Summary: Research indicates that glacier retreat has accelerated in the eastern Himalayas in recent years, but changes in the distribution of water within the Yarlung Zangbo basin have been observed. Limited glacier melt is mainly occurring in the dry upstream areas, while a larger proportion of snow melt is occurring in the humid downstream areas.

Summary: This study investigated the sedimentology and chronology of the Gangdese conglomerate, which provides insights into the growth process of the southern Tibetan Plateau during the Late Oligocene-Early Miocene. The results suggest that the Gangdese conglomerate was deposited in an extensional tectonic environment in the early period and an extrusion tectonic environment in the late period. The main depositional age of the Gangdese conglomerate was likely the Late Oligocene-Early Miocene, and it trended younger from west to east. Additionally, paleocurrent data indicate the occurrence of a westward axial palaeo-Yarlung-Zangbo River along the Yarlung-Zangbo suture zone during this time period, with the opposite flow direction to the current Yarlung-Zangbo River.

Summary: This study investigates the paleodrainage and timing of exhumation in the interior of the Tibetan Plateau. The results show that an exhumation event occurred between 70 and 40 Ma, followed by low rates of exhumation and the deposition of locally sourced sediment. It is suggested that this event is associated with the development of thrust-elevated relief, which disrupted the drainage network and favored the formation of an internal drainage system and low relief topography.

Summary: The study found significant spatiotemporal variations in dissolved arsenic levels in the Yarlung Tsangpo River system in the Tibetan Plateau, with higher levels in the upper reaches and lower levels in tributaries. Arsenic likely originates from geothermal water and weathering of arsenic-containing rocks and minerals, with conservative transport in the main channel and relatively non-conservative behavior in tributaries.

Summary: Research indicates that the relatively low and flat topography of the Qiangtang Terrane (QT) in the Tibetan Plateau (TP) was mostly formed before 40 million years ago. The QT experienced multiple-stage uplift processes, controlled by crustal thickening before 40 million years ago and lithospheric mantle delamination during the Oligocene.

Summary: The WNW-trending Yangda-Yaxu fault plays a significant role in the regional tectonic deformation in southeastern Tibet. Through paleoseismic research, it has been identified that the fault has a quasi-periodic pattern for major earthquake recurrence intervals, with an interval of approximately 4,000 years. The fault also has a significant control effect on the late Quaternary evolution of nearby faults and plays a crucial role in accommodating crustal deformation.

Summary: This article examines the Cenozoic exhumation history of the SE Tibetan Plateau using joint kernel density estimation and linear inversion methods. The results reveal at least six episodes of rapid cooling since the Cenozoic, with spatially inhomogeneous exhumation throughout the entire plateau. The authors suggest that these cooling events may be attributed to lateral extrusion and continuous convergence between the Indian and Eurasian continents, along with climate changes playing a significant role in shaping the landscape.

Summary: Determining the timing of E-W extension across southern Tibet's NS-trending rifts is crucial for understanding the collision between India and Asia. This study focuses on the Yadong-Gulu rift (YGR) and provides direct time constraints on its onset activity using fault gouge ages and (U-Th)/He dating. The results suggest that the YGR formed around 9 Ma, similar to the northern half. The synthesis of initiation ages from other rifts in southern Tibet reveals a spatial and temporal pattern, with older initiation ages to the west and younger to the east. This challenges previous hypotheses of slab tearing and orogenic collapse, supporting the idea that E-W extension in the Tibetan Plateau is triggered by a combination of eastward propagation of the Karakorum-Jiali fault zone and divergent thrusting along the Himalayan arc.

Summary: This paper investigates the SE Tibetan Plateau in Yunnan, China, and finds that there are abundant Mesozoic crystalline rocks in the region, confirming the existence of basement rocks. Inverse thermal history modeling suggests extensive rapid cooling and exhumation events during the late Oligocene to Miocene, coinciding with large-scale strike-slip fault activities. The study proposes that widespread crustal shortening and thickening occurred in the SE Tibetan Plateau during the Oligocene-Miocene, and the present-day low-elevation landscape of Yunnan is a result of the complex interaction between regional tectonic activity and surficial erosion since the late Oligocene.

Summary: Unraveling the drivers that shape landscape genetics can provide a scientific basis for wildlife conservation and habitat management. In this study, the spatial genetic structure and determining factors of Schizopygopsis younghusbandi, a coldwater fish on the Tibetan Plateau, were explored using mitochondrial cytochrome b gene. The results showed high genetic diversity in higher, colder, and drier areas, and genetic differentiation among geographical populations. The Isolation-by-Environment model explained the genetic structure, with elevation and bioclimatic factors influencing population differentiation. Separate conservation units should be established, with special attention given to marginal populations with lower genetic variation.

Summary: The current structural model for the Longmen Shan belt is an asymmetric orogenic wedge with northwest-dipping thrust faults. The debate lies in how the exhumation of this margin was partitioned into Cretaceous versus Late Cenozoic components. New low-temperature thermochronology data suggests two episodes of exhumation, one during the Late Cretaceous and the other during the Late Cenozoic. A new feature is the large amount of exhumation southeast of the Longriba Fault System, diminishing the asymmetric character of the current structural model.

Summary: The Zhuguangshan complex in South China is the main uranium production area. The study suggests that the tectono-thermal evolution of the central Zhuguangshan complex is influenced by radiation damage, leading to age dispersion in sandstone and granite samples. Thermal history modeling indicates that the LUOF experienced rapid cooling in the Early Cretaceous.

Summary: Observations in Australia showed higher levels of gaseous elemental mercury near power stations generating electricity from low-rank brown coal, with nighttime average values significantly exceeding the Southern Hemisphere average. This highlights the importance of long-term air and soil sampling in power generation regions to understand airborne mercury emissions sources even after coal-fired power stations are closed.

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.
