摘　　要：大红山矿区位于滇中台坳南缘,在漫长的地质演化过程中,区内经历了复杂的构造—岩浆活动,成矿条件优越,大红山铁铜矿床既是区内典型的大型矿床。矿床经过多年开采,揭露了多种矿(化)体类型。为进一步查明矿床成矿机理,在野外地质调查及找矿勘探成果的基础上,综合分析了成矿地质背景、矿化(体)地质特征,系统厘定了成矿条件,探讨了成因机制及找矿方向,综合判定大红山—元江地区、矿区北部的元谋—姜译地区及红河断裂、底巴都背斜等构造有利部位为“大红山式”铁铜矿的找矿靶区。Dahongshan mining area is located in the southern margin of middle-Yunnan Province,during the long geological evolution process,the mining area is experienced a long and complex tectonic-magmatic activity,which characterized by superior metallogenic condition.Dahongshan Fe-Cu Deposit is a typical large deposit in this region. It is experienced long-term mining activities,the (mineralization) ore-bodies are revealed.In order to further study the metallogenic mechanism,the metallogenic background,geological characteristic of orebodies (mineralization) are analyzed in detail,the metallogenic conditions are summarized and the genetic mechanism and prospecting direction are discussed.Based on the field geological surveying and mineral exploration results,it is further indicated that Dahongshan-Yuanjiang area,Yuanmou-Jiangyi area in northern mining area,Honghe fault and Dabadu fault are the favorable prospecting targets for "Dahongshan type" ore.
