摘要
Due to the large depositional thickness,quick changes of the strata facies and the complexity of tectonic evolution,it is very difficult and controversial to divide and date Cenozoic stratigraphic system in the southern South China Sea(SCS).In this work,all kinds of stratigraphic systems proposed by domestic and overseas scholars were compared and summarized,and the 2Dseismic profiles by seismic reprocessing were interpreted using drilling data of two key wells obtained overseas,and the seismic reflection characteristics about key tectonic revolutionary surfaces were identified and divided.Based on the data of drilling,lithology,depositional environment,tectonic stress system and paleontology,combined with the tectonic events and the results of chronometry from Borneo,the development time about the tectonic surface of mid-Miocene(T 3 seismic interface) was determined.The analysis of this tectonic revolutionary surface showed that the sea-floor spreading of SCS stopped between 15～ 17Ma which corresponded with Nansha Movement in the Southern SCS and with Sabah orogenic event in the northern part of Borneo.
