摘要: Abstract The Qilian Shan, located in the northeastern Tibetan Plateau, has been continuously extending to foreland since late Cenozoic, resulting deformation of Hexi Corridor Basins. Five terraces Hongshui River are faulted southern Zhangye Basin, a sub-basin Corridor, documenting tectonic history Minle Fault Quaternary. In this study, high precision digital elevation model (DEM) generated by unmanned aerial vehicle (UAV) photogrammetry is used obtain cumulative vertical offset each terrace. And abandonment ages dated AMS 14C dating. results show that produced an almost constant shortening rate 0.95 ± 0.30 mm/a 42.3 ± 0.5 ka, and active throughout Holocene. could represent south margin Basin. Geological geodetic data indicate rates Basin steady 104 10-year timescales. north fault-fold system (NQF) not changed significantly Quaternary may be consistent with 106-year timescale, although further studies needed.
