Opis:
In the Ukrainian part of the Silesian Nappe (Outer Carpathians, Uzh River Basin) the exotic clast-bearing Uzhok Olistostrome (up to 60 m thick) occurs within the Oligocene Krosno Formation and underlies the Pikui Sandstone (Otryt Sandstone in Poland). The Uzhok Olistostrome consists of debris/grain/mud flow deposits with clasts of schist and bioclastic limestone. These deposits contain redeposited pelagic sediments with planktonic foraminifers including Parogloborotalia pseudocontinuosa (Jenkins), Ciperoella ciperoensis (Bolli), Globoturborotalita woodi (Jenkins), Chiloguembelina adriatica Premec Fucek, Hernitz Kucenjak and Huber. The age of the Uzhok Olistostrome based on planktonic foraminifers correlates with the middle Oligocene within the middle O2–O5 zones. The source area for the Uzhok Olistostrome and Pikui Sandstone was a mid-Oligocene intrabasinal palaeouplift (the Pikui Ridge) interpreted as the fore-bulge located in the Silesian Sub-basin ahead the emerging Outer Carpathian accretionary prism (including the Dukla Nappe and other West Carpathian inner flysch nappes).

Opis:
Basing on 2054 georeferenced occurrences of ten Aconitum species, the initial map of the species richness per each of 57 operational geographic units (OGU) of the Ukrainian Carpathian Region (UCR) has been developed. Next, to avoid unequal data distribution, we counted absolute species presence per OGU, based on which we calculated ‘rarity-weighted richness’ (RWR) and performed parsimony analysis. As a result, we found that Chornohora and Svydovets made a strongly supported cluster with the highest Aconitum species diversity and demonstrated the highest RWR values, hence being the main hot-spot of the genus distribution in the UCR. This main hot-spot also spreads to adjacent mountain ranges, including Maramures and Gorgany. Probably, a continuous gradient of Aconitum taxonomic richness from southeast toward northwest of the UCR existed before. The gap in Polonyna Borzhava, located between Polonyna Rivna and Polonyna Rivna, can be secondarily resulted by the high level of anthropogenic transformation of this region. Contrary, the high RWR value and distinct clustering of the Polonyna Rivna supported the presence of a local isolated Aconitum hot-spot related to two prominent mountain peaks located here - Runa-Plai Mt. (in Polonyna Rivna) and Pikui Mt. (in adjacen Waterdivided Mountain Range).
Na podstawie analizy 2054 georeferencyjnych wystąpień dziesięciu gatunków rodzaju Aconitum opracowano wstępną mapę bogactwa gatunkowego w każdym z 57 operacyjnych jednostek geograficznych (OGU) Ukraińskiego Karpackiego Regionu (UKR). Następnie, aby uniknąć nierównego rozkładu danych, policzyliśmy bezwzględną obecność gatunków w każdym OGU, obliczyliśmy bogactwo ważone rzadkością (RWR) i wykonaliśmy analizę parsymonii. W rezultacie stwierdziliśmy, że Czarnohora i Svydovets utworzyły silnie poparte ugrupowanie o najwyższym bogactwie gatunków Aconitum i wykazywały najwyższe wartości RWR, będąc tym samym głównym hotspot rozmieszczenia rodzaju w UCR. Ten główny hots-pot rozciąga się również na sąsiednie pasma górskie, w tym Maramures i Gorgany. Prawdopodobnie w UKR istnieje gradient bogactwa taksonomicznego Aconitum z południowego wschodu na północny zachód. Luka w Borżawie, położonej między Równą a Krasą, może być wtórnie spowodowana wysokim stopniem antropogenicznej transformacji tego regionu. Natomiast wysoka wartość RWR i wyraźna odrębność Połoniny Rivna wskazuje na obecność lokalnego, izolowanego hotspot rodzaju Aconitum, związanego z dwoma jej głównymi szczytami górskimi - Runa-Plai (na Połoniny Rivna) i Pikui (na Werchowynśkim Wododilnim Chrebetie).

Opis:
The consideration was given to the geological and geomorphological factors of natural hazards in the Ukrainian Carpathians. Principal impact of rock lithology, geomorphological structure, underwater regime and seismic processes on the erosion, gravitational and water-gravitational processes formation was demonstrated. The research confirmed a special role of the tectonic factor and the presence of weak zones in the development of natural hazards. Weak zones are characterized by fracturing, brecciation, bedding of flysch deposits and contrast in permeability. The strength properties of rocks decrease drastically within such zones, and large-scale landslide formation processes occur, especially in the case of subparallel location of zones, relative to river valleys and slopes. The factors of hazardous geological processes were defined and classified using GIS analysis and the developed geological model. A conceptual model of landslide hazards in the area of Carpathian Mountains was developed. Weight coefficients of potentially landslide prone factors were determined from the on-site observations and archive data. An integral spatial map of landslide susceptibility was proposed. The results of this research were the basis of geological environment modeling for the assessment of hazardous geological processes impact on the functioning of infrastructure objects.

Opis:
Existing knowledge of the Ukrainian foresters related to the historical changes and current state of silver fir forests, as well as on the various methods of restoration of such forests in the Ukrainian Carpathians were discussed. Forest cover of fir stands in this region has been diminishing in the last two centuries. Only in the period from 1947 to 1956, the area of fir stands in Ukrainian Carpathians decreased by 38.8%. Currently, the restoration of fir stands in these areas are crucial for Ukrainian forestry. Therefore, the natural as well as artificial regeneration using seeds obtained from seed orchards are currently used. Thus, improving the forest stands’ conditions mostly composed of singlespruce plantations need to be improved through changing the species compositions. However, the restoration of fir stands is time and labour-intensive, and require a long-term strategy.

The Parvularugoglobigerina eugubina Zone (Lower Danian), Acarinina acarinata Zone (Upper Thanetian), Morozovella subbotinae Zone and Morozovella aragonensis Zone (Ypresian), Acarinina bullbrooki Zone and Acarinina rotundimarginata Zone (Lutetian), Subbotina corpulenta Zone and Subbotina vialovi Zone (Upper Priabonian – Lower Rupelian) based on planktonic foraminifera as well as the Rzehakina fissistomata sensu lato Zone (Paleocene), Glomospira charoides–Recurvoides smugarensis Zone (Ypresian), and an assemblage with Haplophragmoides parvulus (latest Mid Eocene-early Late Eocene) based on agglutinated foraminifera have been identified in these deposits. The deep-water agglutinated foraminifera of the “Rzehakina”, “Rhabdammina” and “Paratrochamminoides” assemblages found in the typical flysch deposits of the Sushmanets Formation indicate lower slope to abyssal environments below the CCD. The generic composition and morphological features of planktonic and benthic foraminifera recovered from marls of the Metova Formation suggest pelagic/hemipelagic conditions at bathyal depths above the foraminiferal lysocline.

Opis:
Background. Ukrainian Carpathians cover 4% of the Ukraine area and 10.3% of the total area of the Carpathians. The region is among those most often visited by tourists in Ukraine. The values of this part of the Carpathians constitute a natural impulse to the development of tourism in the country. The paper presents the possibilities to practice active tourism in the Ukrainian Carpathians. The main aim is to discover the tourist and recreational infrastructure of the Carpathians, as well as identifying opportunities and problems bound with practicing various forms of active tourism in the Ukrainian Carpathians. Material and methods. The material was collected through field research combined with direct observation and diagnostic polls in a group of experts from the tourist industry in Ukraine. Analysis of source materials, maps, and guides was also performed. Conclusion. The tourist and recreational potential of the Ukrainian Carpathians is very high, allowing for significant opportunities for active tourism development. There are, however, substantial obstacles, bound with lack of sufficient infrastructure and consistent support by the authorities. The authors indicated tasks to be solved in order to improve the condition of tourist industry.

Opis:
Lopushna oil field has been discovered in Mesozoic-Paleogene strata of the platform basement under the Ukrainian Outer (Flysch) Carpathians. Oils from two main accumulations, occurring in the Upper Cretaceous sandstone and Upper Jurassic limestone reservoirs, have been analysed in order to identify their origin and relation to the known petroleum systems in the region of the Outer Carpathians and the basement of the Carpathian Foredeep. Results of geochemical investigations of oils, including biomarker and isotopic data, show a good correlation with oils, accumulated in the Carpathian flysch strata. Oils are low-sulphur and did not undergo significant degradation. They were generated from Type II or II/III kerogen, deposited in anoxic environments in clastic sediments. Generation occurred at the peak of “oil window”, probably in the temperature range of 122 to 126oC. The presence of oleanane indicates the Cretaceous or younger source rocks. Good correlation on biomarker and isotopic data with the organic matter dispersed in Oligocene Menilite Beds, occurring at the top of the Carpathian flysch succession, allowed authors to identify them as source rocks for oils of the Lopushna field, which thus can be regarded as an oil family of the Outer Carpathians. The migration distance for both Lopushna oils and oils accumulated in the Carpathian flysch strata was similar. A number of sub-vertical dislocations, on which the subsided flysch strata occur at the same depth level with the Jurassic and Cretaceous rocks of the platform, can be assumed as possible migration pathways from the mature source rocks of the Oligocene Menilite Beds of Boryslav-Pokuttya, Skyba or Krosno units to the Lopushna type traps, which suggests the possibility of existence of other hydrocarbon accumulations of this type. The Lopushna field so far is unique containing this type of oil found in the basement of the Ukrainian Carpathian Foredeep.

We wnioskach podniesiono konieczność (potrzebę) wsparcia badań naukowych związanych z kompleksową oceną skutków wynikających z regulacji rzek. Zakres badawczy powinien obejmować badania naukowe na odtworzonych budowlach wodnych (tzw. modelach fizycznych) w połączeniu z modelowaniem układów (struktur) hydraulicznych wraz z wykonaniem obliczeń matematycznych dotyczących prognozowania skutków regulacji koryt rzecznych (cieków).
This work concerns the problem of flood control of rivers in the Ukrainian Carpathians. It points to the need of carrying out comprehensive river engineering altogether with the execution of the designed flood reservoirs, flood banks and hydraulic structures (river regulation structures). The conclusions indicate the necessity to support scientific research related to a comprehensive assessment of the effects of river engineering. The research should include scientific studies of reconstructed hydraulic structures ( so called physical ones) , as well as the modelling of hydraulic structures and mathematical calculations concerning the prognosis of the effects of watercourse engineering.

The origin of the olistostromes at the front of the Ukrainian Carpathian orogen is related to Miocene synsedimentary thrust movements of the Carpathian accretionary prism and to erosion of uplifted areas of the Boryslav-Pokuttya Nappe in the front of the accretionary prism. There are two olistostrome complexes. The first is the Lower Miocene Polyanytsya-Vorotyshcha Olistostrome with clasts of molasse and flysch deposits formed in a piggy-back basin on the inner part of the Boryslav-Pokuttya Nappe at the top of the accretionary wedge. This olistostrome is associated with the Sloboda Conglomerate derived from the fore-bulge at the foreland of the Boryslav-Pokuttya Nappe. The second one is the Middle Miocene Lanchyn Olistostrome with olistoliths of strongly deformed molasse deposits. These olistoliths were slid from the uplifted front of the Boryslav-Pokuttya Nappe. The Lanchyn Olistostrome was deposited at front of this nappe in a foredeep basin.

Opis:
Geochemical characteristics of 25 oils collected from Skiba Unit of the Outer Carpathians, Boryslav-Pokuttya Unit of the Carpathian Foredeep and their Mesozoic basement in the western Ukraine are presented in the paper. The first recognised oil family consists of almost all oils accumulated in the flysch sequence of the Outer Carpathians and the Carpathian Foredeep which have very similar geochemical characteristics. These oils were generated from Type II or II/III kerogen deposited in clastic sediments. They are low-sulphur and migrated short distances. Slight biodegradation processes are visible only in oils accumulated in shallow deposits in the Skiba Unit. Their source rocks are the Oligocene Menilite Shales from the Boryslav-Pokuttya Unit. Oils from the Kokhanivka and Orkhovychi deposits (the Mesozoic basement of the Carpathian Foredeep) constitute the second family. These oils are extremely heavy, high-sulphur and were generated from high-sulphur Type IIS kerogen deposited in the carbonate environment. The most probable source rocks for these oils are the Upper Jurassic strata. Oil collected from the Vola Blazhivska deposit (the Boryslav-Pokuttya Unit) shows intermediate parameters between the oil families described above. It is characterized by the presence of oleanane and high sulphur content. It was generated from the Menilite Shales containing high-sulphur kerogen. All oils were generated at an early stage or the peak of oil window.

Opis:
Near-surface gases were investigated in Starunia, where remains of mammoth and woolly rhinoceroses were discovered at the beginning of the 20th century. Samples were collected at 30 measurement sites, from 0.8, 1.6, 2.4, 3.2 and 4.0 m depths and analysed for their molecular and isotopic compositions. Most of the methane and all higher gaseous hydrocarbons accumulated within the near-surface zone are of thermogenic origin. The distribution of thermogenic methane and higher gaseous hydrocarbons in Quaternary sediments is variable and, generally, increases with depth. Microbial methane or a mixture of microbial and thermogenic methane also occurs at the near-surface zone. The presence of hydrogen and alkenes in the near-surface gases also suggests a contribution from recent, microbial processes. Helium of crustal origin migrated through the Rinne Fault and other tectonic zones located in the study area, and was subsequently dispersed during migration through the lithologically diversified Pleistocene and Holocene sediments. The high variability of the carbon dioxide concentration and stable carbon isotope composition at various depths in the near-surface zone is caused by its polygenetic origin (thermogenic, microbial, and oxidation of hydrocarbons and Quaternary organic matter), and also by its dissolution in water and oil during migration through lithologically diversified Pleistocene and Holocene sediments. Zones of thermogenic methane occurrence within Pleistocene sediments, dominated by muds saturated with bitumen and brines, provide the most favourable environment for preservation of large extinct mammals. It is likely that during the Pleistocene winters, when thick ice and snow covered the tundra lake and swamp, zones of outflow of brines, oils, helium, and thermogenic gaseous hydrocarbons had a higher temperature, which could have resulted in melting and cracking of the ice cover and drowning of large mammals. The most favourable conditions for preservation of large, extinct mammals probably still exists in the vicinity of sampling probe sites Nos 21, 22, 23 and 36. Zones of dominance of microbial methane concentrations are less favourable sites for preservation of extinct mammals, because this methane was generated within recent swamps and also within recent descending meteoric waters which infiltrated into Pleistocene and Holocene sediments. Older Pleistocene microbial gases have already escaped to the atmosphere.

Opis:
The unique nature of the Starunia palaeontological site, where near-perfectly preserved large mammals were discovered at the beginning of the 20th century, and incomplete knowledge on the development of palaeoenvironment in the Velyky Lukavets River valley in the Late Pleistocene and Holocene were the reasons for undertaking new comprehensive palaeobotanical and malacological studies. Starunia is also one of the sites bearing Pleistocene fossil flora, rare in this part of Europe. The results of plant macrofossil analysis show that in the Weichselian Middle Pleniglacial the landscape was dominated by steppe and tundra plant communities, being represented mostly by various grass and sedge species. Areas of higher humidity were covered with shrub tundra with Betula nana. The temperature requirements of taxa which are cool climate indicators show that the minimum July temperature amounted to at least 10°C. The record of Late Weichselian malacofauna confirms the dominance of an open landscape, mostly with steppe and steppe-tundra communities, as well as the presence of a dry, continental climate. At the beginning of the Holocene, an improvement of climatic and humidity conditions led to a fast local expansion of plant communities of the low and transition peat bog type, in the surroundings of shallow, periodically drying-up water pools. From the Middle Pleniglacial up to the present day, the area has been characterized by the presence of species tolerating an increased amount of salt in the environment. Their presence should be associated with natural brine effluences derived from Miocene strata in the bedrock.

Opis:
The unique nature of the Starunia palaeontological site, where nearly perfectly preserved large mammals were discovered at the beginning of the 20th century, and also the incompletely researched history of the Pleistocene vegetation of the region, provided the necessary stimulus to undertake further complex palaeobotanical investigations. The Pleistocene and Holocene sediments filling the Velyky Lukavets River valley are the object of this type of investigation. Both the succession of vegetation and radiocarbon dating indicate that the formation of biogenic sediments began in the Weichselian Middle Pleniglacial, in the Moershoofd interstadial, and lasted through the Hengelo/Denekamp Interstadial Complex and the Late Glacial and Holocene. Palaeobotanical investigations show the Middle Pleniglacial to have been characterized by an open, forestless landscape. Grassland steppe communities dominated with extremely high proportions of Poaceae, as well as Artemisia, Chenopodiaceae, and a number of herbaceous plant taxa. More moist places were occupied by dwarf shrub tundra with Betula nana, Alnus viridis, and Cyperaceae. Small changes in the character of the vegetation resulting from climatic oscillations made their mark through a slight increase in the proportion of tree-birches, fir and pine. The record of Late Weichselian plant succession in the Velyky Lukavets River valley also documents the dominance of open habitats with a preponderance of steppe and steppe-tundra communities and a dry, continental climate. Only with the beginning of the Holocene did an improvement in climate conditions lead to the rapid expansion of forest communities with a dominance of pine accompanied by fir, larch, and trees, which are more demanding in terms of temperature, e.g. elm, oak, lime, hornbeam and hazel.
