Sediments from the same river are typically thought to reflect a common provenance, even though they may record notably different, and opposite, sediment supply erosion signals. Such discrepancies can introduce significant bias into our interpretation of geomorphological processes. This study focuses on Yarlung Tsangpo, Tibetan headwaters Brahmaputra River, contrasts mineralogical geochemical information suspended load in transit fluvial bars reveal major discrepancy budgets calculated with...
Two sediment cores recovered in the central part of Daihai Lake north-central China were analysed at 2-to 4-cm intervals for total inorganic and organic carbon (TIC TOC) concentrations. The TIC concentration is inferred to reflect temperatures over lake region an increase implies temperature. TOC considered precipitation basin higher concentrations denote more precipitations. Thus AMS 14 C time series records sediments uncovers a detailed history changes temperature during last c. 12 000 yr....

Abstract As the most recent collisional event prior to early Cenozoic India‐Asia collision, suturing of Lhasa‐Qiangtang terranes resulted in crustal accretion and formation lithospheric structures that greatly influenced subsequent rock uplift central Tibet. The discovery several microcontinents within Bangong‐Nujiang suture zone between Lhasa Qiangtang potentially implies multiple stages, however, how when these occurred are highly disputed. Here, we present a newly discovered latest...
Studying the grain-size dependent compositional variability in modern river sediments provides a key to decipher information stored sedimentary archive and reconstruct evolution of Earth's surface past. Bedload sand along Xigaze cross section Yarlung Tsangpo (upper Brahmaputra River) ranges mean grain size from 0.72 Φ 3.21 Φ, is moderately poorly sorted slightly platykurtic leptokurtic with sub-angular sub-spherical grains. Litho-feldspatho-quartzose feldspatho-litho-quartzose (Q 43%–65%; F...
Abstract River‐fed dune fields characterized by relatively low quartz content are much more common on Earth than generally assumed, and the aeolian field system in Yarlung Tsangpo (Upper Brahmaputra) river catchment is considered a typical example. As one of highest‐altitude fluvial‐aeolian systems Earth, different wide tracts valley, made sand entirely blown from adjacent bed, provides an excellent natural laboratory which to investigate diverse factors controlling textural compositional...
Abstract The Yarlung Tsangpo, draining the Himalayan‐Tibetan orogen along Indus‐Yarlung suture zone, receives detritus from deformed remnants of both Indian margin to south and Asian north. High resolution petrographic, heavy‐mineral geochemical datasets, combined with published geochronological data, allow us monitor compositional changes, estimate erosion rates investigate lithologic, climatic anthropic controls on sediment fluxes this large sediment‐routing system entirely developed...
As a Quaternary repository of wind-reworked Indus River sand at the entry point in Himalayan foreland basin, Thal Desert northern Pakistan stores mineralogical information useful to trace erosion patterns across western syntaxis and adjacent orogenic segments that fed detritus into delta huge deep-sea fan throughout Neogene. Provenance analysis was carried out by applying optical semi-automated Raman spectroscopy on heavy-mineral suites four eolian 11 fluvial samples collected selected...
Abstract The controversial history of Indian subduction beneath Asia is crucial to understand the Himalayan orogeny and more in general geodynamic process continental subduction. New key information here presented from Oligocene‐Pliocene Shiquanhe Basin located southwestern Tibetan Plateau. alluvial‐fan, lacustrine, braided‐river sediments Oligocene Rigongla Formation were non‐conformably deposited onto Upper Cretaceous Gangdese granitoid rocks fed erosion batholith itself associated...
The study on soft-sediment deformation structures (SSDS) of Lingshan Island has been one the hot topics sedimentology researches in China recent years, and SSDS developed turbidite system Laiyang Group are widely known by domestic researchers. However, few studies were conducted fan delta Qingshan Group, Island. This analyzes classification characteristics especially their lithofacies association lithologic through field outcrops investigation thin section analysis as well. A conclusion was...
Abstract In the case of modern river sediments, source rocks, tectonic setting, and climatic geomorphological conditions are fully known, diagenetic effects by definition none, physical chemical processes during erosion, transport, deposition can be investigated directly in any required detail. Their study thus provides fundamental information needed to understand impact various controls on sediment generation routing systems diverse geological settings. With growing interest source‐to‐sink...

Abstract The Namche Barwa Syntaxis (NBS) is one of the most productive detrital factories on Earth. Previous studies have shown that NBS supplies large amounts sediment to Brahmaputra River, although sources and controlling factors production not been ascertained in detail. This study presents petrographic heavy‐mineral data for 43 sand samples collected Yarlung Parlung river catchments covering entire surrounding areas. Combined with U–Pb ages zircons, our indicate 89 ± 11% River sediments...
This special issue of Mesozoic is dedicated to the memory a great specialist in carbonate sedimentology, Dr Juan Li, who passed away on July 19th, 2023. Li sadly left us while logging Paleocene-Eocene thermal maximum (PETM) interval Tibetan Himalaya. has collected contributions Mesozoic–Cenozoic geological studies from Qinghai-Tibet Plateau colleagues, friends, and fellow scientists express our remembrance regret.
Abstract The timing of the initiation present‐day tectonic architecture and drainage systems in eastern China remains debated. This study presents a comprehensive provenance Early Jurassic peripheral basins surrounding Dabie orogen including framework petrography, heavy‐mineral analysis, single‐grain chronology chemistry. Clasts high‐grade schist, muscovite grains, rare gneissic fragments, abundant metamorphic garnet phengite (Si > 3.3 pfu), combined with main 216–256 Ma rutile U–Pb...
The "underfilled trinity" model of foreland-basin stratigraphy was proposed based on the observation that initial sedimentary stages along western and northern front central Alps were represented by shallow-water carbonates (Calcaires à Nummulites) overlain hemipelagic marls (Marnes Bleues) capped siliciclastic turbidites (Grès d'Annot). Subsequently, this has been widely accepted applied in foreland basins worldwide. We here re-investigated Eocene-Oligocene succession Western to check its...
