| 摘 要： | 横切潍北-莱州湾凹陷郯庐断裂带的地震反射剖面和断裂带内的凹陷断层、沉积相和油气特征，直接或间接显示了郯庐断裂带的延伸、运动性质和活动时限。郯庐断裂带在海域和陆上的几何形态及其组合基本一致，根据切过断裂带的剖面和平面上断层的组合特征，判断其为兼具垂直位移的走滑运动断层系。走滑断裂带的活动控制着凹陷内同构造沉积以及构造样式，表明郯庐断裂带的活动时限具分段性，相当于渤海湾盆地孔店组(E1?2k)-沙四段(E2?3s4)沉积期(古新世-早始新世)-孔店组-沙二段(E2?3s2)沉积期(古新世-始新世)-孔店组-沙一段(E2?3s1)(古新世-渐新世)沉积时期，走滑拉分活动由南向北迁移； 活动方式也由古新世-早始新世的左旋走滑活动，被早始新世之后的右旋走滑活动所替代。

| Abstract: | The Laizhouwan transitional zone of the Tancheng?Lujiang Fault lies between the north of Weifang and the south of the Bohai Bay. The date from seismic profiles which crosscut the Tan?Lu Fault Zone and the characteristics of sedimentary and hydrocarbon in this zone directly/indirectly indicate the extending，kinematics property，and the activity time limit. The Tan?Lu Fault Zone has similar characteristics of geometry shape and geometry array in land area just as it appears in sea area. It can be inferred that Tan?Lu Fault Zone is a faulting system with vertical displacement. Syntectonic deposits controlled by the movement of strike?slip fault zone show a sectional feature of the activity time limit of Tan?Lu Fault Zone. From south to north，it equals to E1?2k deposition to the E2?3s4(Paleocene to Early Eocene)，E1?2k deposition to the E2?3s2(Paleocene to Eocene)，E1?2k deposition to the E2?3s1(Paleocene to Oligocene)in Bohai Bay Basin. The direction of the strike?slip pull?parting migrated from south to north. The fault zone experienced sinistral strike?slip movement from Paleocene to Early Eocene，after Early Eocene，the strike?slip direction is instead of right?lateral strike?slip movement. |
