The western-edge fault belt is the most dominating structure element in the west of South China Sea. It runs through the main sedimentary basins from north to south and has the property of strike-slip fault. The western-edge fault belt forms different arrangements of faults because of diverse strike-slipping directions at various geological times. Faults arrangements consist of negative flower structure, two groups en-echelon faults of northeast and northwest strike and double horse-tail shaped structure associations in plane. The main fault of the western-edge fault belt is of single stripe pattern and evident segmentation movement. Faults character of transform belts between north and south stepover zones is the compounding of negative flower structure, listric normal fault and dominoes reversing adjusting normal fault. According to an integrated analysis, the western-edge fault belt of South China Sea is considered as a long-active fault belt, and its strike-slip movement took place from middle Eocene to Quaternary.
