| 摘 要： | 长江中下游地区是中国东部重要的铁铜金多金属成矿带。经对比，长江中下游大多数地区的泥盆系五通组与石炭系黄龙组之间有明显的沉积间断，为假整合接触关系。两组岩性差异较大，五通组主要为陆相碎屑沉积，而黄龙组为碳酸盐岩。泥盆系五通组与石炭系黄龙组之间的不整合界面是构造薄弱面，利于成矿元素的聚集，是成矿带内主要的容矿层位，该层位应是今后深部找矿的重要层位。

| Abstract: | The metallogenic belt in middle-lower reaches of Yangtze River is a major Fe-Cu-Au polymetallic ore belt in the eastern China. There are significant hiatus between Devonian Wutong Formation and Carboniferous Huanglong Formation, which shows unconformity relationship between the two formations. The two formations are quite different in lithology that the Wutong Formation is mainly of continental elastic sediments, while the Huan- glong Formation is mainly carbonate rocks in nature. The unconformity interface between the two formations is weak in structure, which benefits for the aggregation of metallogenie elements and the major horizon of ore-bearing in the belt, and the horizom is also the key position for deep prospecting in future. |
