Geochemical Constraints on the Generation of Coalbed Methane in the Weizhou Area, South‐Central Ningxia, NW China: Insights From Stable Isotopes and Organic Petrology

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Amid growing global clean energy demand, coalbed methane (CBM) in the coal‐rich Weizhou area holds great development value. This study explores Weizhou CBM′s geochemical traits and genesis via analyzing gas compositions (Shanxi and Taiyuan Formations), stable isotopic distributions (δ13C1, δD, δ13CO2, and δ15N), and their burial depth variations ...

Breedon Hill [PDF]

open access: yes, 2013
Breedon Hill forms one of the most prominent features in the landscape of north-west Leicestershire, standing up 50 m above the surrounding ground. That it has been a major landmark throughout recorded history is suggested by its name, which is derived ...

The Controlling Effect of Synsedimentary Normal Faults on Regional Gas Occurrence

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Taking the Guodishan Fault as an example, the regional geological evolution background and measured gas parameters were analyzed, and the gas occurrence characteristics in the region and the control effect of synsedimentary faults on regional gas were studied.

Simulation of the Liquid–Solid Coupling in the Distribution Law of Water‐Conducted Fractures in Weakly Cemented Overburden Strata as Exemplified by Daliuta Coal Mine in Western China

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
Based on the engineering background of the Daliuta mining area, the distribution of fractures and movement of water within weakly cemented overlying strata were studied with a physical simulation of liquid–solid coupling and a COMSOL numerical simulation test.
