| 摘 要： | 通过分析阿尔金断裂带西段车尔臣河出山口以西 85°～ 86°E的高精度SPOT卫星影像 ,结合野外考察和年代学研究 ,对阿尔金断裂带西段 3个典型走滑断层的断错地貌进行了研究。在库拉木拉克 ,阿尔金断裂带西段自 (6 0 2± 0 4 7)kaBP以来的左旋滑动速率为 (11 6± 2 6 )mm/a ,自 (15 6 7± 1 19)kaBP以来的左旋滑动速率为 (9 6± 2 6 )mm/a ;阿羌牧场附近 ,自 (2 0 6± 0 16 )kaBP以来的左旋滑动速率为 (12 1± 1 9)mm/a ;达拉库岸萨依附近 ,自 (4 91± 0 39)kaBP以来的左旋滑动速率为(12 2± 3 0 )mm/a。由此得到阿尔金断裂带全新世以来的平均滑动速率约为 (11 4± 2 5 )mm/a。以阿尔金断裂带走向N75°E计算 ,阿尔金断裂带西段左旋走滑所吸收的青藏高原SN向缩短速率为 (3 0±0 6 )mm/a

| Abstract: | As the northern boundary of the Tibet Plateau,the Altun Fault runs more than1500km from Lazhuglung,Tibet Autonomous Region to Kuantanshan,Gansu Province,separating the Tibet Plateau from the Tarim Basin.The fault is one of the longest strike-slip faults in China,and the research of it may pro-vide important information about the formation and evolution processes of the Tibet Plateau. The displacement and slip-rate of the Altun Fault is a topic full of disputation.Because of its signifi-cance to the forma |
