| 中文摘要: |
| 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—密山断裂大规模左行平移有关;NE向敦化—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组断裂成为本区最主要的容矿构造。 |
| 英文摘要: |
| 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. |
