【摘要】：宝石矿床学是矿床学与宝石学之间的交叉学科,是联结宝石学与地质学的重要纽带。宝玉石是矿物岩石中的精美部分,是地球物质中的组成部分,是探索地球组成、特征与演化的重要研究对象。随着人们对宝玉石外观特征、特性与效应等成因认识的深化和新的宝玉石种类被发现并应用,宝玉石矿床学正在成长为集地质学与宝石学为一体的、内容丰富的学科。在文中回顾了宝石矿床学的历史与发展,总结了宝玉石资源的分布特点,提出了宝玉石成矿作用并做了简要论述,给出了宝玉石矿床的特点及宝玉石矿床学的研究特征。认为,宝石矿物或岩石的成矿作用是研究宝玉石矿床的基础,然而,要形成首饰级的宝玉石,还需要研究成宝、成玉作用。宝玉石中的很多特性与效应,如变彩、变色、变石、月光等效应的成因机理及特殊结构的研究还有待完善,而关于其在自然条件下形成机理等问题,很多是空白。总的来说,宝玉石矿床学研究内容还不完全、不够系统,很多宝石矿种的成因还停留在推测阶段。预计在很长时间内,宝玉石矿床学研究重点依然是单个矿床(已开采和新发现的)的资料收集与整理,不同产地同种矿物的宝玉石矿的类比与综合分析。
[Abstract]:Gemstone ore deposit is an interdiscipline between ore deposit and gemology, which is an important link between gemology and geology. Baoyu stone is a fine part of mineral rocks and a part of earth material. It is an important research object in exploring the composition, characteristics and evolution of the earth. With the deepening of people's understanding of the appearance characteristics, characteristics and effects of Baoyu stone and the discovery and application of new types of Baojadeite, Baoyu ore deposit science is growing into a rich subject which integrates geology and gemology. In this paper, the history and development of gemstone ore deposit are reviewed, the distribution characteristics of Baoyu mineral resources are summarized, the metallogenic process of Baoyu stone is put forward, and the characteristics of Baoyu ore deposit and the research characteristics of Baoyu mineral deposit are given. It is considered that the mineralization of gem minerals or rocks is the basis of the study of Baoyu ore deposits. However, to form jewelry grade Baojite, it is necessary to study the role of treasure formation and jade formation. Many characteristics and effects in Baoyu stone, such as color change, stone change, moonlight effect and so on, need to be improved. However, many questions about the formation mechanism of Baoyu stone under natural conditions are blank. In general, the study of Baoyu ore deposit is not complete and systematic, and the genesis of many gem minerals is still in the stage of speculation. It is expected that for a long time, the emphasis of the study of Baoyu ore deposits will be the collection and collation of data of single ore deposits (mined and newly discovered), and the analogy and comprehensive analysis of the same minerals from different habitats.
