Opis:
The Upper Pleistocene loess-palaeosol sequence from the Kolodiiv section (East Carpathian Fore land) has been palaeomagnetically studied. Almost all samples displayed moderate to high positive palaeomagnetic inclinations and declinations en closed between 320° and 40°. How ever, one sample from the fossil soil of the last inter glacial pedocomplex (at 16.6 m pro file depth) was reverse magnetized and there fore can be correlated with the Blake Palaeomagnetic Event. Consequently that palaeosol can be related to (Oxygen Isotope Stage) OIS 5e1. An other sample from the Dubno 1 interstadial palaeosol demonstrated southern declination and significant lowering of inclination (up to 40°). This might be a record of the Laschamp Palaeomagnetic Event or of any Late Pleistocene palaeomagnetic excursion. The magnetic susceptibility and anhysteretic remanent magnetization data reflect the presence of several soils forming during the warm conditions of OIS 5 and the complex nature of the Eemian warming. Two palaeosols that developed between ca.115 ka and 120 ka indicate at least two climatic optima during the Eemian. High values of magnetic susceptibility (up to 300 Ą 10-6 SI units) noted in the middle of the section that contains slump deposits (9.5 m to 11m of depth) suggest that this material was derived from older soils of inter glacial type.

Opis:
The history of archaeological research on the Trypillian sites in the western regions of Ukraine can be subdivided into four stages, each of which is marked by certain achievements. The first explorations resulted in the discovery of new archaeological objects, which gave rise to the discussion about the interpretation of constructions and functions of the settlements. The questions related to chronology, periodization, and excavation methodology were discussed as well. However, this activity was irregular and spontaneous, and the materials of many sites were scattered over different museums of Europe. The later stages of research gave very important data about the material and sacral components of the Trypillian culture, as well as its development, ways of adaptation to natural conditions, relative chronology of the sites, and their distribution. In the last years, the systematic excavations conducted at the reference site of Bodaki shed an important light on the economic basics of Trypillia. They also gave new materials for reconstructing the connections between the north-western and central areas of the culture, and its connections with the coeval farming-herding cultures of Europe.

Opis:
In the 1950s, a settlement of the Funnel Beaker culture (FBC) was discovered on the Lysivka Hill in Vynnyky (Fig. 1), located in the centre of the West Ukrainian territory of this culture (Hawinskyj, Rybicka 2021). Currently, it belongs to a small group of FBC sites in Western Ukraine that have been excavated. The information presented by M. Peleshschyshyn, who conducted excavations in Vynnyky-Lysivka, regarding the relationship between the FBC community and the Tripolye culture (TC) was particularly interesting (see Rybicka 2017). He believed that Vynnyky recorded the coexistence of their population (Peleshschyshyn 1998a, 191). The burnt daub clusters discovered at that time could probably have been the remains of dwellings. The aim of the research carried out since 2016 was to verify the hypotheses of M. Peleshschyshyn (1998a) in the context of the FBC-TC relationship (Hawinskyj, Rybicka 2021) and to establish the date of the settlement usage in Vynnyky-Lysivka. Radiocarbon dating obtained for the samples from the features from the northern zone of the settlement, allow the researchers to be placed Vynnyky-Lysivka in the period 3500–3360 BC and synchronized with the third phase of the southeastern FBC group.

Opis:
The genus Diodora Gray, 1821 is widely represented in the Middle Miocene of the Central Paratethys with specimens usually attributed to D. graeca (Linnaeus, 1758) or D. italic (Defrance, 1820), well-known recent species of the Atlantic / Mediterranean Basin. In samples from the Upper Badenian of Western Ukraine we found two clusters of Diodora specimens, showing a similarity with these species, but a review of shell diagnostic characters using a statistical approach has revealed their clear conchological separateness. The first species from Varovtsi and Horodok is attributed herein to D. nodosa (Eichwald, 1830), whereas the second species from Maksymivka is described as a new species, D. stalennuyi sp. nov. We consider that these molluscs inhabited the Polish-Ukrainian marginal part of the Late Badenian Basin. Detailed descriptions of the protoconch and teleoconch morphology of the taxa involved, including SEM images, are presented.

Opis:
The Mykolaiv Sands are a huge lithosome of Middle Miocene (Badenian) age, accommodated within the Fore-Carpathian Basin in the Western Ukraine. Typically developed in the area of Opole Minor, it spreads across adjacent regions of Opole to cover an area of about 1300 km2. The varied sedimentary structures and ubiquitous burrows, indicate their development as a stack of sand shoals or related bodies, up to a few tens of metres thick, some of which temporarily reached sea level. Amidst the shoals, storm scours intermittently formed channel-like infills, some with residual lags at the base. The reversed density stratification and/or an increasing gravity gradient involved mass movements, some of which may have been triggered by seismic shocks focused at the shore or the adjacent hinterland of Podolia and Volhynia. Special attention is paid to the diverse fossils, all taphonomically filtered (aragonite shells and chitinous carapaces being lost), but which locally are mass-aggregated. They typify particular sand sets/bodies, to form allochthonous assemblages, some members of which (the cirripedes Scalpellum and Creusia, the shark Hemipristis, the ray Myliobatis) are newly recognized in the Ukrainian part of the Fore-Carpathian Basin. The others enrich considerably the faunal content of the Middle Miocene (Badenian) Paratethyan basins, either in terms of taxonomic diversity, or the eco-taphonomy of selected taxa (the starfish Astropecten, diverse echinoids). The whole faunal content of the Mykolaiv Sands may owe its profuse development to the global Middle Miocene Climatic Optimum of early Badenian age.

Opis:
The Zoloushka Cave belongs to a group of the largest gypsum caves in Western Ukraine (Bukovina region), developed in the middle Miocene (upper Badenian) evaporite series (Tyras Formation) on the SW periphery of the East European Platform. It is developed in the lower part of the evaporite series composed of gypsum, which is covered by a carbonate layer (Ratyn Limestone). The uneven upper surface of the gypsum at the contact with the limestone, the frequent occurrence of palaeokarst forms, and the presence of karstified fissures filled with allochthonous material indicate a sedimentation break between the gypsum and the overlying limestone. To support this thesis and to add new data on the age and palaeoenvironmental conditions of palaeokarst formation in the Bukovina region, palynological studies were carried out on material from the Zoloushka Cave. Palynofacies, sporomorphs and dinoflagellate cysts were studied. In total, over 70 sporomorph taxa and over 25 dinoflagellate cyst taxa have been identified in four samples collected from the filling of the palaeokarstic forms in the cave. The results of the analysis of sporomorphs and dinoflagellate cysts point to the formation of the palaeokarst during the sedimentation break that took place at the end of the late Badenian evaporitic cycle in the Western Ukraine region. The subsequent marine transgression led to the filling of the karst forms in gypsum with chemogenic carbonate material, precipitated from marine water (draperies) and with fine-grained, clastic material (pockets and fissures).

The presented scientific, theoretical and practical aspects of the topic are considered an important prerequisite for understanding the causes and results of the mass use of the deportation repressive tool in the intensive consolidation of Stalin’s totalitarian regime in “class hostile environment” and the consequences of such a policy for the western region development, particularly at modern stage, including the Ukrainian political nation-building and the independent Ukrainian state, which is now experiencing challenges and threats that are rooted in the totalitarian past. Stalinism, as a particular political regime, was established in the western regions of Ukraine at the final stages of World War II and can be defined as a kind of left extremist totalitarianism. The main components of the efficiency of the Stalinist totalitarian regime based on the mass use of political violence and terror through the branched structure of repressive secret police. Functions of the NKVS, NKVD, prosecutors, and courts followed the strategic objectives of Stalin’s totalitarian regime in a hostile social and national environment in Western Ukraine in the complex military and political conditions of the final phase of World War II. Effective and timely implementation of policy priorities of Stalinism in the region allowed to create an appropriate institutional and procedural system, which was based on the large-scale use of political violence and employed such characteristic tools as terror, repression, deportation.

Opis:
Reconstruction of burial and thermal history was modelled for the Mesozoic strata in the basement of the Polish and Ukrainian parts of the Carpathian Foredeep and in the marginal part of the Outer Carpathians. The 1-D modelling was carried out in profiles of the wells located in the area between Tarnogród and Stryi towns. In the Polish part, the modelling were performed in the profiles of the Księżpol 15, Lubliniec 9, Markowice 2 and Opaka 1 wells, and in the Ukrainian part in the profiles of the Chornokuntsi 1, Korolyn 6, Mosty 2, Podiltsi 1 and Voloshcha 1 wells. The geochemical characteristics of the Mesozoic stratigraphical horizons revealed that the best features of source rocks were present in the Middle Jurassic strata in the Polish part of the study area and in the Middle and Upper Jurassic strata in the Ukrainian part. Within these strata, the horizons of source rocks were distinguished and their quantitative evaluations were characterized. For these horizons, reconstruction of processes for hydrocarbon generation and expulsion were performed. The source rocks in the Polish part reached maturity only in the initial phase of “oil window”. However, the maturity achieved towards the end of the Upper Jurassic was insufficient to exceed the 10% threshold of the transformation degree for hydrocarbon generation. Therefore, the amount of generated hydrocarbons was minimal. Slightly higher maturity of organic matter in the Ukrainian part resulted in exceeding the thresholds of kerogen transformation and the initiation of hydrocarbon generation and expulsion processes. The process began after the deposition of thicker Miocene formations and developed even up to the main phase of the "oil window". The amount of the generated hydrocarbons reached ca. 150 mg/g TOC with an insignificant volume of expulsion.

Opis:
Quantity, genetic type and maturity of organic matter dispersed in the Lower Palaeozoic sequence from the Lower Cambrian to Silurian strata of the Polish and Ukrainian parts of the Carpathian Foredeep basement in the Tarnogród–Stryi area were evaluated based on the results of geochemical analyses of 475 rock samples collected from 45 wells. The best source rocks were found in the Silurian strata where the present total organic carbon (TOC) content is up to 2.6 wt%. They occur in the vicinity of Wola Obszańska, where the median of the present and the initial total organic carbon (TOC) contents in the individual wells amount to 0.98 and 1.6 wt%, respectively. The Cambrian and Ordovician strata have a poorer hydrocarbon potential and their present TOC content never exceeds 1 wt%. In all of the investigated Lower Palaeozoic strata, organic matter is represented by the oil-prone Type-II kerogen deposited in anoxic or sub-oxic conditions. The maturity of source rocks ranges from early mature (the initial phase of the low-temperature thermogenic processes) in selected zones of the Silurian strata in the vicinity of Wola Obszańska, through the middle and the final phase of “oil window” in the Ordovician and Cambrian strata in the Polish part of the study area, to the overmature stage in the Ordovician strata in the south-eastern part of the study area (Ukraine).

Opis:
W niniejszej publikacji zostały przedstawione współczesne tendencje przestrzennego rozwoju komunikacji trolejbusowej w dużych miastach zachodniej Ukrainy. Badanymi miastami są Lwów, Łuck, Równe, Tarnopol, Iwano-Frankiwsk i Czerniowce. Trolejbusowe systemy komunikacji tego regionu charakteryzują się bogatą historią i strukturą przestrzenną sieci. Przeważa tu radialne planowanie sieci, co powoduje problemy w ich eksploatacji. Linie trolejbusowe w tych miastach mają długość od 64 do 119 km, ale obecnie trwa ich rozbudowa przeważnie do nowo powstających osiedli mieszkaniowych. W większości miast funkcjonuje 8-10 linii trolejbusowych, które pokrywają główne ciągi komunikacyjne. W każdym z miast eksploatuje się od 48 do 89 sprawnych trolejbusów przeważnie produkcji zagranicznej. Producentem większości z nich jest czeska Skoda. W ostatnich latach zostały zakupione pojazdy używane z krajów UE. Tabor miejskich systemów trolejbusowych w zachodniej Ukrainie jest mocno wyeksploatowany, a średni wiek pojazdów wynosi od 20 do 28 lat. W artykule przeprowadzono szczegółową analizę uwarunkowań rozwoju sieci trolejbusowych i scharakteryzowano tabor w każdym z sześciu badanych miast. Głównym problemem rozwoju tych systemów jest niedostateczne finansowanie. Perspektywy rozwoju wiążą się z rozbudową sieci połączeń, zakupem i modernizacją taboru trolejbusowego oraz wprowadzeniem nowoczesnych rozwiązań technologicznych.
In this article, the modern spatial trends of development of trolleybus transport in the big cities of the western Ukraine are considered. The cities under investigation are the following: Lviv, Lutsk, Rivne, Ternopil, Ivano-Frankivsk and Chernivtsi. The trolleybus systems of this region have been developed in similar circumstances as the past. The radial planning of network prevails here, which causes some inconveniences for exploitations. Trolleybus lines in these cities have lengths of 64 to 119 kilometers, but in the future, their development will last mainly in the inhabited microregions. In most cities, 8-10 trolleybus routes that cover main transport highways functioned. In each city, there are 48 to 89 operating trolleybuses, mainly imported products (majority – Czech Skoda). In recent years, massive amounts of used machines from the countries of the EU were bought. The rolling stock of the systems of trolleybuses in big cities of West of Ukraine is exhaust, and middle age machines hesitates from 20 to 28 years. The article analyzes the determinants of the trolleybus network development. The author characterizes the rolling stocks in each of the six cities which are under investigation. The main problem of the development of these systems is insufficient funding. The prospects of the development are related to the expansion of the network of connections, the purchase and modernization of trolleybus rolling stock and the introduction of modern technological solutions.

Opis:
For a long time, outcrops at Potelych, Nahoryany and Lviv in western Ukraine have been of special interestfor Campanian andMaastrichtian (Upper Cretaceous) palaeontology and biostratigraphy. An overview of studies devoted to these classic sites is presented, including an early account of the locality of Nahoryany in a Polish newspaper, dated 1843. The biostratigraphic position ofthese successions is reviewed, based on recent progress in studies of inoceramid bivalves and ammonites. The succession at Potelych, from where a unique land flora was described at the beginning of the 20th century, represents the upper Campanian “Ino- ceramus” costaecus Zone. The Nahoryany opoka, the source of rich fossil collections that were sent to many European museums in the 19th century, belongs to the lower Maastrichtian Endo- costea typica and Trochoceramus radiosus zones. The so-called Lviv marls correspond to the lower upper Maastrichtian Spyridocera- mus tegulatus Zone. The giant scaphitid ammonites Hoploscaphites quadrispinosus and Acanthoscaphites tridens s. str from Potelych and Nahoryany corroborate the inoceramid-based dating of these successions.

Opis:
According to common interpretations, two narrow crustal blocks are supposed to occur on the south-western edge or in the foreland of the East European Craton. The first one, bounded on the NE by the Nowe Miasto-Radom-Rava Ruska fault system, and on the SW by the Holy Cross Fault, stretches NW-SE from the Łysogóry-Radom region in Poland to the Rava Ruska Zone in Ukraine. The second one, bounded on the NE by the Holy Cross Fault, and from the SW by the Chmielnik-Ryszkowa Wola–Krakovets fault zone, is thought to tie together the Kielce area of the Holy Cross region with the Kokhanivka Zone in Ukraine. Both these blocks may have formed in connection with the development of regional listric faults during Precambrian asymmetric stretching of the Baltica continent, and were part of the marginal zone of the East European Craton. The sedimentary development of the blocks can be comparable to the Blake Plateau off the Florida coast. Both the Paleozoic sections and tectonic deformation styles in the Polish and Ukrainian segments of these blocks are different. Paleozoic tectonic structures of the Holy Cross region have a southern vergence, while the Paleozoic rocks of the Rava Ruska and Kokhanivka regions in western Ukraine are thrust towards the NE. This demonstrates the different tectonic evolution of the Paleozoic succession between the Holy Cross region and western Ukraine, and makes questionable the genetic relationships between these two regions. In this situation, the tectonic blocks of the foreland should be considered heterogeneous. Structural-facies evidence suggests that the SW boundary of the East European Craton should be moved at least to the Chmielnik–Ryszkowa Wola-Krakovets fault.

Opis:
In south-eastern Poland and western Ukraine, the Outer Carpathian orogen and the Carpathian Foredeep developed in the foreland of the East-European Platform (Baltica). The area consists of a number of tectonic units included in the Trans-European Suture Zone (TESZ): the Łysogóry–Radom and Małopolska blocks in the territory of Poland, and the Rava Rus’ka Zone, Kokhanivka Zone and Leżajsk Massif in the Ukraine. The development of the TESZ began in the (?Middle) Late Neoproterozoic and was associated with rifting processes taking place along the western edge of the East-European Craton (Baltica) during the break-up of the Rodinia/ Pannotia supercontinent. The passive margin of Baltica evolved into the TESZ during collisional and/or strike-slip movements. In the TESZ (Małopolska Block and Leżajsk Massif), Ediacaran flysch-type siliciclastics were affected by weak metamorphism and folding during the Cadomian orogeny. The development of Cambrian deposits in the East-European Craton, Łysogóry–Radom Block, northeastern part of the Małopolska Block (Kielce Fold Belt) and in the Rava Rus’ka and Kokhanivka zones was associated with the post-rift thermal subsidence. Tectonic movements (so-called Sandomierz phase), which occurred probably due to an oblique collision of the Małopolska Block (included into the passive margin of Baltica) and the East-European Craton during late Middle Cambrian to Late Cambrian (possibly also Early Ordovician) times, resulted in the following: (1) development of stratigraphical (?erosional) gaps in the Middle and Upper Cambrian sections of the Lublin–Podlasie slope of the East-European Craton and the Kielce Fold Belt in the Małopolska Block; (2) intense tectonic subsidence of the Łysogóry–Radom Block during the deposition of Middle and Upper Cambrian sediments; (3) development of compressional folds in the Lower Cambrian to lower Middle Cambrian deposits of the Kielce Fold Belt on the Małopolska Block. Ordovician–Silurian series were deposited in a typical flexural foredeep basin, in which subsidence and deposition rates accelerated during Late Silurian (Ludlow–Pridoli) and Early Devonian (Lochkovian) times. It is postulated that the present position of the Małopolska Block relative to the Łysogóry–Radom Block and East-European Craton resulted from post-Silurian dextral movements between the Małopolska Block and the East-European Craton. Devonian–Carboniferous deposits occur only in the Małopolska Block located in the Variscan foreland. The Middle-Late Devonian and Early Carboniferous shallow-marine carbonate platforms developed under an extensional regime. The siliciclastic Upper Visean–Lower Namurian A Culm series were deposited in the flexural Variscan foreland basin. During the Late Namurian A, the Małopolska Block was uplifted in response to the build-up of compressional foreland stresses. During post-Carboniferous times, the Precambrian and Palaeozoic deposits were subject to erosion and restructuring during the Alpine orogeny.

Opis:
The Upper Jurassic–Lower Cretaceous carbonate sediments developed in a narrow, Ukrainian part of the basement of the Carpathian Foredeep show high facies diversity. Based upon thin section studies, the authors identified eleven principal microfacies varieties. Three main stages of development of carbonate platform were distinguished: (i) Oxfordian–Early Kimmeridgian, (ii) Kimmeridgian–Tithonian, and (iii) Berriasian–Valanginian. The Oxfordian sediments are rather thin and represent both the outer and inner, distally steepened ramp facies. In the Late Kimmeridgian and, mainly, in the Tithonian, the intensive growth of rimmed platform took place with distinct zones of peritidal, margin barrier and platform slope, bearing calciturbidite facies. Development of the rimmed platform was controlled by synsedimentary tectonic movements along faults rejuvenated southwest of the Holy Cross Mts. Fault Zone. In the Berriasian–Valanginian, the dominant process was sedimentation onto not-rimmed platform controlled by small sea-level changes. Both the facies development and literature data indicate that the Late Jurassic sedimentation in the Ukrainian part of the Carpathian Foredeep basement shows considerable differences in comparison to that of the Polish part. In the studied successions, large Oxfordian microbial-siliceous sponge reef complexes, known from the Polish part of the Carpathian Foredeep basement and other areas in Europe, were rare. In the study area carbonate buildups were encountered mainly in the intervals representing the Upper Kimmeridgian–Tithonian where small, microbial-sponge and microbial-coral biostromes or patch-reefs were formed. Their growth was presumably restricted to a narrow zone of the upper slope, close to ooidal-bioclastic margin platform facies. In the Polish part of the Carpathian Foredeep basement, the Late Jurassic sedimentation took place on a vast, homoclinal ramp while in the Ukrainian part it proceeded on a narrow, distally steepened ramp and rimmed platform with distinct marginal platform barrier. Similar platform facies distribution in both regions appeared mainly in the Early Cretaceous, although with some stratigraphical differences. The facies distribution of the Upper Jurassic sediments was closely controlled by the block structure of the basement and by orientation of the main, transcontinental Holy Cross Mts. Fault Zone, which supports the opinion on its activity in the Mesozoic era. The Ukrainian part of the Carpathian Foredeep basement located over the Palaeozoic Kokhanivka Block, between the Krakovets and Holy Cross fault zones, includes predominantly the slope, marginal and inner platform facies. Facies observed over the Palaeozoic Rava Ruska Block (south-western part of the East-European Platform), between the Holy Cross and Rava Ruska fault zones, represents mainly the inner platform and the peri-shore deposits.
