摘要
达斯呼都格铅铜银多金属矿床共圈定10条矿体,矿床成因类型为陆相火山-次火山中低温热液矿床。其中1、2、3号矿体产于火山机构边缘部位的火山角砾岩中,其余7条矿体均产于火山机构外围塔木兰沟组地层玄武岩内的构造破碎带中,1、2、5号三个矿体规模较大。次火山岩、火山岩筒和断裂构造是找矿的宏观标志,地球物理和地球化学是重要的找矿手段和标志。
Dasihuduge Pb-Cu-Ag Polymetallic deposit have delineated total 10 ore bodies, the genetic type of the deposit is volcano-volcano in liquid and low temperature hot continental deposits. 1,2, 3 ore bodies occur in the edge of the volcano volcano mechanism in breccia, the other 7 ore bodies are occurred in the tectonic volcano organization peripheral Tamulan ditch formation basalt within the fracture zone, 1,2, 5, three ore body scale. A volcano volcano rock, rock tube and fracture is the macroscopic marks of prospecting, geophysical and geochemical prospecting is the important means and mark.
