谢家沟金矿床是一个新发现的矿床。在讨论成矿地质背景基础上,分析了矿床地质特征及其成因。认为谢家沟金矿床是同韧性剪切带蚀变岩型金矿床,焦家断裂带与招平断裂带的差异性构造运动为成矿提供了剪切应力场背景,成矿物质来自地壳和地幔;矿区划分5套构造系统:成矿期的韧性剪切带系统、近东西向的平移断裂系统、北东—南西向拉张应力背景下的构造系统、北东或近南北向的硫铁矿期断裂构造系统、北东向压扭性断裂系统;从剪切蚀变岩带的中心往两侧,岩石蚀变和含矿性具有明显的分带现象。
Xiejiagou gold deposit is a newly discovered deposit. On the basis of discussing the metallogenic geological background, the geological characteristics of the deposit and its genesis are analyzed. It is considered that the Xiejiagou gold deposit is a ductile shear zone altered rock type gold deposit. The differential tectonic movement of the Jiaojia fault zone and the Zhaoping fault zone provides a background of shear stress field for metallogenesis. The ore-forming materials come from crust and Mantle; the mining area is divided into five sets of tectonic systems: the ductile shear zone system during mineralization, the trans-east-west transgranular fracture system, the structural system under the NE-SW tensile stress, the north-east or near-north- And the northeastern crushed fracture system. From the center of the shear-altered rock zone to both sides, the rock alteration and ore-bearing are obviously zonated.
