基于断裂构造动力学的熊耳山地区沙沟银铅矿床成因分析

Genetic analysis based on dynamics to Shagou silver lead deposit in Xiong'ershan

沙沟银铅矿产于小秦岭熊耳山古老变质岩系中,通过对其矿床地质、主要控矿因素及主要容矿断裂构造特征和动力学特征进行分析,结果发现:沙沟银铅矿床之矿体常成群成带分布,主要产出于NE—NNE向容矿断裂内,属于的受陡倾斜容矿断裂破碎带控制的薄脉型中低温热液型银铅矿床。

Shagou silver lead deposit is located in old metamorphic rocks of Xiong'ershan district of Qinling Mountains.According to analysis to geology,main ore controlling factors,ore bearing fracture tectonic characteristics and dynamic characteristics,the results showed that the ore bodies of the Shagou Ag-Pb deposit are often formed in groups and mainly distributed in the NE-NNE ore bearing fault.The mine belongs to the thin vein type medium low temperature hydrothermal silver lead deposit?which is controlled by the steep inclined ore bearing fault fracture zone.
