中文摘要:
      无论是与岩浆作用,还是与沉积作用或变质作用岩石相关形成的矿床均发生在地壳之中。事实上,成岩与成矿紧密的关系意味着要理解成矿作用就必须深入的认识整个地质时代地壳演化的特征。相应的研究有2个最基本的方向:其一是经验性的描述成矿构造环境和容矿岩石的研究;其二是构绘大陆演化与矿床在其演化中的时空位置的研究。前者已经获得相当多细致的研究;但后者研究上需要对大陆演化历史的全面理解,认识上就更为困难。特别是成矿作用传统认识上的局限性,难以将成矿作用置于活动的大陆聚散过程中去认识。笔者以全球活动构造的视角,从大陆生长速率、水圈和大气圈的演化、全球性热产物演变和海平面的变化的历史纪录角度,对活动的地球演化环境下的成矿作用进行总结探索,以激发对该领域更深入地研究。
英文摘要:
      The formation of ore deposits is, nevertheless, related to much the same sort of processes that gave rise to the formation of normal igneous, sedimentary, and metamorphic rocks in the Earth′s crust.The fact that close relationship exists between rock-forming and ore-forming processes means that metallogeny must be relevant to understanding the nature of crustal evolution through geological time. There are essentially two ways to do this. One is to empirically describe ore deposits in the tectonic environment and host rocks in which they occur. The other is to chart continental evolution and place ore deposits into a secular and tectonic framework. The former has been covered in considerable detail,and the latter is a more difficult undertaking and requires a thorough knowledge of the evolution of continents with time. It is difficult,particularly,that understanding ore-forming processes in amalgamation and dispersal of active continent by limitation in conventional undertaking. In this paper,it is applied that the point of view of active global tectonics, from rates of continental growth,evolution of the hydrosphere and atmosphere, secular evolution in global heat production into historic records of sea-level changes,to groping summary ore-forming processes in a setting of active global evolution in order to energizing more thorough research in this specialty.
