In order to better constrain the evolution of Tethyan orogenic system, we conducted an integrated investigation involving U-Pb dating igneous and detrital zircon, geochemical analysis rocks, compositional sedimentary strata, a synthesis existing work across Qilian Shan, Qaidam Basin, Eastern Kunlun Range central northern Tibet. This effort reveals five stages arc magmatism at 1005–910 Ma, 790–720 580–500 490–375 290–195 respectively. Arc activities were interrupted by repeated...
Our understanding of the assembly history Asia depends critically on tectonic relationships between its major cratons, including Siberia, North China, South and Tarim. The intervening microcontinents these cratons can provide insight into paleogeographic paleotectonic but there is currently a general lack knowledge regarding basement geology microcontinents. Here we present results from systematic geologic mapping, U-Pb zircon dating, whole-rock geochemical analysis, synthesis existing data...
The topography evolution of the southeastern Tibetan Plateau provides a constraint for evaluating various geodynamic models plateau formation. We reconstruct Paleocene to Eocene paleoelevation Cenozoic Gonjo basin in Qiangtang terrane, using oxygen and carbon stable isotopic results from pedogenic carbonates lower Ranmugou Formation. Lithofacies associations indicate that Formation was deposited alluvial fan fluvial floodplain environments. U-Pb dating volcanics within middle constrains...

Sediment supply to the ocean influences basin-margin growth and reflects upstream landscape evolution, including patterns of sediment routing, denudation, tectono-climatic perturbations in source areas. Constraining is useful for inputs stratigraphic forward models predictions reservoir presence quality. Because importance supply, geoscientists have developed various methods estimate it. Here, we apply Monte Carlo simulation (MCS) BQART model that used describe an empirical relationship...
ABSTRACT In contrast to the high-frequency and high-amplitude sea level changes of icehouse times, eustatic in greenhouse times are now generally accepted as significantly lower frequency amplitude. As a corollary this, extent cross-shelf shoreline transits also likely have been modest by comparison, it has suggested that deltas may docked at shelf edge for long periods, thus delivering sediment deep-water areas more frequently. A revisit upper Paleocene–lower Eocene Wilcox data across south...
Abstract Well‐constrained fault slip rates are important for understanding strain partitioning within a system and the associated seismic hazard. The Haiyuan is significant active strike‐slip in northeast margin of Tibetan Plateau with ongoing controversy over its late Pleistocene rate. Previous work by Lasserre et al. (1999) suggested rate 12 ± 4 mm/year, which higher than recent geodetically determined on adjacent sections. We reanalyze reevaluate benefiting from new high‐resolution...
River incision results from interactions among tectonics, climate change, and surface processes, yet the role of each process operating at different time scales remains poorly understood. In this study, we address issue by reconstructing late Quaternary spatiotemporal variation aggradation rates along Lancang (Upper Mekong River) in southeast Tibet. Our work combined field observations, topographic data analysis, optically stimulated luminescence (OSL) cosmogenic radionuclide (CRN) dating...
Abstract To better constrain the long-term millennial slip rate of Haiyuan fault in its central part, we revisited site Daqing, where there are multiple paired offset terraces. We used 0.1-m-resolution terrestrial light detection and ranging (LiDAR) uncrewed aerial vehicle imagery to survey terraces, quantify their geomorphology, map trace. From these observations, refined geomorphological interpretation site, measured terrace riser offsets, determined relation formation. The...
Abstract Classic sequence stratigraphy suggests depositional sequences can form due to changes in accommodation and sediment supply. Accommodation‐dominated are problematic define rigorously, but commonly interpreted from outcrop subsurface data. In contrast, supply‐dominated much less identified. We employ numerical stratigraphic forward modelling compare stratal geometries forced by cyclic relative sea level with discharge water changes. Our quantitative results suggest that both sea‐level...
Abstract Marine shelves are a ubiquitous feature of modern Earth, developed across wide range scales in many sedimentary basins and representing the flooded portion basin-margin clinoform topsets. Analysis 80 clinoforms from 10 spanning Cenozoic Mesozoic icehouse, transitional, greenhouse climate settings indicates that normalized mean marine shelf width is 33% total measured topset length. The equivalent value for transitional 43%, 72% icehouse shelves. These values demonstrate were...
Abstract Geometrical complexities such as bends and branches are ubiquitous along strike‐slip faults. Understanding strain partitioning between the different fault strands sections is key to assessing kinematics evolution through time of a system related seismic hazards. The Haiyuan fault, one longest faults Tibetan Plateau, has developed multi‐stranded complex geometry Hasi Shan restraining bend. In this study, we quantified slip rate ∼50‐km‐long Zihong which poorly‐known southernmost...
Abstract Induced earthquakes are becoming a significant issue. Several destructive induced (Ms ≥5.0) have occurred in shale gas fields located at the southwestern Sichuan basin, China, recent years. Specifically, two moderate with magnitudes of Ms 5.4 (occurred on 8 September 2019) and 5.2 18 December exceeded largest earthquake ever recorded Weiyuan. It remains unclear which seismogenic faults were responsible for events due to insufficient knowledge subsurface structure contradictory...
