成矿系统:地球动力学的有效探针

Ore-system as a geodynamic probe

笔者介绍了矿床研究促进地球动力学或大地构造研究突破的实例,证明成矿系统是理想的地球动力学探针。其原因之一是成矿系统往往由多种地质作用综合作用形成,更全面地记录了地质作用的信息;原因之二是矿床的研究程度高于其他类型的地质体,能够更准确地给出地球动力学演化的信息。作为尝试,笔者初步建立了重要成矿系统与地球动力学背景之间的链接,提出了一些似可通过成矿系统研究而解决的重要科学问题。

In this paper we introduce several breakthroughs in geodynamic or tectonic issues resulted from studies on ore-systems, and propose that ore-systems can serve as an ideal geodynamic probe. Usually formed in multiple geological processes, ore-systems record complete geological information. Compared to other kinds geologic bodies, ore-systems are more precisely studied through prospecting and/or mining. As a consequence, ore-systems can provide accurate indicators to geodynamic settings and evolution. We set up a preliminary linkage between major ore-systems and geodynamic settings; and propose several important scientific approaches for solving long-standing geodynamic controversies by the study of ore-systems.
