| 摘 要： | 狮形岭锡矿赋存于大义山复式花岗岩体内,矿化类型以云英岩脉型为主。通过矿区地质特征的研究,在构造、岩浆岩、蚀变等方面分析矿脉控矿因素。郴州—邵阳NW向深断裂带及"大义山式断裂构造带"形成的次级断裂构成了深断裂控矿—区域性断裂导矿—次级断裂容矿的构造成矿配套体系;岩浆岩,特别是晚期介头单元为矿区成矿母岩,与锡矿形成密切相关,为矿体形成提供成矿物质及热源。

| Abstract: | The Shixingling tin deposit,a greisen mineralization type,is located in the Dayishan granite body. The study is focus on the geological characteristics,ore controlling factors with the analysis of vein struc-ture,magmatite,alteration,etc.Chenzhou-Shaoyang deep fracture zone in NW and＆quot;secondary fracture fault of Dayishan trend tectonic belt＆quot;formed a metallogenic system of which deep fault as ore controll region-al faults as lead ore structure,and the secondary faults as ore bearing structure.The magmatite,especially the advanced medium head unit of the ore-forming mother rock,is closely related to the formation of ore bodies.It provided ore-forming material and heat source as well. |
