摘    要:根据最新单道地震剖面及解释成果,分析了东海陆架盆地北部新构造运动特征。研究表明:研究区新构造期差异升降运动明显,从中新世到第四纪,沉降中心自西向东迁移;研究区活动断裂以NE—NNE和近EW向为主,新构造期的活动性自西向东逐渐变新;研究区新构造期岩浆活动频繁,多沿断裂分布,大致可划分为3期,平面上自西向东逐渐变新,且侵入活动逐渐减弱,喷发活动逐渐增强。

关 键 词:新构造运动  升降运动  断裂活动  岩浆活动  东海陆架盆地

Abstract:The newly acquired single-channel seismic and logging data reveal that the neotectonic movement is intensive in the northern East China Sea Shelf Basin.The main types of the neotectonic movement include vertical movement,faulting and magmatic activities.The research found that the depocenter of the Northern East China Sea Shelf Basin has shifted from west to east since Miocene.NE-NNE-striking and EW-striking faults are the main active faults.The faults are getting younger from west to east.Magmatic activiti...
Keywords:neotectonic movement  vertical movement  faulting  magmatic activity  East China Sea Shelf Basin
