乐华—德兴成矿带成矿作用研究的进展、问题及展望

The Ore-Forming Processes of the Lehua-Dexing Metal logenic Belt in Northeast Jiangxi: Its Research Progess, Current Problems and Prospects

赣东北乐华—德兴成矿带位于江南地块东南缘。带内有超大型的德兴斑岩铜矿床、金山金矿床、银山多金属矿床以及许多中小型矿床,其中铜储量和伴生金储量分别占全国的17.5％和37％。深入研究乐华—德兴成矿带内典型矿床和区域成矿作用,对深刻揭示大型—超大型矿床的成因、矿床分带的形成机理以及发展中国的金属成矿学理论等都有重要意义。本文讨论了近年来对该成矿带成矿作用的研究进展、存在问题,并对研究前景作了展望。

The Lehua-Dexing metallogenic belt in northeastern Jiangxi is located on the northeast margin of the Jiangnan massif, where there are the super-large Dexing porphyry copper deposit , the super-large Jinshan gold deposit and the large Yinshan polymetallic deposit as well as many medium and small deposits. The copper and gold reserves in the belt account respectively for 17. 5 per cent of copper reserves and 37 per cent of gold reserves of associated gold deposits (in which gold occurs as a valuable component in ores) of the whole country. Intensive study of the representative deposits and regional ore-forming processes of the Lehua-Dexing metallogenic belt has great significance for revealing the genesis of large and super-large deposits, bringing to light the formation mechanisms of zoning of ore deposits and developing the metallogeny of ore deposits. In this paper, new advances in the study of the ore-forming processes of this metallogenic belt are reviewed and the current problems in the study discussed. Finally, the research prospects on the ore-forming processes are presented by the author.
