The black shale complex, which is organic carbon-bearing and characterized by syngenetic, epigenetic sulphidation and intense metamorphism in the Duruja structural-forma- tion zone of the southern slope of the Greater Caucasus, is the focus of geologists’ attention due to the mineralization areas, which are rich in significant non-ferrous, noble, radioactive metals, rare and rare earth elements. In order to determine the prospects of noble, non-ferrous, radioactive metals, rare and rare earth elements of the black shale of the Aghlig-Filfilli mineralization area of the Duruja zone, it is necessary to determine the mineralogical composition of the ores of the area, to study the textural-structural characteristics and to clarify whether the rocks of the zone are a source of complex ore raw materials. The object of the work is the mineragraphic and petrographic study of the numerous samples col- lected from the Aghlig-Filfilli mineralization area during the field expedition before the PhD admission period, during my post-graduate studies and currently in order to solve various important mineralogical and petrographic problems. In order to investigate the textural-structural characteristics and mineral types of the ores of the Aghlig-Filfilli mineralization area, thin sections and polished sections made from the samples were studied with the help of «Carl Zeiss» and «Polam-312» microscopes in transmitted and reflected rays. The composition, surface area and morphological characteristics of the monomineral samples were studied by the electron microscope «SEM». Accurate diagnosis of some minerals was carried out based on the results of their X-ray diffractometric analysis. According to the results of the research, the ores of the Aghlig-Filfilli mineralization area were formed in 3 stages: syngenetic, epigenetic and rem- ineralization as a result of strong metamorphism of syngenetic formations. At the same time, the origin of the ores of the Aghlıg-Filfilli mineralization area was studied. According to the results of the research, it was determined that epigenetic mineralization in contact with Aralig and Zangi deep faults in the north and south of the Aghlig-Filfilli area is of magmatogene origin (δ34S=1.6-4.6), and synge- netic mineralization in the black shales towards the center is of biogenic origin (δ34S= -18 – -22.6).

The article reveals the mutual influences of the geography of small towns (mistechka) and rural settlements in Ukraine and the system of administrative-territorial organization at the middle and lowest levels. Based on the statistical analysis, it was concluded that the location of very small cities, urban-type settlements (selyshchа miskoho typu) and villages is significantly differentiated by regions of Ukraine, taking into account the historical-geographical and natural-geographical prerequisites, the level of urbanization and industrialization, as well as differences in the demographic situation. The study proved that before the administrative reform, the small towns of Ukraine played an important role in the organization of the middle link of the administrative territorial system, being the centers of most districts, but as a result of the reform, their administrative importance in the district division became minimal. At the same time, almost half of the small towns became centres of united territorial communities. The author concludes that the loss of the status of medium-sized administrative units by towns could be compensated by transferring a significant part of the functions of regional authorities to new administrative districts, and most of the functions of former district centres to the centres of low-level territorial communities. For this purpose, it is necessary to create appropriate socio-economic conditions for the small towns-centres of new territorial communities to perform all the functions of serving the population of nearby settlements. It was concluded that such changes in administrative powers can ensure, in general, a shift in the weight of socio-economic life deep into the territory, which is necessary to overcome intra-regional disproportions in the development of the economy and the social sphere. The proposition that the structure of rural resettlement also influenced the territorial organization of local self-government in rural areas in different ways at all times was conceptually substantiated.

This study was conducted within the Zambezi River Basin to ascertain the bathymetry and sedimentation of selected reservoirs, evaluate their seasonal hydrological regimes, pinpoint the causes of reservoir siltation, and determine how the bathymetry and siltation impacted water-related industries and policy choices. Hydrological field measurements using a hydrographic survey boat, document studies, and interviews were used to collect the data. The 3D spatial analyst tools in ArcGIS 10.3 and hypsometric curves were used to analyze bathymetric data. Thematic analysis was used to analyze qualitative interview data. Findings indicated that sedimentation was a problematic phenomenon spatial-temporally and, it triggered a significant decrease in the storage capacities of the reservoirs. The study noted that catchments with small reservoirs were vulnerable to severe water stress, particularly from July through the beginning of the next rainy season in December. Over 90% of the local population and water-related industries were facing substantial risks of economic water shortages and may continue to face more water challenges amidst escalating climatic changes. The problem could be addressed by coping mechanisms such as alternative livelihoods, water harvesting, and water shedding. This study proposes an Integrated Water Resources Management Framework, which may help incorporate water education to bring about behavioural change against drivers of sedimentation. The proposed sediment and water resources management model serves as a multidisciplinary and transdisciplinary tool that could be used to address siltation concerns. This work has also shown the significance of bathymetric surveys of small reservoirs as a basis for policy context and regulations on managing water resources.

Shipwreck timbers (n=27) from the Spanish galleon Santo Cristo de Burgos, also known as the Beeswax Wreck (lost in 1693), are examined for origins of multiple, simultaneous rockslide burials that protected and preserved the timbers on an intertidal wave-cut platform in the small Smuggler Cove in the Northern Oregon coast. The rockslides (n=3–4) that buried the shipwreck timbers are compared to nearby historic rockslide analogs to better establish the mechanisms of boulder distributions on the wave-cut platform. Large boulders (n=20), generally ≥1.0 m intermediate diameter, in the North Smuggler Cove (NSC) timber burial site were measured for estimated mass (1–41 t) and alongshore distribution below small gullies that routed the boulders to the wave-cut platform from overlying short (~100 m distance) but steep hillslopes (40–60% gradient). The multiple independent rockslides in the NSC site, dated to ~300 years by the buried Beeswax Wreck timbers, showed catastrophic, simultaneous activation by a widespread trigger. Anomalous rainfall and/or storm wave attack are unlikely mechanisms for these rockslide activations due to 1) hillslope protections from extended-upslope surface water discharge and 2) sea cliff protection from direct storm wave impacts. The most likely widespread trigger for rockslide activation in the NSC site is seismic ground shaking from an earthquake in the Central Cascadia subduction zone. Modern storm wind velocities (>10 s-1 sustained velocity and 170–225° bearing) and storm surge generated rip currents (≥0.5 km offshore distance) indicate that Beeswax Wreck timbers could have been transported north (1–10 km) to Smuggler Cove, within several winter seasons after the breakup of the Santo Cristo de Burgos. The most likely seismic trigger that could have activated the multiple rockslides in the NSC site, shortly after the brief accumulation of shipwreck timbers on the narrow, intertidal wave-cut platform in Smuggler Cove, is the 1700 Cascadia great earthquake (Mw~9.0). Additional sea cliff rockslide sites (n=8) in the central Cascadia margin are suggested for further investigations of seismically activated slope failures by the 1700 Cascadia great earthquake.
西班牙大帆船圣克里斯多·德·布尔戈斯的沉船木材(n=27)，也被称为蜂蜡残骸(1693年丢失)，在俄勒冈州北部海岸的小走私者湾的潮汐间波浪切割平台上，研究了多个同时发生的岩石滑坡埋葬的起源，这些埋葬保护和保存了木材。将掩埋沉船木材的岩石滑坡(n= 3-4)与附近历史上类似的岩石滑坡进行比较，以更好地建立波浪切割平台上巨石分布的机制。在北走私者湾(NSC)木材掩埋地点，测量了大石块(n=20)，通常中间直径≥1.0 m，估计质量(1-41 t)和沿海岸分布在小沟壑下，这些沟壑将巨石从上覆的短(~100 m距离)但陡峭的山坡(40-60%坡度)引导到波浪切割平台。在国家安全委员会遗址的多个独立的岩石滑坡，通过埋藏的蜂蜡残骸的木材可以追溯到300年前，显示出由一个广泛的触发因素同时发生的灾难性的激活。异常降雨和/或风暴波攻击不太可能是这些岩崩激活的机制，因为1)山坡保护免受延伸的上坡地表水排放的影响，2)海崖保护免受风暴波的直接影响。在国家安全委员会地区引发岩石滑坡的最可能的广泛触发因素是中部卡斯卡迪亚俯冲带的地震引起的地面震动。现代风暴风速(>10 s-1持续速度和170-225°方位)和风暴潮产生的离岸流(离岸距离≥0.5公里)表明，在Santo Cristo de Burgos解体后的几个冬季，蜂蜡残骸的木材可能被向北(1-10公里)运送到Smuggler Cove。1700年卡斯卡迪亚大地震(Mw~9.0)是在走私者湾狭窄的潮间带波浪切割平台上短暂堆积沉船木材后不久，最有可能引发NSC现场多重岩石滑坡的地震触发器。建议在中部卡斯卡迪亚边缘的其他海崖岩崩地点(n=8)进一步研究1700年卡斯卡迪亚大地震引起的地震诱发的边坡破坏。

In the Northern iron-ore district of the Kryvbas basin, mining of deposits of poor magnetic ores is underway in two quarries – Pervomaiskyi and Hannivsky. Oftentimes, their mine contours contain low-valuable or unusable magnetite-silicaceous quarzites of containing ferrous and slate horizons. As a result, excavated ore mass contains ores and partly containing rocks of various mineral and chemical compositions and physical and technical properties. This caused diversity (15 mineral kinds) of the compositions of ores mined from the both deposits. Variability of mineral compositions of ores and rocks is due to manifesta- tions of numerous geological processes such as sedimentation, metamorphism, tectogenesis, metasomatism, supergene, etc. Various mineralogical, geochemical courses of the processes resulted in variability in physical, technical characteristics of ores and containing rocks, and this, in turn, caused various stability of rock masses during drilling-explosive works and mining. Stability of pit walls of the quarries of iron-ore deposits of the Kryvyi Rih basin is a sharp issue for mining enterprises. Solutions to those issues have been analyzed in various aspects. A number of factors take effects on the indicator of stability of rock masses within deposits, particularly mineralogical, geochemical, tectonic, etc. This paper looks at the influence of the tectonic factor specifically, which actively manifests within the Pervomayskyi and Hannivskyi deposits as fractures, breccias, mylonite of ores and rocks. During the surveys, there were designated tectonically altered kinds of ores and rocks within the both deposits, which take effects on seismic stability of pit walls of the both quarries, and also we put areas with various tectonic intensities on schematic maps. For this purpose, we used geological methods of study (selection of samples, mapping), mineralogical (determining quantitative proportions of minerals, texture, structure of ores and rocks). The study provides the data of mineralogical estimates of tectonically altered types of ores and rocks of productive layers of the Pervomaiskyi and Hannivskyi deposits of the Kryvyi Rih basin. We charted maps with areas of various manifestations of tectonic changes within productive layers of the both deposits.

The article clarifies the peculiarities of the development of vegetation that is formed on the rock dumps of the Southern Mining and Processing Plant or their rock components (lithoecotopes), that is, only lithophilic vegetation. The problem of researching lithophilic plant communities from the point of view of forecasting their natural development and optimization is relevant not only for Kryvbas, but also for all industrial areas of open mining, in which significant masses of hard overburden rocks are brought to the surface of the earth. We have defined various lithoecotopes and described plant groups of varying complexity on plateau peaks, terraces and slopes depending on the specifics of their constituent rocks and typological features. Plant lithophilic groups of dumps of the Southern Mining and Processing Plant in accordance with the state of lithoecotopes, including all typological characteristics and geochemical nature of rocks, are marked by significant analytical (floristic and ecomorphic composition, occur- rence, stratification, physiognomy, abundance, coverage) and synthetic (similarity, constancy) differences signs A detailed study of thecondition of plants and their groups in lithoecotopes made it possible to make sure that their distribution and development have clearly defined substrate and relief-exposure dependencies, which can be used in phytotic and phytocenotic improvement of these man-made ecotopes. The natural overgrowth of all dumps has a mixed shrub-tree forest and grassy character in accordance with the typological characteristics and composition of the rocks. It was found that the change of plant communities on the lithoecotopes left without hu- man influence is endoexogenous in nature, because the ecesis external pressure is imposed on intracenotic processes. As a result of such integration, both fluctuations and successions naturally occur against the background of one or another substrate. The occurrence of species, the species and petrophytic capacity of plant communities, and their petrophytic indices in the lithoecotopes of the dumps have discrepancies depending on the specifics of the conditions. In general, the taxonomic composition of the plant communities of the dumps of the Pidennoy GZK of Kryvbas is determined by 218 species belonging to 54 families, 84 species of which are petrophytes.

For a long time, the tourism industry was considered one of the economy’s lead- ing and most progressive sectors, characterized by an advanced scale of development. The situation was changed fundamentally by the COVID-19 pandemic, which caused significant losses at the global level, not only for tourism but also for all sectors of the economy and society. In this regard, the provision of this article identifies the nature of the impact of the COVID-19 pandemic on tourism in a particular country in the European region using cluster analysis. In the first stage of this work, a detailed literature review on the existence of such a connection was carried out with the help of bibliometric analysis. The authors used the results published in Scopus and Web of Science databases for the keywords «tourism», and «Covid-19» and analyzed the growth dynamics in their number and citations, belonging to the research area and the spread of geography. Building a bibliometric map of keywords based on their joint placement in the VOSviewer software complex deepened findings. It made it possible to form 10 clusters, each of which covers scientific works on various forms of the impact of the COVID-19 pandemic on tourism (for example, behavioral, marketing, economic, environmental, psychological aspects, etc.). In the second stage, an analytical review was conducted, which showed a significant drop in the absolute and apparent contribution of travel and tourism to GDP worldwide in 2020 and 2021 worsened with the pandemic level, and an increase in the dynamics of key indicators of the tourism industry in the world and across all UNWTO regions (especially Asia & Pacific). In the last step, a hierarchical agglomerative cluster analysis (with Ward’s method) was carried out for the countries of the European region (45 countries) based on indicators of the number of COVID-19 cases in the country (cumulative and new), vaccination of the population, the presence of restrictions on tourism, international tourist arrivals, and receipts, collection of tourism in exports. All indicators for analyzing the collected state are provided as of July 30, 2022, using the Stata SE 12 software complex. The construction of a dendrogram and the use of Calins- ki-Harabasz and Duda-Hart stopping rules made it possible to decide on the presence of 3 clusters that meet the conditions of this study and are characterized by different levels of adaptability to post-pandemic functioning and recovery direction.
长期以来，旅游业被认为是经济的主导和最先进的部门之一，具有先进的发展规模。2019冠状病毒病大流行从根本上改变了这一局面，不仅在全球范围内对旅游业造成了重大损失，而且对经济和社会的所有部门造成了重大损失。在这方面，本文的规定使用聚类分析确定了COVID-19大流行对欧洲地区特定国家旅游业影响的性质。在本工作的第一阶段，借助文献计量学分析对这种联系的存在进行了详细的文献综述。作者利用Scopus和Web of Science数据库中发表的关键词“旅游”和“Covid-19”的结果，分析了它们在研究领域的数量和引用的增长动态，以及地理传播。根据关键词在VOSviewer软件综合体中的联合位置，构建了一个关键词的文献计量图，加深了研究结果。这使得形成10个集群成为可能，每个集群涵盖有关COVID-19大流行对旅游业的各种形式影响的科学著作(例如，行为、营销、经济、环境、心理等方面)。在第二阶段，进行了一项分析审查，结果显示，2020年和2021年全球旅行和旅游业对国内生产总值的绝对和表观贡献大幅下降，随着大流行的程度而恶化，世界和世界旅游组织所有区域(特别是亚太地区)旅游业关键指标的动态有所增加。最后一步，根据欧洲地区国家(45个国家)的COVID-19病例数(累积和新发病例)、人口疫苗接种、旅游限制的存在、国际游客入境人数和出口旅游收入等指标，对欧洲地区国家(45个国家)进行了分层聚集聚类分析(使用Ward方法)。所有用于分析收集状态的指标都是截至2022年7月30日，使用Stata SE 12软件综合体提供的。树形图的构建和Calins- ki-Harabasz和Duda-Hart停止规则的使用使得有可能确定满足本研究条件的3个集群的存在，并且具有对大流行后功能和恢复方向的不同程度的适应性。

A set of geological expeditions and routes carried out by M. Y. Lebedev through- out his life was determined for the first time. The specified complex in the context of the set research purpose is analyzed. The purpose of the study is to identify and consider the main geological routes of expeditionary practice of the outstanding geologist M. Y. Lebedev and to generalize practically and theoretically the consequences of their implementation and its organizational activities in the field of geology. The study is based on a combination of theoretical provisions of geological research and the principles of application of the evidence base of historical and natural research. The main geological expeditions, in which M. Y. Lebedev took part, are studied and analyzed, their results are considered and generalized, and the organizational achievements of the scientist are clarified. It was found that the expeditionary practice gave Lebedev the opportunity to accumulate a complex of various geological materials, most of which were innovative. Each of these complexes became the basis for obtaining new theoretical results. The development and application of paleontological methods by M.Y. Lebedev were of particular importance. The method of stratigraphic paleontology developed by him allowed substantiating the new methodology of research of coal deposits of the Donetsk basin. The significance of Lebedev’s activity in the development of Azerbaijani oil production, in particular, the determination of the oil potential the Caspian Seabed near Baku, is pointed out. The cartographic activity of the scientist is described. The influence of M. Y. Lebedev on the formation of the geological service and higher geological education in Ukraine is estimated. The results of the study testified to the diversity of M.Y. Lebedev’s ex- peditionary practice and its role in his formation as a geologist of the European level; its significance in the development of theoretical and practical components of M.Y. Lebedev’s activity was determined, his formation as an organizer of geological research and higher geological education.

In the world, the living conditions and health of the population have a certain impact on demographic processes. High population growth rates cause demographic problems. As a positive solution to these problems, a number of international organizations, including the United Nations Population Fund, have set the main task of «improving the lifestyle of the population and ensuring sustainable development» (https://www.unfpa.org/world-population-trends). These tasks include studies aimed at identifying and evaluating the features of the development of demographic processes in densely populated areas, the factors influencing them, and developing a forecast. In the world, priority is given to research in this direction, especially to determine the territorial features of population regeneration, improve public health and life expectancy, study the impact of economic and social development of regions on demographic processes. It is also important to determine the unique geodemographic situation due to the influence of natural and economic, socio-geographical and other factors on the population of the regions, factors influencing the development of demographic processes and their territorial characteristics, to improve the scientific basis of regional demographic policy and directions of development, and develop special programs . This article highlights the territorial features of the development of demographic process- es in the regions of the Fergana Valley in 1991-2020, developed forecast parameters up to 2040, and presented important conclusions.

The article deals with the application of qualimetric methods for assessing recreational and tourist potential on the example of an ecotourism cluster developed for natural and geographical and socio-economic conditions and resources of the Ukrainian Black Sea region. The properties of recreational and tourist potential can have different nature, different definitions, and be qualitative-descriptive, verbal, or quantitative (numerical). In qualimetric developments, properties should be comparable in the form of representation and magnitude of evaluation scales. The aim of the study is to develop a methodology for qualimetric assessment of recreational clusters. The theoretical and methodological basis is the fundamental principles and developments of recreational geography, tourism studies and qualimetry, as well as the author’s own developments. In the process of writing, general geographical methods were used, such as descriptive, comparative geographical, and qualimetric assessment methods. Characteristics and properties presented in verbal form can be shown as structural combinations and compounds of simpler indicators. Factors that form the recreational and tourist potential have different weights (significance), which requires an appropriate assessment. The overall assessment of recreational and tourist potential is a weighted average value of all its components, taking into account their weight. The available absolute natural indicators of conditions and resources of recreational and tourist potential are also transformed into qualimetric estimates. The general methodological scheme for assessing recreational clusters, specified according to the conditions and resources of ecotourism of the Black Sea region is represented by seven stages – from structuring a recreational cluster according to its components and levels of hierarchical organization, calculating indicators of the weight of properties and calculating criteria for prop- erties that form the corresponding quality, calculating qualimetric estimates for all primary units of recreational and tourist potential; a meaningful interpretation of the assessment of the recreational and tourist potential of a recreational cluster based on the criteria of properties and scales of the corresponding features and characteristics, as well as indicators of the weight of properties in the formation of recreational and tourist potential. The developed scheme should be considered as a methodological approach for the practical application of qualimetric assessments of recreational and tourist potential in recreational geography and tourism studies.
