摘要
位于辽宁丹东地区的五龙金矿受ＮＥ向剪切系统控制．在剪切带发展演化过程中，于不同阶段形成不同类型的金矿化。在早期韧性剪切带上升剥蚀阶段出现的ＮＥ向脆－韧性线状剪切带，控制同剪切带型金矿；叠加在韧性剪切带之上的ＮＮＥ向一级断裂控制破碎带蚀变岩型金矿的形成和分布；沿ＳＮ向和ＮＷ向的二级断裂构造控制含金石英脉型金矿。
ulong gold deposit is controlled by NE--trending shear system in Dandong, Liaoning Province. The different mineralization types Df gold occur in distinct stages of the shear zone evolution. The NE--trending. brittle--ductile shear zone formed in rising stage of the early ductile shear zone controlled syn--shearing gold deposit. The first--order NNE--trending fault superposed on the ductile shear zone is characterized by the distribution of the gold--alteration rock deposit. The second--order faults of the SN and NW--trending is related to gold--bearing quartz veins.
