Two Cycles of Devonian–Triassic Extension and Compression in the Altai Accretionary Wedge: Insights From Tsogt Core Complex

open access: yesTectonics, Volume 44, Issue 12, December 2025.
Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

Spatiotemporal Variations of Terrestrial Water Storage and Driving Factors in the Water Towers of Northwest China Based on GRACE and Multi‐Source Data Sets

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Mountains represent important water towers and thus are the primary water suppliers for downstream areas. However, divergent trends in terrestrial water storage (TWS) in water towers and their driving factors have not been clarified. This study investigated water tower units (WTUs) in Northwest China (NWC) and used GRACE/GRACE‐FO and multi ...

Triassic Intracontinental Crustal Reworking of the Eastern Tianshan: New Insights From Late Triassic Adakitic and Low‐Sr/Y Granitoids in the Bogda Range

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Continental intraplate magmatism remains a fundamental challenge in Plate Tectonics. Triassic magmatism represents a critical phase in the evolution of the Central Asian Orogenic Belt and continues to provoke debate about its tectonic setting.

Seeing China's Invisible Groundwater: Advances and Challenges

open access: yesWater Resources Research, Volume 61, Issue 6, June 2025.
Abstract In 2021, China adopted comprehensive “Groundwater Management Regulations” to address critical groundwater issues, building upon the foundation of a national groundwater monitoring network established by 2020. This commentary reviews the development of China's National Groundwater Monitoring Network, examines its current monitoring capacity ...

Carboniferous Barrovian to Permian Buchan‐type metamorphic cycles in the Mongolian Altai Zone: Implication for pressure cycles in accretionary orogens

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 7, Page 979-1033, September 2024.
Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, the timing and link between these cycles are not clear, and their causes are debated. In order to contribute to the understanding of Barrovian‐ to Buchan‐type evolution of the accretionary wedges, we

A Refined Supply‐Demand Framework to Quantify Variability in Ecosystem Services Related to Surface Water in Support of Sustainable Development Goals

open access: yesEarth's Future, Volume 12, Issue 5, May 2024.
Abstract As water‐related ecosystem services (WRES) encounter unprecedented threats with climate change and human activities, it is important to understand the impact of variations in the supply and demand for WRES on Sustainable Development Goals (SDGs).

Environmental DNA reveals the ecology and seasonal migration of a rare sturgeon species in the Ural River

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
Environmental DNA technology has been used to identify rare sturgeons in the Ural River. The study found sturgeons at all sites in spring and autumn, confirming their semi‐anadromous ecology. This is the first documented eDNA detection of sturgeon specimens in the Ural River.

Classification and mechanism of spring and summer floods in northern Xinjiang from 2006 to 2011

open access: yesAtmospheric Science Letters, Volume 25, Issue 2, February 2024.
Proportion of three types of flood events in different months (orange: rainstorm‐type floods; blue: warming‐type floods; green: mixed‐type floods). In this study, floods that occurred in northern Xinjiang from 2006 to 2011 were divided into three categories: rainstorm type, warming type, and mixed type.
