Great depth of water and thickness of sediment, high rate of deposition and rich content of organic matter in northeastern South China Sea provide the formation of gas hydrate with the necessary gas supply. Based on the marine geology of northeastern South China Sea or offshore of southwestern Taiwan, multiple-channel seismic profiles and high resolution sub-bottom 3D-topographic images interpreted and analyzed, it is found that there are many normal faults in the deformation front, blind faults in the trench axis and(blind) thrusts in the accretionary wedge, which developed into thrust group that divided into the imbricate thrust sheets.
