Abstract

For the first time used the international advanced level of plasma source, acquired seismic section with accuracy better than three meters even within 1 meter, lay the foundation for scientific research, engineering, shallow resources, geological disaster warning and other research. This paper for the first time identified seven seismic reflection interface of Nansha Quaternary, determine that there is acorrespondence between the seismic sequence in range 500ms to seabed sediment and three phases of sea level change and the glacial, interglacial periods. With a fine typical seismic structure, confirm that Nansha Quaternary is consistent with global sea level change. Fine shallow seismic structure indicates that the geological phenomenon of Nansha is rich, shallow faults are very developed, should pay attention to faulting caused mudslides and secondary geological disasters.
