| Abstract: | On the basis of the GPS observations during 10 years,the variations of the baselines between adjacent GPS continuous sites in the Qinghai-Tibet block and the surrounding areas are calculated,and then the activities of large-scale crustal blocks and tectonic zones are studied on the basis of obtained tendency and non-linear variations.The NW ward baseline in the western part of the Qinghai-Tibet block shows a variation of extension and the crust displays a tensile change in the direction.The NE ward baseline... |
