SIMULATING OF SUBSIDENCE HISTORY AND ANALYSIS OF TECTONIC EVOLUTIONARY CHARACTERISTICS OF LIYUE BASIN IN SOUTH CHINA SEA

In this paper the subsidence history of Liyue Basin was simulated and the changes in tectonic subsidence was analyzed. The results show that the episodic change in tectonic subsidence was closely related with basin evolution, and the three stages of tectonic subsidence correspond well to the three structure layers and the three stages of basin development. Additionally, the inherent relation of tectonic activity and tectonic subsidence with the structural characteristics, basin evolution, sedimentary characteristics was discussed, and it was found that the regional structural activity controls the sediment development.
