摘要
For the purpose of studying the distribution characteristics of Moho and its relation with the tectonic units such as marginal basins, trenchs, island arcs and Cenozoic sedimentary basins in South China Sea and adjacent areas, the authors summarizes the relief, trend, gradient of Moho and crustal nature in the study area by the statistical analysis for the known seismic profiles and 9 profiles planed. Finally, the authors draw the diagram of the trench, island arc and back-arc basin system in the study area. The results of the studies are important to further research of tectonic characteristics, oil and gas prediction, lithosphere and geological and geophysical survey.
