Characteristics and main controlling factors of the marlstone reservoirs of the first member of Permian Maokou Formatin in Weiyuan area, southern Sichuan Basin

Shiyou shiyan dizhi
The exploration of the first member of Permian Maokou Formation (Maokou 1) in the Weiyuan area of southern Sichuan Basin has been limited. Previous analyses of cast thin sections and argon ion electron microscopy based on earlier drilling data suggested ...

Effects of Periodic Normal Stress Oscillations on Frictional Properties of Simulated Natural Fault Gouges Under In Situ P‐T Conditions

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Induced earthquakes are occasionally associated with stress oscillations resulting from periodic industrial activities. Yet, the effects of stress oscillations on fault friction under realistic subsurface conditions are not fully clear. We conducted normal stress oscillations experiments using simulated fault gouges derived from the major ...

Decoding the Emeishan Permian mantle plume in the southeastern margin of Tibet from the seismic signature of the local lithosphere [PDF]

, 2022
The Emeishan large igneous province (ELIP), which is located along the southeastern margin of Tibet, is widely regarded as the erosional remnants of voluminous Permian mafic volcanic successions that were associated with mantle plume activity.

Biological and Ecological Characteristics of Fish in the Downstream Area of the Mamaya Hydropower Station and Reservoir Section of the Dongqing Hydropower Station on the Beipan River, China

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
As key indicator species for aquatic ecosystem health under cascade hydropower development, shifts in fish diversity directly reflect the cumulative impacts of hydropower projects on river connectivity, hydrological regimes, and habitat integrity, providing critical evidence for assessing ecological equilibrium and formulating conservation strategies ...

Anatomy of the Emeishan Mantle Plume Head: Insights From New Geochronologic, Geochemical, and Geologic Data

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 9, September 2024.
Abstract The link between mantle plumes and the formation of large igneous provinces (LIPs) is well established although the anatomy of these remains equivocal. Recent experimental studies and geophysical data suggest that the mantle plume head is more likely to be irregular and asymmetric, rather than an axisymmetric flattened disk. The Emeishan large

Permian (Artinskian to Wuchapingian) conodont biostratigraphy in the Tiegiao section, Laibin area, South China [PDF]

, 2016
Permian strata from the Tieqiao section (Jiangnan Basin, South China) contain several distinctive conodont assemblages. Early Permian (Cisuralian) assemblages are dominated by the genera Sweetognathus, Pseudosweetognathus and Hindeodus with rare ...

Mantle Plume‐Lithosphere Interactions Beneath the Emeishan Large Igneous Province

Geophysical Research Letters, Volume 51, Issue 2, 28 January 2024.
Abstract The formation of large igneous provinces (LIPs) has been widely believed to be linked to mantle plume activity. However, how the plume modifies the overlying lithosphere, particularly its compositional structure, remains uncertain. Here, we characterize the deep thermochemical structure beneath the Emeishan LIP (ELIP), which is a well‐known ...
