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 clastic sediments��while the Huanglong Formation is mainly carbonate rocks in nature�� The unconformity interface between the two formations is weak in structure��which benefits for the aggregation of metallogenic elements and the major horizon of ore-bearing in the belt��and the horizom is also the key position for deep prospecting in future��
