The northeastern section of the fault zone shows increasing interaction with WNW-ESE trending structures within the eastern Kunlun Shan and the Qilian Mountains. The estimated displacement rate decreases along the northern section, suggesting that some of the displacement is transferred onto thrust structures along the south side of the Qaidam Basin. Northeast of the Qilian Mountains, a series of five or more splays of the ATF have been identified, with active slip constrained to the post-Cretaceous to pre middle Miocene time interval.
