Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Mo Isotopic Records Imply Persistent Ocean Oxygenation in the Deep Southwest Pacific During the Early Cenozoic Warming Period

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract During the early Cenozoic greenhouse period, counterintuitive contractions in tropical Pacific oxygen‐deficient zones have been linked to enhanced deep‐ocean ventilation, yet direct geological evidence remains limited. Here we present molybdenum (Mo) isotopic records from International Ocean Discovery Program Site U1509.

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

Journal 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

Petroleum 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 ...

Unexpectedly High Accumulation Rates in the 2022 Mt. Logan Ice Core Reveal Warm‐Season Drivers of Precipitation Variability

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Ice cores from Mt. Logan, the second highest peak in North America located in the St. Elias mountains in southwest Yukon, Canada, have provided conflicting accumulation records, thus the hydroclimate response to changing atmospheric conditions in the highest elevation regions is not well constrained.

PALEOZOIC LEPOSPONDYL AMPHIBIANS [PDF]

American Zoologist, 1965
The lepospondyls are urodele-like amphibians of the Paleozoic Era, some of which have been considered ancestral or closely related to reptiles or modern amphibians. Their origin is enigmatic, and the earliest occurrences reveal a long-established division into three contrasting orders: the serpentine aistopods, the newt-like nectrideans and the ...

Rupture Cascade Initiated by Wastewater Disposal: Nucleation and Domino Effect of Canada's Largest Induced Earthquake

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.
