In addition, the properties and amount of waters in the hydrosphere in the supercritical state below the Conrad boundary are practically not investigated. Hydrogeochemical regularities are used in mapping, zoning of the territory, as well as for the interpretation of the actual material, and division of the cross-section in the drainage basins. For this purpose, concepts of hydrodynamic and hydrogeochemical floors, hydrogeochemical zones, hydrogeological and hydrogeochemical aquifer complexes and horizons are used. Each hydrogeological area is distinguished by its vertical hydrogeochemical zonation, which synthesizes the most essential features of the evolution of this structure during a particular period of history. As a result, chemical types of waters with zones of a certain thickness, successively replacing each other within adjacent areas or provinces (belts) are formed. The same type of zonation may also characterize a group of structures.","PeriodicalId":30663,"journal":{"name":"Vestnik Permskogo Universiteta Seria Geologia","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710079","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 strata are still poorly studied, and the prospects for their oil and gas potential have not been clarified. The article discusses the definitions of the term “Petroleum system” (“Oil and gas” or “Hydrocarbon”) adopted in Russia and abroad. Based on the study of the collected data, including geochemical and reservoir properties, and basin modeling, three deep-submerged petroleum systems were identified within the territory under consideration. It is shown that the generation of hydrocarbons occurred at a time favorable for the formation of deposits. In the deep sediments of the sedimentary cover, the most important conditions for the formation of oil and gas fields within the framework of the concept of petroleum systems are fulfilled. The presence of source rocks, reservoirs, seals and traps, the realization of generation, migration and accumulation of hydrocarbons, as well as the optimal ratio of the time of manifestation of these processes, and the area of formation of deposits were analyzed.","PeriodicalId":30663,"journal":{"name":"Vestnik Permskogo Universiteta Seria Geologia","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135710922","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}

On the example of the Popovskiy salt dome location, the results of detailed studies and analysis of data on the geological structure of sedimentary strata and their morphology are presented. The reconstruction of the evolution of salt structures, the uplifts and depressions was carried out. The main factors and mechanisms, which controlled the development of a modern tectonic structure of this territory, were determined. Significant role in formation of the modern tectonic features of the upper part of the sedimentary cover played the accumulation in the Kungurian age of the Permian the ductile salt rocks, which, at the Late Paleozoic - Early Mesozoic subsequent stages of the territory evolution, determined the increased tectonic mobility of salt and supra-salt deposits, and the formation of high-amplitude uplifts and basins. Differences in tectonogenesis of the upper part of the sedimentary cover, comprising the ductile salt-bearing strata and the underlying rigid rocks, led to the division of the sedimentary cover of the Solikamskaya depression of the Cis-Ural trough into two tectonic stages. The lower level includes uplifts representing the draping structures of the Fransian-Tournaisian reef massifs and brachianticline folds of longitudinal compression, and the upper level comptises the structures formed as a result of the halokinesis of plastic rocks.","PeriodicalId":30663,"journal":{"name":"Vestnik Permskogo Universiteta Seria Geologia","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135709564","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 products of kimberlite rocks alteration have been studied, the scheme of initial minerals transformation has been constructed, typomorphic features of final weathering products have been revealed, the profile of kimberlite rocks’ weathering crust of Nakyn field has been established. It was shown that saponite in Yakutian kimberlite pipes has a hydrothermal origin that make it possible to use it during prospecting of kimberlite bodies under certain conditions. Complex comparative investigation of ancient weathering crusts of rocks of various chemical and mineralogical composition allowed tracing specific features of their hypergene alteration and typomorphic indications of eluvial products that is very important for solving a number of applied tasks. It is possible to differentiate at the structural level the same varieties of primary minerals in redeposited weathering products of various rocks, as well as identify secondary stratified silicates, differing in the last case either by character of octahedral positions’ occupation in their structure, either by the way of mutual superposition of individual silicate layers or by their polytypic character. That is why redeposited in ancient sedimentary thick layers products of various types of weathering crusts preserve structural and chrystallochemical features in relation to the minerals of eluvial strata, allowing tracing the ways of terrigenous material transport into sedimentation basins (including diamondiferous material","PeriodicalId":30663,"journal":{"name":"Vestnik Permskogo Universiteta Seria Geologia","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135709561","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}
