摘要

Abstract

Dongsha Island and the adjacent sea area locate at the northern continental margin of the South China Sea (SCS)

and is connected to the east by the Manila Trench. Analyses of seismic stratigraphy and gravity

magnetic and drilling wells data led to the discovery of three post-fault sequences (V

VII). Extensive tectonic uplift

magma activity and erosion occurred in Dongsha Island and the adjacent area

where most of the faults in the northeastern SCS were still active during Pliocene and Quaternary. Two groups of faults trending NEE and NW were developed during Late Cenozoic. We conclude that three important tectonic movements

especially Dongsha movement (4.4–5.2 Ma) and Liuhua movement (1.4–1.89 Ma)

controlled the structural framework in the Dongsha rise; whose deformation in the east is stronger than that in the west and whose stress field variation suggests that the tectonic uplift in the study area contributed to magmato-tectonic events correlated to the main collision phases between the East China and Taiwan 5-3 and 3-0 Ma ago.
