摘　　要：海洋磁异常探测技术在海底科学前沿研究中一直发挥着巨大作用,对研究海底地壳结构、板块构造运动以及地球内部动力学过程等具有重要意义。近年来,随着人们对深海构造问题的日益重视,海底磁异常探测技术作为揭示海底构造的强有力手段,受到越来越多的关注。本文将综述近十年来国内外关于海洋磁异常研究的前沿成果,深入讨论大洋盆地演化过程、被动大陆边缘的构造演化、洋壳俯冲过程、洋中脊增生过程以及大洋微板块的形成过程和机制等动力学问题,最后提出该领域存在的问题和今后的发展方向。The detection technology of marine magnetic anomaly has been playing a key role in the frontier studies of submarine sciences,which is of great significance for investigation of the ocean crustal structures,plate tectonic and internal dynamic process of the Earth.Recently,with the increasing emphasis of deep-sea structures,as one of the important techniques to investigate the seabed structures,the detection technology of seafloor magnetic anomaly received more and more concern.In this paper,we review the international frontier development of marine magnetic anomaly researches on seabed structures in the past 10 years,and discuss its dynamic significances including the fined ocean basin evolution,the tectonic evolution of the passive continental margins,the oceanic crust subduction processes,the detailed mid-ocean ridge accretion processes,and the formation process and mechanism of the microplate.Finally,we will raise several important questions and propose future perspectives.
