Abstract The Xianshuihe (XSH) fault in eastern Tibet is one of the most active faults China, with next large earthquake likely to occur along its SE part, where splits into three parallel branches: Yalahe, Selaha and Zheduotang (ZDT). Precisely quantifying their slip rates at various timescales essential evaluate regional hazard. Here, we expand our previous work on nearby ZDT Moxi (MX) faults, add observations Yalahe newly discovered Mugecuo South zone. Using tectonic‐geomorphology...
Abstract The dearth of quantitative studies Holocene fault slip‐rates makes kinematic modeling crustal deformation across SE Tibet debatable. ∼230 km long, WNW‐striking, dextral Beng Co (BCF) is the most prominent strike‐slip southern Tibet. Using new UAV topographic data and OSL/ 14 C dating geomorphic markers, we measure horizontal offsets ages fluvial terraces/fans lacustrine shorelines at eight sites west east Lake pull‐apart. Along eastern BCF's northern branch, our measurements two...
Abstract More accurate normal fault mapping and more recently constrained extension rates in southern central Tibet allow to better discuss the mechanical processes responsible for distribution of Tibet. First, we show that location rifts south Karakorum‐Jiali zone (KJFZ) does not exactly correspond rigid Indian lower lithosphere flattening below (underthrusting) inferred by P‐waves global tomography, thus suggesting an absence coupling between two processes. Instead, E‐W KJFZ appears...
Abstract The Anninghe-Zemuhe-Xiaojiang fault zone (AZXFZ) is an important boundary on the southeastern margin of Tibetan Plateau, with frequent strong earthquakes. Previous studies have imaged widespread low-velocity zones in this area. However, there are still many disputes connectivity and genesis zones. In study, we obtain Rayleigh wave phase velocity dispersion curves at 4–25-s periods using observations from 378 broadband stations located near AZXFZ. new 3D S-wave model has a lateral...
Abstract Precise studies of Quaternary extension rates across NS‐trending normal faults in southern Tibet are important to understand the recent tectonic evolution high plateau. As one six main, southernmost Tibetan rifts, ∼NS‐trending Peiku Co‐Gyirong rifts and intervening horst (PGR), co‐involve west‐dipping Gyirong fault (GF) east‐dipping Co (PKF). Using unmanned aerial vehicle (UAV) high‐resolution topographic data, 14 C dating lake shorelines, 10 Be cosmogenic exposure alluvial...
Abstract Understanding the onset and episodes of magmatism is essential for comprehending tectonic history, crustal extension, geodynamic processes. However, due to physical constraints, many places have remained unexplored, which makes it difficult understand their geological evolution. Following thorough sedimentary provenance analysis, chronology periods within a drainage area can be revealed through detrital zircon U-Pb dating method. Here, we present ages (n = 1429) obtained from...

Abstract The Xianshuihe fault, located in the southeastern Tibetan Plateau, stands as one of most active faults China. As assessing earthquake hazard relies on access to long‐term paleoseismological archives, this paper seeks optimize interpretation records. We retrieved nine sediment cores from three lakes over a 30 km fault segment. Earthquake‐related deposits were identified through grain‐size analysis, XRF core scanning, and SEM observations thin sections. Age models based short‐lived...
Determining the timing of E-W extension across NS-trending rifts in southern Tibet is key to test mechanical models latest evolution collision between India and Asia. We focus on half largest seven main rifts, Yadong-Gulu rift (YGR), which, despite being numerous studies thanks its easy access, still lacks direct time constraints. Using illite K-Ar ages fault gouge from active Yadong normal YGR, we directly constrain onset at 9 ± 1 Ma. (U-Th)/He dating footwall leucogranite reveals a rapid...
The Pamir Plateau region of the Northwestern Tibetan forms a prominent tectonic salient, separating Tajik and Tarim basins. However, topographic evolution remains elusive, despite key role this played in retreat Paratethys Ocean aridification across Central Asia. Therefore, SW basins are prime locations to decipher geological history Plateau. Here, we present detrital zircon U/Pb apatite fission-track (DAFT) ages from Keliyang section Basin. DAFT show that sediments had three components...
Cenozoic collision between the Indian and Asian continents is generally considered as main driver forming high Tibetan Plateau (TP). However, it remains hotly debated when how relatively flat highly elevated TP was formed. Here, we present combined analyses of apatite fission track (AFT) (U-Th)/He (AHe) 18 granite samples along three steep topographic transects in central part Qiangtang Terrane (QT), TP. The results indicate that AFT ages all are mostly 130 Ma 80 Ma, while AHe range from to...
