Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...

The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations

Deep Underground Science and Engineering, Volume 5, Issue 3, Page 728-753, September 2026.
Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Bayesian Modeling of Crustal Azimuthal Anisotropy Supports Partial Crust–Mantle Anisotropic Decoupling in a Continental Back‐Arc, Northeast China

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract How crustal deformation responds to complex mantle flow in continental back‐arc settings remains poorly constrained. Here, we develop a Bayesian working‐likelihood approach to estimate crust‐averaged azimuthal anisotropy from P‐wave receiver functions. The method separates crust‐averaged velocity anisotropy from dip‐related apparent anisotropy

Occurrence and distribution of series long-chain alkyl naphthalenes in Late Cretaceous sedimentary rocks of the Songliao Basin, China

, 2011
A pair of series straight long-chain 2- and 1-alkyl naphthalenes (aNs) with alkyl chain carbon number up to 30 was detected in late Cretaceous sedimentary source rocks of the onshore Songliao Basin, NE China.

Joint Identification of Groundwater Contamination Source and Heterogeneous Hydrogeological Parameters in LNAPL‐Contaminated Sites Based on Deep Convolutional Encoder‐Decoder Neural Networks

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Accurate identification of nonaqueous phase liquid (NAPL) contamination sources is critical in pollution management. However, the joint inversion of source characteristics and heterogeneous hydrogeological parameters faces two major challenges.

Crustal thickness and vP/vS ratio and their tectonic implication in Jilin Province

地震科学进展
Using data on crustal thickness and the vP/vS ratio calculated from teleseismic waveforms recorded at five temporary stations and collected from previous studies in Jilin Province, we analyzed the crustal structure in different geological units.
