| 摘 要： | 世界上绝大多数大矿床都是超级地质作用导致矿石异常集中的结果,一般多发生于一个地质作用结束的时期.地壳形成作用和板块构造、地幔柱模型已经成为如何认识矿床形成的关键所在,现代矿床成功的探索实践历史就是对大陆和海洋的深人认识进程.因此,矿床形成与全球构造和大陆的演化关系是研究成矿动力学的基础.本文以全球活动构造的视角,从超大陆聚散的历史纪录角度,对活动的地球演化环境下的成矿作用进行总结探索,以图激发对该领域更为深入的研究和思考.

| Abstract: | Most of the world′s great mineral deposits are the products of a superposition of geological processes which resulted in anomalous concentration of ores , generally occurred at the end of a geological period.Crust-forming processes and the global plate tectonic and mantle plumes paradigm have become indispensable to the broader understanding of how ore deposits form , and a successful exploration of modern ore deposits has been an appreciation of the history and evolution of the continents and oceans.Consequently , the relationship of the formation of ore deposits between global tectonics and the evolution of the continents is a study basement of ore-forming dynamics.In this paper , from the point of view of active global tectonics , and the rates of historic records of amalgamation and dispersal of the super-continents , we study the ore-forming processes in a setting of active global evolution in order to stimulate more further study and reflection of the field. |
