传统的板块构造理论提供了解释大陆板块边缘成矿问题的理论框架，但对解释板块碰撞后大陆内部演化阶段的成矿作用则无现成答案。基于这一现状，20世纪90年代以来，以发展板块构造理论、深入理解大陆成矿作用、提高发现大陆内部矿床能力为主要目的的大陆动力学及其与成矿关系的研究，引起了国际地学界的高度重视。纵观近年大陆动力学与成矿关系的研究，可以发现以下若干趋势：在成矿机制上，将成矿作用研究与壳幔相互作用研究密切结合；在成矿时代上，成矿作用与重大地质事件的内在关联受到高度重视；在成矿区域上，除继续重视板块边缘成矿作用的研究外，大陆板块内部的成矿作用成了新的研究热点。 |

Traditional theory of plate tectonics provides theoretical basis for understanding continental plate margins, but it is difficult to explain the post-collision mineralization during mineralization in the the evolutional stages in the intra-plate settings. Therefore, the international geological community highly focuses on the relationship between continental geodynamics and mineralization since the 1990＇s, which aims at developing the plate tectonic theory, thoroughly understanding the continental mineralization and thus improving the ability of finding ore deposits associated with intra-plate circumstances. In combination with recently related studies, several directions have been realized： mineralization tied by crust-mantle interaction concerning the ore-forming mechanism; focus on the genetic relationship between mineralization and important geological events involving in the ore-forming ages; and mineralization related to the intra-plate settings being newly hot topic beside the continuously concentrated mineralization in the continental margins for the metallogenetic regions. |
