| Abstract: | First Crustal Monitoring and Application Center,CEA,Tianjin 300180Abstarct Two 3D finite element models of China continent are created and the continental deformation under the India-Eurasia collision and basal traction resulting from mantle convection is calculated.And the differential velocity field between the theoretical result and the GPS observation is calculated.The theoretical simulations in middle time scale(0.1 ma)are consistent with that of GPS observation which focuses on the surface movement in the short time scale of 10 years.In the differential velocity field,Tibetan plateau assumes a strong outside extrusive trend,while Altyn Tagh fault which is located in the north margin of Tibetan plateau shows remarkable left-lateral differential movement,Tarim basin and southwest region of China around Burma arc indicate uniform clock-wise rotation,and Zhang-bo fault system in North China assumes left-lateral differential movement.Such character could be generalized that multiple diving forces including India-Eurasia collision and basal traction resulting from mantel convection control constructional movement of China continent,at the same time,large fault systems also influence the movement pattern. |
