东濮凹陷新生代断裂特征分析

Characteristic Analysis of Cenozoic Faults in Dongpu Depression

为了研究东濮凹陷新生代断裂系统的发育特征,通过对凹陷内不同区段地震剖面的解释,根据断层活动速率分析了东濮凹陷新生代断裂的活动特征及其强度,并对凹陷内不同部位的断层特征进行了对比分析。结果显示,东濮凹陷不同区段的断层发育特征既有一定的相似性,又有一定的差异性。断裂发育受到欧亚构造域和滨太平洋构造域的共同影响,同时在各区段受到的影响又有所差异。

in order to study development characteristics of Cenozoic faults in Dongpu depression, through explana？tion of seismic profiles in different sections, according to activity rates of fault activities, activity characteristics and strength of Dongpu depression in Cenozoic faults have been analyzed, and the characteristics and intension of the faults in different regions have been compared and analyzed in Dongpu depression. As showed by the results, devel？opment characteristics of faults in different regions have some similarities and differences. The faults evolution is in？fluenced by both the Eurasian tectonic system and the Pacific tectonic system. Meanwhile, the influence is different in different regions.
