3. The evolution process under the control of the multigeodynamic force system (including the boundary forces of Eurasia-Pacific-Indian three massive plates around Nansha block, effects of the deep mantle, relative soft layer-sliding planes within Nansha lithosphere block and the earth''s rotational inertial force) can be briefly divided four stages: the late Cretaceous to the early Eocene stage of uprilfing-erosion and shear-extension caused by the oceanwards-eastwards withdrew of Pacific subduction zone and the delamination of proto-subducted slab after the stage of pre-Cretaceous pre-rifting active continentoceanic plate margin. In this stage, the Nansha transcrustal layering-block started to move southeastwards on the Nansha transcrustal layer-sliding plane, meanwhile, the Andu-Bisheng and Liyue-Banyue basement layering-block slid on their upper-crust layer-sliding planes, and Xibu accretion zone was formed. Successively, it entered the stage of the mid-Eocene to early Oligocene, when NW-SE sea-floor spreading occurred in the southwest subbasin owing to the slip-line field initiated by the collision between the Indian and Eurasian plates, Zengmu foreland-basin started to develop in the same time. And in the stage of late Oligocene to early Miocene, near NS simple-shear extension and sea-floor spreading in the central subbasin of eastern South China Sea resulted from the south-southeastwards drawing-force of the mantle-flow.
