Tirasiana Palij, 1976 is a genus of radially symmetric Vendobionts, which were preserved as a positive hyporelief of two superimposed discs. Tirasiana are found in the Vendian deposits of the Podolian Dnister area, the White Sea area and the Urals. For better understanding of the nature and lifestyle of Vendian biota, imprints of the Tirasiana were investigated by statistical methods. Sampling of 29 specimens of Tirasiana was studied. To test the hypothesis about the allometric growth of Tirasiana, two features were studied, the diameters of the outer and inner discs. As a result of the study, it has been established that the relationship between internal and external diameters of the imprints is almost ideally isometric, which means that there is no evidence for relation between Tirasiana and Cnidaria. The distribution patterns of these features were analyzed and the assumption about their normality was tested. Histograms of their distribution and empirical additional cumulative distribution functions were constructed. Based on the assumption of the constant growth of Tirasiana throughout onthogenesis and the proportionality of the linear size and individual age, the cumulative distribution functions may be considered as survival curves in the sampling of specimens of Tirasiana and may be analyzed by standard methods accepted in ecology. If we accept this assumption, then the survival curve of the first type is characteristic of the Tirasiana, which corresponds to the increase of probability of their death with the increase of individual age. The studied taphocenosis was formed as a result of accumulation of terrigenous material, which came from the nearby land that was not stabilized by vegetation. This terrigenous sediment buried benthic sublittoral communities regularly. The heterogeneity of the sampling of specimens can be explained by the presence of "survival stations", well-protected parts of the palaeobasin (overhanging rocks, baybar, etc.). As a result, in such places Tirasiana could attain much larger size.

The article summarizes information about the Ilyinets structure exclusiveness, highlights its geological, mineralogical and geochemical, landscape and historical and cultural features. This topic relevance is due to the issues of preserving land resources within the cosmogenic landscape and assessing the state of the environment. The assessment of the ecological state of the study area made it possible to outline the threats to the environment within the Ilyinets crater. Among the natural origin threats, exogenous processes (geological work of surface waters, wind erosion, weathering) stand out, as a result of which ravines and gullies are formed; there is soil degradation, landscape changes and the like. Anthropogenic pressure carries two types of threats: unintentional actions to cause harm; and willful harm. The anthropogenic activity sometimes coincides with natural processes, raising their harmful consequences. In the work, stresses, critical, supercritical and catastrophic states of the environment of the Ilyinets impact structure are indicated. The characteristics and ranking of environmental threats are presented. The data obtained allow us to represent the ecological state of the Ilyinets crater as close to supercritical. We consider the administrative approach to the geological natural monuments allocation to be the main problem of the Ilyinets impact structure preservation. In order to stop the deterioration of the ecological state and preserve the unique natural structure, soils, landscapes and biogeodiversity of the territory, it is proposed to create the Ilyinets National Natural Park together with the existing botanical reserves, since increased ravine formation and intensive agricultural activities will lead to the land and forest resources degradation, impoverishment of biodiversity, as well as the loss of the recreational and tourist attractiveness of the region as a whole.

Paper concerned the research of elastic and electric properties of deep-seated consolidated terrigenous rocks of Carboniferous period of the Central graben of the Dnieper-Donetsk depression (DDD). The purpose of the research was to study the petrophysical parameters of the consolidated reservoir rocks, as the basis of the integrated analysis of their physical properties. Such electric and elastic parameters of rock samples as resistivity and formation resistivity factor, formation resistivity enlargement factor, velocities of the P-waves and interval (transit) time have been studied. The correlation analysis has allowed establishing a series of empirical relationships between resistivity and formation resistivity factor, and between porosity and formation resistivity factor in atmospheric and reservoir conditions. The correlation relationships of the resistivity with formation resistivity factor manifest itself in linear function. Physical modeling of reservoir conditions allows adapting the values of electrical parameters obtained in atmospheric conditions to parameters of rocks in reservoir conditions. Laboratory acoustic study of siltstones and sandstones managed to establish correlation relationships of: velocities of the P-waves and interval (transit) time with density and porosity in atmospheric conditions; velocities of the P-waves in atmospheric and reservoir conditions; velocities with porosity in reservoir conditions. The dependence of the velocities of the P-waves in atmospheric and reservoir conditions for the studied rocks manifest itself in linear function. Physical modeling of reservoir conditions allows adapting the values of elastic parameters obtained in atmospheric conditions, to parameters of rocks in reservoir conditions. The correlation relationships of the electric and elastic properties with reservoir properties of siltstones and consolidated sandstones which were obtained in laboratory petrophysical research should be at the basis of preliminary interpretation of geophysical data on new areas of the Central graben of DDD.

The current version of the Tax Code allows for misinterpretation of the interpretation of the term "primary processing of mineral resources". In particular, the tax authorities believe that the primary processing of mineral raw materials includes magnetite concentrate, which in this case is subject to taxation. That is, a number of mining and processing enterprises have faced the problem of double taxation, which threatens significant financial losses. Accordingly, this led to the choice of topic for writing this article, the purpose of which is to conduct research on changes in mineral forms of minerals (iron ore), their aggregate-phase state, crystal chemical structure during production processes at mining, crushing and concentrating production of Kryvyi Rih mining and processing enterprises, and establishing at what stage of production the primary processing of minerals for the purposes of rent taxation is completed and whether the position of enterprises on limiting primary processing by the stage of fragmentation meets the requirements of the Tax Code of Ukraine.

Geological education is the basis for training specialists in the study of natural resources. The rational use of subsoil is the basis of the economic development of Ukraine, especially in the conditions of the energy transition. Educational institutions provide a wide range of disciplines for the geological training of students. Participation in international societies contributes to getting additional knowledge. The distribution of professional societies within institutions and enterprises is world practice in many countries. There are several geological associations that cooperate with Ukraine in the geologic sciences. The student section of the Society of Exploration Geophysicists (SEG) was established at Taras Shevchenko National University of Kyiv at the Department of Geophysics twenty years ago. The introduction to new features was interesting and useful for students and teachers. Thanks to SEG programs, students received new computer equipment, geophysical literature, educational courses, attendance of lectures, international participation in symposia, possibility of organizing field camps, getting of scholarships, etc. The field of activity of the SEG Kyiv student chapter covers reports on its work at international conferences and educational institutions, the invitation of specialists of the geological industry, participation in geological quizzes and competitions among foreign students, conducting geophysical studies, etc. Members of the SEG section organized international geoscience investigations in various regions of Ukraine. The geophysical surveys were conducted to study ancient buildings in Kamianets-Podilskyi, a gypsum Verteba cave and paleovolcanoes near Uzhgorod. 49 students from 11 countries participated in the field camps. Local studies of pipelines were carried out by geophysical methods near the building of the ESI "Institute of Geology" (Kyiv) and on Totoha Mount, located in Kyiv region. Students performed magnetics, electrical resistivity tomography (ERT), surface seismic exploration, ground-penetrating radar (GPR), geodesic measurements and surveys UAV. The student chapter activity was presented at its meetings, with more than 50 reports. For 20 years, more than 100 students were members of the SEG section, which has been the basis for the AAPG and EAGE faculty circles. The SEG Kyiv student chapter is recognized as the best one in 2018. The geophysical section SEG has made a significant contribution to the spread of geological knowledge and the presentation of Taras Shevchenko National University of Kyiv internationally.

The article provides an inventory of geoparks from the list of the UNESCO Global Geoparks Network. It is noted that geoparks as important tourist attractions have been the subject of scientific attention of many authors, but the data presented in these publications are outdated and can not claim to be relevant to the current state of the geoparks network, as it is quite dynamic and changes every year. The research of the chosen topic in the scientific domestic and foreign literature is characterized. The insufficiency of the tourism research of the UNESCO geoparks system is pointed out. The structural-territorial analysis of the distribution of objects is performed: absolute and relative indicators of the number of objects by macroregions are established. A cartographic model of the distribution of objects on the planet is presented. Monitoring of a specific set of geotourism attractions within each of the geoparks is done taking into account the following thematic types: geological and geomorphological (geological and geomorphological formations - the mountains, intermountain basins and gorges, craters and cones of volcanoes, river valleys, deltas and canyons, lakes, waterfalls, sea coasts, deserts and aeolian, glaciers and glacial, karst and pseudo-karst landforms, geological forms and phenomena - the minerals, rocks, structural and tectonic formations, paleontological fossils, geothermal phenomena; geological and geomorphological processes - volcanic eruptions, geyser explosions, avalanches, coastal processes on sea and lake coasts, melting glaciers, dune movements, erosion processes); industrial (the open and underground mine workings, clay and sand quarries, pits, exploratory shafts, drain lines, rock dumps, tunnels, catacombs, surface and underground military objects, engineering and geological activities, construction of tunnels, construction of roads and highways, use of geothermal water); cultural and cognitive (works of material culture are different buildings made of natural materials and the elements of their arrangement, stone pyramids, rock cities and temples, the stone artefacts, the stone elements of urban infrastructure, the works of art, jewellery, museum and other expositions, open-air expositions, such places of fossils, supporting stratigraphic sections, places of minerals and rocks location); tourist and infrastructural attractions (availability of the geopark for the access by several types of transport, several tourist accommodation options, currency exchange offices, recreation facilities, parking lots, places for tents; Tourist Information Centres; marked tourist routes for the needs of several types of tourism (cycling, green-, caving, water- tourism); marking of tourist attractions (information stands.

The integrated geological, geophysical, and GIS methods for the overall assessment of the geological hazards within the urbanized environment were considered. The principal gap in the understanding of the geologically hazardous areas in Ukraine (landslide, soil erosion, pollution, etc.) is the lack of information about the properties of rocks and soils as well as their interaction with the past and present natural and anthropogenic formation. The study area is the landslide activation territory of Lysa Gora in Kyiv, Ukraine (Golosiivsky district). The slope has the conditional stabilization. At the same time the landslides provide the real dangery to the infrastructure facilities. One of the examples is the deformation of the railway along the Stolychne Highway. Landslide susceptibility data have been collected. The proposed methodology consists of the geological, geophysical, thermography, and remote sensing. This methods provide the possibility for the monitoring of landslides at the model areas in Kyiv region. The electrical resistivity tomography at the Lysa Gora identified two local zones of activation of landslide displacements, which are located in the range of depths of 3-8 m from the ground surface. The random distribution of the soil magnetic susceptibility and frequency dependence of the magnetic susceptibility both on lateral and verical line (soil genetic horizons) identified the presence of the displacement, redistribution and deposition of the soil and underlaying rocks. All the mentioned factors are in the genetic relation to the soil erosion and initial landslides.

The investigations of accumulative-sand deposits of the Black Sea coastline on the area from the village Liman (Katranka spit) to the village Karolina Bugaz (Odessa region) have been carried out. The length of the coastal line in the study area is close to 85 km. There are a lot of beach areas: spits, beach breaks, beaches on the shoreline. 35 samples were taken and analyzed from all types of beach depressions by the same methodology during the summer period. The sampling was carried out at all accessible for sampling places of beach deposits from the middle part of the near-shore beaches (between the water level and the shore) and at a distance of 5–7 m from the water edge on the headlands and spits in the period when there are no storms. For this purpose we used standard plastic containers with a capacity of 1 liter. The samples were taken from a depth of 30 cm from the surface with a stripping area of 30×30 cm. At each point the description of the coastal zone structure and the character of beach deposits were carried out, which were recorded in the logbook and were connected to the coordinates by GPS system. Granulometric and mineralogical analysis was carried out. It was determined that fractions 0,25–0,5 mm prevail in the granulometric composition among all types of beach deposits, which makes 66 %, and 0,1–0,25 mm – 30 %. In the smallest quantities there are coarsegrained and aleuro-pelitic fractions. The main places of localization of drilled-grained psammite and aleuropelite fractions are the areas with low influence of coastal tidal processes. However, during the periods of increased hydrodynamic activity (spring-autumn), additional resuspension of material takes place, which leads to displacement of other fractions from the deposits and their transfer to the sea side. Beach sediments are 90–95 % quartz. Others are calcite, feldspar, technogenic substances. Ore minerals are represented by magnetite, lignite spheroids, ilmenite, acerbic garnets, stavrolite, actinolite. The main sources of terrigenous material for the formation of beach deposits are the underwater bench, the Dniester river runoff, and coastal abrasion. Decisive in the distribution of sediments is the direction along the coastal current in the direction from Odessa city towards the delta of the Danube

Magnetic minerals form or alter in the presence of hydrocarbons, making them a potential magnetic proxy for identifying hydrocarbon migration pathways. We concentrate in the precision magnetic mineralogical analyzes to understand what magnetic minerals in soil from the hydrocarbon fields are responsible for the magnetic signal. To illustrate the results of our studying, we consider the study area of the hydrocarbon deposits near the village Balabanivka, Bogodukhiv district, Kharkiv region. A collection of soil samples is represented by deep medium-humus chernozems. The thermomagnetic analyzes, hysteresis parameters, and isothermal remanent magnetization curves (IRM) were studied for the samples collected near the well (point PR 28) and at the area located out of the hydrocarbon influence zone (point PR 0403). To study the thermomagnetic parameters, different types of the magnetization and magnetic susceptibility (MS, χ), and hysteresis loops we used the Variable Field Translation Balance (VFTB) instrument. The results are confirmed by the highest values of the gas geochemical parameters. The MS variations at temperatures ranging from 200 to 400 ˚C may reflect the presence of either iron sulphides or maghemite. The magnetite occurs for all soils. The wasp-waisted hysteresis loops identified either a mixture of two magnetic minerals (magnetite and hematite) and the admixture of the superparamagnetic and larger grains of the same minerals.

The article is devoted to the search and exploration of hydrocarbons deposits, which is a crucial and complicated geological task and requires the large bulk of initial data and significant intellectual efforts of geologists. In this regard, the urgent problem is to ease the working conditions of experts and improve the accuracy of forecasting the oil and gas potential of subsoil areas through the use of novel digital methods of heterogeneous data integration and interpretation. The paper proposes a new method to form predictive estimates of the oil and gas content of subsoil areas via combining geological, ground-based parametric, and satellite information. As the mathematical basis of the method, the means of Dempster-Shafer's theory of evidence are used, which makes it possible to combine data from different sources, proceed with incomplete and inaccurate data, etc. Most of the procedures that make up the body of the method are presented in the form of algorithms, which simplifies its technologization. The final information product of the proposed method is a map with the distribution of probabilistic estimates of oil and gas prospects of subsoil areas within a given study area. The developed method is implemented in software and tested at the Vostochno-Rogintsovskoye oil field. The test results indicated its fairly high efficiency.
