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

open access: yesGeophysical 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.

Influence of pre-Andean history over Andean foreland deformation: structural styles in the Malargüe fold-and-thrust belt at 35ºS, Andes of Argentina [PDF]

open access: yes, 2014
We present the first complete balanced cross-section of the Argentinean Andes at 35ºS. Based on an extensive field survey and limited sub-surface information, we constructed a structural model in which both the tectonic inversion of Mesozoic normal ...

Phase Relations and Melting of SiO2 Under Mantle Conditions Determined From Machine Learning Potentials

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract SiO2 is a fundamental component of planetary interiors, yet its high‐pressure melting and phase relations remain uncertain. We develop a machine learning potential with first‐principles accuracy and perform large‐scale two‐phase coexistence simulations to determine the melting curves of stishovite, post‐stishovite, and seifertite up to 160 GPa

Geochemical characteristics, origin and main controlling factors of helium gas accumulation of helium-bearing natural gas in Sulige Gas Field, Ordos Basin, China

open access: yesJournal of Natural Gas Geoscience
The Ordos Basin is the largest natural gas producing region in China. Recent discoveries of two helium-rich natural gas fields (Dongsheng and Qingyang) shows promising helium resource potential.

Distribution and genesis of large-scale Upper Paleozoic lithologic gas reservoirs on Yi-Shaan Slope

open access: yesPetroleum Exploration and Development, 2008
Lithologic reservoirs are widely distributed at Upper Paleozoic of Yi-Shaan Slope in Ordos Basin. With over 40 years of exploration, six large gas fields were discovered, including Sulige, Wushenqi, Yulin, Daniudi, Zizhou, and Mizhi, with total proved ...

Crustal Responses to the Destruction of Continental Lithosphere: Insights From Radial Anisotropy of the Tanlu Fault Zone, Eastern China

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

Physical and environmental drivers of Paleozoic tetrapod dispersal across Pangaea

open access: yesNature Communications, 2018
The late Paleozoic was a time of major transition for tetrapods. Here, Brocklehurst and colleagues analyse the biogeography of Paleozoic tetrapods and find shifts in dispersal and vicariance associated with Carboniferous mountain formation and end ...

The Mesozoic along-strike tectono-metamorphic segmentation of Longmen Shan (eastern Tibetan plateau) [PDF]

open access: yes, 2018
The Longmen Shan belt (eastern border of the Tibetan plateau) constitutes a tectonically active region as demonstrated by the occurrence of the unexpected 2008 Mw 7.9 Wenchuan and 2013 Mw 6.6 Lushan earthquakes in the central and southern parts of the ...

Application and Evaluation of a NOAA GFS‐Driven Air Quality Model Using CMAQv5.4 and High‐Resolution Emissions: FIREX‐AQ 2019

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The National Air Quality Forecast Capability (NAQFC) provides numerical forecasting guidance of air quality up to 72 hr ahead over the United States. In this study, we evaluate the changes in its prediction skills by updating the Community Multiscale Air Quality (CMAQ) modeling system from version 5.3.1 to 5.4 and utilizing a high‐resolution 1‐

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.
