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入认识进程。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。
Most of the worldrs 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 in- dispensable 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.
