摘要
成矿系统是当今矿床学研究的一个重要课题，是矿床学向系统化、全球化方向发展的一种趋势。成矿系统是指在一定地质时空域中，控制矿床形成和保存的全部地质要素和成矿作用过程，以及所形成的矿床系列和异常系列构成的整体，它是具有成矿功能的一个自然系统。成矿系统是在一般矿床成因研究的基础上，着重从宏观上，从成矿的时间、空间、物质、运动的有机结合上，探讨区域尺度的成矿规律。其研究意义是深入认识成矿动力学机制，指导矿产勘查，并有利于将成矿学信息应用到地学其它学科中去。文中还论述了成矿系统与成矿系列、成矿区带的联系和区别，对成矿系统的基本要素、作用过程、作用产物和成矿后变化及保存４个问题作了说明。提出以成矿的构造动力体制作为划分成矿系统大类的依据及以成矿机理作为划分成矿系统类型的主要标志。最后以古大陆边缘构造成矿系统为例，说明构造动力型式。
Metallogenic system is an important topic in the study of geology of ore deposits It is also a symbol to show the systematic and globalizing tendency in the metallogenic research Metallogenic system, often within a certain geological time space realm, is a natural system with ore forming function.It includes geological factors controlling ore formation and preservation, ore forming processes and its products ore deposit series and anomaly series Based on the study of the genesis of ore deposits, metallogenic system discusses regional metallogeny in a macroscopic way by combining metallogeny with time, space, substance and movement Its study significance lies in: (1) to understand deeply the mechanism of metallogenic dynamics;(2) to guide the exploration of ore deposits ; (3) to promote the application of metallogenic information to the other disciplines of geosciences This paper discusses the relation and difference among metallogenic system, metallogenic series and metallogenic district and also illustrates basic factors , processes, products, variation and preservation of metallogenic system In addition, this paper suggests to classify the principal types of metallogenic systems according to their different tectono dynamic framework and to classify the secondary types according to their ore forming mechanism Taking tectono metallogenic system in the paleo continental margin as an example, this paper explains the relationship among the tectono dynamic framework, structural association and metallogenic system in its last part
