    Li Yuhan, PhD student in the Deep Geophysical Group of the Key Laboratory of Marginal Sea and Ocean Geology ( OMG ), South China Sea Institute of Oceanology, Chinese Academy of Sciences , Huang Haibo, Associate Researcher, and Researcher Qiu Xuelin, in collaboration with Ingo Grevemeyer , Professor of the Helmholtz Center for Marine Research ( Geoma ), Germany Through active source submarine seismograph ( OBS ) detection and deep crustal structure simulation, important progress has been made in the study of the extension and submarine expansion process of the Zhongsha block .


    At the passive continental margin, the continental crust undergoes successive processes of rifting, thinning, rupture, and seafloor expansion under extensional forces.


    In order to reveal the extension and deformation process of the middle segment of the South China Sea, the researchers collected an OBS wide-angle seismic survey line about 400 kilometers long, passing through the Zhongsha block and adjacent basins from north to south, and obtained P waves through forward and inverse simulations.


    The study revealed the influence of the two oceanic ridge transitions in the South China Sea on the Zhongsha block, as well as the control of the pre-existing crustal strength of the Zhongsha block on the extension process and rupture position; redefining the north-south ocean-land boundary of the Zhongsha block ; And discussed the extensional deformation characteristics of the continental margin of the South China Sea, the structure of the ocean-continent transition zone, and the overall changes of magma supply at different stages of submarine expansion


    The data used in this study was collected by the South China Sea Geophysical Shared Voyage Project of the National Foundation of China on board the "Experiment 2 " scientific research ship of the South China Sea Institute of Oceanology, Chinese Academy of Sciences , and was obtained from the National Natural Science Foundation of China, and Guangdong Laboratory of Southern Ocean Science and Engineering (Guangzhou) ) The talent team introduces major special projects, the Guangdong Natural Science Foundation research team project and the China Scholarship Council and other projects and institutions jointly funded
