Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Carbonate Clumped Isotopes (Δ47) in Cenozoic “Island Dolostones”: Dolomitization Driven by Modified Seawater at Earth‐Surface Conditions

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Dolomite [CaMg(CO3)2] is abundant throughout the geological record and constitutes a major component of many ancient carbonate platforms, yet the mechanisms responsible for its formation under Earth‐surface conditions are equivocal. Given that modern examples of low‐temperature dolomitization are rare, Cenozoic “island dolostones” provide ...

Paleotemperature modeling of hydrocarbon generation centers and their role in the formation of «Paleozoic» oil deposits (Ostaninskoe field, Tomsk region)

open access: yesGeoresursy
Study and exploration of the pre-Jurassic oil and gas complex in Western Siberia is one of the aspects of hydrocarbon raw-material base development. The main scope of this study is to locate the source of Paleozoic hydrocarbons.

Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Attention and Geological Knowledge Guided Spectral‐Spatial Networks for Geochemical Anomalies Recognition

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Achieving both accuracy and interpretability in deep learning models for geochemical anomaly recognition constitutes a significant challenge. To overcome this challenge, this study developed a novel interpretable dual‐branch network combining a spectral attention bidirectional RNN (BiRNN) branch and a spatial attention CNN branch guided with ...

Merged Interplanetary Data From L1: MIDL

open access: yesSpace Weather, Volume 24, Issue 8, August 2026.
Abstract The availability and accuracy of upstream solar wind conditions are critical for solar wind—magnetosphere coupling studies, whether based on observations or numerical models and simulations. We present the Merged Interplanetary Data from L1 (MIDL), which merges 1‐min magnetic field and plasma observations from ACE, DSCOVR, and Wind through a ...

Late Cenozoic Convergence Between the Pamir and the Tianshan Revealed by Low‐Temperature Thermochronology

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Cenozoic India–Eurasia collision drove widespread deformation across Central Asia, culminating in northward indentation of the Pamir and its eventual contact with the South Tianshan. However, the timing and kinematics of Pamir–Tianshan convergence, as well as its influence on regional topography and climate, remain debated. Here, we report

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

Cultural geography of heat: Artistic experiments with heat’s animacies

open access: yesGeographical Research, Volume 64, Issue 3, August 2026.
A sustained, cultural geographical engagement with heat is long overdue. I advance this agenda by engaging with the work of contemporary artists. Artists are responding to uneven conditions of global heating by exploring heat’s animacies: how heat interweaves with the practices and textures of life.

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...
