南海南北共轭张裂陆缘的综合地球物理研究

Based on the new aquired synthetic geophysical profile across the margins of the South China Sea, the lithosphere structure, deformation characteristic and its control factors of the conjugate rifted margins will be studied with gravity, magnetic and seismic data. The focus of study is on the southern margin of the South China Sea and will be compared with the northern margin to understand the asymetric rifting and the time-space change on the crust-lithosphere scale. The study result is expected to provide scientific basis for the ongoing study of the deepsea process and IODP in the South China Sea.

利用南海新采集的穿过南北大陆边缘的综合地球物理测量剖面，采用重力、磁力和地震相结合的综合地球物理手段，研究南海南北共轭大陆边缘岩石圈结构、变形特征及其控制因素，重点以南海南部陆缘研究为主，与北部陆缘已有成果对比，理解在地壳-岩石圈尺度下南海陆缘张裂的不对称性和张裂过程的时-空变化。研究成果可为南海深海过程研究以及即将实施的南海深海钻探计划提供科学依据。
