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.

Opis:

Detailed lithostratigraphic data from a borehole in the Abrămuţ Basin, located in the northwestern part of Romania, has revealed the presence of turbiditic deposits containing several layers with tuff/tuffaceous materials in the lower Badenian. The age of these deposits is determined by the presence of the foraminifera Praeorbulina glomerosa and Orbulina suturalis. Detailed quantitative and qualitative X-ray diffraction data (XRD) on 10 different tuff layers situated at depths between 2450 and 2640 m show a mineralogical association comprising analcime, quartz, volcanic glass, smectite, mica, calcite, K-feldspar, glass and minor quantity of chlorite and albite. The presence of analcime suggests that the albite isograd for the interval studied has been never reached and the maximum temperatures have been lower than c. 125degrees C since the early Badenian.

Opis:

Elemental and mineral composition of Gold Basin and El Hammami meteorites discovered in 1995 and 1997 have been studied by analytical electron microscopy and optical microscopy. It was established that the main meteorite minerals: olivines, pyroxenes, kamacite and taenite as well as troilite identified in the samples represent extraterrestrial minerals typical of the ordinary chondrites. Feldspars represented by plagioclase, orthoclase, magnetite, calcite, chromite and silica have been also present in the studied samples. Chemical and mineral composition, iron content, petrologic types of chondrules, their abundance and sizes, the presence of troilite veins and abundance of nonoxidised iron phases confirm H class of El Hammami chondrite, i.e.. olvine-bronzite class, and L class of Gold Basin, i.e. olivine-hyperstene class.
Badano skład chemiczny i mineralny meteorytów Gold Basin i El Hammami. Zanalizowano chondry i ciasto skalne. Obecność chondr oliwinowych, chondr piroksenowych, żył troilitowych oraz faz żelazo-niklowych: kamacytu i troilitu świadczą o pozaziemskim pochodzeniu badanych skał. Oprócz minerałów najbardziej rozpowszechnionych w meteorytach takich jak: oliwin, piroksen, kamacyt, taenit i troilit wykryto także plagiklazy, magnetyt, kalcyt, chromit, ortoklaz i krzemionkę. Zgodnie z uprzednią klasyfikacją Gold Basin jest chondrytem klasy L o niskiej zawartości żelaza, a El Hammami chondrytem typu H zawierającym dużo żelaza.

Opis:

Water-table levels in the Kamienna River drainage basin, SE Poland, are presently measured at 14 observation points within the groundwater observation-research network of the Polish Geological Institute – National Research Institute, included in the monitoring programme during the period 1979–2007. They exhibit multi-year changes in groundwater storage near the observation points. The best documented cycle is that for the period 1982–2002, observed in the wells monitoring water in fractured-karstic formations, where the amplitude of the water-table level was 45 m at that time. The retention balance in the cycle was negative. At the beginning of the cycle, the water table in the fractured-karstic aquifers was 1.40 to 1.94 m higher than at the end. Further observations of the multi-year changes in retention will be the basis for possible corrections to calculations of groundwater resources in this drainage basin, as well as for model predictions of resources, performed for water management in connection with potential climate change.

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.

Opis:

The Late Cretaceous to Oligocene strata of the Dukla Nappe, which is a part of the accretionary wedge formed in front of the Carpathian orogen, record a history of the basin development from remnant to foreland basin stages. The lower part of the succession indicates the first stage of basin evolution characterized by turbidite systems fed from the E (NE) to W (SW). The system encompasses deposits of the Łupków and Cisna formations deposited in a channel-lobe transition (Łupków Fm.) and in sandstone-rich channelized lobes (Cisna Fm.) The transitional phase is represented by deposits of the Submenilite Formation derived from two different sources (SE and N) and deposited in a submarine slope/ramp environment. The third stage of basin evolution is marked by the advancing front of the Carpathian orogen resulting in peripheral foreland basin development. Increased tectonic activity led to a switch in sediment source from the SE to the NW, more complex topography of the basin and a change in sediment distribution. The initial phase of this stage is characterized by low-density turbidites and suspension fall-out sediments of the Menilite Fm. Discrete tectonic pulses are recorded by the thick Cergowa sandstones, mostly deposited by hybrid flows and high-density turbidity currents. A decrease in tectonic activity is suggested by heterolithic deposits of the Krosno Fm. capping the sedimentary succession.

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.

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:

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.

The article presents a short description of the municipalities, located in the immediate vicinity of the Biebrza River. They are: Lipsk, Sztabin and Nowy Dwor. The Biebrza Valley is an area of great natural significance, mainly due to its largest wetlands in Central and Western Europe. Their well-being depends mainly on the hydrologic conditions. Biebrza National Park and the area of the Upper Biebrza Basin, have been reported by Poland to the the Ramsar Convention, NATURA 2000, BirdLife International classification. Therefore, water, as a basic element of shaping the whole Biebrza Valley habitat is also protection subject, including constant monitoring of water quality. The aim of the article was to characterize the Upper Biebrza Basin which covers the area between the Sztabin Village and the Polish border with Belarus.

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 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.

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.

Opis:

In the area of the Polish Basin five deep seismic sounding profiles, recorded during 1991–1997, were used to compare the structure of the crystalline and consolidated crusts with that of the sedimentary cover. Repeated reactivation of deep crustal fractures controlled the thickness distribution and development of faults in Palaeozoic andMesozoic sequences.NW–SE toWNW–ESE basin-parallel and transverse N–S to NE–SW striking fracture systems are evident. The former includes the isseyre–Tornquist Zone that marks the profound crustal boundary between the East European Craton and the typical Trans-European Suture Zone (TESZ) crust that is characterized by a variably thick consolidated upper crustal layer, composed of Caledonian-deformed Early Palaeozoic and possibly Vendian sediments, and defines the NE boundary of the Permian and Mesozoic Mid-Polish Trough (MPT). Its northwestern TTZ segment was intermittently active throughout the whole geological history of the area. The SWboundary of the TESZ, marked by the Dolsk Fault across which the consolidated crustal layer is replaced by a crystalline Variscan upper crust, is only evident on profiles LT-7 and P4. The deformation front of the Variscan Externides is located some 100 km to the NE of the Dolsk Fault within the confines of the TESZ crust. On profiles TTZ-PL and P2, significant lateral changes in the thickness of the consolidated and crystalline crust of the Pomeranian, Kuiavian and Holy Cross Mts. segments of the MPT are noted that coincide with the transverse Bydgoszcz-Poznań-Toruń and Grójec fault zones. These crustal changes are associated with substantial changes in the composition and thickness of supracrustal sedimentary sequences and the degree of inversion of the MPT.

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:

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.

Numerous remains of amphibians and squamates were discovered in the continental sediments of the Maastrichtian Sânpetru Formation, south of Pui Village (Haţeg Basin, western Romania). The lissamphibians are represented by a salamander−like allocaudatan (Albanerpeton sp.) and at least two discoglossid frogs (cf. Eodiscoglossussp. and cf. Paradiscoglossussp.). The numerous lizards are represented by, e.g., the teiid Bicuspidon hatzegiensissp. nov., and for the first time in a Late Cretaceous site, by two species of the paramacellodid Becklesius (Becklesius nopcsai sp. nov. and Becklesius cf. B. hoffstetteri). Snakes are also present in this site by an indeterminante madtsoiid, which represents the first occurrence of this family in eastern Europe. The presence of Albanerpeton in this site confirms that this genus appeared in Europe by at least the Late Cretaceous instead of Miocene as previously thought. The presence of both Albanerpeton and Bicuspidon in Haţeg Basin suggests a North American influence on eastern European amphibian and lacertilian faunas by Maastrichtian times.

Opis:

The Cunge-Muskingum routing model is one of the most popular and widely used models for hydrologic channel flood routing. The application of Cunge-Muskingum model to an ungauged basin is hindered by the lack of hydro-meteorological data. In the present study, a method is proposed to predict the outflow hydrograph of an ungauged basin as a solution to this problem. The Cunge-Muskingum method is modified, considering the non-prismatic complex natural channel. The Soil Conservation Service Curve Number rainfall-runoff model is employed to obtain the inflow and lateral inflow hydrographs of the ungauged basins, and the Modified Cunge-Muskingum model is employed to anticipate the flood hydrograph at the outlet of the ungauged basin. The proposed approach is employed to the Kulsi River Basin, India, hypothetically treated as an ungauged basin, and the results are compared with the observed data at the outlet of the basin. The performance of the model is evaluated based on RMSE (50.34 m3/s), peak flow error (39.73%), peak flow time error (-3.44%), total volume error (7.36%), relative error (7.36%), mean absolute error (33.5%), correlation coefficient (0.785), coefficient of efficiency (0.59) and Kling-Gupta efficiency (0.66).The results reveal that the proposed Modified Cunge-Muskingum model is an efficient predictor of the flood hydrograph at the outlet of the ungauged basin.

Opis:

System naftowy z gazem w centrum basenu (BCGS) ma charakter niekonwencjonalnych, regionalnych akumulacji gazu ziemnego. W systemie takim strefa głęboko zalegających zwięzłych skał zbiornikowych, nasyconych gazem, w górę powierzchni strukturalnych przechodzi stopniowo w strefę o konwencjonalnym wykształceniu, nasyconą wodami złożowymi. BCGS wymaga, by skała zbiornikowa nadścielała, lub przeławicała się z dojrzałymi skałami macierzystymi, zaś mechanizmem uszczelnienia jest niska przepuszczalność formacji zbiornikowej. Nie wymaga on obecności pułapek złożowych. Model ten jest tu użyty w odniesieniu do karbońskiego basenu górnośląskiego (BGŚ), który pozostaje globalnie unikalnym przykładem basenu nieomal niezbadanego pod kątem możliwości występowania złóż węglowodorów. Model ten nie może być obecnie bezpośrednio zweryfikowany z uwagi na brak odpowiednio głębokich otworów wiertniczych w kluczowej, centralnej części BGŚ (rejon Rybnik–Żory–Tychy–Mikołów). Zakłada on zwięzłe wykształcenie skał potencjalnie zbiornikowych na głębokościach 3500÷5000 m. Rolę skał zbiornikowych pełnić w tym przypadku mogą pakiety piaskowców serii paralicznej, a w mniejszym stopniu również górnośląskiej serii piaskowcowej, cechujące się dużą miąższością i znaczną regionalną rozciągłością. Utwory tych serii w centralnej części BGŚ zawierają ponadto pokłady węgla kamiennego oraz pakiety łupków węglowych, stanowiące efektywną skałę macierzystą dla gazu ziemnego. Główny czynnik ryzyka poszukiwawczego stanowi czas generowania węglowodorów: im starszy tym większe prawdopodobieństwo rozformowania akumulacji gazu ziemnego. W przypadku waryscyjskiego wieku generowania gazu ziemnego w BGŚ prawdopodobieństwo rozformowania jego akumulacji typu BCGS należy uznać za wysokie. Ponadto elementami ryzyka poszukiwawczego są możliwość przegrzania skał macierzystych, a także duży zakres niepewności co do wykształcenia własności petrofizycznych skał zbiornikowych. Możliwe, prognostyczne zasoby wydobywalne tego typu akumulacji w BGŚ wstępnie określono na około 100÷250 mld m3. Weryfikacja omawianego modelu oraz związanych z nim zasobów gazu zamkniętego warunkowana jest odwierceniem głębokich otworów poszukiwawczych.
Basin Centered Gas System (BCGS) is characteristic of numerous unconventional, pervasive tight gas accumulations, where deep gas-saturated tight reservoir passes up-section into its water-saturated conventional zone. In such a system tight reservoir overlies or interbeds with mature source rocks, while the sealing mechanism is the low permeability of the reservoir formation. The system does not require the presence of hydrocarbon traps. This model is applied here to the Carboniferous Upper Silesian Basin (USB), which is one of the few onshore sedimentary basins in the World which has not been explored for oil and gas. The concept cannot be currently verified due to the lack of deep boreholes in the central part of the USB (region: Rybnik–Żory–Tychy–Mikołów). It requires tight reservoir properties at depths of 3500÷5000 m. The reservoir formations are the sandstone of the Paralic Series, and to a lesser degree also of the Upper Silesian Sandstone Series, characterized by immense thickness and considerable lateral reach. Both Series at that depth interval contain also coal seams and coal shale, being effective gas source rock. The key exploration risk is the timing of gas generation: the older the generation, the higher the risk of gas release. In the case of the Variscan generation, recent preservation gas in the form of BCGS accumulations is unlikely. Other risk factors are possible source rocks overmaturation and uncertainty as for the reservoir’s petrophysical properties. Possible prospective resources of the BCGS accumulations in the USB were preliminarily estimated for approx. 100÷250 Bcm. Validation of the model of the BCGS being developed in the USB, as well as verification of the resources related to it, requires drilling new deep exploration wells.

In this study, fit-testing of primary inclusions was performed to reconstruct the physical and chemical conditions during original halite sedimentation. During the post-sedimentation stage, salt was subjected to elevated temperatures (62-70°C) and pressures of tens of megapascals. From these measurements and mathematical calculations, the gas pressure was identified in the primary fluid inclusions, which allowed us to estimate that the brine column thickness in the salt basin was approximately 40 m.

The ciliate Mesodinium rubrum Lohmann 1908 (= Myrionecta rubra Jankowski 1976) is an important phototrophic organismin the Gdańsk Basin. In June 2002 the vertical distribution and size structure of the M. rubrum population were studied. Its presence was generally observed in the whole water column (one exception was the anoxic near-bottom zone in the Gdańsk Deep) at all stations studied. Maximum abundance (18 300 cells dm−3) was recorded at 26 m depth at the station located in the inner Gulf of Gdańsk. Analysis of the size structure of the counted organisms demonstrated the co-existence of small and large cells of M. rubrum in the upper layer of the water column and a gradual increase with depth of the prevalence of large specimens. This shows that at least two forms of M. rubrum exist in the region studied. Deep migrations are probably undertaken only by relatively large organisms.

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.

Five taxa of chondrichthyan teeth — Acrodus lateralis, Acrodus cf. lateralis, Acrodus sp., Palaeobates angustissimus, Palaeobates sp. and, for the first time from this region, two taxa of osteichthyan remains — teeth of Birgeria sp., scales from Gyrolepis sp. as well as scales from unclassified actinopterygians and enigmatic bones (fishes?) are described from the Lower Muschelkalk at Raciborowice Górne. Reptile teeth represent ing the Nothosauridae or Cymatosauridae have been found for the first time at this locality. They were discovered in the Bone Bed of unit C, that had previously only yielded fish teeth. The material collected has allowed reconstruction of the vertebrate as semblage of the Lower Muschelkalk of the North-Sudetic Basin. It has also helped to constrain reconstructions of the palaeoenvironment, sugesting that it represented a deepening lagoon. The assemblage has been correlated with age-equivalents from other regions of Europe, the faunas from the Holy Cross Mts. (Central Poland) being the closest analogy. The evidence indicates that, during the deposition of units Band C that, contain the vertebrate remains, connection with the Tethys Ocean was through the Silesian–Moravian and East Carpathian marine gateways.

Opis:

The aim of this study is to construct a seismo-geological model of the western part of the Baltic Syneclise. This model enables reconstruction of the tectonic processes taking place in this area, which had a significant impact on the formation of prospective zones for the occurrence of unconventional hydrocarbon accumulations. The two seismic surveys Opalino 3D and Kościerzyna-Gdańsk 2D, together with borehole data available in the vicinity, were used for the research. Well data were used not only for the seismic-to-well tie, but also for the construction of well cross-sections (including balanced ones). The structural interpretation of seismic boundaries enabled the separation of four structural stages: Precambrian; Caledonian, Permian-Mesozoic and Cenozoic. The seismic interpretation of the Opalino 3D survey indicates the presence of block-style tectonics in this area. This system is considered to be a part of a large block system, also extending throughout the area of the 2D survey. The Caledonian interval shows the greatest degree of structural complexity. Most of the large Palaeozoic dislocations already had been formed in the Cambrian. They underwent reactivation and/or inversion in the Silurian, or in the final stages of the Caledonian and/or Variscan Orogeny, at the latest. The current shape and structure of the Baltic Syneclise and the development of the Palaeozoic sedimentary cover were significantly influenced by the processes taking place in the Teisseyre-Tornquist Zone (TTZ). The dislocations of the Lower Palaeozoic stage are characterized by general NW-SE and NE-SW trends, although the first of these seems to be dominant.

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.

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:

Nanoflagellates are important bacterivores, but their role is often underestimated because forms capable of phagotrophy and containing chlorophyll (mixotrophs) are excluded from analyses. Research conducted in the coastal zone of the Gdańsk Basin (Baltic Sea) revealed seasonal changes in the relationship between the biomasses of small (1–8 μm) nanoflagellates with (NFChl+) and without chlorophyll (NFChl–). Three distinct patterns were distinguished: (i) spring, when the biomass of NFChl+ was lower than that of NFChl–, (ii) summer and autumn, when NFChl+ were dominant (about 90%), and (iii) late autumn and winter, when the prevalence of NFChl+ was lower (71–79%). Additional studies showed the existence of spatial differences in the composition of the nanoflagellate community. These spatial differences were not shaped by freshwater input. The possible importance of mixotrophic forms in the Gdańsk Basin is discussed.

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 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.

Opis:

A refined, stratigraphic and biostratigraphic framework for Ethiopia has a strong bearing on the Jurassic sedimentary evolution, not only for the Horn of Africa, but also for the North African region. The present contribution provides an updated Callovian-Kimmeridgian stratigraphy and biostratigraphy, on the basis of the occurrences of age-diagnostic ammonites from Dejen (Blue Nile Basin; central western Ethiopia). Here, the late Callovian (Lamberti Zone) ammonite Pachyceras cf. lalandeanum (d'Orbigny) is associated with the nautiloid Paracenoceras cf. giganteum (d'Orbigny). The early Kimmeridgian Orthosphinctes aff. tiziani (Oppel) is associated with the nautiloids Paracenoceras cf. kumagunense (Waagen) and P. cf. ennianus (Dacqué) and a large gastropod Purpuroidea gigas (Étallon). The previously recorded middle Callovian ammonite Erymnoceras cf. coronatum (Bruguiere) is associated with the now recorded P. gigas (Étallon). Additionally, the age of the Antalo Limestone Fm is also reassessed on the basis of the ammonite records from the three basins - Ogaden, Blue Nile and Mekele. The Ogaden Basin strata span from the late Callovian to the late Tithonian (from ammonite records), the Blue Nile Basin from the early Callovian to the late Tithonian (calcareous nannofossils) and the Mekele Basin from the uppermost middle Oxfordian to the early Kimmeridgian (ammonite records). However, the upper age assignments should be considered tentative, as much of the previously recorded Oxfordian-Kimmeridgian ammonite fauna needs taxonomic re-evaluation and precise resampling. Contextually, it should be mentioned that in all the three sedimentary basins, the top part of the Antalo Limestone Fm did not yield any ammonites.

Opis:

At present, hydro-geothermal resources in which waters in bores are the carrier of heat energy have commercial importance in Poland. Geothermal waters should feature the highest possible temperature in the outflow, low mineral content, high capacity and low deposit depth. Even though geothermal energy is included in renewable sources of energy, complete depletion of the deposit is the largest risk in extracting geothermal waters. This is why these waters should also feature deposit renewability. There are currently several geothermal provinces with beneficial geothermal conditions in Poland, with the area of the Podhale Basin in the Inner Carpathians region being regarded as the most promising. The Podhale deposit also meets all of the above listed conditions. The possibility of using hydrothermal energy in Poland is practically available throughout the country, but operational use of hot groundwater must be profitable for investors. From another point of view, the environmental impact of such investments should be minimized. This paper is concerned with the special variety of temperature of geothermal waters extracted in the area of the Podhale Basin, which is the basic aspect in using deposits of this type.

Opis:

Eight ichnotaxa and enigmatic tubular forms were discovered and described for the first time from clastic deposits (the Culm facies) of the uppermost part of the Szczawno Formation (upper Mississippian) from in the Piaskowa Góra section in the northern part of the Intra-Sudetic Basin near Wałbrzych. The trace fossils are represented mostly by pascichnia and less numerous domichnia, fodinichnia and repichnia. Psammichnites plummeri and numerous Phycosiphon isp. are the most common ichnotaxa. They are accompanied by Archaeonassa fossulata, Beaconites cf. capronus, Curvolithus multiplex, Dictyodora liebeana, Palaeophycus isp., and Planolites isp. D. liebeana is described for the first time from the lower Serpukhovian. Most components of the ichnoassem-blage are typical of the Cruziana ichnofacies, but the co-occurrence of Dictyodora and Phycosiphon could indicate a transition to deeper environmental settings (the Zoophycos ichnofacies). The lithological features as well as the accompanying trace fossils, wrinkle structures and floral remains of Archaeocalamites indicate rapid sedimentation, alternating with more tranquil periods of sedimentation, in an intermediate environment between the lower offshore (the distal Cruziana ichnofacies) and the fan-delta slope (below the wave base, the Zoophycos ichnofacies). The studied trace fossils and palynological data indicate that marine conditions in the Wałbrzych area in the Mississippian prevailed locally until the early Sepukhovian.

W obszarze LZW konfiguracja współczesnego pola cieplnego nie wykazuje związku z polem jakości węgla. W obszarze GZW współczesne pole cieplne jak również pole maksymalnych temperatur, których wskaźnikiem jest stopień dojrzałości termicznej organicznej materii, wyraźnie korelują ze sobą wykazując podobne generalne trendy wzrostu aktywności termicznej w kierunkach z SE na NW i SW. Hipotetycznie zakładamy, że podwyższone temperatury były efektem dodatkowego podgrzania po inwersji tektonicznej basenu w fazie asturyjskiej.
The papers contains analysis and correlation of parameters of thermal field with special stress on density of the heat flow in hard coal basins i.e.: Upper Silesian Coal Basin (USCB) and Lublin Coal Basin (LCB). The density of the heat flow in the USCB varies from 50 to over 90 mW/m2 (mean value - 70.4-8.5 mW/m2), but in the area of the LCB it varies from 40 to over 70 mW/m2 (mean value - 62-10 mW/m2). The modern thermal field in the LCB don't correlate to the hard coal quality field. The positive anomalies of the thermal field observed in SW part of the USCB, are convergent to the positive anomalies of hard coal maturity degree of organic matter. Hypothetically assumed theory is given there was an extra heating of massive after tectonical inversion of the USCB in astarian phase.

Opis:

The paper presents the changes of coal seams quality near fault zones. Three types of relations have been found. The first one shows an increase of coal quality at the 0.2 m distance from fault surface, as a result of increase of coalification degree. It is assumed that, this type was caused by heat of friction which was rising during faulting. It is revealed as an increase of such parameters as: caking properties, vitrinite reflectance, calorific value and carbon content, as well as the decrease of oxygen, ash, and moisture content. The second type presents differed degree of coal quality decrease. This type was produced due to hypergenic processes. The author found four subtypes of oxidation-type changes of coal quality parameters in fault zones. The first one shows the highest level of hypergenic processes in a coal seam about 1 m off a fault plane. The second presents minor degree of oxidation processes in the coal seam at a smaller distance from the fault. The third one demonstrates minimum oxidation changes of coal quality at a distance of 0.2 m from the fault. The fourth subtype of the oxidation changes of coal quality has been observed only in tectonic breccia and not in the coal seams itself.The third types demonstrates faults which do not show any impact on changes of coal quality parameters. To this type belong faults from SW part of USCB and faults with downthrown up to 20 m.

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:

One of the major projects in regional hydrogeological investigations in Poland is a multi-annual cycle of studies on the implementation of programs and documentation in relation to the establishment of protection areas for the Major Groundwater Basins (MGBs). Depending on the size of the area and complexity of the selected aquifer system, the work on the numerical model becomes adequately demanding. The model must in this case be designed as a three-dimensional, multi-layered, taking into account the role of a near the surface aquifer in the potential rate of migration of contaminants. It is particularly difficult to design models of the basins located in the older Mesozoic hydrogeological structures of dual-porosity characteristic, covered by Neogenic and Quaternary sediments. One of these basins is MGB No. 317 (ed. Kleczkowski 1990) identified within the northern Sudetic trough. The boundaries of the MGB are associated with the occurrence of structural aquifer limits, including the relatively large area of outcrops of the upper Cretaceous sediments with a narrow zone of Triassic outcrops. The paper presents the main assumptions of the model schematization, especially regarding the parameterization of hydrostructural conditions in integration with geoinformatic tools and MODFLOW modules. This study is focused on the problems associated with the proper schematization of the multilayer groundwater system on a regional scale, particularly with regard to the first aquifer and its hydraulic contact with the Mesozoic water-bearing horizons of the MGB. Model simulations, together with a semi-analytical analysis of the rate of flow in the vadose zone, finally allowed to determine the protection area of the MGB that is presented.

Opis:

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

Opis:

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.

Opis:

Changes in land use / land cover, coupled with poor management systems, can result in a high rate of soil erosion and increased sediment transport by changing the extent and structure of runoff and sediment yield. The purpose of this study was to assess sediment yield and conservation practices in the Akaki watershed using the Soil and Water Assessment Tool (SWAT) model. The watershed has been severely degraded due to increasing urbanization, deforestation, careless use of land and water resources that have led to soil erosion. MUSLES were used to estimate sediment yield in watersheds. SWAT has been used to delineate the watershed and to analyze the slope of the watershed, soils and land uses. In addition, ground control points, interviews and field observations were conducted to collect data on the effects of soil erosion and the status of existing conservation measures. The average annual soil loss in the study area is estimated at 2.12 tonnes / ha / year due to the high erosivity of rainfall in the region. In addition, the results showed a direct relationship between precipitation and sediment yield. Spatial variability of sediment yield was performed using simulated sediment yield results for LULC generated. Also based on the spatial outcome for critical sub-watersheds, the design and development of best management practices were proposed under different scenarios. The scenarios showed that the average annual reduction in sediment yield at the sub-basins of hot spots after the application of filter belts, terraces and stone bunds was 75.6%, 68.8% and 69.6% respectively, 4% of sediment reduction. Therefore, the placement of filter strips for the Akaki catchment should be developed and encouraged for effective sediment reduction.

Opis:

The uppermost Westphalian marine horizon (Dunbarella horizon) is especially important for correlation of Carboniferous deposits in the Lublin Coal Basin and in other basins of the Northwest European Carboniferous Basin. The Dunbarella horizon is characterized by cyclic sedimentation and consequent faunal spectrum variability, typical for Westphalian marine horizons of northwestern Europe. Palaeontological study of the Dunbarella horizon showed the presence of macrofauna representing different palaeoenvironments, from marine to brackish (non-marine) and freshwater conditions. The vertical sea level fluctuations and changes in seawater salinity resulting in palaeontological record changes do not link with geochemical proxies. TOC, redox-sensitive trace element concentrations, and V/Cr, Ni/Co and V/(V + Ni) ratios generally suggest that the Dunbarella horizon sediments were deposited under predominantly oxic conditions (with local exceptions during the initial phase of the Dunbarella ingression; Kopina 1 borehole).

Opis:

Rich assemblages of the Namurian miospores were recorded in the deposits of the Wałbrzych Formation from the northern part of the Intrasudetic 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).

Opis:

The Middle Permian Tapinocephalus Assemblage Zone in South Africa has produced a rich record of tetrapods dominated by dinocephalian therapsids and pareiasaurid parareptiles. In this study we reassess the affinities of a specimen from this horizon previously identified as a procolophonoid and provide evidence that it is instead referable to a nycteroleter parareptile, an identification that is more compatible with the age of this fossil. Accordingly, this specimen represents the first record of a nycteroleter in Gondwana.
