Despite longstanding research on the age and formation of the Tibetan Plateau, the controls on the erosional decay of its margins remain controversial. Pronounced aridity and highly localized rock uplift have traditionally been viewed as limits to the dissection of the plateau by bedrock rivers. Recently, however, glacier dynamics and landsliding have been argued to retard headward fluvial eros...

Himalayan orogenesis remains enigmatic in terms of Tibetan Plateau geodynamics originating from the Cenozoic India–Eurasian continental collision. India underthrusts below Tibet to Yarlung–Tsangpo suture, which has been identified as northernmost boundary for underplating. However, way historical evolution subduction induces plateau uplift and it controls variation between outboard inboard area...

Fast and accurate relative positioning for baselines less than 20 km in length is possible using dual-frequency Global Positioning System (GPS) receivers. By measuring orthometric heights of a few GPS stations by di€erential levelling techniques, the geoid undulation can be modelled, which enables GPS to be used for orthometric height determination in a much faster and more economical way than ...

The collision of India with Asia, one of the most profound tectonic events to have occurred in past 100 m.y., is thought to have had geological, geochemical, and climatological consequences of global extent. Surprisingly the age of initiation of this collision remains poorly constrained. Estimates range from the Late Cretaceous (.65 Ma) to latest Eocene (,40 Ma), with little consensus in betwee...

In order to investigate the hydrochemical characteristics and their controlling factors, 212 water samples from Yarlung Tsangpo River its tributaries were collected over three precipitation periods in 2018 analyzed using mathematical statistics, Gibbs ion ratio methods, principal component analysis. The results showed following: (1) cations mainly Ca2+, Na+ Mg2+, anions HCO3− SO42− predominant,...

Abstract. On 22 March 2021, an approximately 50 Mm3 ice-rock avalanche occurred from 6500 m a.s.l. in the Sedongpu basin, southeastern Tibet. The transformed into a highly mobile mass flow which temporarily blocked Yarlung Tsangpo river. lasted ∼ 5 min and produced substantial geomorphological reworking. This event, previous ones concurrently with, or shortly after, positive seasonal air temper...

Abstract The Jiacha Gorge in southeastern Tibet is the second-largest deeply incised gorge of Yarlung-Tsangpo River, after Tsangpo Gorge. A late Cenozoic N-S–trending normal fault, Woka Rift coincides with western limit gorge. However, relationship between formation gorge, drainage evolution, and rift activity remains unclear. Analysis river long profile suggests that developed as a ~45-km-wide...
