摘　　要：德兴韧性剪切带是金山金矿田的主要控岩控矿构造,渔塘金矿是金山金矿田的重要组成部分。本文通过地质勘查、岩芯编录、坑道编录对渔塘金矿进行综合分析及研究,发现渔塘金矿床赋存于新元古界双桥山群变质岩系中,渔塘金矿的形成受推覆型韧性剪切带构造控制,韧性剪切带是最主要的找矿标志。由此推断渔塘金矿床成因为韧性剪切带控制的变质热液型金矿,该区域金矿田的成因属于受韧性剪切带控制的动力变质热液型金矿。研究成果对区域上类似金矿床的成因研究具有一定借鉴意义。The Dexing ductile shear zone is main rock-control and ore-control structure located in the part of Jinshan gold ore field, Yutang gold deposit is the important part of Jinshan gold ore field. In this paper, the research and analysis of Yutang gold deposit by geological survey, drill core record compiling, mine opening geological record compiling, the Yutang gold deposit was found occurs in metamorphic rocks of the Neoproterozoic Shuangqiaoshan group, the formation of gold mine is controlled by ductile shear zone of the nappe tectonic, the ductile shearing zones are the main prospecting signs in this area. It can be concluded that it is metamorphic hydrothermal gold and the genesis of gold fields belongs to dynamic metamorphic hydrothermal gold deposits controlled by ductile shear zone.
