Abstract

Abstract

The western-edge fault zone of the South China Sea is divided into the southern and northern parts about at 8°N.The main fault of the western-edge fault zone is originated from the Mesozoic basement fault, continuously developed into the Cenozoic, and has dominated the growth of Cenozoic basins nearby it.The non-magnetic, high-density igneous rocks in the fault zone belong to granite intrusion of one period among the Indosinian or Yanshanian Ⅰ, Ⅳ and Ⅴ phases, which is most possibly at the end of the Yanshanian.The main fault of the western-edge fault zone extends through the middle of the Wan'an Basin, and its right-lateral strike-slip activities have induced the marginal depressing and rifting at the east of the Wan'an Basin.
