运用基础地质调查和化探方法，对金龙山金矿区成矿带构造、矿区构造、矿脉、矿体及矿石矿物特征进行研究，得出金龙山成矿带脉赋存规律为NE或NW向断裂构造角砾岩型矿化体与近EW向层间剪切带型矿化体交会，主矿脉呈NE向展布，矿脉延深大于延长，控矿构造以主断裂控矿为主、次级断裂控矿为辅。建立了NE向主构造控矿模式：左行走滑构造带在剖面上呈负花状构造，金矿脉及其上部的汞锑矿脉发育在断裂带中，形成断裂构造角砾岩型矿化体，控矿断裂旁侧层间剪切带中形成层间剪切带型金矿化体。锡铜沟-金龙山成矿带分布着4个应变中心，目前仅东坪-两河应变中心未发现任何矿床（仅有铅锌矿点），所以该应变中心将是下一步找矿的远景区。北侧的镇安-龙王沟和锡铜沟-铁厂构造变形带中同时存在强变形带及弱变形域，这2条变形带也是重点成矿区域，可作为成矿远景区。
運用基礎地質調查和化探方法，對金龍山金礦區成礦帶構造、礦區構造、礦脈、礦體及礦石礦物特徵進行研究，得齣金龍山成礦帶脈賦存規律為NE或NW嚮斷裂構造角礫巖型礦化體與近EW嚮層間剪切帶型礦化體交會，主礦脈呈NE嚮展佈，礦脈延深大于延長，控礦構造以主斷裂控礦為主、次級斷裂控礦為輔。建立瞭NE嚮主構造控礦模式：左行走滑構造帶在剖麵上呈負花狀構造，金礦脈及其上部的汞銻礦脈髮育在斷裂帶中，形成斷裂構造角礫巖型礦化體，控礦斷裂徬側層間剪切帶中形成層間剪切帶型金礦化體。錫銅溝-金龍山成礦帶分佈著4箇應變中心，目前僅東坪-兩河應變中心未髮現任何礦床（僅有鉛鋅礦點），所以該應變中心將是下一步找礦的遠景區。北側的鎮安-龍王溝和錫銅溝-鐵廠構造變形帶中同時存在彊變形帶及弱變形域，這2條變形帶也是重點成礦區域，可作為成礦遠景區。

Using the basic geological survey and geochemical method,conducts research of the ore belt structural, mine area structural,ore-veins,ore-body characteristics and ore mineral characteristic,the metallogenic regularity of Jinlongshan metallogenic belt’s ore-veins is NE or NW trending fault breccia mineralized bodies and EW-trending interlaminar shear zone mineralized bodies intersection.The extension of the main ore-veins which distribute to the north east is greater than the extended regularity.And Ore-controlling fracture is based on the main fault based,secondary faults supplement.The NE to main structural metallogenetic model had been set up, and which shows that: Sinistral strike-slip tectonic belt is loss flower structural in the section.Gold veins and its upper mercury-antimony veins developed in the faults and formed the fault breccia mineralized bodies,and also developed in the shear zones beside the faults and formed the interlaminar shear zone mineralized bodies.There are four strain centers in Xitonggou-Jinlongshan metallogenic belt.But only the strain center of Dongping-Lianghe has not fond any deposits.It is the vision area of the next prospecting work.At the same time,there also is a strong deformation zones and weakly deformed domain in Zhenan-Longwanggou and Xitonggou-Tiechang tectonic deformation zones which also are the key mineralization area,and can be used as mineralization prospects.
