Abstract The establishment of continental-scale drainage systems on Earth is largely controlled by topography related to plate boundary deformation and buoyant mantle. Drainage patterns the great rivers in Asia are thought be highly dynamic during Cenozoic collision India Eurasia, but pattern landscape evolution prior development high eastern Tibet remain unknown. Here we report results petro-stratigraphy, heavy-mineral analysis, detrital zircon U-Pb dating from late Cretaceous–early...
Abstract Previous studies suggest that the northeastern Tibetan Plateau has been major source area for Chinese Loess (CLP); this contribution was used to prove Yellow River played a dominant role in transporting materials from Plateau, making them available CLP. Accordingly, proximal North China Craton is considered have increased supply potential of dust CLP further eastward. However, origin eastern and relationship between loess river sediments never systematically studied, which prevents...
Abstract The downstream grain size variation along active river channels has been a long‐standing topic for fluvial geomorphologists. However, identifying the influence and controls on change in bed sediment texture is not straightforward. In this study, we investigated lithological composition of bedrock riverbed gravels, rock strength distribution gravels within three rivers flowing out Longmenshan Mountain eastern Tibetan Plateau where human disturbances are locally occurring, to examine...
This study examines the impact of temperature and humidity on cotton fiber quality during initial processing. Conducted in a Xinjiang ginning mill, we used USTER HVI1000 to analyze five indices: upper half mean length, uniformity, short index, tensile strength, elongation. Results indicated that temperatures below 13°C increased brittleness, moisture, significantly reduced length strength. Optimal conditions were observed at between 20°C with normal humidity, where strength maintained. Above...
Abstract The drainage evolution in eastern Tibet during the India‐Eurasia collision has attracted considerable attention because of its critical link to topographic development and plateau growth, but discussion still persists. In present study, new published detrital zircon U‐Pb ages are integrated from Pliocene‐Early Pleistocene Xigeda Formation (XGD) modern river sands decipher paleo‐drainage Tibet. results confirm eastward flow Jinsha River before Pliocene, patterns major tributaries...
Abstract The modern high topography of the eastern Tibetan Plateau is drained by several largest rivers on Earth, and exerts a prominent influence Asian monsoon pattern. However, when terrain was formed remains highly debated. Here, we present detrital zircon U‐Pb ages that indicate south‐flowing drainage system with distal headwaters passed through Ninglang Basin at ca. 45 Ma. We advocate for early–middle Eocene surface uplift in Gonjo areas to west creating southeast tilted across Tibet....
Abstract The formation age of the middle Yellow River and existence a northward‐flowing river have been fiercely debated. distribution detrital zircon varied spatiotemporally produced contradictory provenance interpretations. Jinshaan Gorge, main part key to studying fluvial evolution clarifying disputes, developed its topography during late Cenozoic. In this study, we systematically review Cenozoic tectonic North China Craton, perform U–Pb dating in Neogene−Quaternary sediments investigate...
Abstract The Chinese Tian Shan is one of the most actively growing orogenic ranges in Central Asia. Late Miocene‐Quaternary landscape evolution northern has been significantly driven by interaction between tectonic deformations and climate change, further modulated erosion upstream bedrocks deposition into downstream basins. In this study, only accessible Kuitun River drainage basin was considered, detrital zircon geochronology heavy minerals were analyzed to investigate signature driving...
Abstract The uplift and deformation styles of the Tibetan Plateau have been long debated on stepwise growth crustal channel flow. Here, we offer new insight into this issue by constraining pulsed exhumation history Yalong thrust belt in eastern Tibet, using apatite zircon (U–Th)/He data from three ∼1 km vertical transects. results revealed two rapid cooling pulses Late Oligocene (∼24 Ma, 50°C/m.y.) Middle Miocene (17–14 35 °C/m.y.), respectively, which ascribe to staged‐thrusting faulting...

阿尔金断裂带是青藏高原自印度与欧亚大陆碰撞后向北扩展的前缘断裂,其新生代活动性对于研究青藏高原隆升与扩展过程和机制具有重要意义。近些年,运用热年代学、断裂几何学和运动学、沉积学、磁性地层学和地震学等方法对阿尔金断裂带的性质、组成结构、断裂活动时代、走滑断裂运动特征、走滑位移量和走滑速率等进行了细致的研究,而对阿尔金断裂带沿线受其控制的新生代沉积盆地的地层年代、沉积演化特征虽然也有一定研究,但往往仅限于单个盆地,缺乏对沿线盆地整体的对比认识,造成对阿尔金断裂带走滑起始时间及阿尔金山的隆升历史存在不同的认识。本文对近二十年来阿尔金断裂带沿线新生代沉积盆地的磁性地层年代与沉积相演化的研究进展进行综述,建立阿尔金断裂带沿线盆地新生代沉积序列和年代框架;辅助热年代学等资料,提出阿尔金断裂带的三阶段演化模型:始新世-中中新世,阿尔金断裂带以大幅度的走滑运动为主,同时伴随着阿尔金山小范围的隆升;中中新世开始,阿尔金山开始大规模的隆升,伴随着较少量的走滑运动;晚中新世以来,阿尔金断裂带构造活动加强。;The Altyn Tagh fault is the frontal in...
The exhumation history of the Central Tibetan Mountain Range (CTMR) in Qiangtang terrane is important for establishing boundary conditions prior to India-Asia collision. Previous studies suggest that CTMR a significant provenance Jurassic sediments terrane. Middle north provide crucial information constrain timing source area. Here we present detailed stratigraphic sections and detrital zircon U-Pb geochronology northern basin. Sedimentary facies analyses indicate Early-Middle Quemoco...
The mechanisms of the upward and outward growth Tibetan Plateau are crucial for understanding geodynamic significance Cenozoic continental collisions. Northeastern Tibet has been suggested as one youngest deforming uplifting margins surrounding plateau. existence fluvial knickpoints low-relief topographic surfaces along Yellow River its tributaries indicate transience landscape in response to active tectonic uplift. Therefore, uplift history North Eastern (NETP) can be potentially inverted...
The height of a thrust-fault scarp on fluvial terrace would be modified due to erosion and deposition, these surface processes can also influence the dating terraces. Under such circumstances, vertical slip rate fault misestimated inaccurate displacement and/or abandonment age terrace. In this contribution, considering effect deposition scarps, we re-constrained west end Minle–Damaying Fault (MDF), one thrusts in north margin Qilian Shan that marks northeastern edge Tibetan Plateau....
Abstract The anisotropy of magnetic susceptibility (AMS) has great potential in deciphering weakly deformed fabrics that may be related to tectonic stress. Previous studies have suggested lineation is a good indicator paleostrain direction. It unclear whether the fabric can also used indicate present‐day strain field. To verify this idea, we measured AMS freshly consolidated lacustrine fine‐grained sediments at 11 locations Qaidam and Chaka‐Gonghe basins northeastern Tibetan Plateau compared...

Late Miocene-Quaternary landscape evolution northern has been significantly driven by interaction between tectonic deformations and climate change, further modulated erosion upstream bedrocks deposition into downstream basins. In this study, only accessible Kuitun River drainage basin was considered, detrital zircon geochronology heavy minerals were analyzed to investigate signature driving forces for...
Stream-channel offsets are widely used for identifying strike-slip faults and estimating fault slip rates. Most have the component of dip-slip motion. Here, we a landscape evolution model to investigate role in creating maintaining stream-channel environment. Our results show that length is primarily controlled by vertical rate difference (VSRD) between above part below part. The average cumulative stream channels positively associated with VSRD negatively related positive leads...
