摘　　要：池州地区位于我国长江中下游铁、铜、金成矿带的南带内,已发现各类矿产地超200处。本文选取区内6个不同规模和矿化类型的矿床,通过测试各矿床的矿石、围岩、精粉和尾砂等样品,分析其伴生稀散元素含量的情况。分析结果显示:目标矿床均有不同程度和种类的稀散元素矿化富集,以Cd、Ga元素最为普遍,少数矿床可见到Te、Tl、In、Se和Ge元素富集,并与矿种具有一定程度的对应关系。在此工作基础上,结合已有资料,初步探讨区内稀散元素的成矿规律和找矿方向。The Chizhou area is located in the southern part of the iron,copper and gold metallogenic belt along the middle and lower reaches of the Yangtze River in China,and more than 200 significant ore occurrences of different kinds have been found in the area.In this paper,we chose six deposits of different sizes and different mineralized types in the area,and analyzed the contents of associated scattered elements by testing the samples of ore,wall rock,concentrate fine and tailing of each deposit.The results indicate that the chosen deposits are enriched with different types of scattered elements which are mineralized to different degrees,Cd and Ga are the most common,Te,Tl,In,Se and Ge can be found in a few deposits,and there is a correspondence between these elements and specific minerals.Based on the above work and available data,a preliminary study was made on the metallogenic regularity and targets of the scattered elements in the area.
