Radon‐222 as an Effective Tracer to Distinguish Groundwater Circulation Patterns in the Deep Fault‐Controlled Geothermal System

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Groundwater flow regulated by deep faults remains challenging to trace due to structural complexity. This study applies the noble gas tracer 222Rn combined with hydrochemistry and stable isotopes (δ2H, δ18O) to distinguish circulation patterns of geothermal springs along a major fault in the Tibetan Plateau.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, Volume 61, Issue 5, Page 1291-1309, May 2026.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

When Snowpacks Shrink: Declining Weathering and Export Rates but Rising Stream Solute Concentrations in Warming Mountains

Hydrological Processes, Volume 40, Issue 5, May 2026.
In a snow‐dominated headwater catchment, snow‐dependent water storage controls silicate weathering and solute export. In the driest year with the least snow water equivalent (SWE), rates of silicate weathering and export rates of weathering products were about half and a third of those in the wettest year with the highest SWE.
