摘要
通过对渤海海域的地震资料及地质资料进行综合分析,认为郯庐断裂带在该地区的宽度为50 km,并分为东支和西支。以张家口—蓬莱断裂为界,渤海海域的郯庐断裂带分为南段和北段,南段东、西两支断裂的走滑特征非常明显;北段的东支走滑特征明显,而西支走滑特征不明显。古近纪,北段东支和西支都具有走滑运动,但是由于张家口—蓬莱断裂左旋切割,导致西支走滑受阻而被废弃,因此走滑运动主要集中在东支。
In the Cenozoic,the intense strike-slip movement and complex evolvement of Tan-Lu fault zone in Bohai Sea controlled the basin evolution and hydrocarbon accumulation.Through a comprehensive analysis of the seismic data and geological data in Bohai Sea,the Tan-Lu fault zone in the region with a width of 50km,is divided into the East Branch and West Branch.Tan-Lu fault zone is divided into the southern section and the northern section by Zhangjiakou-Penglai fault.East Branch fault and West Branch fault of the southern section have very obvious strike-slip characteristics and East branch of the northern section has very obvious strike-slip characteristics,but the West branch has not.In the Paleogene,the East Branch and West Branch of the northern section were strike-slip movement,but late cutting of Zhangjiakou-Penglai fault,resulting in West Branch strike-slip fault was blocked and abandoned,so the main strike-slip movement was on the East branch in the Neogene and the Quaternary.
