In this article, the problem of the philosophical foundations of the geographic theory of geoecotone is considered. As such, the authors propose the traditions of neopla- tonic philosophy, based on the ontological teaching of Empedocles, the modern philosoph- ical teachings of the actor-network theory of B. Latour and object-oriented ontology. The noospheric power of a person is realized in globalization processes through the expansion of various social and economic institutions, primarily the global ones, which cause corresponding changes in the activities of institutions at lower system levels, and those, accord- ingly, already have a direct impact on their environment. The borderline character of the geoecotone is historically enhanced as the anthropogenic impact on the geographic shell as a whole and its individual elements intensifies. Geoecotones are formed as a special type of geosystems, which are complex systems characterized by a contradictory unity of internal heterogeneity and functional connectivity. The action of the anthropogenic factor is so broad that almost any fragment of modern geospace can be classified to geoecotones in the state of bifurcation and uncertainty. The direct result of the development of mankind was the formation of multilevel ecological and economic systems. It has been determined that the spatial formation of such systems is directly related to the geoecotonization of the geographic shell. The authors analyze the approaches to the philosophical substantiation of the study of the culture and socioge- netic functions of the geoecotone. The formation of geoecotones is an objective process leading to the transformation of geographical knowledge itself. The logical-dialectical comparison of the processes of geoecotonization leads to the idea of their isomorphism with the processes of the development of geographical science, characterized by the universalization and complication of the category-conceptual apparatus.

Based on the geological and commercial material collected and systematized by the offshore fields of Azerbaijan, the article discusses the reasons for the varying degrees of use of their reserves. For this purpose, the identification of deposits was carried out accord- ing to the natural regime, as a complex factor affecting oil recovery. Oil recovery models have been obtained for offshore reservoirs, draining mainly in two types of mechanisms: mixed and solution gas drives. Based on these regression equations and geological-economical analysis, a comparative analysis of the factors influencing oil recovery was carried out. Study of the different nature of the implementation of reserves of deposits characterized by different natural mechanisms so as to determine the degree to which the geological and technological parameters at various stages of development influence oil recovery. Objects: Offshore deposits of the Republic, characterized mainly by the solution gas and mixed drives. Application of the methods of mathematical statistics (Student’s and Fisher’s criteria) for the comparative analysis of the parameters of the mined deposits, confined to different natural conditions, allowing the revelation of the degree to which they are different and various patterns of the use of the reserves. In order to determine the influence of various factors on oil recovery, we used the method of correlation-regression analysis. It was found that a wide range of changes in oil recovery factors is associated with the internal structure of the deposits, with varying degrees of activity of the energy of the reservoirs and the fluids saturating them. It is known that each of the geological and technolog- ical parameters to one degree or another affects oil recovery, this influence is complex and subject to certain changes in the process of reservoir mining. In order to study the influence of parameters on oil recovery, we developed matrices of averaged values of a number of parameters of offshore deposits draining by mixed and solution gas drives. Using multivariate correlation-regression analysis and appropriate software, we obtained models for each of the above types of the mechanisms. A comparative analysis of those models, as well as geological and field studies of the parameters included in the obtained regression equations, make it possible to correct the oil production process in a timely manner, and can also be used in designing projects for the additional mining of those objects.

The article presents the results of petrographic research of building stone that was used for the construction of a cromlech, sanctuary, and the ceiling of the Eneolithic burials No. 20 – 22 from the kurgan No. 29 near Shakhtar village, Nikopol rayon, Dnipropetrovsk oblast. The purpose of this work was to establish a probable place for mining the stone blocks and rubble used in the construction. As a result of petrographic and X-ray fluorescence analysis, it was determined that the studied rocks can be divided into two groups, namely granitoids and limestones. The group of granitoids included tonalites, plagiogran- ites (trondhjemites), altered granite gneiss, and feldspar crystal from pegmatite. All the limestones were represented by spherical lay- ered aggregates, which most likely belong to oncoids – carbonate structures that form as a result of cyanobacteria growth. The studied samples from the materials of the cromlech and the sanctuary of burial No. 22 were represented by plagiogranitoids, pegmatoid granite, and limestones. The first of them served as the main material for the construction of the cromlech. Carbonate aggregates together with the granites were also used as a backfilling when installing wooden pillars of the cult complex associated with the burial. The plates covering the burials No. 20 and 21 were made of tonalites. All the studied granitoids are typical rocks for the area where the excavations took place. In the Middle Dnipro Area, plagiogranitoids are represented by the rocks of the Dnipropetrovskyi, Surskyi, Saksahanskyi, and Inhuletskyi complexes of the Archaean. Plagiogranitoids of the Dnipropetrovskyi complex are the most common in the studied area. They occur here in the middle and upper reaches of the Solona River and along the rivers of Bazavluk and Bazavluchok upstream the Sholokhove Reservoir. The closest to the excavation site are the occurrences of plagiogranitoids, which are exposed on the right bank of the Solona River, opposite the village of Shakhtar. In this area, pegmatoid granites are found in the form of veins that intersect plagiogranitoids. In the area of excavations, carbonate oncoids are found in the Sarmatian limestones of the Neogene. Most often they are found as the uncemented specimens that spilled out of the limestones. Today, such structures occur on both banks of the Kakhovske Reservoir, located south of the village Shakhtar. However, in ancient times there may have been closer outcrops of these rocks, as the Sarmatian limestone occurrences are common in the immediate vicinity of the excavation site, namely between the rivers Bazavluk and Solona, near their confluence, and the middle and upper reaches of the Chortomlyk River. As a result of the research, it is proved that in the valley of the river Solona during the Eneolithic, there began the active extraction of stone raw materials for mound construction, which was continued in later epochs, particularly, in the Scythian time.
本文介绍了对第聂伯罗彼得罗夫斯克州Nikopol rayon Shakhtar村附近的kurgan No. 29号新石器时代墓葬20 - 22号天花板上用于建造墓室、圣所和建筑石材的岩石学研究结果。这项工作的目的是为建筑中使用的石块和碎石建立一个可能的开采地点。通过岩石学和x射线荧光分析，确定所研究的岩石可分为花岗岩类和灰岩两类。这组花岗岩包括渐长岩、斜长岩、蚀变花岗岩片麻岩和伟晶岩中的长石晶体。所有的石灰石都以球形层状聚集体为代表，这些聚集体很可能属于碳酸盐结构，这是蓝藻生长的结果。克罗姆勒奇和22号墓葬圣所的材料样品主要为斜花岗质、伟晶状花岗质和灰岩。其中第一种是建造克罗姆莱的主要材料。在安装与埋葬相关的邪教建筑群的木柱时，碳酸盐聚集体和花岗岩也被用作回填物。20号和21号墓葬的墓板是用调性石制成的。所有被研究的花岗岩类都是发掘地区的典型岩石。在中第聂伯罗地区，斜花岗岩体以太古代的第聂伯罗petrovskyi、Surskyi、Saksahanskyi和Inhuletskyi杂岩为代表。第聂伯罗彼得罗夫斯基杂岩的斜花岗类在研究区内最为常见。它们出现在索洛纳河的中上游，以及绍洛克霍夫水库上游的巴扎夫鲁克河和巴扎夫鲁克河沿岸。离发掘地点最近的是斜花岗岩体的出现，它们暴露在索洛纳河右岸，与Shakhtar村相对。在这一地区，伟晶花岗岩以脉状的形式与斜花岗岩体相交。在发掘区，在新近纪的萨尔马提亚石灰岩中发现了碳酸盐类瘤状体。大多数情况下，它们是从石灰石中溢出的未胶结的标本。今天，这种结构出现在位于Shakhtar村南部的Kakhovske水库的两岸。然而，在古代，这些岩石的露头可能更近，因为萨尔马西亚石灰岩在挖掘地点附近很常见，即Bazavluk河和Solona河之间，靠近它们的汇合处，以及Chortomlyk河的中上游。研究结果证明，在新石器时代的索洛纳河流域，人们开始积极地提取石头原料来建造土堆，这一活动在后来的时代，特别是在斯基泰时代继续进行。

The purpose of the work is to reveal the regularities of the influence of the gaseous phase on the process of filtering carbonated liquid and to characterize the physi-cochemical processes during the implementation of the method of reducing mine methane emissions. The development of minerals can be accompanied by the release of a large amount of methane into the mined-out space. This leads to atmospheric air pollution and consequently to ecological disturbances. This causes methane emissions to the mined-out space and to the surface of the earth cause by the filtration processes of gases and liquids in the rocks. The intensity of fluid filtration through crack and pore systems depends on the content and properties of the fluids and the reservoir properties of the rocks. It is known that methane release to the atmosphere can be observed after mines have been mothballed. This is a problem for many countries around the world where coal and oil and gas fields are being exploited. Investment in methane production and utilization projects is therefore important. Research on fluids filtration processes allow for the development of effective methane recovery methods, and ways to reduce methane emission speed. The result is the reduced air pollution and an improved environmental situation. The paper presents the filtration properties of rocks with different structures and textures. Filtration of carbonated liquid (water-methane) in fractures and pores is considered. It found that an increase in methane concentration in the carbonated liquid leads to a decrease in the phase permeability coefficient for water and an increase for methane. This character of change in phase permeability leads to methane accumulation in crack and pores. The dependence of the average carbonated liquid filtration rate in a rectilinear fracture on the methane concentration and the fracture axis angle of inclination is obtained. The average ascending filtration speed of the carbonated liquid is determined to be greater than the average descending filtration speed. This is due to the effect of the ejection force that acts on the gas bubbles in the liquid. The authors propose a method of blocking methane seepage by physicochemical treatment of the rock mass. The methane blocking effect is achieved by creating a gas-tight zone in areas with a high risk of methane migration to the ground surface. The result is a reduction in methane emissions to the mined-out space and the environment. When the method is realized, the solid product of the polymer solution enters cracks with a disclosure greater than 6 μm or pore channels with an average diameter of 6 μm. At the same time, the water released by the destabi- lization of the polymer solution blocks the methane in small cracks and pores. In pore channels with an average diameter of less than 25 μm, there is a sharp increase in the dynamic viscosity of the polymer solution. This effect is due to an increase in the intermolecular intera

The article examines the geodynamic conditions for the formation and distribu- tion of non-structural traps in the oil and gas regions of Azerbaijan, such as the interfluves of the Kura and Gabirri, Yevlakh-Aghjabadi, Ganja, Lower Kura, the Baku archipelago, Shamakhi-Gobustan and Absheron. For this purpose, the surfaces of the Baikal basement, Mesozoic and Maikop deposits of the region were modeled and analyzed. The modeling revealed a submeridional uplift (positive tectonic element) that began to develop in the Maikop between the Kura and South Caspian basins. This has strongly influenced the folding and especially the formation of non-structural (tectonically sealed, lithologically limited, stratigraphic unconformity-associat- ed) traps in the region. As a result of the analyzes, we clarified the geotectonic characteristics of the formation of non-structural traps (tectonically sealed, lithologically limited, stratigraphic unconformity-associated) and compiled their distribution maps based on them. The analysis of these maps makes it possible to substantiate the features and reasons for the formation and distribution of non-struc- tural traps in the region. Thus, tectonically sealed traps were formed mainly in the oil and gas-bearing areas of the Kura and Gabirri interfluve, the Lower Kura, Shamakhy-Gobustan, Absheron and Baku archipelago, which are not only located in an active geotectonic zone, but likewise, the geological section of these oil and gas-bearing regions (OGBR) significantly differs from the Yevlakh-Aghjabadi and Ganja clay composition (clay rocks), and therefore, high parameters of the development of mud volcanism and clay diapirism are seen in the area. By contrast, in the Yevlakh-Aghjabadi and Ganja oil and gas regions, mainly effusive rocks have developed, which have incompetent properties and resist geotectonic – tangential-horizontal-compressive forces. Formed in this part of the region, thetraps associated with lithological wedging out have been mainly formed by covering the effusive or relief ledges.

The aim of the research was to develop areas for optimization of valley-river landscape-technical systems (LTchS) on the example of the model region – the Right Bank of Ukraine. The research was based on the materials of the long-term field observations which were carried out in the context of the studies of F.M. Milkov about anthropogenic landscapes. The use of expeditionary and stationary research techniques made it possible to receive the required material for the development of the optimization options of valley-river landscape-technical systems. Six options/practices for the optimization of valley-river LTchS on the example of the Right Bank zone of Ukraine are suggested. Option A does not envisage a control regain over landscape-technogenic systems (LTS); it can be used locally. Option B1 is directed towards a partial restoration of the previous func- tions of the system and an episodic/occasional control over a technical block of LTS. Option B2 implies a total change of the economic purpose of LTchS with the aim of recreation. Option B3 consists in making a nature reserve of some landscape technogenic systems,in perspective the range/habitat of unique species of flora and fauna can be saved or restored on these territories. The restoration of a landscape-techno-genic system to the «operation» stage with previous functions is achieved when option C1 is used. Option C2 requires substantial capital investments, as it implies the creation of an absolutely new landscape-engineering system. For this option, projects have been developed to restore sections in the valleys of the Sob River (Gaisyn city, Vinnytsia region) and the Hirskyi Tikych River (Buky town, Cherkasy region). A layout of the optimized valley-river LTchS on the territory of the Right Bank of Ukraine was suggest- ed. The conclusion has been made that the use of one of the suggested options will not help improve the condition of all valley-river landscape-technogenic systems of the model region. Each river valley requires an individual approach in which the combination of all the above-mentioned directions will be used.

The research was based on the materials of the long-term field observations which were carried out in the context of the studies of F.M. Milkov about anthropogenic landscapes. The use of expeditionary and stationary research techniques made it possible to receive the required material for the development of the optimization options of valley-river landscape-technical systems. Six options/practices for the optimization of valley-river LTchS on the example of the Right Bank zone of Ukraine are suggested. Option A does not envisage a control regain over landscape-technogenic systems (LTS); it can be used locally. Option B1 is directed towards a partial restoration of the previous func- tions of the system and an episodic/occasional control over a technical block of LTS. Option B2 implies a total change of the economic purpose of LTchS with the aim of recreation. Option B3 consists in making a nature reserve of some landscape technogenic systems,in perspective the range/habitat of unique species of flora and fauna can be saved or restored on these territories. The restoration of a landscape-techno-genic system to the «operation» stage with previous functions is achieved when option C1 is used. Option C2 requires substantial capital investments, as it implies the creation of an absolutely new landscape-engineering system. For this option, projects have been developed to restore sections in the valleys of the Sob River (Gaisyn city, Vinnytsia region) and the Hirskyi Tikych River (Buky town, Cherkasy region). A layout of the optimized valley-river LTchS on the territory of the Right Bank of Ukraine was suggest- ed. The conclusion has been made that the use of one of the suggested options will not help improve the condition of all valley-river landscape-technogenic systems of the model region. Each river valley requires an individual approach in which the combination of all the above-mentioned directions will be used. The valley-river landscapes optimized with help of the presented scheme will form the image of nature of a present-day European state which will favour the establishment of the concept of well-balanced development. \u0000 \u0000 \u0000","PeriodicalId":42282,"journal":{"name":"Journal of Geology Geography and Geoecology","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2022-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84503741","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}

Currently, society and industry are developing at a rapid pace, and an increas- ingly serious problem of the modern world is environmental pollution, requiring recycling and reuse wastes. Modern technologies in the field of road construction involve the use of polymeric materials obtained from waste recycling. Almost nothing is known about soil contamination by plastic in general and the destruction of roads in particular; probably because of lack of awareness and absence of standard methods for quantifying plastic components in soil. The contemporary data suggest that flow of plastic has already reached a value similar to that found for other contaminants, such as heavy metals. In particular, migration is observed for plastic microparticles, but so far, their effect on groundwater has not been studied. Therefore, additional research is urgently needed to shed more light on the fate and impact of these persistent materials in the terrestrial environment. The purpose of the study was a geoecological analysis of the risks of using polymer waste in construction of roads to the geological environment. To ensure environmental safety in the implementation of technologies for the utilization of polymer waste, it is necessary to take into account their chemical composition, the ability to form hazardous products in increasing temperature, hazard class, physical and chemical properties. We propose criteria for assessing the possibility of recycling polymer waste in road construction, namely for the manufacture of asphalt concrete. According to the pro- posed overall criterion, taking into account not only technical and economic indicators, but also the environmental component, we can recommend the use of HDPE and LDPE, as well as PP for use in road construction. Taking into account the total criterion, we recom- mend using HDPE, LDPE as the most acceptable waste for road construction,, as well as PP. The technological scheme should include the collection, sorting of these plastics, as those that do not contain hazardous chemicals. Temperature conditions for manufacturing asphalt involve heating and converting the components into the liquid phase for uniform mixing of the entire composite. Under those temperature conditions, chemical compounds that are harmful to the environment and humans would not be created. The possibility to substitute part of the bitumen, to obtain asphalt concrete with high performance, increased service life shows the cost-effectiveness of using these groups of polymer waste in the technology of manufacturing asphalt concrete. The lack of regulatory framework and technical standards for working with polymers for paving brings the problem of plastic roads to the legislative level.

This article discusses the stages of crystallization of the Eocene trachybasalt-tra- chyandesitebasalt-phonolith formation of the Talysh zone. Determination of the composi- tion of the primary magma, evolution and melting fraction of the initial melt of the Eocene volcanism of the Talysh zone within Azerbaijan. Eocene volcanism of the trachybasalt-tra-chyandesitebasalt-phonolith formation of the Talysh zone. Petrographic, petrochemical, geochemical studies of rocks, typomorphic features of mineral paragenesis, chemical composition of rocks were carried out by X-ray spectral and X-ray fluorescence analysis. The analyzes of the conducted studies show that the Talysh zone was formed in the Eocene time. Stages of evolution of the original magma and typomorphic features of mineral parageneses have been established. The distributions of microelements in mineral parageneses, which are direct participants in the crystallization processes that took place in intermediate chambers at different depths, have been studied. At present, the question arises of the need to clarify the typomorphic features of igneous complexes, as factors that determine the geodynamic regimes of their formation, and to determine the potential ore content. The petrographic and petrochemical characteristics of the volcanic rocks are given. It was found that if the process of differentiation in the Early-Middle Eocene was more distinct with the initial formation of more magnesian rock varieties (picrite-trachybasalts), and subsequently more ferruginous ones (trachyandesites and trachyandesitebasalts), then such accumulation of iron is not observed in porphyritic trachyandesites. This petrochemical feature is obviously associated with the duration of the break in volcanism, caused by the formation of a thick sedimentary-tuffaceous stratum, accompanied by the initiation and manifestation of an intermediate chamber of medium composition. Volcanism in the Late Eocene was undifferentiated and was not accompanied by the formation of medium differences. The appearance in the late Eocene of leucite phonolites, which represent an alkaline branch, and the absence of transitional varieties indicate the autonomous development of vit- robasalts and leucite phonolites. It is concluded that from the early phases of the manifestation of Eocene volcanism to the later phases, the change in the material composition along the lateral is expressed in the manifestation of more alkaline facies with a significant predominance of K over Na and with a greater correspondence to the differentials of the shoshonite series.

The main purpose of the study is to optimize the functional zoning of the «Hut- sulshchyna» National Nature Park on the basis of a landscape approach. To begin with, a map-scheme of modern functional zoning in the ArcGIS 10.0 software environment was digitized, and analysis and mathematical calculations were performed. On the basis of a pre-concluded landscape map at the level of simple tracts in the scale of 1:25 000, on the key area Brusnyi, according to the method of field landscaping of H.P. Miller’s mountain areas, we have optimized in detail the functional zoning of the park in a key area. Some changes have been made regarding zoning in other areas of the National Park, only less detailed, as the compilation of a landscape map of the local level for the entire territory of NEC «Hutsulshchyna», which is a very long and complex process. In addition to the landscape approach, according to which the boundaries of functional zones must coincide with the boundaries of natural territorial complexes of a certain rank, we tried to take into account the Law of Ukraine «On Nature Reserve Fund of Ukraine» and «Nature Chronicle Program for National Parks of Ukraine». Ideally, the protected area should be in the middle, surrounded wth a zone of regulated recreation, and only then the economic zone. The protected area should not border the economic one. According to the IUCN, the protected area and the regulated recreation zone must occupy at least 75% of protected area, but often in practice these requirements are difficult or even impossible, as each protected area has its own geographical features. Since the park is located in a hilly area, the economic zone should not be allocated on the ridges and upper parts of the slopes, because the effects of anthropogenic impact in the economic zone will be more or less manifested in the protected area, which is at the lower hypsometric level. Analyzing the functional zoning in the key area of Brusnyi, it was found out that in addition to the geographical location of the zones, the areas of the functional zones have also changed significantly. Thus, the protected area was 15.1%, and became 25.1%, regulated recreation – 34.2%-41.9%, stationary recreation area – 0.01%-0%, economic zone – 51.1%-33%. The advantage of the proposed zoning is the complexity, which makes it possible to protect fully and completely and use rationally the natural territorial complexes of the Pokut Carpathians. After all, natural complexes are a system, and it is known that in the system, when one component is destroyed, the whole system is destroyed.

The issues considered in the paper bear a direct relation to the disputable geo- chemical problems of the origin of oil – one of the main sources of modern energy gen- eration. Features of metal distribution in oils have not been studied yet, and natural classifications of oil fields of the Dnipro-Donets depression according to their contents have not been developed before. That stipulates the scientific novelty of the obtained results. Topicality and practical implications of the carried out studies are mainly in the fact the determined features of metal contents in oils and the classifications of deposits developed on their basis will favor the elaboration of a set of predictive criteria for industrial accumulations of hydrocarbons and scientific sub- stantiation of geological-economic, technological, and environmental estimation of their use. The objects of long-term studies include 36 oil fields: Bakhmatske; Prylutske; Krasnozaiarske; Kachalivske; Kremenivske; Karaikozovske; Korobochkynske; Kulychykhinske; Lipovodolynnske; Monastyrishchynske; Matlakhivske; Malosorochynske; Novomykolayivske; Perekopivske; Prokopenkivske; Radchenkovske; Raspashnovske; Sofiyivske; Sukhodolivske; Solontsivske; Solokhivske; Talalayivske; Trostianetske; Turutynske;Kharkovtsivske; Shchurynske; Yuryivske; Yaroshivske; Khukhrianske; Sahaidatske No 1; Sahaidatske No 13; Kybytsivske No 5; Ky- bytsivske No 51; Kybytsivske No 52; Kybytsivske No 56; and Kybytsivske No 1. They are located within the large tectonic structure of Eastern-European platform – Dnipro-Donets depression. The fields form the Dnipro-Donets oil and gas area of Ukraine. The paper is based on the results of studies of not less than 30 oil samples from each of the fields aimed at identification of metal content with the help of X-ray fluorescence analysis using energy-dispersion spectrometer «Sprut» SEF 01. Natural classification of oil fields in terms of content of each of the considered element have been developed basing on the results of cluster analyses implemented in terms of professional software platforms of versions STATISTICA 13.3 and IBM SPSS Statistics 22. The main scientific value of the obtained results is represented by the following: the development of natural classifications of oil fields of the Dnipro-Donets depression accord- ing to the results of cluster analysis of the content of metals, sulfur, and V/Ni ratio and substantiation of 5 new geochemical criteria for the division of fields formed by oils generated mostly by abiogenic or biogenic processes.
