By analyzing and interpreting the newly acquired seismic profile supported by the national 973 Program and synthesizing the data with other geologic & geographic information, we draw conclusions as follows. a) Two seismic reflections located at the northeast South China Sea (SCS) slope and the Hengchun ridge are the Bottom Simulated Reflections (BSRs). Yet, the genesis and process of the gas hydrate in these two areas are different because of different regional tectonics and geological environments; b) The genesis of gas hydrate located at the northeast SCS slope area is related to the broadly existing fracture zones, slumping tectosomes, and the distinctive shielding environment of pressure masking field formed by them. But the genesis of the gas hydrate at the Hengchun ridge is associated with the thrust nappe structures and accretionary wedges formed along the Manila subduction zone and the related sub-floor fluid channel system built by them; c) Since the analogous geologic bodies are broadly distributed at slope areas around SCS and the temperature-press environment is very suitable to the formation and conservation of the gas hydrate, we suggest that much more of this resource should be stored in these areas.Journal
