      Abstract
    • Deep crustal structure in the northwest sub-basin contains the key information of the rifting process of the northern continental margin of the South China Sea (SCS). A 386 km-long seismic profile (OBS2006-2) with wide-angle reflective and refractive ocean bottom seismometer (OBS) data was acquired across Xisha block and the Northwest sub-basin (NW sub-basin) of the SCS in NEE direction, which is the only profile hitherto parallel to the expanding ridge of the NW sub-basin. The crustal structure along OBS2006-2 has been obtained by using ray-tracing simulation method (RAYINVR), which yields information on the velocities, tectonics, and geophysical properties. Our velocity structure indicates that sediment thickness increases from Xisha block (about 1-2 km) to NW sub-basin (about 2-3 km). Moho interface changes from typical continent margin of South China (~27 km) to oceanic crust (~12 km). The velocity at the top of upper mantle varies from 7.8 to 8.0 km/s. No high velocity layer and low velocity layer have been identified. Voluminous magmatism in transition zone between Xisha block and NW sub-basin, is possibly related to the initial extending of the NW sub-basin. The part of model in the domain of 220-370 km would be of oceanic crust while the western part in the domain of 0-220 km may be of thinned continental crust. Residual magma may exist under the speading ridge of the NW sub-basin deduced by the anomaly of Pn seismic phase.
