下辽河平原—辽东湾的新构造运动

Neotectonic movements in the Lower Liaohe River Plain and the Liaodong Gulf

通过地质、地貌及地球物理资料分析研究 ,发现下辽河平原—辽东湾的新构造运动的主要特征除了断裂发育、火山活动早期剧烈而晚期衰弱、现代地震活跃以及地壳差异和反差升降运动明显之外 ,还显示了 :( 1 )深大断裂的控制性 ,( 2 )沉降中心的迁移性 ,( 3)构造运动的阶段性和旋回性 .

The data about geology, geomorphology and geophysics are analyzed and summarized in the Lower Liaohe River Plain and the Liaodong Gulf. The main features of neotectonic movements and their expressions in the characteristics of paleogene, neogene and Quaternary stata as well as landforms are pointed out.
