红河断裂带对南海西部盆地成盆过程影响机制实验研究
Red River Fault Zone affected the formation of basins in the western South China Sea:An experimental study
摘要
Abstract
The strike-slip movement of the Red River Fault Zone(RRFZ)affected the formation of the basin in the western part of the South China Sea(SCS)to a certain degree.To characterize the tectonic features of the RRFZ during the uplift interval of the Tibetan Plateau and analyze the relationship between the strike-slip in RRFZ and the basins,especially Yinggehai Basin and Zhongjiannan Basin in the western SCS,sandbox analogue modelling experiments were performed in the context of the India-Eurasia collision.Results indicate that the prototypes of the two basins are controlled by the NW-oriented shear stresses generated by the strike-slip movement of the RRFZ,and the SN-oriented tensional stresses with the SCS opening up and the basin sizes expanding.During the early formation stage of the two basins,the displacement due to the strike-slipping was absorbed by the boundary faults and internal faults of the basins,thus controlling the evolution of the basins during the stage from 35 to 23 Ma.关键词
