中文摘要：

根据中国海洋石油研究中心勘探研究院新取得的渤海明化镇组（N1^2-N2）和第四系底部构造的资料，在从黄河口到长兴岛的NE向地带发育近600条断裂，其中NE—NEE走向的有近500条，占断裂总数的83％，一般长5—20km，最长40—50km。这组断裂有少数为NE--NEE向古近纪断裂新活动的产物，其余是新形成的，它们总体组成宽约60km的NE向断裂带，具右旋走滑性质。该断裂带不受古近纪断裂构造控制，属新近纪以来发育的新生断裂带。这一现象证实了以前推断的黄河口一庙西北新生断裂带的存在。

英文摘要：

Based on structural data of the Minghuazhen Formation（ N1^2-N2 ） and base of Quaternary system from Research Center of China Offshore Petroleum Company, there are about 600 faults developed in the region from Yellow River Estuary to the Changxing Island. Among them, nearly 500 faults trend NE-NEE,amounting to 83 percent of the whole fault group. The faults are about 5 - 20km long, and the longest one is 40 - 50km. Some of this set of faults result from reactivation of NE--NEE trending Tertiary faults,and the rest are the newly-generated. They form a NE-striking fault zone about 50km wide with right-lateral strike slip component. This fault zone is not controlled by Tertiary faults; it is a newly generated fault zone during Neogene. It proves the former speculation of the existence of the newly-formed Yellow River Estuary-Northwest Miao fault zone.
