Timing of the initiation and duration of the Cretaceous extensional regime in South‐east China: Constraints from growth strata in terrigenous basins

The Depositional Record, Volume 10, Issue 1, Page 4-32, February 2024.
In the Cretaceous half‐graben basins of south‐east China, the variation of dip angles and thickness of red beds shapes four types of extensional growth strata. The rollback of the Palaeo‐Pacific plate results in the half‐graben and the NW‐SE extensional stress field which begins at ca 140 to 137 Ma in the South‐eastern China Block and lasts until the ...

Strike-Slip Pull-Apart Process of the Jiyang Depression during the Yanshanian Tectonic Cycle and Its Response to Paleo-Pacific Plate Movement

Abstract The Yanshanian tectonic evolution of the Jiyang Depression was complex in Jurassic and Cretaceous, making it difficult to pin down the tectonic regime of that time. This study compared fault activity, lithology, and sedimentary-facies patterns across the depression using 3D seismic volumes, borehole data, and sedimentary facies

Mechanisms of helium differential enrichment and helium‐nitrogen coupling: A case study from the Weiyuan and Anyue gas fields, Sichuan Basin, China

Geological Journal, Volume 59, Issue 1, Page 272-287, January 2024.
The uplift of the basement granite was crucial for the exsolution and enrichment of dissolved helium, and it was also the main reason for He–N2 coupling. The differential uplift that occurred in the Leshan–Longnvsi palaeo‐uplift during the Himalayan period further promoted the differential enrichment of He resources, thus also impacting the N2/He ratio

Logging Response Mechanism and Content Evaluation of Laumontite‐Bearing Glutenite Reservoir: A Case Study of Lower Urho Formation of Permian of the Junggar Basin

Geofluids, Volume 2024, Issue 1, 2024.
The Urho Formation in the Lower Permian System at the Junggar Basin in China commonly develops zeolite cements. The presence of zeolite minerals in various states of occurrence and uneven distribution in glutenite reservoirs makes it indeterminate to interpret the well logging response characteristics such as acoustic, resistivity, radioactivity, and ...
