【摘要】 通过中国东南大陆边缘至菲律宾海域太平洋间过渡带人工地震测深和天然地震面波层析成像的构造解析,发现大陆至大洋间的过渡带岩石圈存在不同的结构样式和动力学型式,结合地质学、构造地质学、地球化学和地球物理学其他标志的综合研究,建立起中国东南大陆边缘带岩石圈3种结构—动力学型式:盆岭结构—伸展动力学型式(南海北部式)、弧陆楔状结构—碰撞楔入动力学型式(台湾式)和沟弧盆结构—俯冲动力学型式(东海式)。在论述中国东南大陆边缘带岩石圈3种三维结构特征的基础上,探讨了该区岩石圈3种基本动力学型式及其地质意义。更多还原

【Abstract】 Based on the tectonic analyses of both the man-made seismic sounding and the tomography for the 1°×1°natural seismic surface wave in the zone, various structural styles and dynamic patterns have been found in lithosphere of the transition zone between the Chinese Southeast Continental Margin and the Philippine Sea. On the basis of a comprehensive study on the geological, geochemical, and geophysical criteria, three lithospheric structure-dynamic types are developed: ① basin-range structure-extensional dynamic type (the northern South China Sea type); ② arc-continent wedge structure-collision-wedging dynamic type (the Taiwan type); and ③ trench-arc-basin structure-underthrusting dynamic type (the East China Sea type).更多还原
