| 摘 要： | 本文主要根据东海陆架盆地和周边的地质、地球物理资料,分析盆地的基底岩性特征、结构特征。认为东海陆架盆地的基底除元古界片麻岩外,还分布有一定范围的中生界及古生界。基底构造特征是纵向上多层次,横向上不均一,南北有别,东西分带。构造演化上经历了张、合、压、扭等复杂过程。

| Abstract: | The East China Sea Shelf Basin is located on the active continental margin of the West Pacific. We know little about the tectonics and evolution of the basement. In this paper, the author advances some ideas based on recent available geological and geophysical data from the basin and its adjacent region in order to foster more discussions on those problems. The pre-Kz basement of the basin is composed of not only Proterozoic gneiss but Meso/oic as well. The basement in the north block is different in tectonic framework from the south one. The tectonic evolution of the basement, the formation and evolution of the basin are controlled by the interaction of the Eurasian plate, Pacific plate and the Tethys. The development of the basin experienced many tectonic stages during Cenozoic. It is tectonically characterized by zonation from west to east and blocks from north to south. |
