矿床成矿系列与成矿区带融合关系的探讨

矿床成矿系列（以下简称成矿系列）是矿床或矿床类型组合的自然分类,是矿床地质科学和矿产资源评价中研究成矿规律的成矿学理论之一。矿床在自然界并非单个（或孤立地）存在,它们靠成因联系,并相互依赖着构筑成矿床组合的自然体,赋存在与成矿作用相匹配的特定的地质构造单元中,构成一个矿床成矿系列。即：在一定的地质历史时期或构造运动阶段;在一定的地质构造单元及构造部位;与一定的地质成矿作用有关;形成一组具有成因联系的矿床组合自然体,称为矿床成矿系列（陈毓川等,2006）。特定的时间域是指一定的地质历史发展阶段内一个大地构造活动旋回（或相对独立的构造活动阶段）;特定的空间域是指一定的地质构造单元,亦就是成矿的地质构造背景,一般相当于形成的三级构造单元（或跨越、或包含在老的构造单元内）;特定的地质成矿作用是指特定的时、空域中发生的地质成矿作用,即岩浆成矿作用,沉积成矿作用（在水体中沉积成矿）,变质成矿作用,表生成矿作用,与岩浆、变质成矿作用无关的流体成矿作用（陈毓川等,2015）;并形成有成因联系的矿床组合的自然体。

科学找矿工作的探索——兼述战略性矿产找矿工程

科学找矿是发现矿床和矿产勘查过程的总称, 在我国已探索了四十余年。它是应用当代有效的成矿学理论, 从各类资料和数据(地、物、化、遥)中提取信息, 研究区域成矿规律, 圈定不同级别的成矿区带(I—V级), 在成矿信息浓集区带或地段, 述明潜在矿床的地质条件, 判定矿床类型, 指明寻找未发现矿床的标志, 部署矿产勘查后进而发现了矿床, 公认它是矿产勘查学科各环节有机联系的系统流程。科学找矿引领地质找矿的重大突破, 促进矿产勘查工作的现代化。我国已通过矿产区划构建了科学找矿内容的基本格架, 在“新一轮固体矿产普查”、“矿产勘查跨世纪工程”、“矿产资源调查评价”和“找矿突破战略行动纲要”(又称“三五八”行动纲要)的实践中进行探索。获取的找矿成果证明, 科学找矿要以矿床成矿系列、矿产预测理论和成矿信息为指导; 矿产远景区划、地质资料的数据处理和提取成矿信息、编制矿产预测和矿床勘探系列图件是手段; 研究典型矿床, 建立区域的和矿床的成矿模式、总结区域成矿规律、圈定矿产预测远景区和找矿靶区、部署矿产勘查工作是发现矿床的科学支撑; 矿产勘查有效机制将科学找矿各个环节的内容实现有机联接, 组成获取找矿和矿床勘探成果的基本段, 概括为“三项理论”、“二个系统”、“二项技术”, 直至今日, 探索工作已获得很好的找矿效果。在未来的“战略性矿产找矿行动(2021—2035年)”实施过程中, 用科学找矿的思路构建矿产勘查新格局。

成矿模式研究的几个问题

成矿模式是当代矿床学研究的重要内容和发展方向，是矿床地质科学在描述性基础上发展到高度理论性的必然产物。成矿模式是在区域成矿学研究和典型矿床研究的基础上建立的，它不仅有助于人们深化对矿床特征和矿床成因的认识，而且对矿产预测和勘查工作具有日益重要的指导作用。作者根据成矿模式的概念和研究成果，提出了新的矿床分类设想，并就成矿模式与成矿系列的关系等问题进行了有益的探讨。

Unity of the national and the international in the socio-cultural development of the peoples of the USSR

International unity is becoming ever stronger in this country owing to an increasing similarity in the development of the cultural environment. This comprises the provision of all the country's republics with a sufficient number of schools, theatres, and other institutions and cultural information media in accordance with the needs of the population. An important part is played by the rise in ‘the general educational level, as well as the level of professional qualifications and skills. Among all the Soviet nations and nationalities, this rise being more rapid among formerly backward peoples. Prominent among the factors of internationalization is the progressive development of the nationalities’ cultural resources, while professional culture is being increasingly brought within the reach of the masses.The implementation of the nationalities policy promotes the all-round development of all Soviet nations and nationalities, their drawing together, the upsurge of the individual capabilities of every Soviet citizen.     

Report of the restudy of the defined global stratotype of the base of the Silurian System

The Global Stratotype Section and Point （GSSP） for the base of the Silurian System was defined in 1985. Since that time, a number of researchers have suggested that this section has serious deficiencies for use as a GSSP. As a result, in 2000, the Subcommission on Silurian Stratigraphy （SSS） proposed undertaking a formal restu@ of this GSSP, which was subsequently approved by the International Commission of Stratigraphy （ICS）. The result of this restudy was the formal proposal that the current GSSP, at 1.6 m above the base of the Birkhill Shale, at Dob＇s Linn, Scotland, should be maintained as the same locality and stratigraphic level, but the bios- tratigraphical definition of the boundary should be revised. The previously defined, basal Silurian grapto- lite zone, the Parakidograptus acuminatus Zone, should be subdivided into a lower Akidograptus ascensus Zone and a higher E acuminatus Zone. The base of the A. ascensus Zone, marked by the first appearance of A. ascensus, should be regarded as the biostratigraphic mark for the base of the Silurian. This proposal has now been formally approved by the SSS and ICS, and ratified by International Union of Geological Sciences. This is the first GSSP to undergo formal restudy and redefini- tion, and the proposal also included a recommended procedure for restudy of GSSPs.     

Deviation of the major axis of the inertia ellipsoid of the Moon from the direction toward the Earth

It is known from observations that the center of mass of the Moon does not coincide with the geometric center of its figure, and the line connecting these two centers is not aligned with the direction toward the center of the Earth, instead deviating toward the Southeast. This stationary deviation of the axis of the inertia ellipsoid of the Moon to the South of the direction toward the Earth is analyzed. A system of five linear differential equations describing the physical libration of the Moon in latitude is considered, and these equations are derived using a new vector method taking into account perturbations from the Earth and partly from the Sun. The characteristic equation of this system is obtained, and all five oscillation frequencies are found. Special attention is paid to the fifth (zero) frequency, for which the solution of the latitude libration equations are stationary and represents a previously unknown additional motion of the rotational axis of theMoon in a cone with a small opening angle. In contrast to the astronomical precession of the Earth, the rotation of the angular-velocity vector is in the positive direction (counter-clockwise), with the period T ₃ = 27.32 days. On this basis, this phenomenon has been named “quasi-precession.” This quasi-precession leads to a stationary inclination of the major axis of the inertia ellipsoid of theMoon to the South (for an observer on Earth), making it possible to explain one component of the observed deviation of the center of mass of the Moon from the direction toward the Earth. The opening angle of the quasiprecession cone is approximately 0.834″.     

The Tendencies of the Development of the Mineral-Resources Sector at the Turn of the Century

Important tendencies in development of the world mineral-resources sector at the beginning of the 21st century were an increase in production and consumption of mineral materials differentiated by types of metals and nonmetallic mineral raw materials, by countries and regions, as well as the concentration of the production of mineral raw materials in a small number of countries, and a reduction in industrial reserves of minerals in the world economy, even at the current stage of their extraction. These tendencies should be taken into account in working out a strategy for development of the Russian mineral raw-material base.     

Causes of the famine among the rural population of the Sahelian zone of the Sudan

Taking the example of W Sudan, an analysis of the climatic incidents leading to the two recent famine disasters is made. On this natural background, the human side is investigated. Focus is directed towards the fragile economic structure of the famine-prone population groups. An early-warning system for famine in the Sahelian Zone is proposed taking grain production and storage, livestock development and the relationship between the prices of livestock and grain as major indicators.

The Importance of the Precipitation and the Susceptibility of the Slopes for the Triggering of Landslides Along the Roads

In order to characterise the influence of the heavyrains on the observed landslides during the 1996–1997hydrological cycle, rainfall records for the last 100years are analysed from 104 stations in easternAndalusia. Regarding the amounts of rain recordedbetween October 1996 and March 1997 in the 104stations studied, 31 presented new all-time records;15 presented values that were 80–100% of thepre-1995 record; 49 stations, 80–50%; and 9stations, < 50%. A map has been devised of thesusceptibility of the materials through which thesouth-eastern Andalusian road network crosses,together with an inventory of the damage caused byinstability phenomena on banks and cuttings of theroad network during the winter of 1996–1997. Therelationships between the rainfall during the studyperiod, the damage caused to the road network and thesusceptibility of the materials affected are analysed.The results indicate that there is a clearcorrespondence between the rainfall recorded and thesusceptibility of the materials with the inventorieddamage. It is concluded that the widespread seriousdamage caused in early 1997 to the roads andsurrounding areas in the Alpujarra region and thecoast of the Province of Granada was mainly caused bythe extraordinarily heavy rains. However, considerablyless damage was observed where the susceptibility ofthe terrain is low, thus highlighting the extremeusefulness of terrain-susceptibility maps for riskprevention and territorial planning.
