| 摘 要： | 夹皮沟金矿受夹皮沟断裂的一系列次级脆性构造控制，按构造性质可划分为NW向、NE—NEE向、近SN向3种控矿构造类型。其中NW向构造显示左行剪切特征，NE—NEE向构造显示右行剪切特征，近SN向构造显示压性特征。经研究提出区内控矿断裂的形成与中生代敦化一密山断裂大规模左行平移有关；NE向敦化一密山断裂与次级平行分布的两江断裂左行平移，使早期形成的夹皮沟压性断裂显示左行压扭特征，诱导应力场派生出一系列NW向、NE—NEE向的剪切断裂，以及近SN向的压性断裂。这3组断裂成为本区员主要的容矿构造。

| Abstract: | Jiapigou gold deposits is controlled by a series of secondary brittle structure of Jiapigou faults, including NW-left handed shearing faults, NE-NEE-right-handed shearing faults and SN-extending compression faults. Moreover, the author points out that, their mechanism is related to the Mesozoic large scale sinistral slip movemert of Dunhua-Mishan fracture zone. The sinistral slip movement of the NE-trending Dunhua-Mishan fracture zone and its secondary fault-Liangjiang fracture zone led to sinistral comprssion-shearing of the already existed Jiapigou fault zone. The induced stress field lead to the formation of a series secondary NW-, NE-NEE shear and SN-extending compression faults, which are the main ore bearing structures in this area. |
