GPS Observation and Study on Recent Crustal Movement in the Northeastern Area of Pamir,Xinjiang
摘要
Abstract
Calculation of repeated observation data at the densified GPS monitoring network in northeastern area of Pamir together with data from IGS stations in the periphery of the area yielded the movement rate of more than 40 GPS station sites in the area, and, hence, the recent crustal deformation rate pattern and time series of fiducial GPS stations in the area were obtained. The result indicates that the principal movement direction of the GPS station sites is NNW, basically diagonal to the strike of Tianshan fold belt, i.e. a normal compression occurs in the Tianshan region. The movement pattern near Jiashi and its southwestern zone is some different from that of station sites in their surrounding areas, indicating a certain relation of tectonic deformation in Jiashi area to seismic activity during last years. The movement rate of station sites in the periphery of Tarim basin less varies and its direction is basically consistent.It indicates less or basically no deformation within Tarim basin.关键词
