云南东川播卡金(铜)矿区辉绿(辉长)-钠长岩系岩相学及其成矿意义

On diabase( gabbro)-albite rock petrography and genetic significance in Au( Cu) mine in Boka of Dongchuan in Yunnan

云南播卡金(铜)矿床构造上位于小江断裂西侧,新近勘查工作表明,其金(铜)矿体的赋存于辉绿(辉长)-钠长岩系有密切的成因联系。进一步研究表明,除构造控矿因素外,岩浆热液中碱金属元素(K、Na)的活动交代也是金(铜)矿床形成的重要因素。

Boka Au（ Cu） deposit was tectonically located in the west side of Xiaojiang fault zone and through latest exploration work,the occurrence of Au（ Cu） ore bodies were genetic closely related with diabase（ gabbro）-albite rock series. Further studies demonstrated that the activity of alkali metals like K and Na in magma thermal fluids formed the important factors for the formation of Au（ Cu）deposit.
