Abstract
We present a preliminary determination of crustal deformation based primarily on GPS measurements we made in Xinjiang from 1995 to 2002,combined with the data of continuous GPS data in Central Asia.The results show that the sites on the southern border of the Tianshan move at(15~19) mm/a to the NNE relative to the stable Eurasia plate.This rate increases to(20.9±0.6) mm/a at Yopurga,our southernmost site in the Tarim basin,located 35km to the southeast of the range front.A preliminary GPS Eurasia-Tarim Basin Euler vector of 36.5°±0.5°N,99.2°±1.1°E,0.525°±0.030°/Ma is determined.
