The underlying principles and content of new technology for automated hydrological predictions of poorly gauged and ungauged basins were reviewed herein. Basin classification principles depending on the availability and spatial-temporal discreteness of the observations of meteorological and hydrological variables were proposed. The prediction procedure for large river systems insufficiently covered by hydrometeorological survey was outlined. The prediction methodology for Sông Sê San river basin, which is the left tributary of Mekong river, was tested. The possible options for preliminary calibration and validation of MLCM3 predictive model (Multi-Layer Conceptual Model, 3rd generation), developed within the framework of set task, were described. The software, implementing the streamflow prediction method for ungauged and poorly gauged special basins of large rivers tributaries, was tested.

Opis:

This study represents a re-investigation of two historical fossil discoveries, Callibrachion gaudryi (Artinskian of France) and Datheosaurus macrourus (Gzhelian of Poland), that were originally classified as haptodontine-grade sphenacodontians and have been lately treated as nomina dubia. Both taxa are here identified as basal caseasaurs based on their overall proportions as well as dental and osteological characteristics that differentiate them from any other major synapsid subclade. As a result of poor preservation, no distinct autapomorphies can be recognized. However, our detailed investigations of the virtually complete skeletons in the light of recent progress in basal synapsid research allow a novel interpretation of their phylogenetic positions. Datheosaurus might represent an eothyridid or basal caseid. Callibrachion shares some similarities with the more derived North American genus Casea. These new observations on Datheosaurus and Callibrachion provide new insights into the early diversification of caseasaurs, reflecting an evolutionary stage that lacks spatulate teeth and broadened phalanges that are typical for other caseid species. Along with Eocasea, the former ghost lineage to the Late Pennsylvanian origin of Caseasauria is further closed. For the first time, the presence of basal caseasaurs in Europe is documented.

Opis:

The Rock-Eval source rock characteristics, mineral composition and type-porosity of reservoir horizons, and origin of natural gas in the Devonian of the Lublin and Lviv basins are described. In the Lower Devonian, the TOC content ranges from 0.01 to 1.82 wt.% in the Lublin Basin, and from 0.01 to 0.45 wt.% in the Lviv Basin. Transformation of organic matter varies from immature in the Lochkovian (Lviv Basin) to mature and overmature in the Emsian (Lublin Basin). The organic matter contains mainly Type-II kerogen, and underwent primary and/or secondary oxidation processes. In the Middle Devonian, the TOC content varies from 0.00 to 1.63 wt.% in the Lublin Basin, and from 0.02 to 0.64 to 2.35 wt.% in the Lviv Basin. The organic matter contains mainly Type-II kerogen and is immature in the Givetian of the Lviv Basin and mature in the Eifelian of the Lviv Basin and in the Eifelian and Givetian in the Lublin Basin. In the Upper Devonian, the TOC content is from 0.02 to 2.62 wt.% in the Lublin Basin, and from 0.04 to 1.43 wt.% in the Lviv Basin. Type-II kerogen dominates in both basins. Organic matter is mature in the Upper Devonian in the Lublin Basin and in the Famennian of the Lviv Basin and overmature in the Frasnian of the Lviv Basin. The reservoir horizons in the Devonian of the Lublin and Lviv basins are developed in clastic, carbonate and sulphate rocks. Terrigenous rocks form several separate horizons in the Lower and Middle Devonian of the Lviv Basin, and in the Upper Devonian (Famennian) of the Lublin Basin. Their filtration properties relate to intergranular porosity, while the fracture space has subordinate significance. Carbonate rocks form thick saturated horizons in the Givetian in the Lviv Basin, and in the Eifelian, Givetian and Frasnian in the Lublin Basin. Their filtration properties are produced by fracture porosity. Sulphates and carbonate-sulphate rocks with fracture and cavern porosity play a role as reservoir horizons in the Middle Devonian of the Lublin Basin. The natural gas collected from the Upper Devonian of the Lublin Basin was generated mainly during low-temperature thermogenic processes, from Ordovician–Silurian Type-II kerogen. The gas from the Middle Devonian reservoirs of the Lviv Basin was produced from Ordovician–Silurian Type-II kerogen and partly from the Middle and Upper Devonian mixed Type-III/II kerogen with maturity from about 0.9 to 1.4%. Carbon dioxide was formed by both thermogenic and microbial processes. Molecular nitrogen was generated mainly through thermal transformation of organic matter and also from destruction of NH4-rich illite of the clayey facies of the Ordovician–Silurian strata.

Opis:

The Shaximiao Formation (Sichuan Basin, China), and the corresponding Chuanjie Formation of the neighboring Yunnan Basin (Sichuan-Yunnan Basin), representing continental Mesozoic strata, are distinguished from other Chinese Mesozoic units because of the large area over which they are distributed, their lithological characteristics and their abundant vertebrate fossils. This paper analyses and summarizes the dinosaur fossils from the Shaximiao Formation and compares them to other vertebrate groups of the same or similar ages, both in China and abroad. For the first time, this paper presents the viewpoint that the upper member of the Shaximiao Formation is of Middle Jurassic age (Bathonian–Callovian). Furthermore, we claim that the entire Shaximiao Formation is of Bajocian–Callovian age (middle-late part of Middle Jurassic). This conclusion is supported by the age inferred from invertebrate fossils and radiometric dating (165–178 Ma). The composition, evolution and geological age of the vertebrate fauna (particularly dinosaur fossils), as well as their comparison to the dinosaur fauna from the other parts of the Sichuan-Yunnan Basin (Chuanjie Fm.) is discussed. Middle Jurassic dinosaur assemblages from China show marked differences compared with other dinosaur assemblages in the world, and this is explained by geographical isolation.

The aim of this study was to use the structural restoration technique to verify the correctness of the structural and palaeothickness maps created during the BLUE GAS Project. On the basis of well data as well as refined structural and palaeothickness maps of Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic and Cretaceous horizons, a cross-section running across the Baltic Basin, the Mazury High and the Podlasie Basin was created. During the restoration process, the effects of compaction and fault activity were removed sequentially. The amount of erosion was estimated on the basis of the corrected palaeothickness maps. The resulting restoration is geologically reasonable and therefore both the structural and palaeothickness maps should be regarded as reliable. The reconstruction also allowed reproduction of the initial geometry and thickness of the Cambrian–Devonian strata and the recognition of three main episodes in the evolution of the sedimentary cover of this part of the East European Craton. The first episode was related to the deposition of the Lower Palaeozoic (up to the Lower Devonian) sedimentary complex on the relatively flat surface of the East European Craton edge. During the second episode, lasting most probably to the Permian, the Baltic and Podlasie Basins subsided significantly. The amount of subsidence was much higher in the Podlasie Basin. The third episode is related to the deposition of the almost flat-lying Mesozoic–Cainozoic complex.

Opis:

Coal bed methane (CBM) may become an important source of energy in Upper Silesian Coal Basin. Coal bed methane in Poland occurs within three coal basins of which the best recognized and most promising is the Upper Silesian Coal Basin. Approximately 80.1% of proved balance of coal deposits resources in Poland occurs in the Upper Silesian Coal Basin, where 50 fields are operated by 28 mines. Thus, since early 90s of the 20th century the USCB is attractive for foreign companies which perform evaluation of coal bed methane obtaining possibility as main fossil. However, all previous attempts to commercial production of CBM did not bring expected results, but they constitute extensive information database for current and future research towards CBM exploitation. Prognostic resources of coal bed methane in USCB are estimated to 107 bln m3. Recoverable balance resources are estimated to 87.6 bln m3. Much smaller perspectives are related to the poorly identified regions of Lublin Coal Basin and Lower Silesian Coal Basin. It is estimated that balance resources of hard coal in LCB, represents approximately 19.2% of Polish hard coal balance resources.

Opis:

The paper analyses possible causes of failure of the rotating footbridge over the Ustka port channel. In July, 2015, strange behaviour of this object was observed in the form of excessive vibrations of bridge platform suspension rods, with the accompanying acoustic effects. A preliminary geotechnical analysis has revealed that this destructive effect was caused by the nearby construction works, namely construction of a fishing basin and communication routes in the area close to the bridge, which affected the bridge lashing rod foundation settings. Ground vibrations generated by certain construction activities were likely to have direct impact on decreasing the bearing capacity of these rods and increasing the susceptibility od the piles to extraction. After detecting the above problems in bridge operation, its geodetic monitoring was started. The data recorded during this monitoring, along with the results of force measurements in the rods, have made the basis for a series of numerical simulations, performed in the Finite Element Method (FEM) formalism. The bridge structure was analysed in the conditions defined as the emergency state. Extreme efforts of bridge elements and its dynamic characteristics were examined. A possible source of strange behaviour of the footbridge during its operation which was recognised during these simulations was the coincidence of the global natural frequency of the entire bridge structure with local vibrations of suspension rods, at the frequency approximately equal to 1 Hz. This situation was likely to lead to the appearance of the so-called internal resonance phenomenon. As a final conclusion of the research, recommendations were formulated on possible object oriented corrective actions.

MIKE SHE software was used to estimate recharge into the aquifers of Ogun and Oshun Basins. Abeokuta within the Ogun Basin and Oshogbo in the Oshun Basin are sub-divided vertically into two components: atmosphere, and unsaturated zone. The atmosphere zone comprises of rainfall and potential evapotranspiration, while the unsaturated zones, comprises of the Basement Complex and Sedimentary rock. Daily records from two rainfall stations, Oshogbo station (2008–2011) and Abeokuta station (2010–2014) water years were obtained for simulation of groundwater recharge processes using MIKE SHE model. The simulation results showed that daily groundwater recharge is influenced by rainfall and ranges from 0 mm∙day^–1 in January when there was an insufficient rainfall in the two stations to 10.89 mm∙day^–1 in Abeokuta and 29.85 mm∙day^–1 in Oshogbo in the month of August when the soils had attained field capacity. The study found out that there are more daily groundwater recharge in Oshun basin compared to that of Ogun basin. This was alluded to more rain-fall and less evapotranspiration recorded at Oshun basin as compared to Ogun basin coupled with the sedimentary soil which allows more movement of water into the aquifer of the basin. It is recommended MIKE SHE model should be used to estimate recharge in other basins in Nigeria and Africa for quick and effective daily recharge calculations to permit better and scientific decision making in these areas.

The genus Disciseda in Poland until now was represented by two species: Disciseda bovista and D. candida. During the mycological investigations on the macromycetes fungi in the xerothermic grasslands of the Nida Basin, a species new for Poland from this genus, namely Disciseda verrucosa, was recorded. The basidiocarps of this species were found in the village Gacki (50°26'41" N, 20°36'34" E; ATPOL square Fe 24), in the village Wola Zagojska (50°26'41" N, 20°36'34" E; ATPOL square Fe 24), and in the Krzyżanowice Reserve (50°27'13" N 20°33'36" E; ATPOL square Fe 14), in the Ponidzie region. The basidiocarps of D. verrucosa were collected in the xerothermic grass, within Festucetum pallentis and Sisymbrio-Stipetum capillatae associations in the neighborhood of Festuca pallens, Stipa capillata, and Thymus marschalianus. On the basis of collected basidiocarps, macro- and microscopic characteristics were described and compared with other European Disciseda species. An identification key to the species of Disciseda occurring in Poland is given.

Opis:

New palynostratigraphical data concerning the Carboniferous sedimentary succession of SW Poland has been obtained from the Czerńczyce IG 1 borehole and the Brońsko boreholes on the northern slope of the Wolsztyn-Leszno High, where the oldest rocks were expected. The miospore assemblages recovered from the Czerńczyce IG 1 borehole allowed assignment of the interval studied to the Marsdenian (Namurian B) and Yeadonian (Namurian C). These results, supplemented with previous palynostratigraphical data, refute the existence of a stratigraphic gap between the early Namurian and Duckmantian (Westphalian B). The reinterpretation of the unpublished miospore results of Górecka et al. (2000b, 2001a) from the Carboniferous rocks from the Brońsko boreholes, also indicate that they should actually be assigned to the upper Marsdenian and Yeadonian. All analysed miospore assemblages are mixed and contain abundant reworked specimens. The results above complement previous opinions and permit a re-evaluation of the stratigraphy of the Carboniferous siliciclastic succession of SW Poland. Its sedimentation was certainly initiated in the earliest Namurian or earlier and probably lasted without long gaps until the Stephanian. The abundance and common occurence of reworked miospores indicate the age of rocks eroded during Carboniferous deposition. The lithological and palynofacial features of the late Namurian rocks from the Czerńczyce IG 1 borehole may be interpreted as a record of the shallowing of the sedimentary basin, including the possibility that some of the sedimentation occured in continental conditions. This means that the transition from the deep marine environment to shallow-water or even continental habitats likely had already taken place by the late Namurian. This suggestion, together with the tectonic deformation dated as post-Bolsovian, corresponds to the timing of the deposition and deformation in the German part of the Variscan Foreland Basin.

One hundred twenty five miospore taxa were determined and two miospore zones were distinguished. Deposits from Konradów and Biały Kamień belong to the Stenozonotriletes triangulus-Rotaspora knoxi (TK) Zone, correlated to the middle Namurian A. Deposits from Szczawno Zdrój appeared to be younger, because they represents the Lycospora subtriquetra-Kraeuselisporites ornatus (SO) Zone (late Namurian A).

The Kelani River is the second largest watershed in Sri Lanka and the main water-supply intake point for the Greater Colombo. The present study focuses to identify the sources of pollutants of the meandering zone of the Kelani River, particularly due to the absence of more recent information. Accordingly, a survey was conducted to obtain information on industrial discharges, anthropological, and social activities within the area of 15 m from left and right banks of the river. The high contaminations (total and faecal coliform – 1100 MPN∙(100 cm3)–1; COD – 10 mg∙dm–3; BOD – 4 mg∙dm–3) of surface and groundwater are corroborated with the results obtained via the demographic and land usage statistics. Industrial pollutant sources and harmful anthropological practices were identified as major threats to the river basin. In this survey, agriculture and land degradation were identified as issues due to improper land use management. As policy recommendations based on the results of the study, it was identified that the awareness for Kelani River protection should be increased; monitoring and evaluation of the Kelani River basin under a management plan should be implemented; and stakeholder and private partnerships contribution to the sustainability of the Kelani River basin should be established.

Opis:

The cave of Smocza Jama located in the centre of Kraków is developed in the Wawel Horst built of Upper Jurassic limestone and surrounded by grabens with Miocene clays. The cave is composed of two series: the old one has been known for ages and the new one was discovered when an artificial shaft was mined in 1974. The new series comprises small chambers separated by intervening thin walls while the old series consists of three connected together spatial chambers. The cave abounds in extensively developed solution cavities – cupolas and ceiling pockets. The internal fine-grained deposits, predominantly representing clay fraction are built of illite, mixed layer illite-smectite, kaolinite and iron oxides. They are probably the residuum after dissolution of Jurassic limestone. The cave originated in phreatic condition due to water input from below. The new series represents juvenile stage of cave evolution. The water rose through fissure-rifts located in chamber bottoms, circulated convectionally within particular chambers, finally led to bleaching of intervening walls, and hence to connection of the neighbouring chambers. The evolution of the old series is far more advanced. The rounded solution cavities imply that the cave was formed by water of elevated temperature. The lack of coarse-grained fluvial deposits, Pleistocene mammal remains and Palaeolithic artefacts prove that the cave was isolated since its inception till Holocene time. The cave originated due to artesian circulation, when the Wawel Horst was covered by imper- meable Miocene clays. A foreland basin with carbonate basement, filled with fine-grained molasse-type deposits seems to be particularly favourable for the development of artesian caves.

Opis:

Paleozoic organic-rich mudrock ("shale") units were deposited on the eastern margin of the United States of America from the initial Cambrian rifting to the assembly of Pangaea after the Devonian. Two of these organic-rich shale units the Ordovician Point Pleasant-Utica and Devonian Marcellus Shale of the northern Appalachian basin are some of the most active shale gas and liquids plays in the world, and a significant component in the United States energy market. Unconventional hydrocarbon plays are often referred to as statistical plays due to their high degree of heterogeneity, and present challenges for characterization and exploitation. Productivity depends upon an inter-related set of reservoir, completion and production characteristics. A key control on success is regional geology and sequence stratigraphy, in particular the geographic and stratigraphic distribution of organic matter, silica, and carbonate. The distribution of these key elements has been modeled at the basin and local scales. A 3-D mudrock lithofacies model is constructed using sequence stratigraphy to constrain mineral composition, rock properties and organic content. Core analysis and log data were used to calibrate the model from core scale to well scale and finally to regional scale. Geostatistical approaches were used to develop a quantitative relationship between conventional logs and lithofacies, and to model the distribution of mudrock lithofacies in three- dimensions. Controlled primarily by dilution, organic matter productivity, and organic matter accumulation distribution of organic-rich mudrock lithofacies was dominantly affected by water depth and distance to shoreline. The controls on mudrock reservoir quality are subtle and heterogeneity present in Utica and Marcellus results in regional and local well production variations. The proposed 3-D lithofacies modeling approach aids in recognizing geologic and engineering targets, designing horizontal well trajectories, targeting fracture stimulation strategies and understanding shale depositional environments and processes. The proposed approach can be extended to other organic-rich shale reservoirs.

The Mekong is a transboundary river chich runs through China, Myanmar, Thailand, Laos, Cambodia, and Vietnam. Its basin, where more than 70 mln people live, creates the lar gest inland fishery and comprises a main skurce of fresh water, also used in agriculture. But the most tempting is its hydropower potential which has been developed especially by China. The growing number of hydropower plants In the upper stretch poses a real threat for Lower Mekong basin countries. This article examines the role of China in the Mekong region and analyzes relations over the water resources between the Middle Kingdom and other riparian states. Paper indicates the main purposes of China’s hydropolitics of the Mekong river basin, its hydropolitical strategy towards this region and gives an answer whether China wants to cooperate or develop its hydropower potential regardless of consequences for Indochinese states and possible conflicts.

Opis:

This paper presents a new sedimentological and palaeogeographic interpretation of the Early to Middle(?) Triassic continental deposits in the Wleń Graben and the Krzeszów Brachysyncline (Sudetes, SW Poland). These two tectonic subunits, located in the peripheral segments of the North Sudetic and Intra-Sudetic synclinoriums, respectively, represent the crucial elements for deciphering the post-Variscan palaeogeographic evolution of the NE termination of the Bohemian Massif. Sedimentological studies and facies analysis show that the Early Triassic siliciclastic deposition in both areas was dominated by fluvial sedimentation of the typical Buntsandstein facies within a gently sloping alluvial plain, locally followed by ephemeral lake environments in the late Early or Middle(?) Triassic. The lithofacies and the measured palaeocurrent directions indicate that the area was drained by braided streams flowing towards the northwest and north. Individual fluvial channels had depths not exceeding 1 m and widths of up to a few metres. Overbank deposits are poorly preserved due to the lateral shifting of channels. Based on available borehole data, an analysis of isopach maps was performed for the first time in the study areas. The study areas are presently separated by crystalline units devoid of sedimentary rocks, but the analysis indicate that they might have been in constant or periodical connection during the Triassic. It is concluded that the present-day extent of Triassic deposits is a result of the primary basin configuration combined with the Middle Triassic to Late Cretaceous erosion and post-Cretaceous tectonic uplift. The paper summarizes the present state of research on the continental Triassic preserved in the terminal parts of the North Sudetic and Intra-Sudetic synclinoriums, presents the first detailed sedimentological logs, and proposes new palaeogeographic interpretation. New findings include bioturbation structures, such as plant-root traces or tunnels formed by invertebrates and possible tetrapod footprints, which shed new light on the sedimentological interpretation of the continental Mesozoic deposits in the NE part of the Bohemian Massif.

Opis:

An issue of mean residence time (MRT) evaluation, i.e. the period of time from rainfall until drainage of groundwater by rivers (Danube River Basin, Vistula River Basin and Narew River Basin), is discussed Asimple method of evaluating the groundwater MRT for the Danube River Basin based on tritium data is introduced. It has been confirmed that the historical tritium level in the rivers, being higher than in precipitation, has its end and is reversed, opening a new pathway in understanding the surface-groundwater interaction and specifically in evaluating MRT of groundwater. The authors have defined a separate notification for mean residence time of the whole water in the basin (τ) and mean residence time for groundwater in the basin (τwp). Based on the tritium study the obtained τ values are 6.5 and 5.7 years for the Vistula River Basin (VRB) and the Narew River Basin (NRB), respectively. In turn, the obtained τwp values are 8.0 and 6.0 years, respectively. NRB is a lowland plain and a morphologically, geologically and hydrogeologically uniform basin. The obtained τ wp of groundwater is thus representative for the whole basin. Instead inmorphologically non uniform VRB basin groundwater τwp is a generalized value,i.e.averaged over contributed parts of the basin.

Rocks from the Mo-1 well from the Barnówko-Mostno-Buszewo (BMB) oil and gas field have been studied aiming at constructive results for application in exploration for oil and gas. The study focuses on carbonate deposits from the Main Dolomite horizon, commonly diagenetically altered, where the pore space has been filled by dolomite and anhydrite. Standard petrological analysis was conducted, wide fluid inclusion analyses performed and geochemical character of bitumen determined. Based on microscopic fluorescence studies, three types of fluid inclusions have been distinguished in the vertical column of the well: one-phase non-fluorescent (methane), two-phase non-fluorescent (brine), and two-phase fluorescent inclusions (oil). These three types, further studied microthermometrically, display characteristics of fluid fillings present in the basin and closed as the inclusions in minerals.

Opis:

Rainfall in the Lake Tana basin is highly seasonal and the base flow contribution is also low resulting in the need for reservoirs to meet the agricultural demand during the dry season. Water demand competition is increasing because of intense agricultural production. The objective of this study is to develop water balance models. The Mike Basin model has been selected for water allocation modelling and identifying potential changes needed to the existing water allocation scheme to reduce the stress due to increased water demand. The study considers baseline and future development scenarios. The construction of new dams results in two competing effects with respect to evaporation loss. The first effect is increased evaporation from new reservoirs, while the other is reduced evaporation from the Lake Tana as a result of a decreased surface area of the lake and reduced inflow of water to the lake. Once a dam is built, there will be an additional free water surface area and more evaporation loss. In dry months from January to May, the irrigation water demand deficit is up to 16 Mm3. It is caused by reservoirs built in the basin, which reduce the inflow to the Lake Tana. The inflow varies between wet and dry months, and there is more water flow in wet months (July, August and September) and reduced flow in dry months because of the regulatory effects produced by the reservoirs.

It is preserved as impressions, flattened casts, moulds and isolated leaves. So far, only one small fern specimen, determined as Sphenopteris sp., has been found. These elements probably were transported to the site of deposition and did not grow where they were buried.

Opis:

The site of Świerszczów 28 was discovered in 2012 during field works connected with the construction of the Hrubieszów ring-road. The site is located on the border between Horodło Bar (Grzęda Horodelska) and Hrubieszów Basin (Kotlina Hrubieszowska). As a result of excavations, 221 non-portable features were found, of which 81 were dated based on artefacts found in their fills. The oldest phase of settlement is represented by artefacts connected with the Rzeszów phase of the Malice culture. Nine features yielded a series of 66 fragments of vessels (the majority of them were found in one feature, i.e. pit no. 243–53 sherds) which, in terms of technology, belong to the category of medium- or thick-walled pottery. Pottery forms represent vessel types typical of the Malice culture: biconical vessels – both pots and amphorae, profiled bowls and beakers on hollow feet. Vessels were decorated with ornamentation motives arranged in horizontal bands. The most typical ornaments were notches (corrugations), fingernails notches, “pinched” impressions and fingertips imprints. Knobs and plastic belts also appeared. Flint artefacts are represented by only 11 specimens. Two of them merit particular attention: an end-scraper with an oval front from feature no. 243 and a blade found in the layer of humus. Nine artefacts were made of Volhynian flint, the remaining two are burnt. The traces of the Malice culture occupation at Świerszczów 28 site are connected with a small settlement. The analyzed collection of artefacts is linked with the oldest segment of the Rzeszów phase (IIa) of the Malice culture, connected with trans-Carpathian influences from the proto-Tiszapolgár culture and phase A of the Tiszapolgár culture, which in terms of absolute chronology corresponds to the last quarter of the fourth millennium BC.

The oldest of those, ‘Sisters of Noahʼ (Lebanon) are believed to be 5000–6000 years old. The most numerous groups of monumental olives were reported from Apulia in Italy and Albania. The oldest and biggest olive trees could be remnants of ancient plantations from the Hellenic and Roman times, but this hypothesis should be confirmed in a detailed study.

Opis:

The chitinozoan successions (zonation) in the Llandovery and Wenlock deposits, accumulated along the northern shelf edge of the Livonian Basin, an embayment of the Palaeobaltic sea, is studied and used for time-rock correlation of the area. Analysis of the ranges of 180 taxa from 44 sections (41 of them well-sections) by graphic correlation revealed largely compatible successions of taxa as well as local stratigraphic gaps in both shelf and basin sections. Alternatives to graphic methods also produced composite standards based on stratigraphic relationships (below, co-occurring, or above) of taxonomic ranges and considered as palaeontological time scales (composites) similar to zonal schemes. We constructed such a scale using the DISTR algorithm to analyse the distribution of 84 taxa and recognized 41 datum planes. This scale includes the traditional regional and global chitinozoan zones and the associated chronological standards (including regional stages). The BioGraph and DISTR algorithms were used to study diversity changes, and to illustrate patterns of originations and extinctions of the chitinozoans. Correlation plots between composite standard and particular sections reveal variations in sedimentary rock accumulation patterns, supporting the results of sequence stratigraphic analysis of the study interval.

Opis:

Flooding in East-Central Europe in May and June 2010 also affected the Odra River Basin. Unlike a typical summer flood scenario, in 2010 intensive precipitation was observed as early as May. Also, the location of the most intensive rainfall shifted to the catchments of the right bank tributaries of the Odra River. This paper presents the climatological assessment of the precipitation totals that caused two flood waves on the Odra River. The assessment was carried out with the use of selected indicators: monthly precipitation totals, daily precipitation totals, number of days exceeding given precipitation levels, number of days with precipitation of a given probability of exceedance and intensity, duration and accumulation of precipitation for a number of consecutive wet days. The reference values for climatological indicators were developed for the period 1966-2009. The values of the selected indicators were analyzed in terms of flood hazard in relation to the hazard gradation. The results show that the observed precipitation had the character of an extreme event with respect to its magnitude, duration and spatial extent. The catchments with recognized high levels of flood hazard were affected by the flood wave. The flood situation caused by the extreme precipitation was evaluated in the context of the largest floods in this region during recent decades.

Opis:

A set of geological maps and geological cross-sections was prepared to document the geological setting of sedimentary basins developed on the western slope of the EEC and adjacent areas to the west. On the basis of these data and literature on the subject, the evolution of the sedimentary basins in the study area was reviewed, with special emphasis on the Ediacaran–Lower Palaeozoic basin. The basin originated during late Ediacaran rifting, related to the latest stages of breakup of the Precambrian super-continent Rodinia/Pannotia, associated with large-scale igneous activity. The rifting ultimately led to the formation of the Tornquist Ocean and subsequently, during the latest Ediacaran to Middle Ordovician, the SW margin of the newly formed Baltica became a passive continental margin. The upper Cambrian depocentre in the Biłgoraj-Narol Zone and the Łysogóry Block tentatively is interpreted as a small, narrow foredeep, related to the docking of the Małopolska Block to the western margin of Baltica. From the Late Ordovician through the Silurian, a gradual change to a collisional tectonic setting is observed across the entire SW margin of Baltica, as well as in the zones adjacent to it from the west, which together became the site of development of the extensive Caledonian foredeep basin, related to the convergence and collision of Avalonia and Baltica. The oblique character of the collision resulted in a prominent diachronism in the development of the foredeep basin. This refers to the initiation of basin subsidence, the starved basin phase, the main phase of rapid subsidence and supply of detritus from the west, and the termination of basin development. The Early Mississippian (Bretonian) phase of uplift and erosion and, to a lesser degree, also the Late Pennsylvanian one significantly affected the structure of the western EEC. During the Mississippian, extensive magmatic activity took place at the SW margin of East European Craton, in the region referred to here as the Baltic-Lublin Igneous Province.

The occurrence of Eckicrinus radiatus (Schauroth) is reported in the area for the first time. Based on the stratigraphic distribution of the crinoids, the ranges of three crinoid zones (Dadocrinus Zone, acutangulus Zone and dubius Zone) have been constrained. A modified correlation between the Lower Muschelkalk deposits of the North-Sudetic Basin, Upper Silesia and the Holy Cross Mountains is proposed.

Opis:

Polish bituminous coal basins are associated exclusively with Carboniferous deposits, differing in origin and geological structure. This paper presents only a short review of papers mainly of Polish authors on the geological structure, stratigraphy of coal-bearing deposits, quality of coal, as well as selected aspects of economic geology of three Polish bituminous coal basins: the Upper Silesian Coal Basin (USCB), Lower Silesian Coal Basin (LSCB) and Lublin Coal Basin (LCB). The paper provides also an overview on the investigations made on the interpretations of the origin of Polish coal deposits over the last 20 years with an emphasis on coal facies studies. The paper content is related to the conference entitled "Polish Coal” of the 3 rd Polish Geological Congress, which is planned in Wroclaw in September 2016. This conference covers a broad spectrum of issues such as: geology of coal basins and coal deposits, coal-bed methane, economic geology, petrology and geochemistry of coal, as well as origin, coalification and quality of coal.

Opis:

Rzeka Mekong, przepływająca przez Chiny, Birmę/Mjanmę, Laos, Tajlandię, Kambodżę oraz Wietnam, tworzy dorzecze, od którego zależy byt ponad 70 mln ludzi. Sytuacja w regionie ma szczególne znaczenie dla rybołówstwa i rolnictwa w ostatnich czterech z grupy wymienionych powyżej państw. Z tego też względu już od lat 50. XX wieku wspomniane kraje indochińskie współpracują wokół zasobów Mekongu, tworząc regionalne organizacje integracyjne. W ostatnich latach największą uwagę w dorzeczu przykuwa hydroenergetyka. Mimo zagrożeń, jakie niesie za sobą budowa dużych i licznych elektrowni wodnych, państwa Półwyspu Indochińskiego, w szczególności Laos i Kambodża, planują rozwój swojego potencjału. Celem artykułu jest analiza relacji hydropolitycznych w dolnym biegu rzeki Mekong, zwłaszcza w perspektywie nowych wyzwań takich jak budowa potężnych obiektów w chińskiej części dorzecza i plany hydroenergetycznej ekspansji w Indochinach. Praca daje odpowiedź na pytanie, czy wskazane powyżej czynniki sprzyjają współpracy, czy też generują coraz więcej konfliktów pomiędzy Laosem, Tajlandią, Wietnamem i Kambodżą.
The Mekong River which runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam creates basin where more than 70 million people live. Situation in this region has great influence on agriculture and fishery, particularly in the last four aforementioned countries. Therefore those states has been cooperating with each other over the water resources since the 1950s. Nowadays, attention is focused on hydroenergy. Despite the fact that growing number of hydropower plants poses a threat for the environment, the Lower Mekong Basin countries, like Laos and Cambodia, are planning to exploit their hydropower potential. The main purpose of this article is to analyze hydropolitical relations between the LMB states, especially in the face of new challenges like functioning of hydroelectric power stations in China and development of water energy potential of the Indochinese Peninsula. Paper gives an answer whether factors listed above foster cooperation among the LMB states or create potential sources of conflicts between those countries.

Opis:

The Carpathian Orava Basin is a tectonic structure filled with Neogene and Quaternary deposits superimposed on the collision zone between the ALCAPA and European plates. Tectonic features of the south-eastern margin of the Orava Basin and the adjoining part of the fore-arc Central Carpathian Palaeogene Basin were studied. Field observations of mesoscopic structures, analyses of digital elevation models and geological maps, supplemented with electrical resistivity tomography surveys were performed. Particular attention was paid to joint network analysis. The NE-SW-trending Krowiarki and Hruštinka-Biela Orava sinistral fault zones were recognized as key tectonic features that influenced the Orava Basin development. They constitute the north-eastern part of a larger Mur-Mürz-Žilina fault system that separates the Western Carpathians from the Eastern Alps. The interaction of these sinistral fault zones with the older tectonic structures of the collision zone caused the initiation and further development of the Orava Basin as a strike-slip-related basin. The Krowiarki Fault Zone subdivides areas with a different deformation pattern within the sediments of the Central Carpathian Palaeogene Basin and was active at least from the time of cessation of its sedimentation in the early Miocene. Comparison of structural data with the recent tectonic stress field, earthquake focal mechanisms and GPS measurements allows us to conclude that the Krowiarki Fault Zone shows a stable general pattern of tectonic activity for more than the last 20 myr and is presently still active.

The proto-Silesian Basin was well developed within the Alpine Tethys during the Late Jurassic times and existed as undivided entity until the significant Late Cretaceous reorganization. The deposits originated within this basin were incorporated into different structural units: Silesian, Subsilesian and Skole. The calciturbiditic Cieszyn Limestone Formation is the oldest Cretaceous flischoidal sequence of the proto-Silesian Basin. This calciturbiditic sedimentation passed gradually into younger siliciclastic deposition.

Opis:

Terravecchia Formation in the Scillato Basin is a good example of development of a post-tectonic basin. Practically continuous exposures across that basin give the rare possibility to observe the lateral distribution of lithofacies and gradual changes of sedimentary succession from an alluvial fan, fluvial plan to lacustrine and, eventually, to marine setting. The alluvial fan deposits are generally represented by polymictic, disorganised or crudely organised conglomerates representing mainly flow and debris flow deposits. The fluvial plain association is characterized generally by cross-bedded sandstones with streaks of conglomerates laid down within a channel bar system. Flood-plain deposits are subordinate. Sedimentary structures suggest deposition in a braided river. The fluvial plain association pass laterally to lacustrine/fluvial plain deposits represented by grey to pinkish mudstones with channelised sandstones. As an effect of subsidence the Scillato Basin was invaded by marine/brackish environment, and marly mudstones and siltstones with subordinate sandstones were deposited. That variability of sedimentary facies can be explained by vertical tectonic movements.
Późnomioceńska formacja Terravecchia zachowana w basenie Scillato, stanowi dobry przykład rozwoju basenu posttektonicznego. Ciąg bardzo dobrych odsłonięć w poprzek basenu pozwolił na szczegółowe obserwacje rozkładu litofacji, struktur sedymentacyjnych oraz asocjacji facjalnych i ich wzajemnych związków. Wyróżnionych zostało kilka środowisk sedymentacyjnych, od stożka aluwialnego, przez rzekę roztokową po środowisko jeziorne i morskie. Osady stożka aluwialnego reprezentowane są przez czerwone i żółte, polimiktyczne zepieńce, o strukturach zarówno bezładnych jak i uporządkowanych, powstałe w wyniku działania prądów i spływów rumoszowych. Osady rzeki roztokowej to głównie przekątnie warstwowane piaskowce związane z różnego rodzaju łachami piaszczystymi. Mułowcowe osady równi zalewowych zachowały się tylko sporadycznie. Osady rzeczne przechodzą lateralnie w mułowcowe osady jeziorne z licznymi osadami kanałowymi w ich dolnej części. Pod koniec rozwoju basenu, w rezultacie subsydencji tektonicznej, nastąpiła ingresja morska i powyżej osadów rzeczno-jeziornych rozpoczęła się sedymentacja osadów brakiczno-morskich z poziomami fauny.

Opis:

The biggest problem in the process of implementation of the new sea areas project or aids to navigation systems is to check the assumptions without compromising security on real waters. Today, digital models are available for easy and inexpensive replacement of the research methods used so far. For this purpose the navigational and maneuvering simulators are perfect. Simulators as a research tools allow you to define a more realistic and accurate data for the study and evaluation sea areas. The purpose of the simulation is to identify and reduce the risk for seafarers during navigation on the waterways, canals and port areas. These include quantitative and qualitative assessment of the canals and fairways construction. The main requirement for a simulation system is to have a multi-task simulation software, which includes effective tools for repositioning and designing safe waterways and port infrastructure. The Institute of Navigation and Maritime Hydrography of the Polish Naval Academy since the eighties of the twentieth century is carried out projects in the field of navigational and hydrographic support of human activities at sea. This is possible thanks to the extensive set of simulation tools. Planning this tasks in a simulators software environment allow not only to design of virtual counterparts of real sea areas, but also to evaluate the quality of manufactured parts before their actual exposure to sea areas.
Największym problemem w procesie realizacji projektu budowy nowych akwenów morskich lub elementów systemów oznakowania nawigacyjnego jest sprawdzenie poprawności przyjętych założeń bez obniżania poziomu bezpieczeństwa na realnych akwenach. Współcześnie dostępne są cyfrowe modele pozwalające na łatwe i tanie zastępowanie dotychczas stosowanych metod badawczych. W tym zakresie idealnie sprawdzają się symulatory nawigacyjno-manewrowe. Symulatory jako narzędzia badawcze pozwalają określać bardziej realistyczne i dokładne dane do badania i oceny dróg oraz akwenów wodnych. Celem symulacji jest identyfikacja i zmniejszenie ryzyka działalności marynarzy w specyficznych warunkach dróg wodnych, kanałów i akwenów portowych. Obejmuje ona ocenę ilościową i jakościową ukształtowania kanałów i torów wodnych. Głównym wymaganiem w odniesieniu do systemu symulacji jest posiadanie wielopoziomowego oprogramowania symulacyjnego, które obejmuje efektywne narzędzia repozycjonowania i projektowania bezpiecznych dróg wodnych i elementów infrastruktury portowej. W Instytucie Nawigacji i Hydrografii Morskiej Akademii Marynarki Wojennej od lat osiemdziesiątych XX wieku realizuje się projekty z zakresu nawigacyjno-hydrograficznego zabezpieczenia działalności ludzkiej na morzu (NHZ). Jest to możliwe dzięki posiadaniu bogatego zestawu narzędzi symulacyjnych. Planowanie NHZ w wirtualnym środowisku symulatorów pozwoliło nie tylko na zaprojektowanie wirtualnych odpowiedników realnych fragmentów polskich obszarów morskich, ale również na ocenę jakości wytworzonych elementów NHZ przed ich rzeczywistym wystawieniem na akwenach morskich. W artykule zaprezentowano możliwości symulatorów na przykładzie planowanego kanału żeglownego przez Mierzeję Wiślaną. Przedstawiono algorytm postępowania podczas tworzenia akwenu i próby manewrowe dla maksymalnej jednostki przewidzianej dla nowo powstałego akwenu.

In this article, an inverted pendulum system is set up to explore the dynamics of a horizontally driven pendulum which exhibits a great variety of dynamical behavior and appears in a wide range of applications in the field of engineering. The facility is efficient to experimentally explore two kinds of coexisting movement patterns in the horizontally driven pendulum, i.e. in-phase and anti-phase patterns between the angular velocity of the pendulum rod and the direction of the driving forces. Theoretical analysis is applied to reveal the regimes of the coexistence of the two movement patterns, which is promising to control the system to a desired pattern.

The paper presents an analysis of changes in the bathymetry of Mierzyńskie lake, located in western Poland. It was found that over the last five decades this lake was characterized by exceptional stability in terms of changes in the surface area and volume of water, which decreased by 3.4 ha and 315,000 m3 respectively. The observed situation is quite different in comparison to the literature analysing the issue of lake evolution in Poland (indicating a faster rate of their disappearance). This specificity is due to the nature of the use of the catchment of this lake, which is characterised by an exceptionally high percentage of forest areas (considered to be the most natural) and negligible anthropopressure.

The results of this work proved that using clean cultures of Thiobacillus ferrooxidans was in this case very proper if we evaluated desulphurisation from the pyrite sulphur point of view. After one month of leaching, the pyrite sulphur was almost gone from the sample still containing a lot of organic sulphur amount of which decreased only slightly. The desulphurisation of pyritic sulphur reached about 71% while the total desulphurisation of coal - 42%.

Opis:

The low temperature oxidation processes which has taken place in lignites and their lithotypes (xylain, humovitrain, semifusain, fusain and liptain) from the East Maritza basin have been studied. The changes occurring in the coals/lithotypes composition and structure during their oxidation have been followed by examining reflectance, microhardness, proximate, ultimate, functional, and increment analyses. The main kinetic parameters such as duration of the induction period, maximum and stationary rates and the apparent activation energies were evaluated. The complex investigation provides a detailed information for the behaviour of low rank coals and their lithotypes towards the action of atmospheric oxygen. Thus some suggestions concerning the mechanisms of their oxidation reactions can be made. The individual way of the genesis of each one of the lithotypes and the resulting physicochemical structure predetermine the basic mechanism of these reactions. However, it has been found that in spite of the similar genesis the lithotypes differ in the mechanism of their oxidation. For xylain the oxidation takes place mainly via aryl radicals yielding tertiary peroxide and carbonyl groups. The oxidation of humovitrain is characterised by the dominant participation of aroxyl radicals resulting in accumulation of primary hydroperoxide and phenol groups. The oxidation of semifusain leads mainly to the formation of molecular products. The oxidation of fusain is found to be essentially different from that of other lithotypes. It is characterised by the formation of carbonyl groups attached to biphenyl aromatic structures. The peculiar petrographic composition and structure of liptain account for the occurrence of oxidation processes accompanied by destruction reactions at relatively lower temperatures. It has been established that the intensity of the oxidation processes varies from one lithotype to an other. Xylain and humovitrain oxidise most intensively. The intensity drops off from the first towards the second member of the corresponding genetic series, i.e. from xylain to humovitrain and from semifusain to fusain.

Opis:

The Callovian and Oxfordian marine sediments of the Jaisalmer Basin constitute the uppermost part of the Jaisalmer Formation, which comprises the Kuldhar and Jajiya members. In the present paper the authors illustrate retrogradational-progradational, more or less symmetrical cycles representing low- to high-energy marine environments. Despite an incomplete sedimentary record in a profile disrupted by a number of omission surfaces, it is possible to distinguish seven such sedimentary cycles in less than 24 m of sedimentary succession. The cycles, often bearing in their upper parts a thick-bedded well-cemented calcareous sandstone/pack- to rudstone, or hummocky cross-stratified beds indicative of storm events, are occasionally topped by hardgrounds. Hardgrounds provide well-defined boundaries useful for delineating correlative/bounding surfaces, identified here with sequence boundaries (3rd order cycles). Maximum flooding surfaces characterized by richly fossiliferous marly wackestones provide additional correlative horizons. Within these sequences, subordinate cycles can be tentatively distinguished, some of them may represent parasequences. The stratigraphical significance of correlative surfaces and sequences is tested by their fossil content, and these surfaces can be used for regional correlations with neighbouring basin.

Opis:

The purpose of the research is to establish the total number of ponds in Ukraine and to analyse the territorial distribution in the administrative areas, as well as in the river basin districts, as the main hydrographic units of water management. Cadastral data of the State Agency of Water Resources of Ukraine regional offices as of 2019 was used in the research (as to Crimea, Donetsk and Luhansk regions we applied the data as of 2014). According the researches there are 50,793 ponds in Ukraine with a total water table area of 2,92899 ha and the volume of 3,969.4 mln m³ of water in 2019. The quantitative distribution of ponds across Ukraine is unequal. Most of them are concentrated in the central part of the country (10.5% of the total number of ponds in the country are in Vinnytsia region). Least of them are in Luhansk region (0.7%). Almost half of the ponds are located in the Dnieper River Basin (48.5%). The lowest quantity of ponds is in the Black Sea Basin (1.2%). The regulation of river basins districts (the rivers of the Sea of Azov, Crimea and Black Sea Basins) reaches 0.71–0.77. As of 2019, 28% of the ponds are rented out. In order to identify the real status of the ponds (both quantitative and qualitative), their recreational role, the environmental impact and the regulation of the hydrographic network in Ukraine, it is necessary to increase the attention to ponds monitoring.

The paper analyses results of measurements of precipitation amounts in the Widawa River basin in the multi-year period 1956-2012. Analysed were annual, monthly and daily precipitation totals and the numbers of days with precipitation in a year and in a month. Trends of changes were determined and extreme monthly and daily precipitation totals were analysed. Annual precipitation totals over the analysed multi-year period were very strongly diversified. Despite a considerable spread of results, the distribution in time did not reveal any clear tendency of changes, the trend line was almost horizontal. The number of days in a year with precipitation revealed an obvious decreasing trend, particularly within the fraction of days with precipitation <1mm. Average daily precipitation obtained from the ratio of annual precipitation total and the number of days with precipitation showed a growing tendency. December was the month in which the highest number of days with precipitation was noted during the multi-year period 1956-2012. Considering the fewest number of days with precipitation, similar results were obtained for three months. In May and September the least number of days with precipitation was registered eleven times. Only once a less often mentioned number of days occurred in October. A summary of maximum numbers of days with precipitation occurring over a month revealed a declining trend. The diagram of the least number of days with precipitation in a month also revealed a decreasing tendency.

Opis:

As a result of the increase in the world population and the decrease in agricultural land, the need for food increases every day. Nowadays, breeding studies are carried out to increase the yield of plants to get more products from the same area. Furthermore, controlled production areas are created by optimizing climatic conditions and the continuity of production is ensured. It is called greenhouse, where production can be carried out throughout the year and the indoor temperature and humidity conditions can be controlled. Nowadays, greenhouses are now functioning as an industrial enterprise. However, greenhouses need to comply with the principles of quality production, efficient income growth and physical environmental protection. Almost all of the plant production in greenhouses in Turkey is done in the Mediterranean region, but in the Southeastern Anatolia Region, it is done in a very limited greenhouse area. The increase of protected agricultural areas in the Mediterranean region and the fact that the production volume cannot reach a certain limit makes it necessary to investigate alternative protected production areas. In this study, climate conditions of Antalya province and climate data of four provinces of the Lower Euphrates basin are compared with each other and statistically compared. As a result of, differences have been found between Antalya province and the provinces in the Lower Euphrates basin in terms of minimum, maximum, and average temperatures. However, there is no difference between the provinces in the basin except for Gaziantep in terms of climatic conditions. Therefore, it has been determined that Gaziantep province is not suitable for greenhouse cultivation. However, it has been concluded that if greenhouse cultivation is performed in this province, it is appropriate to perform cultivation in the areas where alternative energy sources can be used. It has been concluded that in the case that heating costs are reduced using alternative energy sources, Şanlıurfa and Kilis provinces are climatologically suitable for greenhouse cultivation and Adıyaman province is partially suitable for it.

Opis:

Geological studies of the Polish coal basins - namely the Upper Silesian Basin, the Lower Silesian Basin and the Lublin Basin - are diverse due to the differences in the extent of exploration and coal mining activities, as well as the complicated political history of each basin. This paper presents a review of the most important geological works performed after World War II on the territory of Poland. The studies conducted by the Polish Geological Institute (PGI) were of critical importance, especially those which were concentrated on the geology and stratigraphy of Carboniferous strata. It should be emphasized that the PGI made a great contribution to the discovery and subsequent evaluation of coal resources in the Lublin Coal Basin. Equally important are exploration endeavors and coal resource evaluation conducted by the PGI in the other two Polish coal basins. In addition, the PGI initiated and performed investigations of coalbed methane.

Opis:

We present fifteen new K/Ar ages on amphibole phenocrysts of Neogene volcaniclastic rocks from the Styrian Basin, Austria. The westernmost sub-basin of the Pannonian Basin is the Styrian Basin, which hosts a large number of phreatomagmatic tuff occurrences beside Middle Miocene shield volcanoes and Pliocene effusive alkaline volcanic rocks. The investigated tuffs contain the well-known mantle xenoliths and frequent amphibole and pyroxene phenocrysts. The new K/Ar ages indicate that the Late Miocene phreatomagmatic volcanism started in Pontian (7.51 Ma) and ended in Romanian (2.73 Ma) times. The complete interval of the youngest volcanism in the Styrian Basin covers 5.8 Ma, similar to the volcanism of the western part of the Pannonian Basin and the Nógrád/Novohrad area (West Carpathians). The dated volcanic occurrences display NNW–SSE oriented arrays which are approximately parallel to the Auersbach basinal high zone. The new data indicate that the Late Miocene to Pliocene volcanism of the Styrian Basin is synchronous with the onset of a regional compressional event and eastward tilting of the Styrian basin fill.

Opis:

Over the last few years, global temperature has increased rapidly and continuously at around 0.2 °C per decade. Climate change is expected to have considerable impacts on natural resource systems, which, in turn, can lead to instability and conflict, displacement of people and changes in occupancy and migration patterns. Rise in atmospheric temperature due to climate change will lead to loss of glaciers in the Himalayas, which, in turn, may reduce water availability in the rivers of Indus – Ganga plains, especially in dry seasons. The response of hydrological systems, erosion processes and sedimentation in the Himalayan region could alter significantly due to climate change. During the twentieth century, majority of the Himalayan glaciers have shown recession in their frontal parts, besides thinning of the ice mass. Retreat in glaciers can destabilize surrounding slopes and may give rise to catastrophic landslides and floods. The melting of ice is changing the hydrological cycles and is also affecting the ocean currents. Many of India’s coastal aquifers are already experiencing salinity ingress including Saurashtra coast in Gujarat and Minjur aquifer in Tamil Nadu. Increasing frequency and intensity of droughts in the catchment area will lead to more serious and frequent salt-water intrusion in the estuary and thus can deteriorate surface and groundwater quality and agricultural productivity. A warmer climate will change the patterns of hydrological cycle, which, in turn, can alter the intensity and timing of rainfall. Mahi, Pennar, Sabarmati and Tapi rivers will face water shortage conditions in response to climate change. River basins belonging to Godavari, Brahmani and Mahanadi may not face water shortages, but severity of flood shall increase in these areas. In future, there will be a net reduction of groundwater recharge and greater summer soil moisture deficits because higher temperature can shorten the duration of recharge seasons. Production of rice, maize and wheat in the past few decades has declined in many parts of Asia due to water shortage. Linking the concept of sustainable development to climate change can provide a deep insight into the proper methods of long term societal responses to global environmental change.

Opis:

In order to properly design a shaft it is necessary to acquire full information about the rock mass in the exploration area. It is especially crucial in the case of the deposit of an unusual vertical intrusion shape, occurring at a great depth. Such a situation implies that the shaft lining design must take into consideration not only the geomechanical properties of the rock mass but also the virgin stresses (often having significant values). In this paper, the methodology of the shaft lining and shaft station lining design for a deep shaft is presented based on the Victoria Mine located in Canada. Taking into consideration the geological structure as well as the results of the laboratory tests, the properties of the rock mass were derived. Next, the numerical calculation was performed based on the elasto-plastic model of the rock mass. The numerical analysis consisted of simulation of the multistage technology of the shaft excavation and lining execution. This allowed to estimate the forces in rock bolts of the temporary ground support as well as stresses in the final concrete lining of the shaft.
Do procesu projektowania obudów wyrobisk udostępniających złoże wymagane jest posiadanie pełnych informacji o górotworze rejonu złożowego. Jest to szczególnie ważne w przypadku złoża zalegającego na dużej głębokości, o nietypowym kształcie pionowej inkluzji, gdzie dobór obudowy musi uwzględniać nie tylko własności geomechaniczne masywu skalnego, ale również naprężenia tektoniczne (pierwotne), niekiedy o znacznych wartościach. W niniejszym artykule zaprezentowano metodykę doboru obudowy szybu oraz obudowy wlotów dla głębokiego szybu na przykładzie Kopalni Victoria w Kanadzie. W oparciu o informacje o budowie geologicznej oraz bazując na wynikach badań prowadzonych dla potrzeb rozpoznania złoża określono własności masywu skalnego. Na ich podstawie opracowano numeryczny, sprężysto-plastyczny model górotworu. W analizie numerycznej, wykorzystującej możliwości posiadanego oprogramowania zasymulowano zgodnie z założoną technologią wieloetapowe wykonywanie wyrobiska szybowego wraz z jego obudową, co pozwoliło na oszacowanie wielkości sił w kotwach obudowy wstępnej szybu oraz wlotów podszybi, jak również naprężeń w betonie obudowy ostatecznej szybu.

Opis:

The prioritisation of catchments, particularly in the context of catchment plans and management programmes, is part of water resources development. In fact, morphometric analysis assisted by geospatial technology is carried out by prioritising sub-catchments according to their natural resource availability characteristics. Information on the geomorphology and erosion factors of the study area is used in the area in the preparation of local models of ungauged sub-catchments, which otherwise lack an adequate hydrological database. The objective of this paper is to use geographic information systems (GISs) in morphometric analysis to prioritise sub-catchments of the Soungrougrou (a tributary of the Casamance River). In this respect, the integrated methodology involving morphometric aspects from geospatial technology is used. To carry out the geospatial research, basic mathematical equations used in a GIS environment were used to measure a series of aspects of hydrology such as flow length, flow length ratio, bifurcation ratio, drainage density, drainage texture, flow frequency, elongation rate, circularity ratio, form factor, relief and relief ratio. The results divided the whole catchment into three priority areas, namely high, medium and low. The results are relevant for establishing soil and water conservation plans in the Soungrougrou basin, as well as adequate groundwater production and management. The high category (sub-basins 6, 8, 14, 17 and 18) is subject to maximum soil erosion, which requires immediate intervention to avoid possible natural hazards.

The problem of locating mine tremors using P-wave arrival times is revisited in the paper. A multidimensional, global, non-linear, constrained optimization method is used as a minimization algorithm for tremor location.In order to see the general properties of the minimized function a few images showing its basins of attractions have been constructed. These pictures enable us to choose efficient algorithms needed to solve location problems. The classical genetic algorithm, pure random search and the most efficient multistart algorithm have been tested. Local minimization methods should be introduced to the location procedure to increase the efficiency of tremor location.

Opis:

A summary of known crinoid taxa in the Polish part of the Triassic Germanic Basin, including their presence elsewhere, is documented. At present, 13 taxa and 3 ecophenotypes of crinoids have been recorded from that area, only one of them being endemic. In the Lower Muschelkalk and lower part of theMiddleMuschelkalk, taxa widespread both in the Tethys and Germanic Basin, or Tethyan taxa, dominate. In the Upper Muschelkalk crinoids are very rare in Poland, being represented by Encrinus liliiformis and Holocrinus sp. Many of the species occurring in the central part of the Germanic Basin in the Upper Muschelkalk have not been recorded in the eastern part of the basin. The degree of endemism of the crinoid fauna in theMuschelkalk is markedly lower than the degree of endemism of the rest of the benthonic macrofauna. This probably resulted from huge number of crinoids forming "crinoid gardens" that produced large number of larvae, increasing the chances of successful geographical expansion of crinoids.

Three types of mollusc communities can be distinguished. The oldest is dominated by freshwater taxa and corresponds to calcareous gyttja of Eemian age. The next two assemblages contain only snails typical of loess. The first of these indicates a cold and dry climate and open environment of arctic steppe type, with rapid accumulation of loess; the second assemblage represents a cold and humid climate and a relatively moist, open environment of tundra type.

Opis:

The Laslau Mare field is a brown gas field in the Transylvanian Basin. The field was developed in the 1970s and the production consists of more than 99% methane gas and low WGR (average of 0.03 m3/kscm). Current reservoir pressures are at a less than a third of initial values. As in any mature field with increasing water production and reservoir pressure depletion, several degrees of formation damage and tubular obstructions have been observed. Mud invasion, plugged perforation, water blockage and scale precipitation at the near wellbore region are factors impairing wells to produce at potential. Adding to the above the fact, the reservoir is water sensitive (low reservoir pressures and water wet reservoir). Severe constraints on production were seen when performing any sort of operation requiring the use of water based fluids, as severe losses occur. These procedures have always given post-job challenges to production engineers. Skin induced by mud or liquid losses is highly affecting wells post job performance. Long recovery times have been observed following workovers’ operations in Laslau Mare (0.5 to 2.5 years recovery for workovers and one to three months for wash treatments). Perforation and re-perforation operations are one of the best way to overcome the formation damage, bypass the invaded zones and open new production zones. Historically, perforation was done with casing guns in overbalanced condition. This practice induces immediately a skin created by fluids losses and prolong the flow back periods making the stimulation much less effective. Another methodology is to run through tubing guns and perforate in underbalanced conditions with smaller guns being limited by the completion size. In the latter case, the perforation performance are much less than the casing gun ones. In both cases, the full potential of the well is not achieved. A newer methodology is introducing re-perforation/perforation with casing guns in underbalanced, dry conditions, within snubbing operations. The methodology allows instantaneous gain of production and maximizes well recovery factor in the long term. Two pilot operations were executed with very good results and promising opportunities arise for candidate wells in the field.

Opis:

The study aimed to evaluate the spatiotemporal variation in the physico-chemical and bacteriological quality of Oued Inaouène water in relation to urban discharges that remain the main sources of pollution in the Inaouene basin. During the period from May 2019 to March 2020, seven stations were sampled, six of which are spread along the Inaouène Oued in addition to one reference station that is less affected by urban pollution. The indicators used were: temperature, pH, electrical conductivity (EC), turbidity and dissolved oxygen (OD), biological oxygen demand (BOD5), chemical oxygen demand (COD), Kjeldahl nitrogen (TKN), E coli, IE and TC. The quality data obtained were analysed using multivariate statistical methods (the CPA) and the correlation matrix. The results showed that with the exception of the OT station located upstream of urban discharges, the majority of stations downstream of urban discharges have poor quality during both wet and dry seasons, according to the Moroccan standards.

The Vistula is the largest river in Poland, which flows from the south to the north. Its mouth is on the Baltic Sea. As for hydrography the Vistula is divided into three parts: Upper – from its sources to the mouth of the River San, Middle – up to the tributary Narew River, and the Lower – up to its mouth on the sea. This article covers the Vistula and its basin management plans starting from the interwar period up to the present day. The location of the Vistula and its basin as well as land cover are described. The division of Poland into river basin districts and water regions accompanied by a description of administrative division of the country are described. Climatic conditions of Poland including precipitation and air temperatures are presented. Basic hydrological data of the Vistula and its basin is given. Parts of the Vistula basin, which are included in the Program of Natura 2000 are mentioned. Brief information concerning existing, more important hydraulic and hydroenergy structures in the main Vistula channel as well as on its tributaries are described.
Wisła jest największą polską rzeką, która płynie z południa na północ, a jej ujście znajduje się w Morzu Bałtyckim. Pod względem hydrograficznym Wisła dzieli się na trzy części: górną – od źródeł do ujścia Sanu, środkową – do dopływu Narwi i dolną - największą polską rzeką, która płynie z południa na północ, a jej ujście znajduje się w Morzu Bałtyckim. W artykule przedstawiono plany zagospodarowania Wisły i jej dorzecza, poczynając od okresu międzywojennego zą do chwili obecznej.

Opis:

The Hamira Member (Bathonian) of the Jaisalmer Formation records the first marine transgression within the Jaisalmer Basin. It also contains the ichnogenus Asteriacites von Schlotheim, 1820, as documented here for the first time. This was used to refine interpretations of the palaeoenvironment. Crowded ophiuroid resting traces, Asteriacites lumbricalis, occur in a silty limestone unit 1 m thick. This is preceded by a monospecific assemblage of Diplocraterion parallelum towards the base of this unit, while towards the top there is an assemblage, comprising Gyrochorte comosa, Protovirgularia rugosa, Rhizocorallium commune and Rosselia socialis. Colonisation by the Asteriacites trace makers occurred in a shallow-water, marginal-marine, normal-salinity, fully oxygenated, high-energy setting with steady rates of sedimentation. From an ichnological perspective, the sequence investigated shows a shift in environmental conditions from the middle shoreface to the off shore transition zone. Addressing the Asteriacites/Heliophycus nomenclatorial dilemma, Knaust (2012) suggested that the generic designation Asteriacites should be retained. His view was found to be appropriate and supported to avoid further confusion.

Opis:

Palaeomagnetic results are presented for 205 samples of cores from the Książ Wielkopolski IG-2, Woźniki K1 and Patoka 1 wells, drilled in the Polish part of Germanic Basin. The magnetic polarity stratigraphy is based on the inclination of the characteristic remanent magnetization, isolated in 60% of the total samples and found to be in general agreement with the expected Late Triassic inclination at the sampling sites. A total of 22 magnetozones from the integration of the three records correspond to about 25% of the published polarity zones for the Upper Triassic sediments that were combined in the worldwide composite polarity-time scale. The magne- tic polarity pattern, defined for the Schilfsanstein, fits very well with the one defined in the Tethys area for the upper part of the Julian sub-stage. According to the magnetostratigraphic data, the uppermost part of the Upper Gypsum Beds (equivalent to the Ozimek Member of the redefined Grabowa Formation) and the lowermost part of the Patoka Member, containing the Krasiejów bone-breccia horizon, can be correlated with the latest Tuvalian (~228.5 Ma) or with the middle part of Lacian (~225 Ma). However, if the “Long-Tuvalian” option for the Late Triassic Time Scale is taken into consideration, the parts of these substages mentioned above should be correlated with ~221.5 Ma and ~218.5 Ma, respectively.

Opis:

Dnieprovsky lignite basin, situated in central part of Ukraine over the area of about 400 km2, contains more than 150 deposits. About 55 deposits have industrial significance. Their reserves are 2.4 billion tons. Seams and lenses of coaly clays and sands overlay the coal series and occur between coal packets. The coaly clays are classified into this category because their ash content exceeds 40%. Our investigations show that coaly rocks are similar to lignite in composition and properties. They have ash content from 40% up to 60%, the same elementary composition of organic matter. As well as bitumen and humic acids yield. It has been established that coaly rocks can be used as energy and chemical raw material, the basis of good carbon sorbents with high adsorptional capacitance. The recommendation of coaly rocks for mining and processing is difficult because of lack of information in geological reports on their quantity, composition and properties, as they are considered as host rocks but not as mineral resources. If the usable coal limit was accepted at 50% of ash content, the coal reserves of some deposits would have increased 1.5-2 times.

Opis:

For many years the media have presented the rainforest as a fascinating and exotic place, abundant in various species of plants and animals, the home of people decorated with feathers or holding spears. Picturebooks are no exception. This article presents the ways a popular image of the Amazon forest is produced in picturebooks for young readers in English-speaking industrialised societies. The analysis shows that shaping knowledge about the tropical forest is based on stereotypes about the “untouched pristine forest” populated by “wild indigenous people” – a notion that is spurious. Some of these books undertake the subject of indigenous knowledge or the loss of cultural identity. However the presentation of these issues often lacks deeper dimensions. The exoticisation of rainforest inhabitants as well as the forest itself may have a negative impact on young readers’ understanding of the cultural diversity of the Amazon, as well as their understanding of the complexity of indigenous peoples’ lives.

The fish fossils illustrating a large-sized specimen originate from the South Racoş coal open pit (Racoşu de Sus, Covasna County), in the so-called “Formation with Limnocardium” (Dacian, Lower Pliocene). Comparisons with osteological material of recent pikes originating from various localities in Romania are presented. The associated mollusc fauna known from the formation that yielded the pike remains suggests the presence of a lake with a stratified water column in the Baraolt sub-basin.

Opis:

Among Evolutionary Multiobjective Optimization Algorithms (EMOA) there are many which find only Paretooptimal solutions. These may not be enough in case of multimodal problems and non-connected Pareto fronts, where more information about the shape of the landscape is required. We propose a Multiobjective Clustered Evolutionary Strategy (MCES) which combines a hierarchic genetic algorithm consisting of multiple populations with EMOA rank selection. In the next stage, the genetic sample is clustered to recognize regions with high density of individuals. These regions are occupied by solutions from the neighborhood of the Pareto set. We discuss genetic algorithms with heuristic and the concept of well-tuning which allows for theoretical verification of the presented strategy. Numerical results begin with one example of clustering in a single-objective benchmark problem. Afterwards, we give an illustration of the EMOA rank selection in a simple two-criteria minimization problem and provide results of the simulation of MCES for multimodal, multi-connected example. The strategy copes with multimodal problems without losing local solutions and gives better insight into the shape of the evolutionary landscape. What is more, the stability of solutions in MCES may be analyzed analytically.

The drought ranked first in terms the natural hazard characteristics and impacts followed by tropical cyclones, regional floods, earthquakes, and volcanoes. Drought monitoring is an important aspect of drought risk management and the assessment of drought is usually done through using various drought indices. The western region in Algeria is the most affected by the drought since the middle of the 70s.The current research focuses on the analysis and comparison of four meteorological drought indices (standardized precipitation index – SPI, percent of normal index – PN, decile index – DI, and rainfall anomaly index – RAI) in the Tafna basin for different time scales (annual, seasonal, and monthly) during 1979–2011. The results showed that the SPI and DI have similar frequencies for dry and wet categories. The RAI and PN were able to detect more drought categories. Meanwhile, all indices have strong positive correlations between each other, especially with Spearman correlation tests (0.99; 1.0), the meteorological drought indices almost showed consistent and similar results in the study area. It was determined in 1982 as the driest year and 2008 as the wettest year in the period of the study. The analysis of the trend was based on the test of Mann–Kendall (MK), a positive trend of the indices were detected on a monthly scale, this increasing of indices trend represent the increasing of the wet categories which explains the increasing trend of the rainfall in the last 2000s. These results overview of the understanding of drought trends in the region is crucial for making strategies and assist in decision making for water resources management and reducing vulnerability to drought.

Opis:

Palynostratigraphic studies of the Carboniferous strata of the Szczawno and Wałbrzych formations, outcropping in the vicinity of Wałbrzych in the northern part of the Intra-Sudetic Basin, are reported. Rocks of the Szczawno Formation in a section near Konradów had earlier been assigned to the Upper Visean, while rocks of the Wałbrzych Formation in the Biały Kamień section were included to the Lower Namurian [the Stenozonotriletes triangulus–Rotaspora knoxi (TK) Miospore Zone]. This study describes abundant palynological material with many taxonomically diverse miospore assemblages from these rocks, allowing precise palynostratigraphic conclusions. These showed that the rocks of the Szczawno Formation studied should be referred to the lower part of the Serpukhovian [Verrucosisporites morulatus (Vm) Subzone], correlated with the lowest Namurian, while rocks of the Wałbrzych Formation from Biały Kamień belong to the Lower Bashkirian [Lycospora subtriquetra–Cirratriradites rarus (SR) Subzone], correlated with the Upper Namurian A. These results indicate that the rocks from both sections studied are younger than they were earlier believed. This revises the age of the Szczawno and Wałbrzych formations in the northern part of the Intra-Sudetic Basin which belong to four miospore zones, from Vm to SR, corresponding to the Serpukhovian and lowermost Bashkirian (Namurian A corresponding to the Pendleian to Alportian of British chronostratigraphy).

Opis:

To establish the brine chemistry associated with the evaporites in the Pennsylvanian Paradox Basin of southeastern Utah and southwestern Colorado (USA), the composition of primary fluid inclusions was determined for sedimentary halite from two drill cores, one near the central part of the basin (Shafer Dome No. 1) and one from a more marginal location of the basin (Gibson Dome No. 1). Chemical analysis of halite fluid inclusions was done on six samples from three different evaporite cycles of the Paradox Formation; cycle 10 in the Shafer Dome core and cycles 6 and 18 from the Gibson Dome core. The inclusions that range in size from 2 to 80 microns across, were analyzed using the Petrychenko method. Large inclusions (40 to 80 microns across) that were used for the chemical analyses contain one fluid phase with a carnallite or sylvite daughter crystal. Also reported in this study are fluid inclusion homogenization temperatures for sylvite or carnallite from primary halite crystals in the Gibson Dome core and in Shafer Dome. The relationship between K+ and Mg2+ in chloride rich inclusions corresponds to their proportion in MgSO4-depleted marine waters concentrated to the stage of carnallite deposition. A correlative relationship was observed between K+2+4-rich to MgSO4-poor compositions that have been proposed by other workers. A transition from MgSO4-rich to MgSO4-poor seawater composition may have occurred between Pennsylvanian and Permian times. This paper presents a possible alternate explanation to those already proposed in the literature, that the Paradox Formation mineralogy resulted from an intermediate seawater composition that records the global transition from MgSO4-rich to MgSO4-poor seawater.

Opis:

The evolution of the Transylvanian Basin during the Early Miocene has been restored from the succession of palaeoenvironments inferred from the sedimentological trend and succession of specific foraminifera assemblages from Lower Miocene Tihău section in northwestern Transylvanian Basin. Planktonic foraminifera suggest a Burdigalian age and recorded sea-level changes, climatic and productivity events. Benthic foraminifera offered valuable data on the palaeoenvironmental evolution, with a large-scale progradational (coarsening up) sedimentary succession influenced by regional tectonics. The succession of depositional events include: i) transgressive coarse grained deposits with typical mediterranean assemblages of bivalves in beach environments; ii) the glauconitic facies which can be associated to the maximum flooding surface of the transgression; iii) the sedimentation continued on a narrow shelf influenced by deltas during the highstand; iv) influence of regional tectonics and subsequent filling with turbidites associated to fan deltas.

Opis:

The fourth century saw the beginning of spreading Christianity among Germanic people. The mission of bishop Ulfi las, however, ended in 348 and persecuted Christian Goths fl ed to the territory of the Roman Empire. After the destruction of Gothic kingdoms, the fl eeing Goths were allowed by the Roman emperor Valens to cross the Danube, probably only on condition that they would adopt new faith. Since the emperor himself was an Arian and Arianism preferred theological teaching in the Roman Empire, the Goths, and later other East Germanic tribes, adopted this doctrine instead of Nicene Creed. Germanic people learned only the basic principles of faith and then just continued with their beliefs. Moreover, Jesus was deemed not the only God, but one of many gods. The second part of the study offers a survey of written sources on the Christianity among Germanic tribes in the Carpathian Basin in the sixth century – Rugians, Heruls, Gepids and Lombards. The Rugians led by the king Feletheus (Feva) and his Arian wife Giso dwelt on the left bank of the Danube, opposite the Roman province of Noricum, where at that time St. Severinus preached Christianity, established monasteries, organised defence or evacuation, redeemed captives, procured corn for the starving and healed the sick. Humble and pious Severinus won himself such a reputation that even barbarian kings respected him and listened to his advice and prophecies. The neighbouring Heruls, however, were pagans and sometimes invaded barely defended provinces of Noricum and Pannonia. Though their king received baptism in 528, many of them remained pagans and, according to Procopius, they were the wickedest people in the whole world. The Gepids, like Goths, converted to Arianism. The most signifi cant traces of Gepid Christianity are found in the territory of Pannonia II, especially near the Roman town of Sirmium. Sirmium was one of the most important centres of early Christianity and in the late sixth century, the town having become a seat of Gepid Arian bishop. On the other hand, Lombard Arianism is very problematical. The fi rst mention of their orthodox faith comes from Procopius. Paganism, however, was retained not only by the majority of the tribe, but also by the king and his retinue, even at the time 568 invasion in Italy. Arianism among Lombards probably gained strength only in Italy, where a number of subjugated Gepids accompanied them and where remnants of Arian Goths continued to live. From Alboin to Aripert (altogether 9 rulers) only two kings are mentioned as Arians and only two as Catholics. Though these Germanic tribes adopted Christianity in the Carpathian Basin, they did not stay there long enough to become true Christians. With Slavs and Avars replacing them, the Christianisation of Central Europe had to start from scratch.

Opis:

The genus Leinzia is a typical member of the renowned Artinskian–Wuchiapingian (Permian) endemic bivalve fauna of the Passa Dois Group, Paraná Basin, Brazil. The extraordinary shells of Leinzia, characterized by a rostrum extending from the anterior cardinal margin led certain authors to regard them as bivalved arthropods (Spinicaudata). Due to the unusual morphology and typically poor preservation of the available specimens, the taxonomic position of Leinzia still remains obscure. Leinzia has been variously referred either to the Pterioida, the Crassatelloidea, the Sanguinolitidae, or the Megadesmidae, or to the Pholadomyida. Herein, based on a detailed review of the topotype material and description of newly found specimens of Leinzia from the Serrinha Member, Rio do Rasto Formation, southern Brazil, we shed light on the taxonomic position of this genus. The hinge of the right valve with its large, blunt, anteriorly inclined subumbonal tooth and corresponding socket in the left valve coupled with the absence of true lateral teeth indicate close affinities to Pyramus and Cowperesia. Thus, the data here strongly suggest a Pachydomidae (Edmondioidea) rather than a Crassatelloidea affinity for Leinzia. Conversely, Leinzia differs from all other known Pachydomidae due to its anteriorly rostrate and posteriorly elongated shell. Finally, detailed stratigraphic data indicate that the vertical distribution of Leinzia is constrained to the middle part of the Guadalupian Serrinha Member of the Rio do Rasto Formation.

Opis:

The ancient hydrocarbon seep deposits at the La Elina Ranch, Neuquén Basin, northern Patagonia, Argentina, are the only Mesozoic seep site in South America yielding metazoan fossils. Apart from benthic mollusc shells and worm tubes, they yielded a number of nektonic ammonoids. Four species of ammonoids were identified: Hildaitoides retrocostatus, Hammatoceras ex gr. insigne, Calliphylloceras cf. nilssoni, and Phylloceras sp. The occurrences of three species (H. ex gr. insigne, C. cf. nilssoni, and Phylloceras sp.) probably are fortuitous, while H. retrocostatus might have actually thrived in, or around the seep, as indicated by numerous well-preserved juveniles, in addition to some adult specimens. The bathymetric estimates indicate a depth not greater than 200 m, while the benthic molluscs, typical of hydrocarbon seeps, indicate a much greater depth. It is hypothesized that the deep-water taxa might have occurred in a shallower setting, owing to rising anoxia and/or strong input of continental waters from the eastern and/or southeastern deltaic system. The ammonite assemblage indicates that the seep at La Elina is (Andean) Middle Toarcian, probably Chilensis Zone, in age.

Opis:

Three-dimensional, structural and parametric numerical modelling was applied to unravel the unconventional hydrocarbon potential of a W-dipping, Lower Palaeozoic mudrock succession, which subcrops for some 700 km in the Baltic, Podlasie and Lublin basins across the SW margin of East European Craton in Poland. Input data comprised structural and thickness maps of Ordovician and Silurian strata and the results of thermal maturity (mean vitrinite-equivalent reflectance, % Ro) and total organic carbon (TOC, % wt.) modelling. A new, spatial interpretation of vitrinite-reflectance variability indicates that the regional, W-increasing thermal maturity pattern breaks into a series of domains, bounded by abrupt maturity variations. In total, 14 tectono-thermal domains were recognised and their boundaries traced to known and inferred faults, mostly of NW‒SE and NE‒SW orientations. On the basis of a combination of thermal maturity and total organic carbon levels (0.6% > Ro<2.4%, and TOC >1.5% wt.), good-quality, unconventional reservoirs can be expected in the Sasino Formation (Caradoc) and Jantar Formation (early Llandovery) in the central and western Baltic Basin. The Jantar Formation also is likely to be prospective in the western Podlasie Basin. Marginal-quality reservoirs may occur in the Sasino and Jantar formations within the Podlasie and Lublin basins and in the Pasłęk Formation (late Llandovery) across all basins. Poor- to moderate-quality, unconventional reservoirs could be present in the Pelplin Formation (Wenlock) in the Lublin and southern Podlasie basins. In spite of a considerable hydrocarbon loss during multiphase basin inversion, the Ordovician and Silurian mudrocks still contain huge quantities of dispersed gas. Successful exploitation of it would require the adoption of advanced fracking methods.Lower Palaeozoic, shale gas, shale oil, Baltic Basin, Lublin-Podlasie Basin, total organic carbon, thermal maturity, structural-parametric model.

Opis:

The assemblage of rare fish microremains of chondrichthyans and actinopterygians from Upper Permian deposits in Karpénai Quarry in northern Lithuania is described in detail for the first time. The deposits are characterized as reflecting a rapid phase of deposition of the Zechstein Limestone, interpreted as on a shallow shelf above storm-wave base in a proximal part of the Polish-Lithuanian Zechstein Basin. The actinopterygian microremains are represented by various teeth and a few scales from mostly palaeonisciforms and pycnodontiforms. The chondrichthyans are represented by various eusela- chian-type scales and a tooth of ?Helodus sp. The low abundance and low species diversity of the fossil assemblages studied may be due to arid palaeoenvironments that caused locally restricted conditions at this palaeogeographical location.

Opis:

Analysis of previously available stratigraphic data coupled with the re-interpretation of seismic profiles calibrated by boreholes has allowed the construction of a new tectonic model of evolution of the Gdów “embayment” – a tectonic re-entrant located along the Carpathian front east of Kraków (southern Poland). This model shows that the main phase of localized fault-controlled subsidence took place in the Early Badenian and was associated with deposition of the locally overthickened Skawina Formation. Also, deposition of evaporites of the Wieliczka Formation seems to have been tectonically controlled by local basement faulting. Supra-evaporitic siliciclastic deposits have developed as a result of overall north-directed sediment progradation from the eroded Carpathian belt towards the Carpathian Foredeep. During the final stages of development of the Carpathian fold-and-thrust wedge the previously subsiding Gdów “embayment” area was uplifted and basement faults were reactivated either as reverse faults or as low angle thrust faults. Along the leading edge of this inverted structure a triangle zone developed, with backthrusting along the evaporitic level. As a result, overthickened evaporites, formed in local tectonically-controlled depressions within the area of the Gdów “embayment” area have been strongly folded and internally deformed.

The Orava-Nowy Targ Basin is an intramontane depression located at the border of the Inner and Outer Carpathians. It is filled mostly with fine-grained terrestrial and fresh-water deposits of Neogene and Quaternary age, which record the structural evolution and denudation processes of the surrounding regions: Orava, Podhale, and the Tatra Mts. The Orava-Nowy Targ Basin fill was studied in the Oravica River section, which reveals 90 m thick Neogene deposits and allows observation of their lateral diversity. Fifteen lithofacies and seven facies associations distinguished here document the depositional evolution of the basin fill, starting from hill-slope debris flow through silt turbidite-bearing lake, to flood-dominated fluvial plain, swamp and alluvial fan deposits, as well as a pyroclastic event. The palaeorelief was low during deposition and the Orava-Nowy Targ Basin could have spread significantly more to the south.

Opis:

Evolution of the Pomeranian Basin (NW Poland) dur ing the Devonian saw the development of a characteristic siliciclastic and mixed siliciclastic-carbonate marginal marine-to-open marine carbonate sedimentary succession. This was controlled via proximity of the land areas representing uplifted parts of the East European Craton (EEC): the Fennoscandian High extending in the north, and the Mazury–Belarus High, situated in the east. The depositional history of the Pomeranian Basin began not earlier than at the end of the Emsian or possibly in the Eifelian, after a long break spanning the Lochkovian, Pragian and much of the Emsian when the area was subjected to erosion. Sedimentation started in the north eastern part with marginal-marine clastic deposits with local evaporites which are dated as uppermost Emsian?–Eifelian, passing upwards into lower–middle Givetian marginal-marine siliciclastic and carbon ate de posits; these are followed by upper Givetian marginal-marine siliciclastic rocks. In the south western part of the area, the Devonian succession started with marginal-marine carbonates and siliciclastics which belong to the upper most Emsian?–Eifelian, followed by lower and middle Givetian carbonates, passing upwards into upper Givetian marginal-marine siliciclastics. During the Late Devonian the Pomeranian Basin underwent evolution from a marginal-marine in the earliest Frasnian, through carbonate ramp or platform/shelf basin settings during the rest of the Frasnian and early Famennian, up to a reappearance of shallow subtidal and marginal-marine environments in late Famennian time. At the end of the Famennian an open shelf environment became prevalent almost over the whole area and continued up to the Mid Tournaisian. The lateral relation ships of the lithofacies during the Givetian, Frasnian and Famennian are portrayed on 11 maps, showing relatively short time-intervals, selected to depict the most sigificant environmental changes.

As “Wolfsberg” did not have the dimensions of the nearby prehistoric fortifications at Sântana and Corneşti, the site was not targeted by archaeological investigations and it has only been occasionally mentioned in the secondary literature so far. During the year 2014 a team of researchers have started the investigations with the site’s topographic survey, followed by a systematic ground survey, geophysical measurements, as well as aerial photographs. Three years later, a small test trench was excavated in order to attempt dating the Middle Bronze Age tell in terms of the absolute chronology

Opis:

The Mšeno-Roudnice Coal Basin is an eastern part of the Central Bohemian Carboniferous Coal Basins. The total thickness of the Carboniferous sediments is ranging from several tens of metres in the south up to nearly 1 km in the basin centre. The basin was explored by nearly 55 deep boreholes with the aim to explore coal reserves. The seismic exploration in the basin has been carried out, too. Fossil stream pattern was reconstructed, of which rivers eroded the upper part of the Slaný Formation sediments during the intra-Stephanian hiatus between the Slaný and Líně Formation (Stephanian B/C). The project could have been realized due to some drilling close to seismic profiles, and also at least due to locally favourable seismological conditions. The results allowed to decipher the anomalous depositional structure of the Slaný and Líně formations that was difficult to be defined earlier. The results showed that some tectonic movements occurred towards the end of the Stephanian B which resulted in giving rise of erosional activity of ancient streams.

Opis:

Faced with the challenges of sustainable groundwater resource management in the arid zone, the identification of reserves and their monitoring have become vital. This paper aims to identify the Turonian aquifer in the Cretaceous Béchar basin, and calculate its transmissivity, permeability and storage coefficient, as well as its evolution over time. This Turonian aquifer is characterized by marine limestones (gentle dip shelters 45° to the North and 5° to 10° to the South). Pumping tests revealed a transmissivity T of 10^–4 to 10^–2 m²·s^–1, a permeability K of 10^–6 to 10^–4 m·s^–1 and a storage coefficient S of approximately 10^–3. Two piezometric campaigns, carried out between (1976–2018), show a converging and constant flow direction from the North–East to the South–West and from the North–West to the South–East towards the outlet of the basin. Decreased values were observed in the North and South–West borders due to isopiezometric lines. However, this water table is not in a stationary state, it shows seasonal and interannual fluctuations in relation to the variable rainfall and the exploitation rate. In terms of facies, the projection of the two hydrochemical campaigns, during 1976 and 2018 on the Piper diagram, did not show any significant evolution, they are concentrated in the chlorinated and sulphated calcium and magnesium facies.

Opis:

The Badenian/Sarmatian boundary in the Central Paratethys has been traditionally identified by the faunal turnover recording an important environmental change possibly controlled by the change from marine to brackish conditions. The strata below the Badenian/Sarmatian boundary in the northern Carpathian Foredeep are included into the Pecten beds, and those above it into the Syndesmya beds. Foraminiferal study of the Babczyn 2 borehole which is one of the crucial sections in the northern Carpathian Foredeep, well-known for the depositional age of rhyolite tuff within the Pecten beds dated by Śliwiński et al. (2012) at 13.06 ±0.11 Ma, indicated that in fact the boundary occurs within the Syndesmya beds. This conclusion is based upon the rapid change from a stenohaline foraminiferal fauna to a euryhaline one, and the appearance of the species Anomalinoides dividens, the taxon regarded as the marker for the Sarmatian. In the Babczyn 2 and Cieszanów 1 (located ~2.5 km basinward of Babczyn 2) boreholes, Anomalinoides dividens appears 3.1–3.8 m above the replacement of stenohaline by euryhaline foraminifers. The calcareous nannoplankton study shows that the upper Badenian and the lower Sarmatian strata in the studied sections represent the NN6, undivided NN6-NN7, and NN7 zones.

Opis:

The micromorphic brachiopods have been found in the Miocene silty deposits of Kamienica Nawojowska in the intra-Carpathian Nowy Sącz Basin, southern Poland. The assemblage consists of two species Argyrotheca cuneata (Risso, 1826) and A. cordata (Risso, 1826). The presence of stenohaline brachiopods indicatesMiddleMiocene (?Badenian) age of the sediment. The preliminary sedimentological and palaeoecological analysis suggests that brachiopods and associated faunamight be transported basinward from a shallower setting.

Opis:

The Polish part of the Central European Variscan foreland includes several regional units that differ in crustal structure and are characteried by distinct Devonian to Carboniferous subsidence and depositional histories. These units responded differently to palaeostress changes along the south ernmargin of the Old Red Continent. During the Devonian to Namurian A, areas located to the south-west of the Teisseyre-Tornquist Zone (TTZ), including the Upper Silesian Coal Basin, Małopolska and Łysogóry-Radom blocks, were influ nced by stress fields similar to those in the west ward adjacent Rheno-Hercynian Zone, whilst the Lublin Basin, located to the north-east of the TTZ, shows a similar development to the Pripyat-Dniepr-Donets rift system. After the Namurian A, the entire southern Pol ish foreland started to respond in a more consistent way to the build-up of synorogenic compressional stresses, implying a more uniform development of the stress field. During the Namurian B to early Westphalian D, the Polish foreland was dominated by north-directed compressional stresses emanating from the Southeastern Variscan Belt. During the late Westphalian and early Stephanian, the entire foreland under went compressional deformation and concomitant basin in version under the influence of stresses propagating from the Moravian-Silesian Foldand-Thrust Belt. In the Polish foreland, the development of Devonian-Carbon if erous basins, as well as the architecture of Variscan structures, clearly reflect the reactivation of preexisting crustal discontinuities, including specifically the TTZ, but also other major geophysically defined crustal bound aries. In general, thick-skinned tectonics controlled by the inherited structural grain of the basement prevailed, whereas structural decoup ling, resulting in the development of minor thrusts and reverse faulting, was of local significance only. The distinct structural-depositional development of the Pomerania region reflects its distal location with respect to the evolving orogen. Orogenic compression influenced this area only indirectly, with the TTZ acting as a guide for the transmission of transtensional and transpressional stresses.

Opis:

This study estimates the reservoir properties of the Carboniferous deposits in the southeastern part of the Lublin Basin based on diagenetic and sequence stratigraphic patterns. Depositional sequences distinguished represent the following environments/processes: shallow clay and carbonate shelves, deltaic, fluvial, and hyperconcentrated flow while para-sequences (cyclothems), maximum regression-initial transgression surfaces (T), maximum flooding surfaces (MFS) and also lowstand (LST), transgressive (TST) and highstand (HST) systems tracts have been recognised. Sequences recognized may be linked to the global stratigraphic division of the Carboniferous, thus providing a time framework and environmental context for petrographic and petrophysical examinations. The reservoir properties were found to be clearly controlled by depositional environment, diagenetic history and burial. The best properties were recognized in sandstone lithosomes formed in braided, meandering and anastomosed fluvial channels and hyperconcentrated flows which fill the incised valleys and belong to the LST. They are characterized by good porosity reaching up to 15.1%. The TST and HST deposits are represented chiefly by claystones, mudstones and limestones that formed in a shallow shelf and deltaic environment, being sealing intervals. The diagenetic history of sandstones comprises eo-, meso- and telodiagenetic phases. The major processes acting during the first of these were mechanical compaction, dissolution of mineral grains, formation of predominantly quartz overgrowths around the quartz grains, and crysialiizaton of kaolinite. During mesodiagenesis, cementation with quartz, kaolinite and carbonates continued along with the formation of dickite and fibrous illite; moreover, mineral grains were dissolved and chemical compaction set in. The effects of telodiagenetic processes were feldspar dissolution and precipitation of kaolinite. During diagenesis the maximum temperature affecting the Carboniferous deposits was ~120°C. Compaction and cementation were the main factors responsible for the reduction of porosity by approximately 55 and 38%, respectively. One of the major diagenetic processes was dissolution resulting in the formation of secondary porosity. The Serpukhovian and Bashkirian sandstones from sequence 11 show good reservoir potential, while those from sequences 6, 9, 10, 12-14 only fair potential.

Opis:

Cretaceous limestones from the basement of the Neogene Mut Basin are strongly sculptured by borings, including mainly clionid sponge borings Entobia ispp., bivalve borings Gastrochaenolites torpedo and G. lapidicus, the polychaete boring Caulostrepsis taeniola and Meandropolydora isp. The borings are replaced subsequently; as a rule the succession begins with C. taeniola and terminates with Entobia ispp. The discussed boring producers display various tolerance for light, energy and depth conditions, hence their succession may reflect environmental changes, related to marine transgression, proceeded upon rocky coast area. Since such a coast could be devoid of sedimentation for a long time, the possible reconstruction of relative sea-level change may be inferred exclusively from nonsedimentological criteria i.e. from the succession of endolithic borings. Therefore the borings may be employed as useful tool in sequence stratigraphic procedure.

Opis:

The Hoanh Bo Basin has developed over multiple periods since the Miocene period in association with the tectonic activity of the Chi Linh-Hon Gai and Trung Luong Faults. The basin is filled with Neogene continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones, and shales. Coarser-grained polymictic deposits predominate along the northern and western margins of the basin, whereas different types of siltstones, claystones, and sandstones occur in its centre, as well as along its southern and eastern parts, toward the Ha Long Bay. The conglomerates and sandstones are composed mainly of quartz and sedimentary rock fragments, and a small amount of mica. Cement is mainly built of iron-oxide, clay or carbonate mud. The source area for the Hoanh Bo Basin sediments was located in the close vicinity of the basin. It was built of strongly weathered rocks of the Hon Gai, Ha Coi, Cat Ba Formations.

This publication describes the factors governing the development of containerization in Szczecin and Świnoujście Seaports Authority, together with their organizational infrastructure and economy. These factors include port access to transportation facilities, which has a major influence on economic development and strengthens the position in the Polish market. Geographic location of both the port and the status and functioning of the Szczecin-Świnoujście fairway were taken into account. The amount of container handling in the ports described in the years from 2004 to 2015 was examined. The Szczecin and Świnoujście Seaports Authority is discussed in terms of size and progress of its changes, and handling capacity compared to other marine container terminals in Poland.

Opis:

The paper presents results from a study of the functioning of slopes in conditions where the dynamic equilibrium has been upset and sliding has been followed by slope relaxation. The research was an attempt to analyze large-scale changes in slope morphology in the Łososina River basin in the Beskid Wyspowy mountain range caused by an extreme rainfall event in 1997. The enormous scale of the sliding process that occurred on the slopes of the Łososina basin provided an opportunity to study the role of mass movements in landform development in mountains of medium height. The paper attempts to summarize the rate and course of slope relaxation processes using geomorphological mapping done from 1997 to 2000. The study tested the hypothesis that following the occurrence of an extreme event, slope relaxation processes will slow down mass movement processes to the point where they stop acting on the slope, and ultimately a new set of slope development processes will emerge.
