成矿系统研究与找矿

Research on Metallogenic System

成矿系统研究适应了地球科学系统化的发展趋势,是当今矿床学研究的重要内容之一。本文中在对成矿系统的定义、结构、要素、作用产物等进行论述的基础上,提出成矿系统研究的4个要点:①按构造动力体制划分成矿系统大类;②多因耦合、临界转换的成矿作用机理;③矿床系列和异常系列构成的矿化网络;④矿床形成变化—保存的演变过程。作者明确了成矿系统研究应从矿化网络入手的方法,总结了矿化网络研究的主要内容,提出了通过成矿系统研究发现新类型矿床的几个途径,分析了成矿系统研究的资源环境效应,并探讨了成矿系统研究的理论意义。

The research on metallogenic system meets the trend of systematization of Earth sciences. It becomes one of the most important research contents of ore deposit geology. Based on the study on the concept, structure, elements and products of the metallogenic system, the author emphasizes four main points in the research of metallogenic system. (1)Major types of metallogenic system are classified by tectono-dynamic system; (2)Coupling of many factors and criticality-transition are basic ore-forming mechanism; (3)Ore deposit series and anomaly series constitute the mineralization network; (4)The evolutionary process of an ore deposit includes its formation, transformation, and also preservation. In addition, the author puts forward that research of metallogenic system should start from the study of mineralization network. Main contents of research on mineralization network are summarized and several ways to discover new-type of ore deposits with the research of metallogenic system are pointed out in this paper . Finally, effect on mineral resource and enviromnental protection and theoretic significance of the research on metallogenic system are discussed.
