F. I. Wolfson: Scientist,teacher, and patriot

Following a brief biography, the scientific, administrative, and educational activity of F.I. Wolfson is described. Also considered are the principal lines of his research: the study of the structures of ore fields and deposits, the geology of uranium deposits, the theory of hydrothermal ore formation, and the history of the study of ore deposits. The immense contribution made by Wolfson to the development of the mineral resources of the country (uranium, nonferrous metals, etc.) is shown and the continuing relevance of his theoretical and methodological works in the field of geology of ore deposits is emphasized.     

Engineering geology of loess and loess-like deposits: a commentary on the Russian literature

Loess and loess-like deposits were much studied in the Soviet Union, and are currently under investigation in Russia and surrounding countries. There is a vast literature in Russian, which touches on all aspects of loess science and technology. In particular, the studies of the origin of collapsibility are almost totally in Russian, and of course studies on the various regions of Russia and the countries of the Former Soviet Union FSU appear in Russian. This review looks at the literature in Russian and attempts to pick out key contributors, major topics and works and to identify the critical regions and zones of investigation. Because so many regions of the FSU had people living on loess ground, there is a vast literature on engineering geology and ground engineering topics, and this tends to dominate all the literature on loess in Russian. Following Russian practice, the fine-grained deposits under consideration are divided into loess and loess-like deposits. Three main topics are recognised across the whole spectrum of loess research: formation and distribution of loess deposits; stratigraphy, cyclicity and palaeoclimatology; and engineering topics, in particular hydrocollapse and subsidence, and we concentrate on the engineering geology topics. An attempt is made, based on the map of Abelev and Abelev [Abelev, Yu.M., Abelev, M.Yu., 1968. Fundamentals of design and construction on collapsible macroporous soils, 2nd ed. Stroiizdat, Moscow, 431 pp. (in Russian)] of collapsing loess deposits, to define seven loess regions within the geographical limits of the old USSR. The seven regions are those where geotechnical problems might be expected.     

李四光和卡尔宾斯基金质奖章

中国地质学家李四光与当时苏联地学界来往交流紧密,他对地质学的贡献得到了苏联地质学家的高度评价。1958年,苏联科学院全体大会选举李四光为苏联科学院院士,并授予卡尔宾斯基金质奖章;该奖章是1947年由当时的苏联科学院和俄罗斯科学院共同发起的、对地质科学有突出贡献的科学家最高单人奖励,李四光是第六位获奖人,也是至2017年止唯一获此殊荣的外籍地质学家,他的获奖理由是:在地质、古生物、地层和矿产研究工作的综合贡献。李四光有两部著作在苏联被译成俄文出版,分别是1952年的《中国地质学》和1958年的《中国西北部的旋卷构造》,这两部译作对当时的苏联地质界产生了很大影响,极大地推动了李四光学术思想的广泛认知;"地质无国界",中国地调百年的发展历程也有着俄罗斯地学理论、规范、方法实践的烙印,在新的"一带一路"合作倡议和李四光学术精神传承下,中俄、中国与中亚在地学领域的交流合作将不断深化,硕果累累。

斯特列利措夫矿田一个大型-超大型铀矿床群在苏联时期是怎样被发现和被勘探的

斯特列利措夫（简称Str）矿田是一个主要由大型-超大型钼铀矿床构成的矿床群,它位于南滨额尔古纳地区,铀的总储量在25万t以上,平均品位0.20%。该矿田在苏联解体以来的很长时间内几乎是俄罗斯唯一的天然铀来源。该区找铀的工作历程漫长而曲折,并颇具传奇色彩。早在1948年苏联地质部第一局松林大队在南滨额尔古纳地区开始了找铀工作。但因区内几乎所有矿床均属盲矿,而且多埋深较大,1962年之前找铀无果,1962年春已决定放弃在该区进行的找铀工作。1962年夏天高级地质师Л П伊舒科娃参观了哈萨克斯坦产在酸性火山岩中2个规模不大的铀矿床（波统-布鲁姆和克泽尔-萨伊）,注意到斯特列利措夫萤石脉围岩霏细岩的蚀变与哈萨克斯坦2个规模不大的铀矿床相似。归来之后,她上书领导力主恢复本区找矿工作并获得了再去做最后一试的机会。1963年5月,伊舒科娃所设计的钻孔一箭中的,发现了首个Str超大型铀矿床,整个局面立刻出现大转折,加速矿田开发成了所有工作的总方针。矿床的普查勘探工作和对矿床的地质研究工作平行加速进行,两者互相促进。不到10年,矿田的大部分矿床被一一发现;到1966年底,Str等矿床的初勘成果已经成为1970年代初组建全苏最大铀矿山的充分依据。到1980年底,矿田已有17个钼铀矿床完成勘探。1992年底19个矿床勘探完成。新一轮找矿采用的方略：首先合理综合运用地质、放射性及传统地球物理和地球化学方法,并合理综合使用深度普查自动装置射孔和钻探手段,进行不同比例尺的立体地质-构造填图;然后在其成果的基础上用钻孔去发现矿体。勘探工作所面对的基本事实：矿床构成的多重复杂性为Str矿田内所有矿床的共同特征;每个矿床的特点各异,其勘探过程不尽相同。初勘使用地表钻探进行,基本网度200 m×100 m~400 m×100 m。详勘使用坑探工程与钻探相结合的手段,采用水平与垂直断面联合的勘探系统,基本网度50 m×20 m~50 m×25 m。所有矿床的勘探成果完全被开采工程证实,并有10%的储量增长。Str铀矿床形成于晚中生代,为区域构造-岩浆活化作用晚阶段的陆相火山作用地区的岩浆热液矿床,受断裂构造控制是其基本特征之一。铀矿床在矿田内空间定位的重要规律：Str及其他绝大多数铀矿床均受控于南北向、北西向或东西向断裂与北东向额尔古纳隐伏深断裂带交汇。"斯特列利措夫效应"曾迅速地在我国铀矿地质勘查工作中传播,期待在我国,尤其在呼伦贝尔,乃至大兴安岭-燕山山脉中生代构造-岩浆带地区继续发酵,取得更多和更大的成果。     

Perspectives in reconnaissance for coastal-marine placers on southern and western continental shores of Okhotsk Sea

The resource base for the Russian tin industry is surveyed district by district, with emphasis on deposit geology and mineralogy, world and domestic market conditions, production linkages between mines and processing facilities, and exploration activity. Current Russian output is less than one-half the former Soviet total of the mid-1980s, a reflection of difficult economic conditions, divergent interests of mine producers and the management of the Novosibirsk tin smelter, and declining ore tenor at certain major deposits. Major deposits now are found exclusively in Russia's Far East economic region, often in remote and climatically inhospitable locations. Unlike most other major producing countries, the bulk of Russia's output comes from lode deposits rather than placers. A concluding section outlines factors expected to affect future tin demand in Russia and describes efforts to identify potentially promising nontraditional tin ore deposits.     

矿产勘查地球化学:过去的成就与未来的挑战

勘查地球化学经过 70年的发展 ,已从矿产勘查从属地位的一种战术手段上升到能左右整个矿产勘查全局的战略地位 ,并且从一门经验或技术 ,发展成为一门地学分支科学。这主要表现在 (1)系统地建立了各种类型的地球化学分散模式 ,并根据这些分散模式所形成的地球化学异常去追踪和发现矿床的理论 ;(2 )发展了各种尺度和各种不同介质的地球化学采样方法 ,多元素高灵敏分析方法和数据处理与图件表达方法 ;(3)发展了不同尺度 (局部、区域、国家和全球 )地球化学填图理论 ,一些国家开始陆续完成和出版了区域性或国家性地球化学图 ;(4 )在全世界发现了一大批新的矿产地 ,包括从 2 0世纪 30年代一直延续到 70年代在前苏联、北美和南美发现的许多斑岩铜矿 ,70年代在北美发现许多铀矿 ,80年代开始在中国发现数百个金矿。勘查地球化学尽管取得了从理论到实践的很大成功 ,但它也面临如下的挑战 :(1)全球各种介质中的地球化学基准与全球地球化学填图 ,(2 )隐伏区三维地球化学分散模式、深穿透地球化学与隐伏区矿产勘查 ,(3)巨量金属的聚集机理、地球化学块体与大型矿集区或巨型矿床的定量评价 ,(4 )难识别矿种或难识别类型的地球化学勘查与评价方法。     

On the possibility of new discoveries in the Strel’tsovka ore field

As further development of ideas stated by F.I. Wolfson on principles of uranium ore localization in the Strel’tsovka ore field, a possibility of an increase in uranium reserves in the northern portion of this ore field is substantiated. A large caldera, which is not less than the Strel’tsovka caldera in dimensions, is suggested beneath Cretaceous sediments in the northern portion of the ore field.     

Professional women and the economic practices of success and survival before and after regime change: diverse economies and restructuring in the Russian Republic of Buryatia

Drawing from historical research, participant observation, and informal and formal interviews, we examine the economic experiences of professional Buryat and Russian women before and after the collapse of the Soviet Union in the Siberian Russian Republic of Buryatia. We use a diverse economies framework to theorize a broader understanding of the restructured economy and how women have sought to improve and maintain their lives by developing various practices in the workforce in both the Soviet and post-Soviet periods such as gaining more education, informal networks of exchanges and favors, urbanization, and, for Buryats, Russian language acquisition. We argue that women in the early 2000s continue to employ many of these practices regardless of their varying experiences and attitudes about the transition from socialism to a market economy.     

Natural organic matter and its implications in uranium mineralization

Uranium is so intimately associated with carbonaceous matter in marine black shales and some sands tone-type uranium deposits that it is said to be “fixed” by organic matter. But different kinds of organic matter are not of equal importance in the geochemistry of uranium. The nature and origin of organic matter in uranium deposits and its role in the transport and concentration of uranium are different from place to place. The reason why uranium is closely associated with certain types of organic matter (for example, humus or bitumen) is described in this paper from geochemical viewpoint. Many uranium deposits and uranium occurrences have been found both at home and abroad. The distribution and existing forms of uranium in these deposits, and the concentration of uranium and element association in the ore are directly or indirectly related to organic matter. This paper is intended to discuss the types of natural organic matter and the mechanism of uranium transport and enrichment by organic matter, on the basis of author’s research work in conjunction with previous data.     

砂岩型铀矿床层间氧化带前锋区稀有元素富集机制

在深入研究砂岩型铀矿床层间氧化带各地球化学分带中铀及其伴生元素的分布规律时,发现一些单价态(不变价)元素也常常富集在层间氧化带前锋区,其典型代表是钪(Sc)、钇(Y)和稀土元素(REE)等。作者在综合分析前苏联众多砂岩型铀矿床各地球化学分带中各种元素大量测试数据的基础上,论述了层间氧化带前锋区Eh值和pH值的变化规律以及它们所导致的变价元素(U、Se、Mo和V)和不变价元素(Sc、Y和REE)的分布规律和富集机制。实际上,层间氧化带前锋区既是氧化-还原电位(Eh值)又是酸碱度(pH值)的急剧变化区,两者大致同步消长。层间氧化带前锋区有两类地球化学障:单纯的还原障和还原-碱性综合障。两种地球化学障的发育与强度取决于原始未氧化岩石中硫化物、有机质和碳酸盐的含量。     

金属矿床地电化学勘查方法研究现状及前景展望

地电化学勘查方法是20世纪70年代兴起的找寻隐伏矿床的新方法之一,包括地电提取法和土壤离子电导率测量法。它从20世纪70年代到90年代末这30多年的发展中一直被地学专家列为新的前缘课题来研究,它所提取的成矿信息来自于深部矿体,这一点经国内外科研工作者多年的找矿实践所证实,毋庸质疑。由于前苏联研制的“部分提取金属法”设备笨重、野外工作效率低、成本高而一直未能得到普及应用,随着方法技术的不断改进,其适用范围有所扩展,为地电化学方法找寻隐伏矿床开拓了广阔的道路。     

Russia's Silver Resources: A Post-Soviet Assessment

The current status of silver production in Russia (and areas in other former Soviet republics) is discussed with particular attention to mine output, deposit geology, byproducts, economics of production, and potential export markets. In Russia and elsewhere in the former Soviet Union, most silver is found and recovered in subordinate or trace amounts in deposits mined primarily for other commodities (especially gold and various base metals). Kazakhstan and Russia are the major mine producers of silver in the region, although in Russia potential demand is forecast to exceed output by as much as 25% by 1994. This potential shortfall, coupled with the approaching depletion of rich deposits in the Urals and northern East Siberia, has prompted the Russian government to formulate a plan for revitalizing the silver industry by opening new deposits and installing new processing capacity. A major objective of the plan, which attempts to reduce imports of silver concentrate and metal products, is increased foreign investment via international tenders. However, given the recent history of weak world silver markets, and an abundance of competing investment opportunities for global capital, it appears that Russia may have to consider incurring the costs of opening new silver deposits or relying more on imports.

亚洲砂岩型铀矿区域分布规律和中国砂岩型铀矿找矿对策

20世纪80年代以来,继中亚（哈萨克斯坦,乌兹别克斯坦）早所发现大量砂岩型铀矿之后,俄罗斯,蒙古境内又找到了许多大型砂岩型铀矿床,至此,亚洲已成为世界上砂岩型铀资源的最集中产地,已发现的砂岩型铀矿床大体上沿着南北分别为塔木－华北陆地和西伯利亚陆块所围限,西起西西伯利亚低地,向南经哈,乌,再折向东经阿尔泰,萨彦,我国的青,甘,内蒙,直到大小兴安岭和鄂霍次克海的近东西走向,向南凸出的弧形构造带分布,俄罗斯将其命名为中央亚洲活动带,我国一些学称其为蒙古弧,此带内产出成因迥异,类型众多的大型,超大型金,多金属,块状硫化物,斑岩铜（金）矿以及火山岩型和砂岩型铀矿,带内如此丰富多彩的矿产资源与该带独特的地质构造演化密切相关,今后应大力加强对此构造带的地质研究和铀矿找矿。
