| 摘 要： | 渤海在新生代经历2次强烈的沉降阶段,海域内各断裂活动对渤海盆地的演化发育产生重要影响.以渤海40°N以南海域单道地震资料为基础,对研究区内断裂活动性进行研究,结果表明:晚更新世(128 ka BP)以来,研究区内断裂活动性很强,以郯庐断裂渤海段最强,其平均垂向活动率大于0.05 mm/a;此期间渤海经历2个构造活跃期,...

| Abstract: | There happened two subsiding moments to Bohai Sea in the Cenozoic.The activity of the faults in this area played an important role in affecting the evolution and development of the Bohai basin.Based on seismic data collected in this area,this paper studied the activity of the faults in the southern part of Bohai Sea since the late Pleistocene.The results show that the fault activity is intensive since the late Pleistocene,of which the activity of Tanlu Fault Zone is the most intensive,with the average rate ... |
