摘要
双旗山金矿床的矿体主要受断裂构造控制,按控矿断裂构造的形态、产状及其力学性质,将控矿断裂分为四类,即NW向压扭性断裂、NE向扭性断裂、近SN向或NNE向剪切带和NWW向张性或张扭性断裂。受NW向断裂控制的金矿化属片岩+石英脉型金矿化;受近SN向或NNE向剪切带控制的金矿化属蚀变岩型金矿化。
The orebodies of the Shuangqishan gold deposit are mostly controlled by fault structures which are classified into four kinds according to its shape, occurrence and its mechanic feature. They are NW trending shearing compressional fracture, NE trending shearing fracture, near SN or NNE trending shear zone and NWW trending tensional or shearing tensional fracture. The gold mineralization controlled by NW trending fracture belongs to quartz vein type. The gold mineralization controlled lay SN or NNE trending shear zone belongs to altered rock type gold mineralization.
