Summary: This study focuses on a large-scale hydropower system in the Yarlung Tsangpo-Brahmaputra River Basin and analyzes the potential trade-offs and synergies among hydropower production, waterway navigation, and agricultural irrigation. Through the use of a WEF nexus model, it is found that the reservoir storage can increase hydropower productivity, extend the navigability period, and mitigate flood damage. The development of hydropower in the region has the potential to bring transboundary cooperation and basin-wide benefits.

Summary: This study analyzed various geological samples from the Yarlung Tsangpo River basin to understand the source and isotopic fractionation of dissolved Li in rivers flowing through high-altitude and tectonic regions. The study found that geothermal water and silicate weathering processes have an influence on the increase of 87Li in river water, while continuous Li isotope fractionation is the main reason for the increase of dissolved Li in rivers.

Summary: Profound effects of megafloods on Earth and Mars have been observed. Quaternary megafloods sourced from valley-blocking glaciers on the Tibetan Plateau have played an important role in the geomorphic evolution of the Yarlung-Tsangpo Gorge and eastern Himalaya. Numerical simulations show that the extent of inundated features influences erosional potential, making it difficult to predict local patterns. However, unit stream power and flood power are useful for predicting regional shifts in megaflood flood power. Lower bed shear stresses and potential for significant deposition are observed downstream of the Gorge. These findings suggest that megaflooding in mountainous terrain includes both erosion and deposition.

Summary: This study investigates the Lilong succession in southeastern Tibet, China, confirming its provenance from the central-northern and southern Lhasa Terrane based on observations from petrography, stratigraphy, sedimentology, detrital-zircon geochronology, and bulkrock Sr-Nd isotope analysis. The Lilong succession is proposed to correlate with the Ngamring Formation in the Xigaze forearc basin, suggesting it as a counterpart remnant of the eastern Xigaze forearc basin system, different from the forearc basin systems in the western Himalaya.

Summary: Achondrite meteorites, specifically the ungrouped achondrite Erg Chech (EC) 002, provide valuable information about the formation and evolution of the Solar System. The study indicates that EC 002 is the oldest known igneous crust sample in the Solar System, with a formation age of approximately 4565.87 +/- 0.30 Ma. The analysis of isotopic compositions also reveals an initial 26Al/27Al ratio of about 8.89 +/- 0.79 x 10-6, corresponding to a formation age of approximately 1.83 +/- 0.12 Ma after CAIs. Rating: 8 out of 10.

Summary: This research aims to provide a holistic understanding of the conflict and cooperation in the Yarlung Tsangpo-Brahmaputra River Basin, based on a quantitative analysis of 400 water events spanning 1958-2020. The results surprisingly reveal that the energy and climate imperatives have become catalysts for water cooperation, making water war highly unlikely. However, the lack of attention to cooperative climate mitigation and disputes over food and energy may intensify potential conflict in the basin.

Summary: This study uses detrital zircon U-Pb age distributions to correlate the formations of the Indo-Burman Ranges with equivalent strata in the Bengal Basin. It reveals the early Miocene arrival of the ancestral Brahmaputra delta to the region and the changing sources of sediment through time. Additionally, it suggests that the Miocene progradation of the delta reflects increasing rates of erosion and sea level fall during intensification of the South Asian Monsoon.

Summary: This study presents detailed trace elements, oxygen isotopes, and U-Pb chronology of apatite from the Tianhu metamorphosed sedimentary Fe deposit in Northwest China. The results show that the apatite grains in the deposit have characteristics of metamorphic hydrothermal origin and formation by a single event. The U-Pb dating indicates that the metamorphic enrichment of the deposit occurred considerably later than the Ordovician ore-hosting rocks.

Summary: The research findings reveal that the foreland basin behind the Himalayas is influenced by various factors in geological processes, including basement structure, flexure, and faulting. The subsidence of the foreland basin is mainly controlled by the Indian Plate, and basement features play a crucial role in the development of the foreland basin.

Summary: This study confirms a phase of geological deformation and surface uplift in the Pamir during the middle-late Miocene, indicated by changes in detrital zircon U-Pb age spectra, mudstone bulk-rock epsilon(Nd) values, and stable isotopic values of carbonate cements. These changes suggest different sediment sources and shifts in climate environment.

Summary: The East African rift system is formed above mantle upwellings and the formation of rifts is related to lithospheric thinning and magmatic activity. The amount of splitting varies spatially and the fast axes are predominantly parallel to the orientation of the rifts. Thick lithospheric modules have less splitting and different orientations, which may indicate mantle plume flow. Splitting rotates and increases in strength as it enters the rift zones, suggesting that the anisotropy is mainly present at shallow depths.

Summary: Oxygen fugacity is a fundamental parameter for understanding redox processes in igneous systems. This study compares the Fe-XANES oxybarometry method with the V-in-olivine method for evaluating fO(2) in MORB lavas. The results show that the V-in-olivine method is not applicable to samples with low MgO content, and that the majority of Archean komatiite sources have lower fO(2) than modern MORB.

Summary: The volatile components CO2 and H2O play a major role in mantle melting and heterogeneity. In this study, Ca isotopes were used to trace the lithological heterogeneity in alkaline magmatic rocks. The results revealed the presence of K-richterite and carbonate components as the source of alkaline magmas with low delta 44/40Ca values. These findings highlight the importance of Ca isotopes as a robust tracer of lithological variation caused by volatiles in the Earth's upper mantle.

Summary: Although the current approach to estimate catchment-wide denudation rates using only 10Be concentrations has made significant progress in geomorphology, this study argues for the inclusion of 26Al measurements and testing of steady-state assumptions in slow eroding, formerly glaciated landscapes. The study conducted measurements of both 10Be and 26Al in stream sediments from the Vosges Massif in France and found that elevation, slope, channel steepness, and precipitation were the primary factors controlling denudation rates. The study also revealed a significant relationship between the extent of past glaciation and the cosmogenic (un-)steadiness in the stream sediments.

Summary: Numerical models of Earth's mantle dynamics can predict the vigour and mixing of mantle flow, and the average slab sinking rates are an unexplored parameter that can provide intrinsic information on these characteristics. Through numerical experiments, it has been found that slab sinking rates are strongly correlated with mantle convection and mixing, and may explain geochemical observations from hotspot volcanoes.
