Stable Isotope Characteristics and Recharge Mechanisms of River, Lake and Groundwater by Precipitation in the Hulun Lake Basin

Hydrological Processes, Volume 39, Issue 6, June 2025.
Filling the gap in refined research on multimedia hydrological processes during wet seasons in a typical semi‐arid lake basin. The characteristics of δD and δ18O values of the precipitation, river water, lake water and groundwater and their relationships were elaborated, and the recharge rates were calculated among them by using the endmember element ...

Ten Questions of East Asian Tectonics

Acta Geologica Sinica - English Edition, Volume 99, Issue 2, Page 297-319, April 2025.
Abstract East Asian continental tectonics challenges the plate tectonics paradigm with its diffuse intraplate deformation, magmatism, and earthquakes. Despite extensive studies, fundamental questions persist. This review examines ten critical questions of East Asian tectonics, including the thickness of the continental lithosphere, the origin of the ...

Geochemical Constraints on the Generation of Coalbed Methane in the Weizhou Area, South‐Central Ningxia, NW China: Insights From Stable Isotopes and Organic Petrology

Geofluids, Volume 2025, Issue 1, 2025.
Amid growing global clean energy demand, coalbed methane (CBM) in the coal‐rich Weizhou area holds great development value. This study explores Weizhou CBM′s geochemical traits and genesis via analyzing gas compositions (Shanxi and Taiyuan Formations), stable isotopic distributions (δ13C1, δD, δ13CO2, and δ15N), and their burial depth variations ...
