Abstract:

As one of the global high-altitude fluvial-aeolian system distribution areas, the Yarlung Zangbo River Valley exhibits widespread and distinctive aeolian landforms, particularly represented by climbing dunes developed on valley slopes. Serving as crucial components of desertification landscapes in the Yarlung Zangbo River Valley, previous studies have primarily focused on the dune distribution and morphology, material composition, dynamics and flow field features. However, works on its material source and its migration and transformation with other sources such as fluvial sediment, as well as the formation and evolution history over a longer time scale, are still relatively inadequate. Systematic chronological investigation is the foundation for studying desert and sandy land evolution, as well as for accurately understanding the climatic context of dune formation and development. Current chronological data of aeolian sands in the Yarlung Zangbo River Valley mainly concentrate after 30 ka BP, with a notable assemblage on the period of after 13 ka BP. Records of aeolian sands older than 30 ka BP are almost absent. The formation and evolution of climbing dunes within the Yarlung Zangbo River Valley as well as its mechanisms constitute a focus for future research. Especially, selecting climbing dunes at multiple sites and employing effective drilling techniques/equipment to obtain high-resolution chronology and proxy data along the extension direction and vertical accumulation direction are crucial for reconstructing their formation and evolutionary history.
