Opis:
In their recent paper, Filipek et al. (2017) provided some data on age (dinoflagellate cyst biostratigraphy) and sedimentary setting (sedimentological and palynofacial analysis) of the Podhale Flysch (Central Carpathian Paleogene) from the Polish Spisz (their fig. 1). They carried out their integrated studies on the middle part of the Podhale Flysch succession – the upper part of the Szaflary beds through the lower part of the Chochołów beds. These studies, as stated in Introduction, “…allow for a new approach to the knowledge on the CCPB with regard to stratigraphy, depositional palaeoenvironment, and changes during deposition”.

Opis:
The article presents new research on fortified settlements from the Early Iron Age in the Orava and Dunajec river valleys. Based on the characteristics of the construction of the fortifications and similarities in terms of material culture, we propose recognizing the hillforts discovered here as a manifestation of one cultural and settlement horizon related to the so-called Pre-Púchov stage. The radiocarbon determinations obtained for the contexts stratigraphically related to the ramparts from the Nižná-Ostražica, Zabrzeż-Babia Góra, and Maszkowice-Góra Zyndrama sites are already located on the calibration curve after the so-called Hallstatt plateau and allow this horizon to be dated to the 4th century BC, i.e. to the times corresponding to the La Tène B1–B2 phases. Our observations confirm the opinions appearing in more recent literature about the need to date the Pre-Púchov stage in Slovakia earlier, and discuss the thesis about the continuation of settlement at the beginning of the La Tène period. With regard to the Polish Carpathian zone, arguments indicating the possibility of the survival of settlements with Early Iron Age traditions up to the 4th century BC are presented for the first time. This allows us to assume that the process of the formation of the cultural tradition of the La Tène period here progressed in a similar manner to Slovakia, and it was not solely the result of migration from the latter.

Opis:
Water erosion in mountainous areas is a major problem, especially on steep slopes exposed to intense precipitation. This paper presents the analysis of the topsoil loss using the SWAT (Soil and Water Assessment Tool) model. The SWAT model is a deterministic catchment model with a daily time step. It was designed to anticipate changes taking place in the catchment area, such as climate change and changes in land use and development, including the quantity and quality of water resources, soil erosion and agricultural production. In addition to hydrological and environmental aspects, the SWAT model is used to address socio-economic and demographic issues, such as water supply and food production. This program is integrated with QGIS software. The results were evaluated using the following statistical coefficients: determination (R2), Nash-Sutcliff model efficiency (NS), and percentage deviation index (PBIAS). An assessment of modelling results was made in terms of their variation according to different land cover scenarios. In the case of the scenario with no change in use, the average annual loss of topsoil (average upland sediment yield) was found to be 14.3 Mg∙ha-1. The maximum upland sediment yield was 94.6 Mg∙ha-1. On the other hand, there is an accumulation of soil material in the lower part of the catchment (in-stream sediment change), on average 13.27 Mg∙ha-1 per year.

Opis:
Systematic geological mapping of the Slovak Republic territory over the last forty years, when many regional geological maps at 1:50 000 scale were issued, culminated in 2008 and 2009 in a new synthesis of the geological structure of the Western Carpathians on the Slovak territory in the form of a general geological map at 1:200 000 scale. An integral part of this activity was the solving of interregional correlation problems, a settled of tectonic classification of the Western Carpathians as well as a specification of the lithostratigraphical content of the tectonic units. The results of this synthesis are described in this contribution - a brief review of the principal geological units of the Western Carpathians that are depicted in the tectonic interpretation and in the geological sections. The Western Carpathians are geologically divided into the Outer (Flysch Belt) and Inner (Inner Carpathian Block). These two zones are products of the youngest, mainly Neogene Neo-Alpine tectonic activity. Separating the two zones is a tectonic structure - the Klippen Belt -which contains elements from both. The Inner Carpathian Block possesses a Palaeoalpine tectonic pattern composed of crustal tectonic units and superficial nappes. The crustal units are composed of the crystalline basement and its Upper Paleozoic and Mesozoic cover. The basement consists of fragments of Hercynian tectonic units from the Paleozoic phase of crustal evolution. The superficial nappes comprise mostly upper Paleozoic and Mesozoic sequences. Cenozoic deposits and volcanic rocks are deposited on the Palaeoalpine nappe structure.

Zaobserwowano zgodność wyników pochodzących z różnych źródeł. Zestawienie danych dotyczących rożnych formacji litostratygraficznych w grupach otworów z tego samego rejonu pozwoliło na wzajemne uzupełnienie informacji. Charakterystyka gęstościowa formacji litostratygraficznych została wykorzystana do modelowania grawimetrycznego. Porowatość i gęstość zostały włączone do utworzenia zgeneralizowanych modeli własności fizycznych wybranych formacji litostratygraficznych w Karpatach Zachodnich.
The analysis of density and porosity changes was made for selected wells from the Western Carpathians. Laboratory data from the PITAKA database of the Polish Oil and Gas Company together with density logs and density values obtained from the Estymacja calculation as well as data for a few dozen samples from mercury porosimetry measurements were used. The agreement of results from different sources was observed. Data for different lithostratigraphic formations were set together for groups of wells from the same region. This enabled information to be mutually supplemented. Density characteristics of lithostratigraphic formations was used for gravity modeling. Porosity and density were employed to create generalized models of physical properties of selected lithostratigraphic formations form the Western Carpathians.

Opis:
Analysis of deposition rate were performed for synthetic sections, representing the upper Jurassic to lower Miocene sedimentary fill of the Western Outer Carpathian (WOC) basins. Calculated deposition rates differs in a range of a few orders of magnitude. During Tithonian to Berriasian-early Valanginian tectonic activity of the source areas supplying the Silesian Basin was related to the mechanism of syn-rift extensional elevation and erosion of horsts. General decay of source area activity in Valanginian to Cenomanian time was caused by regional post-rift thermal sag of the WOC. The Barremian to Albian phase of compressional uplift of the source area located north of the WOC lead to increase of deposition rate in some zones of the WOC basin. In Turonian to Paleocene time thick-skinned collision and thrusting took place south and south-west (in the recent coordinates) of the Silesian Basin causing very rapid, diachronous uplift of this zone, referred to as Silesian Ridge, resulting with high deposition rate in the Silesian Basin. At that time supply of sediments to the Magura Basin from south was relatively low, and the Pieniny Klipen Belt was presumably zone of transfer of these sediments. In Eocene the zone of collisional shortening in the WOC system was relocated to the south, causing rapid uplift of the Southern Magura Ridge and intense supply of detritus to the Magura Basin. Thrusting in the Southern Magura Ridge and collisional compression resulted with flexural bending of its broad foreland, being the reason for decrease of activity of both the Silesian Ridge and the source area at the northern rim of the WOC. The Eocene evolution of the Silesian Ridge is interpreted as controlled by both episodic tectonic activity and eustatic sea level changes. Contrasting development of the Southern Magura Ridge and the northern rim of Central Carpathians during Eocene stands for a palaeographic distance between the two domains at that time. During Oligocene and early Miocene a significant increase of deposition rates is observed for the basin in which sediments of the Krosno beds were deposited. This was caused by tectonic uplift of the source at the northern rim of the WOC, as well as the Silesian Ridge and the partly formed Magura nappe. The Miocene molasse of the WOC foredeep basin is characterised by notably higher maximum deposition rates than ones calculated for the flysch deposits of the WOC.

Opis:
The potential change of natural gas composition in the near-wel lbore zone creates a big problem with the selection of appropriate initial value of counterpressure exerted by the displacement fluid on reservoir during the test, and also with the interpretation of the reservoir and production tests results. The analysis of the industrial data reveals that the effect of condensate production in the near-wellbore zone could take place while using too high counterpres-sure during DST tests, as a consequence of using a relatively high column of water displacement fluid in the DST column, i.e. about 2500 m. This thesis can be confirmed after further detailed theoretical analysis of the occurring thermodynamic conditions. The paper addresses technological and interpretation problems encountered during drill stem tests (DST) of gas-bearing Devonian strata, on the example of the Stryszawa field in the Western Carpathians. Special attention was paid to the possible changes of gas compo sition during flow tests and the cases of gas condensation of heavier fractions during build-up tests. Attempts were made at explaining sudden drops of pressure at the build-up stage along with the thermodynamic conditions responsible for this effect. The authors explained the necessity of using an appropriate Ful-Flo sampler in the DST set for collecting gas samples at any time of the test, and devices for continuous measurement of temperature. The use of new types of drill stem testers and appropriate interpretation methods, which would account for a detailed analysis of technological and reservoir conditions allows for more efficient oil prospecting and deciding about enhancement methods in hydrocarbon production. The analysis of thermodynamic conditions on the bottom of the wellbore allow s for selecting proper counterpressure values in view of the condensation of heavier gas fractions in the near wellbore rocks. The analysis of conditions in which heavier gas fractions undergo condensation is approximate and general because the gas samples were collected at the outlet of the DST string (in surface conditions), without a Ful-Flo sampler and without temperature measurements.

Opis:
We have compared maps of landslide activity and hazard, developed with the use of two different dendrochronological indicators: tree-ring eccentricity and reaction (compression) wood. The maps were prepared based on 125 Norway spruce (Picea abies L. Karst.) trees growing at 44 sampling points, distributed over an area of 3.75 km2. In general, the two maps show similar patterns of landslide activity. However, tree-ring eccentricity yielded a greater number of dated events (246) compared to compression wood (129). Besides the differences in the absolute values of dating results, the general landslide activity and hazard zonation based on both disturbances are similar. Both growth disturbances develop as a result of stem tilting. Eccentricity develops after slight tilting, while compression wood is developed when tilting is more significant. Because of the differences in the strength of disturbing factors, which cause the development of compression wood and growth eccentricity, the best approach would be to combine the results of dating obtained from the two methods. The dendrochronological analysis of tree growth disturbances (eccentric growth and compression wood) is a promising approach for determining landslide hazards in forested mountain areas and can be applied in spatial management.

Opis:
The Upper Jurassic strata of the Krížna Unit in the Tatra Mts. comprises pelagic, fine-grained and well-oxygenated deposits. They are represented by red radiolarites and radiolarian limestones (Czajakowa Radiolarites Formation), red nodular limestones (Czorsztyn Limestones Formation) and wavy, platy or nodular light grey and reddish limestones and marlstones (Jasenina Formation). These deposits are mainly wackestones characterized by a succession of the following microfacies: radiolarian, filament-Saccocoma, Saccocoma and Globochaete–Saccocoma. The section comprises four calcareous dinoflagellate zones, i.e. the Late Kimmeridgian Moluccana Zone, and the Early Tithonian Borzai, Pulla and Malmica zones. In the uppermost part of the studied section, the Early Tithonian Dobeni Subzone of the Chitinoidella Zone has been identified. Using these biostratigraphic data, the sedimentation rate for the Late Kimmeridgian (Borzai Zone) and Early Tithonian (Dobeni Subzone of the Chitinoidella Zone) interval is estimated as 3.7 m/my. This is in accordance with the general trend of increasing sedimentation rate through the Tithonian and Berriasian. The increased supply of clastic material in the Jasenina Formation may have been caused by climate changes and continental weathering. The sedimentation was controlled mainly by eustatic changes and fluctuations in ACD and CCD levels.

Opis:
In the Klape Unit of the Pieniny Klippen Belt the Albian conglomerates with clasts of exotic carbonates, clastic sediments and also volcanic and plutonic rocks are relatively widespread. In the small area near the town Povażska Bystrica also scarce blueschist clasts of variegated petrographic types have been found. Three groups of starting rocks can be discerned for blueschists: pelagic sediments, metamorphic rocks (amphibolites, gneisses) and volcanic rocks. Based on immobile trace element (HFSE, REE) distribution two petrogenetic types of volcanic rocks have been identified: basalts with BABB signature and calc-alkaline basaltic andesites to rhyolites. Source of these rocks was probably a nappe stack located in the Carpathian interior and created in the Late Jurassic time as a result of subduction of the oceanic crust and adjacent volcanic arc and followed by collision during the Meliata Ocean closure
Albskie zlepieńce jednostki klapskiej pienińskiego pasa skałkowego zawierające egzotyki skał węglanowych, klastycznych, jak również wulkanicznych i plutonicznych są szeroko rozprzestrzenione. Na małym obszarze w okolicy Povażskiej Bystricy (Słowacja zachodnia) w kilku stanowiskach znaleziono rzadkie egzotyki zróżnicowanych petrograficznie łupków glaukofanowych. Wyróżniono trzy grupy pierwotnych utworów przekształconych w te łupki: osady pelagiczne, skały metamorficzne (amfibolity, gnejsy) i skały wulkaniczne. W oparciu o niestabilne pierwiastki śladowe (HFSE, REE) zidentyfikowano dwa typy petrogenetyczne skał wulkanicznych: bazalty o cechach bazaltów obszarów zaułkowych (BABB) oraz wapniowo-alkaliczne andezyty i ryolity bazaltowe. Obszarem źródłowym tych skał były prawdopodobnie spłaszczowinowane jednostki zlokalizowane w obrębie Karpat wewnętrznych, powstałe w późnej jurze jako rezultat subdukcji skorupy oceanicznej i utworzonego w związku z tym łuku wulkanicznego, w następstwie kolizji podczas zamykania się oceanu Meliaty
