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。
獅形嶺錫礦賦存于大義山複式花崗巖體內，礦化類型以雲英巖脈型為主。通過礦區地質特徵的研究，在構造、巖漿巖、蝕變等方麵分析礦脈控礦因素。郴州-邵暘 NW嚮深斷裂帶及“大義山式斷裂構造帶”形成的次級斷裂構成瞭深斷裂控礦-區域性斷裂導礦-次級斷裂容礦的構造成礦配套體繫；巖漿巖，特彆是晚期介頭單元為礦區成礦母巖，與錫礦形成密切相關，為礦體形成提供成礦物質及熱源。

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"secondary fracture fault of Dayishan trend tectonic belt"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.
