中文摘要:地球动力学演化过程与成矿作用是当今矿床学研究的前沿。文章回顾了自20世纪60年代以来,有关大陆动力学演化与成矿的研究历史和当前的研究动向。综述了几个研究大阶段,即:海底喷流成矿作用、大陆边缘成矿作用、板内成矿作用及地质历史演化过程的大陆汇聚或增生与多期次成矿。同时,以华南地区为例,将大陆侧向和垂向增生作为切入点,阐述了华南世界级有色、稀有、贵金属成矿省在地质历史过程中的成矿作用,并提出在该成矿省进一步实现找矿突破的重要科学问题。 |

Abstract:Geodynamic process and metallogeny constitute an important research field all over the world. Studying the tectonic evolution process we can get to know why some groups of ore deposits occur in some specific geological settings and why large amounts of metals are accumulated in some specific places of the metallogenic belts or regions. In this paper, a review is given concerning the research work conducted in this field since 1960's. Four important periods of researches have been proposed, i.e., the observation of the submarine exhalative ore system and the study of the similarities in the geological history in the present continents, the metallogeny along the mobile continental margins, the intra_continental orogenic and extensional processes, and the continent convergence or even terrain accessory and related metallogeny throughout the geological history. Exemplified by South China comprising Cathynian and Yangtze blocks, a world-class nonferrous metallic province, the authors propose three important lateral or vertical continental accessories and ore-forming processes throughout the geological history. They include Neoproterozoic Rodinia assembly and breaking up and related Sn-Cu_Ni mineralization, Emeishan mantle plume and related Cu-Ni-Pt-Pd-V-Ti mineralization, and Late Triassic assembly of Indo-China, South China and North China cratons and related Late Jurassic-Early Cretaceous large-scale non_metallic mineralization. |
