Source of the Upper Paleozoic natural gas in the Dingbei area, Ordos Basin, China

Journal of Natural Gas Geoscience, 2019
The Dingbei area is an important exploration area in the Ordos Basin for SINOPEC, and natural gas exploration in the Upper Paleozoic strata in the area achieved a great breakthrough in recent years.

Similar Material Simulation Study on Dam Movement and Deformation Law of Deep Coal Seam Mining Under Dam

Energy Science &Engineering, Volume 14, Issue 4, Page 1808-1821, April 2026.
Aiming at the difficulties in accurately calculating the movement and deformation of small‐sized, deep‐buried dams with a significant height‐to‐depth ratio in deep fully mechanized caving mining, this study proposes to separate the analysis of surface and dam deformation.

Depocenter migration of the Ordos Basin in the late Triassic and its controls on shale distribution

, 2017
The Ordos Basin has abundant conventional and unconventional oil and gas resources. Focusing on shale oil in the Ordos Basin, we studied the distribution, depositional features, and resource potential of shales in the upper Triassic Yanchang Formation ...

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.

Measurement of Phase Velocity and Ellipticity of Multi‐Mode Surface Waves by Beamforming Multi‐Component Ambient Seismic Noise

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Conventional beamforming of multi‐component ambient seismic noise typically utilizes only the vertical‐vertical (ZZ) component to extract Rayleigh wave dispersion curves or the transverse‐transverse (TT) component for Love waves. In this study, we extend weighted and modified beamforming to cross‐correlation functions between different ...

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.

A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Unconventional Natural Gas Accumulations in Stacked Deposits: A Discussion of Upper Paleozoic Coal‐Bearing Strata in the East Margin of the Ordos Basin, China

Acta Geologica Sinica - English Edition, 2019
The Upper Paleozoic (Carboniferous to Permian) succession in the east margin of the Ordos Basin in the North China Craton has a potential to contain significant hydrocarbon resources, though attention have been mainly attracted for its successful ...
