The geometry and evolution of fluvial systems are thought to be related surface uplift. In eastern Tibet, rivers exhibit peculiar drainage patterns but how these were established their connection with the plateau uplift still under debate. Here, we use detrital zircon U-Pb dating, bedrock (U-Th)/He thermochronometry, topographic analysis numerical modeling explore paleo-drainage pattern Dadu Anning Rivers, Tibet. Our data indicate that Pliocene sources sediments River different from modern...
The Namche Barwa syntaxis in the eastern Himalaya is rapidly evolving terms of its tectonics and topography. Here we constrain exhumation history Yigong River to immediate north across different time scales using a multidisciplinary approach. Our new thermochronometric data reveal an acceleration rates since 2 Ma downstream Yigong. Cosmogenic nuclides thermoluminescence thermochronometry analyses confirm persistent rapid lower over Quaternary with further increased last 100 ka. Together...
A new thermochronological study of the basement rocks central North Island, New Zealand, records thermal and exhumation histories related to two subduction cycles since latest Jurassic. The comprises metasedimentary terranes accreted onto eastern Gondwana during Mesozoic subduction. Since Oligocene, these have been located on hanging wall Hikurangi margin, overriding Pacific Plate. Results zircon fission track (121–264 Ma) analysis yield detrital or slightly reset ages; apatite (19.8–122...
Abstract. Thermochronometry provides one of few methods to quantify rock exhumation rate and history, including potential changes in rate. Thermochronometric ages can resolve rates, accelerations, complex histories by exploiting different closure temperatures path lengths using data distributed elevation. We investigate how the resolution an history is determined distribution their through error analysis problem. define sources error, defined terms resolution, model methodological bias...
Abstract It is widely accepted that tectonics generally enhances river incision. However, why rivers have not incised further into orogenic plateaus to destroy terrains over long-time scales remains ambiguous. Here we hypothesize the diverse nature of regional could impeded erosion, taking Yarlung River in Tibetan Plateau as a case. We constrain incision history and effect tectonic rift on fluvial by low-temperature thermochronology. Results show focused cooling near rift, but markedly...
Abstract The Cenozoic history of the Tibetan Plateau topography is critical for understanding evolution Indian‐Eurasian collision, climate, and biodiversity. However, long‐term growth landscape remain ambiguous, it remains unclear if plateau uplift occurred soon after India‐Asia collision in Paleogene (∼50–25 Ma) or later Neogene (∼20–5 Ma). Here, we reproduce southeastern using a 2D model, which simultaneously solves fluvial erosion sediment transport processes drainage basins Three Rivers...
Abstract Faulting and folding on the margins of intermontane basins play important roles in accommodating Cenozoic deformation Tian Shan, an intracontinental orogen central Asia. In eastern southern margin elongated Kumysh Basin is bounded by a NE dipping thrust fault, Fault. We report first investigation slip rate this which constrained at two sites profiling faulted topography dating abandoned alluvial fan surfaces. obtained topographic data using satellite stereo imagery dated geomorphic...

Abstract We reconstruct the incision history of bedrock rivers based on inverse modeling long profile a river channel and low‐temperature thermochronological data. Our approach first infers an erodibility‐dependent through linear inversion elevations river. Then to calibrate reconstructed in geological timescale, we constrain erosional efficiency by optimizing erosion process catchment using Bayesian analysis, such that exhumation cooling paths bedrocks conform observed ages. apply this...

Abstract. We present a deep-learning approach based on the physics-informed neural networks (PINNs) for estimating thermal evolution of crust during tectonic uplift with changing landscape. The approximates temperature field deep network, which is trained by optimizing heat advection–diffusion equation, assuming initial and boundary conditions that follow prescribed topographic history. From network velocity field, one can predict history given rock particle be used to compute cooling ages...
Abstract The Northland Allochthon, an assemblage of Cretaceous–Oligocene sedimentary rocks, was emplaced during the Late Oligocene–earliest Miocene, onto in situ Mesozoic and early Cenozoic rocks (predominantly Eocene–earliest Miocene) northwestern New Zealand. Using low‐temperature thermochronology, we investigate provenance, burial erosion histories from both hanging footwalls allochthon. In central (Parua Bay), overlying allochthon underlying Early Miocene autochthon yield detrital zircon...
SUMMARY The Kepingtag (Kalpin) fold-and-thrust belt of the southern Chinese Tian Shan is characterized by active shortening and intense seismic activity. Geological cross-sections reflection profiles suggest thin-skinned, northward-dipping thrust sheets detached in an Upper Cambrian décollement. 2020 January 19 Mw 6.0 Jiashi earthquake provides opportunity to investigate how coseismic deformation accommodated this structural setting. Coseismic surface resolved with Sentinel-1 Interferometric...
Summary We present a study to estimate the large‐scale landscape history of continental margin, by establishing source‐to‐sink volume balance between eroding onshore areas and offshore basins. Assuming erosion as primary process for sediment production, we strive constrain numerical model evolution that balances volumes eroded materials from continent deposited in corresponding basins, with ratio imposed loss products. use this approach investigate Madagascar since Late Cretaceous.
