摘要

Based on the multiple-epoch Global Positioning System observations during a period from 1992 to 1999, we document directly a rapid crustal shortening of ~ 20 mm/a across the western Tianshan Mts. (76 E), in contrast to a 4 mm/a convergent rate across the eastern Tianshan Mts. (87 E) and the north-south convergence across the mountain belt descends laterally From west to east. The direction of current crustal movement inferred by GPS sites along the Southern flank of the Tianshan Mts.
