昭通彝良发达铅锌矿控矿特征及找矿标志研究

Ore control characteristics and prospecting criteria of Yiliang developed lead-zinc deposit Zhaotong

矿区位于扬子准地台西部边缘之滇东北台褶束的中北部,属川滇黔毗邻区成矿域之滇东北成矿带的中部地段,成矿地质条件较好。本文对矿区地层、构造、蚀变特征及矿(化)体特征进行详细分析,进而对矿区成矿潜力及找矿标志进行深入研究,研究结果对矿区以后的找矿工作具有很重要的指导意义。

The mining area is located in the north central part of the Northeast Yunnan platform fold in the western edge of the Yangzi para platform,which belongs to the central part of the northeastern Yunnan metallogenic belt in the adjacent area of the adjacent area of Sichuan,Yunnan and Guizhou Province,and the metallogenic geological conditions are better.In this paper,the characteristics of formation,structure,alteration and orebody of the mining area are analyzed in detail,and the metallogenic potential and prospecting mark of the mining area are further studied.The research results have important guiding significance for prospecting work after the mining area.
