| 摘 要： | 本文试图通过小红石砬子银铅锌矿床产于火山穹窿构造环境、控矿与海相火山-沉积建造有关、热液蚀变种类与矿体在金属矿化、元素分布空间上具有分带性等特征,论证该矿床属于位于火山穹窿构造环境中的火山成因块状硫化物矿床。进而推测同处于吉中弧形构造带中的地局子、新立屯、二道林子、圈岭等赋存于上古生界二叠系火山-沉积建造中的多金属硫化物矿床也应同属于与火山作用有关的块状硫化物矿床。在此基础上提出有关省内地槽区块状硫化物多金属矿床的几点找矿评价标志。

| Abstract: | The Xiaohongshilizi silver lead-zinc deposit is occurred in volcanic dome structure setting,,ore-control was related to the marine volcano-sedimentary formations,hydrothermal alteration types have zonality and in metallic mineralization of ore body,and element distribution in space,demonstrated that the deposit belongs to volcanogenic-massive sulfide deposit in volcano dome structure environment.Speculate further,in the same central part-Jilin arc structure belt Dijuzi,Xinlitun,Erdaolinzi,Quanling etc.They all occurred in the polymetallic sulfide deposits of the upper Paleozoic Permian volcano-sedimentary formations,which also belong to massive sulfide deposits related to volcano effect.On this basis,put forward some prospecting and evaluation criteria of geosynclinals area massive sulfide polymetallic deposits within Jilin Province. |
