全球定位系统(GPS)揭示的中国大陆现今运动场清晰地表现出了以活动地块 为单元的分块运动特征,不同的活动地块具有不同的运动和变形方式.GPS观测到的阿 尔金断裂的左旋走滑速率仅(5.l± 2.5)mm/a,龙门山断裂的挤压缩短速率为(6.7± 3.0) mm/a,华南地块相对于欧亚大陆向东的运动速率是 11~14mm/a,这些结果均不支持青 藏高原北部沿主要走滑断裂向东大规模挤出的假说.中国大陆以活动地块为单元的现 今构造变形可能与大陆岩石圈的结构和性质有关,上地壳以脆性变形为主,下地壳和 上地幔以粘塑性的流变为特征,从底部驱动着上覆脆性地块的整体运动.
Global Positioning System (GPS) revealed that the current stadium in Mainland China clearly shows the characteristics of the block movement with active plots as a unit, and the different active plots have different modes of movement and deformation. The left-lateral slip rate of the Altyn Tagh fault measured by GPS was only (5.1 ± 2.5) mm / a and that of the Longmenshan fault was (6.7 ± 3.0) mm / a, The velocity of the block to the east of Eurasia is 11 ~ 14mm / a. These results do not support the hypothesis that the main strike-slip faults in the north of the Qinghai-Xizang Plateau are squeezed eastwards to the east. The current tectonic deformation in China with active massif as a unit may be related to the structure and properties of continental lithosphere. The upper crust is dominated by brittle deformation and the lower crust and upper mantle are characterized by viscoplastic rheology. Cover brittle block of the overall movement.
