摘要

///This paper selects 17 balanced cross-sections from principal Sags in the East China Sea shelf basin. The amount of extensional and compressive ratios from principal sags in Cenozoic have been obtained by means of the technique of balanced cross-sections. Extensional and compressive ratios analyzing showed that the tectonic evolution jumped from west to east in the East China Sea shelf basin. The center of rifting expansion was in the western zone from Late Cretaceous to Late Paleocene，which jumped to eastern zone in the Eocene and to the Okinawa trough basin in the Pliocene. The north of the western zone reversed in the Middle and Late Paleocene，and Xihu sag of eastern zone reversed in Miocene. The difference of the east depression belt and the west depression belt in structural evolution proved that the East China Sea shelf basin is east and west sub-zone. The difference of Changjiang depression in the north of the west depression belt and Diaobei depression in the south in structural evolution and the difference of Xihu sag in the north of the east depression belt and Taibei depression in the south in structural evolution proved that the East China Sea shelf basin is north and south sub-zone.
