The expediency of creating traps for macro- and microplastics, the long-term continuous use of which can open new methodological approaches to regular observations of these pollutants, is substantiated. Such field observations combined with the recording of hydrometeorological data (winds, currents, and dynamics of wave activity) will allow to determine the intensity of the introduction of plastic material from certain geographical locations and to investigate probable sources of input depending on the characteristics of its composition.","PeriodicalId":33769,"journal":{"name":"Geologiia i poleznye iskopaemye mirovogo okeana","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67115590","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 leading place in the geological structure of the Osnytsky block is occupied by the rock association, which includes a number of plutonic formations from gabbro to leucocratic granites (gabbro-diorite-granodiorite-granite association), formed in the Paleoproterozoic — 1,98—1,95 Ga. The results of lead-lead isotope dating of titanites from diorites, opened by the RPZ-5 quarry, located in the northwestern vicinity of the village Tomashhorod. Diorites were formed in the second phase, after gabroids, before the beginning of the formation of granitoids. The age of 1975 ± 9,1 Ma was obtained for them. The age calculated based on previously published data is 1973 ± 8,3 Ma, which is in good agreement with the U-Pb isotopic age of the zircons of these diorites 1974 ± 1,2 Ma. It was found that to determine the isotopic age of titanites with a high content of ordinary lead, it is enough to use only the isotopic composition of lead, calculating the age in the coordinates of the graph 207Pb/204Pb — 206Pb/204Pb, by the tangent of the angle of inclination of the regression line.","PeriodicalId":33769,"journal":{"name":"Geologiia i poleznye iskopaemye mirovogo okeana","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67115640","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 sites are currently partially or fully located in the transitional part of the Black Sea Geoecosystem (BSG) space and associated geoecological subsystems of estuaries, where modern natural aerial, aquatic and geological environmental subsystems interface with each other. The article presents the results of research, characterization and typification of archaeological sites of the cultural heritage of ancient and medieval times, which are located in the space of geoecosystems that were formed in this region. Among them are the underwater archaeological sites dis- covered in the space of ancient coastal and littoral paleogeoecosystems of the Bug Estuary, their connection with the most significant archaeological sites that were once formed as part of geoecosystems of the land. A preliminary reconstruction of the borders of the Bug Estuary in ancient and medieval times is made; there is demonstrated the resource archaeological potential of GESNBSC spaces and the adjacent zone of the Black Sea shelf with estuaries, including the ancient and medieval archaeo- logical sites of cultural heritage, which were created and for some time belonged to the spaces of cer- tain paleo-GESNBSC, but are now located in the space of modern geoecosystem of the Bug Estuary. The article gives a brief description of the already known archaeological, partially submerged sites of ancient and medieval cultural heritage, some other interesting underwater archaeological artifacts, and shows the feasibility of expanding their study with reference to bathymetric and geomorphological features of the boundaries between modern natural BSG environmental subsystems. Such knowledge is important both for solving the issues related to a more profound understanding of the causes and consequences of changes in the paleogeoecological and modern geoecological conditions of the shelf of Azov-Black Sea basin and GESNBSC, predicting their dynamics and directions of development, and for historical and archaeological reconstructions, in particular, to identify new cultural heritage sites. The results of geoarchaeological (that is, a complex of geoecological and archaeological) studies published in the article are important not only for understanding the formation and functioning of transitional geoecosystems with their resources, which include archaeological artifacts as anthropogenic components, but also for the development of public culture, historical memory population and expansion of its historical consciousness.

The Dniester Estuary should be considered as a separate and integral geoecosystem, which is composed of interdependent subsystems. Today, anthropogenic activity has a great influence on the state of the estuary, especially the role of the military factor is growing, which is explained by hostilities and destruction in the region where the reservoir is located. In order to assess changes and ensure effective use of reservoir resources in the future, a comprehensive analysis of the pre-war state of the Dniester Estuary is absolutely necessary. The article summarizes the existing information about the bottom sediments of the Dniester Estuary and the unknown results of the expedition research of the reservoir, which were carried out by the authors in 2020-2021. 35 samples of the rocks of the shore and the bottom of the reservoir, as well as 25 samples of water from the bottom layer, were taken. A primary lithological description, an analysis of the granulometric composition of sands, and the content of heavy metals (Pb, Cr, Cu, Cd, Zn) were carried out for samples of bottom and coastal sediments. Maps of the distribution of some of them in the bottom sediments of the reservoir were built, as well as a comparison of the content of these metals with the content in the bottom sediments of adjacent territories, adjacent soils, in the bottom sediments of other estuaries of the northwestern Black Sea region, as well as with existing regulatory characteristics. Elevated concentrations of Pb were established. In the article, the authors present the results of their own research into the regularities of the distribution of pH parameters, redox potential, salinity, and mineralization of water, and for some samples, the powers of the ambient equivalent dose of gamma radiation were determined. A map of the distribution of mineralization values of the southwestern part of the reservoir was constructed. Features of dependence of parameters of mineralization and salinity on pH values were established. The authors identified the main climatic and geomorphological factors affecting and controlling the geoecosystem of the estuary. The article is illustrated with the author's photographs.","PeriodicalId":33769,"journal":{"name":"Geologiia i poleznye iskopaemye mirovogo okeana","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67114997","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}

Each of them is not without its drawbacks. The results obtained allowed us to assume that the determination of the mantle anomaly of the gravitational field can be eliminated their significant part and serve as a unified criterion for identifying the zones of modern activation. For this, it is necessary to improve the methodology for calculating the effect of the earth’s crust, supplementing it with taking into account the degree of catagenesis of part of the rocks of the sedimentary layer, the effect of increased concentrations of ore minerals in the depths of regional magnetic anomalies, etc. Thus, a more accurate calculation of the effect along the DSS profiles can be achieved. In addition, it is necessary to ensure the determination of the gravitational effect of the crust in the area between the profiles. Kriging technology was used to solve this problem. It allows you to calculate the predicted values of the parameter using those known in other points and to estimate the error of the result. In our case, the usual kriging option was sufficient. To determine the errors, instead of the commonly used variograms, a comparison of data on one of the DSS profiles with those calculated by kriging from information on adjacent profiles was used. The resulting error turned out to be quite understandable, taking into account the errors of the initial data, and acceptable for using the results for mapping the mantle gravity anomaly, and, consequently, the zones of modern activation of Ukraine. The constructed map demonstrates some difference in the location of the anomaly (and, accordingly, the recent activization — RA zones) from the previously established one. In particular, the anomaly is absent in the Desnyanskiy basin of the Dnieper-Donetsk depression. Actually, the gravitational mantle anomaly was absent there before, the spread of the RA zone into the basin was indicated by other criteria of low reliability. It is possible to record the presence of an anomaly in the territory between the Azov and Donbas regions, where it was not previously diagnosed. This result still needs to be supported by additional data. First of all, due to the observed significant discrepancies between different variants of velocity sections along the DSS profiles.","PeriodicalId":33769,"journal":{"name":"Geologiia i poleznye iskopaemye mirovogo okeana","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67115086","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}
