| 摘 要： | 鸭绿江断裂带是郯庐断裂带东侧的一个次级断裂,也是辽宁东部规模较大的断裂带,具有多期活动特点,先后经历了晚印支-早燕山期(T3-J1)左行平移韧性剪切活动、中燕山期(J2-3)早期低角度伸展滑脱和晚期挤压逆冲活动、晚燕山期(K1)至末燕山期(K2)左行正走滑活动、末燕山晚期-喜马拉雅早期(N)右行走滑活动等4个阶段.它控制着侏罗纪、白垩纪岩浆岩、沉积盆地和矿产的分布,也控制着白垩纪中酸性、中基性火山岩喷发.该断裂带为切割地壳硅镁层的深断裂.最大左行平移20 km,最大垂直断距4 km.该断裂带两侧地质构造特征可以对比,对其研究具有重要的指导意义.

| Abstract: | The large-scale Yalujing fault zone,lying in Eastern Liaoning Pr ov ince,is the secondary fault zone of the Tan-Lu fault zone on its east side, wi th multiple activities. The movements underwent four stages, namely, left-late ral shearing in Late Indosinian-Early Yanshanian epoch (T3 - J1) ; low ang le expanding-slipping and compressive reverse thrust in Middle Yanshanian epoc h (J2-3); left-lateral normal strike-slip faulting from Late Yanshanian (K 1) to the end of Yanshanian (K2); and right-lateral strike-lateral strike- slip faulting from the end of Yanshanian (K2) to Early Himalayan epoch (N). The fault zone controls the distribution of the magmatic rocks, sedimentary basins and minerals. It also controls the intermediate-basic and acidic-intermediat e volcanic rocks of Cretaceous. It is a deep fault that cut the sima. The lift- lateral transposition is up to 20 km, with the greatest vertical displacement o f 4 km. The geological and structural characteristics on both sides of the fault zone are comparable, which is significantly important for the research in the r egion. |
