Selection of strategic replacement areas for CBM exploration and development in China

Natural Gas Industry B, 2015
At present, the increase in proved reserves and production of coalbed methane (CBM) in China depends mainly on several CBM bases in the southern Qinshui Basin and in the eastern margin of the Ordos Basin.

Characteristics of In Situ Stress and Reservoir Pressure in Deep Coal Seams and Their Influences on Reservoir Depletion: A Field Case Study

Geofluids, 2023
The production of coalbed methane resources is greatly dependent on the reservoir depletion process. To improve the depressurization efficiency of deep coalbed methane (DCBM) reservoirs, the fluid production characteristics and implications of in situ ...

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Cannibalism of contourites by gravity flows: explanation of the facies distribution of the Ordovician Pingliang Formation along the southern margin of the Ordos Basin, China

, 2019
The Late Ordovician Pingliang Formation accumulated along the southern margin of the Ordos Basin in China. The convergence of the Yangtze Plate and Sino-Korean Plate led to a trench–arc–basin system during the Middle Ordovician, with a platform- and ...

New Permian Paleomagnetic and Geochronologic Results From the Alxa Block: Constraints on Its Tectonic Affinity and the Closure of Paleo‐Asian Ocean

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The Paleo‐Asian Ocean's (PAO) closure timing and the Alxa Block's (ALB) tectonic affinity remain debated. We present new paleomagnetic and geochronologic data from Permian volcanic and sedimentary rocks in the ALB. Characteristic remanent magnetization (ChRM) directions from Early (∼282 Ma), Middle (∼268 Ma), and Late Permian (∼255 Ma) rocks ...

A Comprehensive Crustal Coda Attenuation Map of Continental China

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Seismic coda wave attenuation (QC) reflects both intrinsic inelasticity and small‐scale heterogeneities in the Earth's crust, offering insights into its thermal state and structural complexity. Continental China, characterized by widespread plate boundary deformation, is among the most tectonically active regions globally.

DataSheet1_Vertical Slip Rates of Normal Faults Constrained by Both Fault Walls: A Case Study of the Hetao Fault System in Northern China.docx

, 2022
The slip rate is a fundamental kinematic parameter of active faults. Traditional methods using fault scarps or trenches may produce inaccurate estimates of a fault’s vertical slip rate.
