Based on technical processing of high-resolution SPOT images and aerophotos, detailed mapping of offset landforms in combination with field examination and displacement measurement, and dating of offset geomorphic surfaces by using carbon fourteen (14C), cosmogenic nuclides (10Be 26Al) and thermoluminescence methods, the Holocene sinistral slip rates on different segments of the Altyn Tagh Fault are obtained. The slip rates reach 17.5 mm/a on the central and western segments west of Aksay Town, 11 mm/a on the Subei—Shibaocheng segment, 4.8 mm/a on the Sulehe segment and only 2.2 mm/a on the Kuantanshan segment, a easternmost segment of the ATF. The sudden change points for loss of sinistral slip rates are located at the Subei, Shibaocheng and Sulehe triple junctions where NW-trending active thrust faults splay from the ATF and propagate southeastward.
