The development of continental rifting and seafloor spreading can be predominated by magmatic upwelling (magma-rich) or tectonic stretching (magma-poor). Located in the terminal portion of propagating seafloor spreading of the South China Sea (SCS), the southwestern mid-ridge of the southwest sub-basin (SWSB) of the SCS was found with much thin crust and numerous faulted blocks coupling with magma-poor continental margins along its flanks. Therefore, the southwestern part of the SWSB is most likely to be a tectonic-dominated basin. To justify the hypothesis with further evidence, we investigated the nature of seamounts on the southwestern mid-ridge of the SWSB which may inherit seafloor spreading.
