Mesozoic basins and associated palaeogeographic evolution in North China

Journal of Palaeogeography, 2015
In North China, the Mesozoic terrestrial basins, sedimentary palaeogeography and tectonic settings involved five evolutionary stages: (1) the Early‒Middle Triassic, (2) the Late Triassic to Early‒Middle Jurassic, (3) the Late Jurassic to early Early ...

High‐Precision Delineation of Curie Point Depth Under Remanent Magnetization Using Physics‐Informed Neural Networks

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Curie point depth (CPD), a key indicator of the lithosphere's thermal structure, is typically estimated using spectral analysis or interface inversion methods. However, these approaches often neglect the effects of remanent magnetization, leading to substantial uncertainty.

Climax of Late Paleoproterozoic Rift‐Related Magmatism in the Columbia Supercontinent: Insights From a 1.77–1.76 Ga Large Igneous Province of the Dunhuang Block, Northwest China

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Widespread mafic magmatism at ca. 1.8–1.7 Ga across fragments of the Columbia supercontinent records a transition in the Earth's supercontinent cycle. The paleogeographic position of the Dunhuang Block in northwestern China within Columbia, and its role in this tectonic reorganization, remain controversial.

Geological conditions of coal measures metal enrichment in Linxing block, eastern margin of Ordos Basin

Abstract This study systematically elucidates the multi-scale coupled control system of the metal element enrichment mechanism in coal-bearing strata, revealing its dynamic interaction controlled by structural sedimentation fluid dynamics. Given that traditional geochemical research methods are limited by the spatial limitations of discrete ...

The characteristics and helium generation potential of helium source rocks in the northern Ordos Basin, China

Frontiers in Earth Science
The origin of helium is predominantly governed by helium source rocks, which encompass a spectrum of lithologies, including metamorphic rocks within the basin’s basement, and mudstones, coal, and other rocks in the overlying sedimentary formations.

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.

Large‐Scale Deformation, Strain Characteristics, and Locking Distribution of the Qilian‐Haiyuan Fault System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Qilian‐Haiyuan fault system is the main tectonic boundary of the northeastern Tibetan Plateau, controlling the regional tectonic deformation and seismic activity. Extensive Sentinel‐1 SAR data (2014–2021) are used to map the regional tectonic deformation, strain distribution, and locking along primary and secondary faults.

Herbivore Types as a Key Driver of Spatial Variations in Aboveground Biomass Trends in Alpine Grasslands

Earth's Future, Volume 14, Issue 2, February 2026.
Abstract Managing grazing regimes is a key strategy for promoting the sustainable use of grasslands. The Qinghai‐Xizang Plateau, dominated by alpine grasslands, is subjected to extensive grazing by livestock. Apart from some control experiments, the regional impact of livestock species on alpine grassland has been overlooked, mostly due to the spatial ...

Prediction of geological and engineering integrated sweet spots of deep coalbed methane

Meitian dizhi yu kantan
ObjectiveDeep coalbed methane (CBM) has emerged as a hot topic in CBM resource development. However, deep CBM has characteristics such as great burial depths, complex stress environments, and strong reservoir heterogeneity, which seriously restrict sweet
