我国的矿床地球化学研究在近十年取得了众多重要进展。本文对中国岩浆型Cu-Ni-(PGE)硫化物和Fe-Ti-V矿床、斑岩型铜矿床、花岗岩型钨锡矿床、碳酸岩型稀土矿床、卡林型金矿床和密西西比河谷型(MVT)铅锌矿床等的一些相关研究进展,以及原位分析技术和实验地球化学在矿床研究方面的应用进展进行了扼要论述。近十年来,造山带铜镍硫化物矿床的寻找取得突破进展,岩浆通道系统被证实对巨量钒钛磁铁矿的堆积起关键作用;碰撞型斑岩铜矿的成矿模型更趋完善,花岗岩相关钨锡矿床的成矿过程与机制获得更精细刻画,碳酸岩型稀土矿床的形成时限被精确限定;华南大规模低温成矿的时限和动力学背景研究取得重大突破,成矿物质来源和流体演化的认识更为深入;原位微区元素-同位素组成对精细刻画成矿过程发挥重要作用,实验地球化学的应用初现端倪。此外,本文还对未来需要重视的几个方面的工作提出了初步建议。 |

In recent decade,numerous important achievements for ore deposit geochemistry have been made in China. This paper briefly summarizes some progresses in the studies of magmatic Cu-Ni-(PGE)and Fe-Ti-V deposits,porphyry Cu deposits,granite-related W-Sn deposits,carbonatite-related REE deposits,Carlin-type Au deposits,and Mississippi Valley-type Pb-Zn deposits,and the implications of in-situ analytical methods and experimental geochemistry in researches of ore deposits. Notably,a breakthrough has been made in the exploration of magmatic Cu-Ni sulfide deposits in the orogenic belt,and a magma-conduit system has been confirmed to be critical for the huge accumulation of V-Ti-bearing magnetite. The metallogenic model for collision-type porphyry Cu deposits has been increasingly improved,and the ore-forming process and mechanism for granite-related W-Sn deposits has been more elaborately illustrated. The metallogenic timing for carbonatite-related REE deposits has been more precisely confined. Significant progresses in researches on timing and geodynamic background,as well as deep understandings on the sources of ore-forming materials and the evolution of ore-forming fluids for large-scale mineralizations of low-temperature hydrothermal deposits in South China have also been made. Moreover,in-situ micro-analyses of elemental and isotopic compositions have played important roles for elaborately illustrating the ore-forming processes,and applications of experimental geochemistry shed preliminary light on studies of ore-forming mechanisms of mineral deposits. In addition,several perspectives on future studies that need to be paid attention to have been proposed. |
