英文摘要	GPS measurements from sites within the Tibetan Plateau show not only east-southeast-west-northwest extension but also, more importantly, horizontal dilation throughout the interior of the plateau. Assuming conservation of volume, vertical (thinning) strain rates equal horizontal dilation rates, and they, 8.90.8nanostraina(-1) and 7.41.2nanostraina(-1) in northern and southern Tibet, and 12.03.2nanostraina(-1) in its southwestern part, suggest no measureable difference. Principal extensional strain rates also are similar in magnitude and orientation. If crustal thinning began at 10-15Ma and the current rates of horizontal dilation applied both to the entire crust and to that period, the crust should have thinned by 5.5-8.5km. If isostatic equilibrium applied, the mean elevation of the plateau would have dropped similar to 1km. The similar rates for northern, southern, and southwestern Tibet suggest that the processes dictating crustal extension, normal faulting, and crustal thinning in the three regions differ little from one another.; Natural Science Foundation of China [41304035, 41090294]; Institute of Earthquake Science, China Earthquake Administration [2014IESLZ05]; U.S. National Science Foundation [EAR 1211378, 1246925]; China Scholarship Council (CSC) [CSC 201304190034]; SCI(E); EI; ARTICLE; molnar@colorado.edu; 13; 5227-5235; 42
