The most promising position is characteristic of the Aktash group ore occurrences (Aktam-I, Aktam-II, and Yuzhnoe).Within the studied Mingbulak area of Karzhantau, the most widely distributed are mineral occurrences of iron ore, lead and zinc, gold, and copper, and less developed boron-bearing, tungsten, and fluorite ones. Most of the mineral occurrences in the area formed as a result of magmatic-hydrothermal activity and are confined to fault zones characterized by long duration and complexity of the formation. The mineralization is usually localized in the crush zones and feathering fractures of the faults. The skarn type includes ore occurrences of iron, a metal that is currently strongly deficient for mining enterprises in the Tashkent region.","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":"22 S3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91515436","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}

Prospects for the natural uranium world market 世界天然铀市场展望

Based on this forecast, an assessment is made of capabilities of the uranium world mineral base to meet the NPPs needs in the nuclear fuel. It is demonstrated that only the restoration of production at temporary closed down mining enterprises, the growth of output at existing mines, and using secondary sources of uranium guarantee a sufficient amount of the raw materials to meet the demand for uranium in the next decade. Moreover, the shortage of raw materials for nuclear fuel in the near future may again be replaced by its excess. However, by the end of the current or early next decade, due to the depletion of the resource base of some operating mines, including Four Mile and Cigar Lake in Canada, the capacities of mining enterprises will be insufficient to meet the fuel needs of NPPs. A shortage of uranium may appear again, that will grow rapidly in the future. This will mean a new round of growth in prices for natural uranium, which, in turn, will stimulate an increase in uranium production throughout the world and will expand the prospects for the implementation of projects for the development of new uranium deposits in Russia, primarily Argunskoe and Zherlovoe in the Streltsovskoe uranium ore region","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":"7 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88254896","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}

Several gold placer clusters are situated in the region of the Selennyakh River in the middle course of the Indigirka River. They are mainly located along the left bank of the Selennyakh River, in its upper reaches. The right banks of the Selennyakh River, especially in its middle course, remain poorly studied. However, the presence of halos of panned gold concentrates with no obvious relation to probable primary sources of gold, revealed in the 1970s-80s, is a reason for this area to be studied as a gold-bearing one. The article presents results of the 2020-2021 panned heavy mineral concentrate sampling within the Vetvistyi site in the middle reaches of the Selennyakh River, provides a characteristic of the alluvial gold typomorphism, and gives a description of the Neogene deposits drained by the Vetvistyi Stream. The belonging of the Neogene deposits to the Uyandina Formation that fills the Momo-Selennyakh depression has been confirmed. Potentially commercial gold-bearing potential of the Vetvistyi Stream and its tributaries has been substantiated, and gold particles (signs) have been revealed in the Neogene deposits of the Uyandina Formation","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75004089","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 material published below is based on the article “The theory of magmatic ore formation in works by M. N. Godlevsky and its modern aspects” from the anniversary edition and contains minor editorial changes. The article considers the principal theoretical provisions of the magmatic genesis of the Norilsk platinum-copper-nickel deposits, that were developed by M. N. Godlevsky in his works. Particular attention is paid to his still unpublished doctoral dissertation that covers all aspects of the genesis of the unique Norilsk ores: from the formation conditions of the ore-bearing magmas in the northwest Siberian Platform and their crystallization in the upper zones of the earth's crust, to the formation of disseminated and veined ores of the Norilsk 1 and Zub-Marksheiderskoe deposits.
