy omówiono kompleksową analizę petrograficzną osadów lodowcowych, obejmującą frakcję żwirów średnioziarnistych i gruboziarnistych. Podano cel i zakres badań oraz zaprezentowano znaczenie i rolę analiz petrograficznych. Przedstawiono zależność składu petrograficznego od frakcji osadu i jego genezy. Analizę petrograficzną omówiono w aspektach terenowym, laboratoryjnym i kameralnym. Podano również możliwości zastosowania analizy petrograficznej do celów litostratygraficznych oraz poznawczych w świetle analizy materiału kamiennego budującego obiekty dziedzictwa kulturowego.
The paper discusses a comprehensive Polish petrographic study of glacial sediments, including a fine and coarse gravel. The purpose and scope of research as well as the importance and role of the petrographic analysis is presented. The dependence of petrographic composition on the sediment fractions and its genesis is discussed. The petrographic analysis is discussed in the aspects of field, laboratory and intimate work. The paper provides the possibility of applying for the petrographic analysis due to lithostratigraphic purposes; it also shows how stone buildings of cultural heritage can be analysed in the light of the petrographic analysis.
