Abstract

Abstract

According to the result of paleomagnetism inversed from magnetic anomalies of seamounts in the South China Sea,China between its eastern and southwestern subbasins there is much difference in the movement form and active age.There is a transform fault of NNW-trending with compressive left-slip——"the central fault of the South China Sea Basin" between two subbasins.Combined with analysis and interpretation for the given results of geological and geophysical research,it can be concluded that the South China Sea Basin was developed between the ancient South China Sea and the southern edge of South China terrain.The development of the South China Sea can be divided into four stages as follows:Stage Ⅰ,in Eocene the ancient South China Sea was split into two parts with the formation of its fault;Stage Ⅱ,in Oligocene the eastern subbasin began to develop with rupture;Stage Ⅲ,in Miocene the southwestern subbasin began to develop with rift;Stage Ⅳ,the South China Sea revolved and the ancient South China Sea closed.
