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 ...

Tectonic Fracture Characterization and Stress Analysis in Complex Fault Block Formations: A Case Study in the Second Member of Dengying Formation in Central Sichuan

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
The Dengying Formation within Pengtan 1 well area in the Sichuan Basin is a vital gas reservoir for exploration and development. The reservoir is situated in a complex fault block structure characterized by multistage fault evolution, leading to a complicated distribution of tectonic fractures crucial for the accumulation and migration of oil and gas ...

Origin and age of Mn deposits of the Nantuo Formation in the Sinian System

open access: yesChinese Science Bulletin, 1997
THE tillites in the Nantuo Formation of the Sinian System is considered contemporary with theVaranger ice age. The manganese deposits in the Nantuo Formation are most suitable to isotopic dating and may record the precious information on paleo-ocean chemistry.
