Drainage Divide Migration in Response to Asymmetric Uplift at Eastern Qinling, China

open access: yesTerra Nova, EarlyView.
ABSTRACT Drainage divide migration shapes landscape, sediment patterns, and biodiversity, which is affected by a variety of factors. While geomorphic index and numerical simulations have been employed to investigate divide migration, previous studies ignore the present‐day vertical velocity field.

Is the Jurassic (Yanshanian) intraplate tectonics of North China due to westward indentation of the North China block? [PDF]

open access: yes, 2012
International audienceThe northern mountains of Beijing are the type locality of the Mesozoic Yanshanian orogen. Our structural study emphasizes the importance of dextral strike-slip for the formation of this intracontinental belt.

Crustal structure and deformation beneath the NE margin of the Tibetan plateau constrained by teleseismic receiver function data [PDF]

open access: yes, 2015
We analysed a large amount of teleseismic receiver function data recorded by 172 broadband stations in the NE Tibetan plateau and its surrounding areas to investigate the crustal velocity and anisotropy structure beneath the margin.

Numerical Simulation of Deep Coalbed Methane Development Based on Embedded Discrete Fracture Model: A Triple Medium Flow Approach

open access: yesEnergy Science &Engineering, Volume 13, Issue 6, Page 3045-3062, June 2025.
ABSTRACT China is rich in coalbed methane resources, especially with significant potential for deep coalbed methane development. As shallow coalbed methane resources gradually deplete, the development of deep coalbed methane has become a research focus.

Mechanical Properties and Energy Characteristics of Shales Under Conventional Triaxial Compression Conditions Based on Different Initial Prestresses

open access: yesEnergy Science &Engineering, Volume 13, Issue 5, Page 2364-2374, May 2025.
Mechanical properties and energy characteristics of shales. ABSTRACT Conventional triaxial compression tests were conducted on shale specimens under varying initial prestress conditions to investigate their mechanical properties and energy evolution characteristics, thereby revealing the shale damage mechanism.

Carbon isotopic signature of coal-derived methane emissions to the atmosphere: from coalification to alteration [PDF]

open access: yes, 2016
Currently, the atmospheric methane burden is rising rapidly, but the extent to which shifts in coal production contribute to this rise is not known.

Carbon and Hydrogen Isotopic Reversals in Highly Mature Coal-Derived Gases: A Case Study of Paleozoic Gases in the Southern Ordos Basin, China

open access: yesGeofluids, 2019
The compositional carbon isotopic series δ13C-CH42.4%. Where 2.4%>Ro>2.0%, almost all gases display partial isotopic reversal, with δ13C-CH4>δ13C-C2H6 or δ13C-C2H6>δ13C-C3H8. Carbon isotopic reversal in coal-derived gases is not caused by abiotic origin,

A feasibility study of geological CO2 sequestration in the Ordos Basin, China

open access: yesEnergy Procedia, 2011
AbstractThe Shaanxi Province/Wyoming CCS Partnership (supported by DOE NETL) aims to store commercial quantities of CO2 safely and permanently in the Ordovician Majiagou Formation in the northern Ordos Basin, Shaanxi Province, China. This objective is imperative because at present, six coal-to-liquid facilities in Shaanxi Province are capturing and ...
