摘　　要：营口—潍坊断裂带是郯庐断裂带穿过渤海的部分,在古近纪对渤海湾盆地构造的发育起到重要控制作用,新近纪以来构造活动仍相当强烈。根据获得的部分最新资料及已有研究成果,对该断裂带的新构造和新构造活动进行了较系统的研究。营口—潍坊断裂带的新构造变形主要表现为其先存的古近系断裂复活,在上覆新近系馆陶组和明化镇组及第四系中形成断裂和褶曲,新构造以断裂极其发育为特征。营口—潍坊断裂带沿线新构造发育具继承性和新生性,断裂带新构造变形和新构造活动具有分段性。分析了各段的构造特点和活动性质,并将新构造期分出6个主要的构造活动幕。The Yingkou-Weifang fault zone is the part of the Tan-Lu fault zone across the Bohai Sea,and it controlled the development of Bohai Bay Basin during the Paleogene. Since the Neogene, its activities have been still strong. Based on some new data from the Exploration Institute of CNOOC Research Center and the early studies, the neotectonics and its activities of the fault zone were studied,the results showed that the reactivity of the Paleogene System faults （old faults） in Yingkou Weifang fault zone had generated minor faults and folds in the overlying Guantao Formation, Minghuazhen Formation and Qutanary System. The neotectonics were characterized by many faults. The generation and deformation of the newly-generated faults and reactive old faults showed the succession and segmentation of the neotectonics. The structural characteristics and activity of the fault zone in the different segments were analyzed. Six activity episodes of neotectonics of the fault zone were determined.
