济阳坳陷东西部构造单元中—新生代断裂特征对比及其控制因素

为了查清济阳坳陷中一新生代不同构造阶段断裂的发育特征，对穿过断裂的地震剖面进行了详细解释分析，采用断层活动速率定量研究了济阳坳陷惠民凹陷和沾化凹陷中-新生代断层的活动性，在此基础上对济阳坳陷东西部构造单元断裂发育特征进行了对比。结果表明，济阳坳陷东西部构造单元中-新生代断裂发育既有一定的相似性，又有一定的差异性。断裂发育受控于欧亚构造域的西伯利亚板块、扬子板块与华北板块的挤压拼接和滨太平洋构造域及其郯庐断裂带和沧东-兰聊断裂带的活动，东部构造单元受郯庐断裂影响较大，西部构造单元受沧东-兰聊断层的影响较大。

Characteristic contrast of Mesozoic and Cenozoic faults of eastern and western structure units in Jiyang Depression and its controlling factors

In order to find out the development characteristics of Mesozoic and Cenozoic faults at various tectonic stages in Jiyang Depression,the seismic sections across the faults are analyzed in detail.The fault activity velocity parameters are applied to quantitative research on the Mesozoic and Cenozoic faults activity in Huimin and Zhanhua Sag in Jiyang Depression.Based on this,the development characteristics of the faults in eastern and western tectonic units in Jiyang Depression are compared.The results show that there are resemblance and difference between them.The faults evolution is controlled by the extrusion and assembly among Siberian Plate,Yangtse Plate and North China Plate in Eurasian tectonic system and by the activity of Peri Pacific tectonic sytem as well as Tanlu and Cangdong-Lanliao fault zones.The eastern tectonic units are mainly influenced by Tanlu fault zone,and the western ones are mainly affected by Cangdong-Lanliao fault zone.
