This time period was chosen, in particular, due to the need to find the prerequisites for the strong shallowing of lake complexes and the depletion of groundwater in the Polish region in 2019, which caused significant social and scientific resonance. The source data for the statistical part of the work were archival information from 17 weather stations in the specified region for this period. The main results of the study: 1) the dynamics of the average monthly precipitation amounts for each meteorological station were calculated and analyzed (Lutsk, Svityaz, Manevychi, Kovel, Liubeshiv, Volodymyr, Rivne, Dubno, Sarny, Brody, Rava-Ruska, Kamianka-Buzka, Pinsk, Pruzhany, Terespol, Wlodawa, Zamosc), the average amounts of precipitation that fell during the warm season of the year (IV-X months) and the cold season of the year (XI-III months), average annual precipitation amounts and precipitation amounts for the entire period, which was investigated (2010-2018). All calculated indicators were compared with the data of the climatic norm of 1961-1990). The annual number of days with precipitation, the warm and cold periods of the year, and the average values of this indicator were also determined. Based on the results of the statistical analysis, charts, cartograms, and several diagrams were developed that visually represent the peculiarities of the dynamics of atmospheric precipitation in the studied region during the analyzed period (2010-2018). 2) on the basis of the calculated indicators, maps of the geographical distribution of precipitation amounts on the territory of the cross-border region Poland-Belarus-Ukraine during the studied period (annual amounts, cold and warm season amounts) were constructed. When comparing them with maps of the period of the 20th century. Changes in the geography of distribution and trends of modern growth of precipitation amounts in the study region were revealed. After the analysis, a number of conclusions and generalizations were made: 1. During the period 2010-2018 in the territory of the cross-border region Poland-Belarus- Ukraine, the average annual amounts of precipitation increased by 20-45 mm compared to the climatic standard, while the average annual number of days with precipitation decreased by 25-30%. 2. Annual amounts of precipitation exceeded 600 mm at almost all (16 out of 17) meteorological stations whose data were analyzed. 3. The distribution of days with atmospheric precipitation during the seasons of the year has changed. The ratio between the amounts of precipitation that fell in the warm and cold periods of the year changed from 75/25 to 60/40 on average. In general, in the studied region, there are trends towards a slight increase in annual precipitation amounts, a redistribution of precipitation amounts in liquid and solid state in favor","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"167 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76933352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is to characterize the dynamics of demographic burden on the employable population of Ukraine for the period 1989-2021, to identify patterns of influence of the demographic crisis and aging processes of the population on the growth of the demographic burden indicator. Based on the processing of statistical information of the State Statistics Service of Ukraine, census data in 1989 and 2001, an analysis of the demograph- ic burden in Ukraine in general and in some of its regions in particular, revealed peak years of demographic burden on the employable population and indicated the causes of such a phenomenon. The analysis of the dynamics of the main demographic indicators of the population of Ukraine made it possible to establish that the long period of low birth rate over the past three decades, the insignificant increase in mortality among the elderly population against the background of a sharp increase in mortality in working age, as well as the impact of migration processes have left a deep imprint on the level of demographic burden. A comparative analysis of the total demographic burden factors in Ukraine and the EU countries was carried out. It was found that in all EU countries, the structure of the overall load is dominated by the burden of the elderly (over the age of 65 years), which emphasizes the deepening of the aging process- es of the population. Analysis of the age structure of the population of the countries of this group confirms that in the future the share of people of disabled age will only grow, and accordingly, the indicator of demographic burden will increase, which threatens to increase the so-called «social abstinence». The obtained results allow us to conclude that there are signs of «demographic degradation» and «demographic reurbanization» of the employable population in Ukraine. And in the future, the age structure of the population in Ukraine will move towards aging: the number of elderly people will increase, and the number of people of employable population will decrease. This, in turn, will lead to a significant increase in the demographic burden on the employable population. To solve this problem, a set of effective and thoughtful measures of demographic and social policy is needed, which will be aimed at effective and rational regulation of migration flows, creation of new jobs, increase of wages and productivity of labor, improvement of the taxation system, etc. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"10 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78478125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These wastes contain a large number of elements that are harmful to the environment. In this case, of phosphate wastes from Djebel Onk in the form of sludge that are the subject of our work, several trace elements have been recorded in limited levels. Indeed, elements such as lead and chromium have levels that exceed 60 and 300 ppm respectively. They far exceed the requirements of the mineral industry. The legislation, the severity of which varies from country to country, increasingly requires rigorous management and monitoring of these wastes in order to guarantee the protection of the environment from these toxic substances contained in the wastes. This work focuses on the management of phosphate wastes from Djebel Onk in liquid or sludge form. Current practices on their evacuation from neighbouring valleys to the operating site may harm the local environment. Moreover, the flow of this sludge which is increasingly thickened becomes more difficult. In this context, for environmental considerations and in order to define a concept linked to sustainable development, this study advocates a new approach in the recovery of phosphate wastes. It is based on the intrinsic properties of the present minerals determined by qualitative and quantitative analysis developed by different characterization techniques (XRD, XRF, IR, etc.). This makes it possible to define the chemical and mineralogical composition of liq- uid phosphate wastes which are rich in calcite (44.45 % in CaO) to those of phosphate elements (21 % in P2O5) and gangue minerals such as dolomite (7, 6 % in MgO), and quartz (5.8 % in SiO2). The microscopic observations carried out on these wastes showed the presence of the main minerals identified by XRD: fluorapatite, hydroxylapatite, carbonate, dolomite, calcite and quartz.

The role of the relevance, timeliness of the information provided on a particular tourist product is growing. Ecological tourism has features, as the objects of tourist activity are little-visited natural-territorial complexes, characterized by a certain spatial distribution in the territory. It requires the use of geographic information technologies, remote sensing systems, global positioning in order to organize tourism facilities, which determines the relevance of this study. The purpose of the study is to substantiate the significance of creating innovative ecotourism products based on the use of modeling systems and modern technologies, including geoinformation, determining the value of ecotourism and the study of competitive advantages for tourism enterprises which enable them to make a profit from the provision of ecotourism services.

By using a number of paleoprofiles constructed based on the seismogeological profile running in a southwest-northeast direc- tion, as well as morphological specifics of the local elevations developed within both the Absheron Ridge and the Turkmen shelf, we plotted and analyzed isomorphic maps reflecting the properties of distribution of the compressive stresses. Based on the paleoanalysis, we determined that the isometric Janub elevation, neither morphologically nor genetically, can be included into the same anticline zone as the local elevations under consideration. Studies suggest that they have developed under different tectonic regimes and the Janub structure belongs to a group of folds formed under another tectonic regime, i.e. new predicted anticline zone. The Janub-2 elevation, located southeast of the Janub fold, can be attributed to the predicted new anticlinal zone. In order to trace the continuation of this anticline zone in the southeast direction and identify potentially promising new buried elevations, it is advisable to carry out new series of transverse deep seismic profiling works in the southwest-northeast direction. The analysis revealed that the oil and gas potential, folding and evolution of mud volcanism in the area under study are associated with geodynamic processes. The impact of compressive stresses, as a geodynamic factor, on folding and faulting of the sedimentary mantle, mud volcanism and oil and gas potential is a relevant topic to study.

To calculate the amount of heat generated during oxidation, the dependences of the oxygen absorption rate on the temperature and moisture of the ore were established. It was found that with an increase in temperature above 50-80oC, absorption of oxygen slows down with time faster than at low (2.5-50oC) temperatures. If with an increase in temperature from 2.5 to 45-50oC the amount of absorbed oxygen increases by 7.5-12 times, then at a temperature from 45-50oC to 80oC it increases only by 3.6-3.7 times, which is explained by a decrease in moisture of the ore with an increase in temperature, due to evaporation. The time dependence of absorption rate of the oxygen for sulphide ores of sulphide-polymetallic deposits of Azerbaijan has a clearly pronounced break, which indicates a change in the oxidation mechanism. The oxidizing activity of sulphide ores of sulphide-polymetallic deposits of the Balakan ore field of Azerbaijan at low temperatures (2.5-800C) was studied. Determination of the oxidative activity of the main industrial types of sulphide ores of sulphide-polymetallic deposits in Azerbaijan makes it possible to classify ore reserves according to the degree of tendency to spontaneous combustion, which will allow a scientifically sound approach to planning the sequence of their development and designing mines. In addition, the article presents the results of experimental studies to determine the oxidizing activity of the sulfide ores of the Katsdag, Filizchay and Katekh deposits, carried out in laboratory conditions by the method of Institute of Mining named after A.A. Skochinsky. An indicator of oxidative activity is the oxygen absorption rate constant and labeled by the letter U (ml/g hour). The results of laboratory studies show that the oxidation of the ore leads to an increase in temperature and ignition and depends on a large number of factors such as mineralogical composition, chemical activity, humidity, temperature, fragmentation, etc. The dependence of the total amount of oxygen absorbed by sulphide ores on time at various temperatures is obtained. It has been estab- lished that with increasing temperature, the rate of oxygen absorption by sulphide ores increases. The values of the temperature coefficient (Kt < 2.0) in the temperature range of 2.5-800C show that the rate of the oxidation of sulfide ore is controlled by oxygen diffusion, and not by the rate of the chemical reaction. With equal fragmentation and equal distribution of chemical elements in ore samples, the oxidation rate is directly proportional to the outer surface of the sulphide ore. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"48 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82035812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fields that are being operated for a long time, the prospects for industrial hydrocarbon accumulation can be associated with secondary gas traps of non-traditional type, in particular, technogenic ones, which are formed in low-pore collectors. The authors carried out a detailed analysis of the well-known gas and gas condensate fields of Ukraine. The Rudkivske gas field of the Western oil-and-gas bearing region was chosen. The purpose of the study is to clarify the geological conditions for the formation of technogenic collectors and attracting additional volumes of gas under the action of a geomechanical factor while operating the Rudkivske gas field. The quoted results of the research prove the effect of gas extraction from the deposits of the J-h horizon on the formation of secondary technogenic collectors by attracting additional volumes of gas from the of ND-4, ND-5, ND-7 productive horizons and the formation of a new (ND-10) one, which subsequently connected to the gas production. Attracting additional gas volumes is due to the gas influx from newly made technogenic collectors, which were formed under the action of a geomechanical factor in the process of long-term development of the field. The formation of technogenic collectors occurred due to the compression of the main reservoir of the Jurassic age (J-h), the deformation of the rock strata, and the decomposition of the overlying rocks, the development of the crack propagation, permeability increase and gas recovery rising. The geomechanical factor management opens the prospect of obtaining additional industrial gas influx in the late stages of the development of gas and gas-condensate fields, by predicting the geological conditions for the formation of improved secondary filtration and capacitive properties favorable to form technogenic gas deposits. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75452390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
