Abstract The deep structure of active reverse faults is generally difficult to constrain from surface observations and may conceal shortening within the hinterland. Here we investigate geometry active, crustal‐scale faulting deformation an unusually extensive set river terraces preserved along Beida River through northwestern Qilian Shan. Two generations fill (T1 T2) are well foreland basin at least 45 km Optically stimulated luminescence 10 Be dating methods indicate that T1 was abandoned...
Abstract At the eastern Qilian Shan mountain front in NE Tibetan Plateau, Minle‐Damaying Fault (MDF), southernmost fault of North Frontal Thrust (NFT) system, has previously been proposed as an inactive structure during Holocene. Here we present a detailed record six strath terraces Xie River that document history active deformation MDF. One optically stimulated luminescence dating sample constrains abandonment highest terrace T 6 at 12.7 ± 1.4 ka. The formation ages lower (T 4 –T 1 ) are...
Abstract The Qilian Shan, located in the northeastern Tibet, is under strong tectonic activity and earthquake motion due to propagation of plateau. At mountain front eastern Tongziba River, southern Zhangye Basin, flows northward successively cuts Minle‐Damaying Fault Yonggu Anticline, two parallel structures within Frontal Thrust system Shan. Here we present a detailed record seven strath terraces this river that documents history active deformation structures. Based on estimated crustal...
How long-term changes in surface topography relate to coseismic uplift is key understanding the creation of high elevations along active mountain fronts, and remains hotly debated. Here we investigate this link by modeling development growth strata folding river terraces above Pishan duplex system southern Tarim Basin. We show that synchronous thrusting two neighboring faults with varying slip rates, associated in-sequence propagation thrust system, required explain presence opposite-dipping...
Abstract Seismogenic faults are commonly composed of a series segments, revealed by geometric barriers and along‐strike gradients in fault activity. At the northeastern margin Tibetan Plateau, Minle‐Damaying Fault (MDF), bounding portion eastern Qilian Shan, illustrates segmented paleoseismic behavior major seismogenic reverse fault. Field surveys, trench excavations, drone‐surveyed topography along MDF reveal scarps with diverse cumulative displacements. Multiple events, timing constrained...
The development of planation surfaces requires stable tectonic and climatic conditions. However, it is difficult to discuss in detail how movement and/or climate change affects erosion, deposition, uplift associated with the development, formation, disintegration surface. This article presents a case study on formation Tangxian surface (TXPS) by establishing magnetostratigraphy one piedmont deposition section related planation, combining depositional sequence overlying TXPS basin sediments....
Abstract Understanding the propagation of shortening, especially interaction shallow and deep structural levels in space time is important to understand accretion process a compressional orogen as well fully earthquake hazards populated foreland basins. Here we combine evidence from geologic maps stream‐terrace surveys construct set retrodeformable cross‐sections western North Qilian Shan foreland. The uplifted, severely tilted Mesozoic older rock units suggest presence both décollements...
Abstract The Shanxi Graben System (SGS) is one of the first‐order Cenozoic tectonic features in North China. Understanding kinematics this system crucial for deciphering mechanism continental rifting and deformation pattern across Although SGS has long been thought to be a right‐lateral, transtensional shear zone, geologic geomorphologic evidence dextral strike‐slip along its internal faults was slim even controversial. Field investigations, interpretations satellite imagery, construction...
Abstract Studying the causative structure, extent, and magnitude of historical earthquakes is essential for regional seismic hazard assessment. There has been some debate in literature regarding epicenter, magnitude, seismogenic source 1673 Tianzhen earthquake, one few documented strong that occurred northern Shanxi Graben, China. The Yanggao‐Tianzhen Fault (YTF) long recognized as a fault; however, previous studies have suggested fault not ruptured at surface several thousand years. In this...
It is commonly assumed a thrust has constant slip and uplifting rate along strike, however, this simplified model cannot always be consistent with field observations. The strike patterns variable offsets rates contain plenty of information about the characteristics faulting behavior its relationship adjacent faults. east Qilian Shan, located at northeastern margin Tibetan Plateau, provides us an excellent opportunity to study in thrust-bounded range area. Besides previously reported N-W...
Faulting and folding of basement rocks together accommodate convergence within continental orogens, forming complex zones intraplate deformation shaped by the fault interaction. Here we use river terraces along Dongda to examine tectonic patterns hinterland foreland eastern North Qilian Shan, a zone crustal shortening located at northeast margin Tibetan Plateau. Five Late Pleistocene-Holocene are displaced three major reverse faults: Minle-Damaying fault, Huangcheng-Ta’erzhuang Fengle from...

Faulting and folding of basement rocks together accommodate convergence within continental orogens. Here we use the river terraces sequences along Dongda as geomorphic tracer to examine deformation patterns at northeastern Qilian Shan. Five terraces, T1 (youngest), T2, T3, T4a T4b (oldest), were identified dated 4.2 ± 0.3 ka, 6.1 0.5 12.4 2.5 16.4 0.2 ka 27.4 respectively. Three major reverse faults, Minle-Damaying fault, Huangcheng-Ta’erzhuang Fengle contribute region....
