| 摘 要： | 郯庐断裂带自南而北穿越渤海东部,自中生代中期至新生代中期表现裂谷发育特征。裂谷发育经历两个旋回,各旋回的裂谷发育演化、盆地分布格局,沉积相带,沉积补偿速度等均受断裂带的断裂活动的强烈控制。

| Abstract: | The Tanlu fault zone, which is situated in the east of China, passes the Laizhou Bay and the east of the Bohai Bay and poms with the Xialiaohe Fault Zone in the Liaodong Bay. It displays the developmental character of rift from the middle Mesozoic to the middle Cenozoic. During the Mesozoic, the subsidence in the middle of the Bohai Bay was still rising and eventually formed a unitive rise in the east-west direction with the Shaleitian Rise on the west. The rise extended in the north to the Liaodong Bay and formed an entity with the Xialiaohe Fault Zone, i. e., the Liaodong Bay-Xialiaohe Rift. In the south, the rise extended to the Laizhou Bay and formed another entity with the Yishu Fault Zone, i.e., the Yishu-Laizhou Bay Rift Being seperated by the rise, the two rifts-one in the south and another in the north-had their individual developmental processes.The development of the rifts experienced two cycles: the Middle Mesozoic(J-K) cycle and the Middle Cenozoic (Eocene-Miocene) cycle The evolution of the rifts in the cycles, the distributive frame of the basins, the sedimentary facies zones and the sedimentary velocity of compensation were all severly controlled by the fault activity of the Tanlu Fault Zone. |
