| 摘 要： | 从地质背景、矿床地质、控矿构造分析了夏家店金矿床特征及其形成过程及成矿机理；矿床产于南秦岭陡岭古隆起边缘寒武系-震旦系碳-泥-硅质板岩及白云岩中；控矿构造具有二次韧性剪切变形、二次构造角砾岩化及二次脉体矿化的特征，显示出式样多种、性质多样、形式多变、活动期次与阶段多次叠加的特点；具体阐述了各构造作用阶段与矿化蚀变之间的关系，建立了地层建造-剪切与张裂构造-热液渗流的成矿系统。属于沉积岩系、构造、热液活动3种地质作用叠加改造的卡林型金矿床。

Tectonic and mineralization of Xiajiadian Carlin-type gold deposit in South Qinling,Shaanxi |
| |
| Abstract: | Based on study of geological setting,ore-controlling tectonic,the paper probes into the geological characteristics and metallogenic mechanism of Xiajiadian gold deposit .The deposit occurs in the carbargillite-siliceous rock and ferroan carbonate rock of the Sinian-Cambrian system on the border of the Douling doming paleostructure in South Qinling.The tectonic system is become ore-control leading factor,this is manifold type and shape,varied nature, pulsution of many time of the tectonic activity.By study of relationship of structural analysis and mineralization-alteration has been set up remould metallogenic system of strata control-shear and tension structure-hydrothermal convection.Xiajiadian gold deposit of like Carlin type is subjected to control of manifold control and reform of geological condition. |
