摘要
分别对东海陆架盆地和冲绳海槽盆地的地质概况、地壳结构、地热场分布及热水活动状况、地震层析成像及其它地球动力学研究做了综合分析 ,研究结果偏重于大陆地壳下的物质向边缘海方向扩张 ,形成边缘海和边缘洋盆的模式 。
As one of the marginal seas of the northwest Pacific,the East China Sea is relatively young and has many distinct traits on its geodynamics.The studies on the aspects of geology,crust structures,distributions of geomagnetic and gravitational fields,heat flow distribution and hydrothermal activities,seismic tomography and other geodynamic methods in the area of the continental shelf of the East China Sea and the Okinawa Trough give something new about the formation and evolution of the East China Sea.Many recent studies of this area in different fields seem to be agreeing with the opinion that the spread of Ryukyu Arc towards the Pacific leads to the formation of the Okinawa Trough,instead of the assumption that the subduction of the ocean plate produces the back arc basin,which has been accepted for a long time.
