Abstract

Abstract

Opening mechanism of marginal basins is one of the fundamental issues of earth science. Based on integrated geological interpretations on deep-reflection seismic and drilling data in the South China Sea (SCS), this study analyzes the deep crustal structure and deformational patterns, the results show: (1) The extension and breakup process of the SCS was ununiform and highly variable, i.e. the continental margin experienced depth-dependent stretching dominated by detachment system, and the breakup process was "a magma-rich" type in the middle-east, but a "magma-poor" one in the west. (2) The spreading process of the SCS was unbalanced and asymmetric, featured with two episodic southward ridge jumps, as well as multiple changes of spreading orientation, resulting in the asymmetric post-spreading magmatism and inhomogeneous lithospheric structure. Base on above-mentioned research, we propose an opening model for tectonic-restricted marginal basins dominated by the West Pacific subduction, which is featured with highly variable continental rifting and ununiform seafloor spreading. The model can enrich the theory of continental margin dynamics.
