Abstract:Based on the analyses of active faults and Global Position System (GPS) data of the eastern Tibet plateau, the paper attempts to discuss the geometry, kinematics and deformation of the active blocks in eastern Tibet plateau. The preliminary conclusions are: (1) The boundaries of the "active" blocks which have actived in Quaternary, especially in Late Pleistocene are associated with the primary boundaries of the tectonic units (those are five suture zones and a deep, lithospheric fault zone between the terraines) , a few were newly formed since late Quaternary Period; (2) The kinematics characteristic of all active blocks induced from the active faults data are as same as one from GPS data, as the boundary, Xianshuihe - Yushu - Mani fault belt is very important for the movement way of the active blocks at the southern the fault belt is different from the ones at the northern side ; (3) Not only does the intensive deformation exist within the boundary zone between two active blocks, but also the deformation has taken place in the active blocks interior since Quaternary Period; (4) Since Late Pleistocene, the kinematics and deformation characteristic of the Tibet plateau crust should be that: when the active blocks moved to NE under the Indian plate compression, the steady blocks (i.e. Xiyu block region, Huabei block region, Nanhua block region) at the front held up the movement of the blocks, meanwhile the adjustment way of the active blocks was thickening crust and the blocks horizontal transfer to the tectonic weaker places, that is, the active blocks at the south of Xianshuihe - Yushu - Mani fault belt rotated clockwise to SE -SSE as an entirety around the Eastern Himalayan Syntaxis, while the blocks in the northern side of the fault belt displaced sinisterly to NWW -W.
