Initiation and Long-Term Slip History of the Altyn Tagh Fault |
| |
| Abstract: | New Tertiary piercing points along the eastern and central Altyn Tagh fault, the northern boundary of the Tibetan Plateau, allow construction of the first well-defined time-displacement curve for the fault. Displacement-history analysis indicates: (1) late Oligocene-earliest Miocene inception of the Altyn Tagh fault; (2) 375 ± 25 km of total left-lateral slip on the eastern and central segment of the Altyn Tagh fault; and (3) an average long-term Cenozoic slip rate of approximately 12-16 mm/year. These results demonstrate that Himalayan deformation propagated well into the interior of Asia by early Miocene time and that a significant amount of India-Asia convergence was accommodated by sinistral slip on the Altyn Tagh fault. |
