【摘要】 南海南部最新深地震探测对于南海南北共轭陆缘的对比研究及南海形成演化理论的研究至关重要.以南海深地震探测发展历程和南海南部区域地质地球物理特征为基础,借鉴世界上典型共轭陆缘对比研究的方法,结合2009年新获得的两条海底地震仪测线,指出了南海南部及深海盆深部结构研究的迫切性与重要性,并提出西南次海盆的深部结构、洋盆中海山的速度结构与属性及南北共轭陆缘张裂体系,是今后南海形成演化理论问题的重要突破点.更多还原

【Abstract】 The deep seismic surveys in the southern South China Sea(SCS) are of vital importance for conjugate continental margins and the theory of formation and evolution of SCS.This paper firstly reviews the survey history,then analyzes the geological and geophysical characteristics and finally presents the significance of deep structure research in southern SCS based on comparing the conjugate continental margins with Newfoundland and Iberia.Deep structures of the southwestern sub-basin,velocity structures of sea mountains in the deep basin,and the whole rifting system could make breakthrough for the theory of formation and evolution of the SCS in the future.更多还原
