摘　　要：云南丽江-永胜地区夹持于丽江-木里断裂和程海-宾川深大断裂之间,二叠系火山岩广泛发育,火山岩系中由北至南分布有丽江拉马古小型铜矿、丽江文通小型铜矿、永胜米厘小型铜矿、永胜宝坪中型铜矿等。铜矿矿床明显受地层、火山岩、岩性组合、岩相古地理环境及构造等控制,成矿具有独特的特征和规律,属火山沉积+后期构造热液叠加改造型铜矿床。Lijiang-Yongsheng area of Yunnan is between Lijiang-Muli fault and Chenghai-Binchuan macrofault,with widely developed P volcanic rocks.In the volcanic rock series,there are small lamagu Cu deposit in Lijiang,small scale Wentong Cu deposit in Lijiang,small scale Mili Cu deposit in Yongsheng,middle scale Cu deposit in Yongsheng,etc,from N to S.They are controlled clear by strata,volcanic rock,lithic character assemblage,rock facies palaeogeographic environment and structure,etc.The metallogenesis is characterized by special rule,belonging to volcanic sedimentary+epigenetic structure hydrothermal superimposed reformation Cu deposit.
