Fe–Mn Crust δ98Mo Decline Records Tectonic Forcing on Marine Oxide Sink Reduction During the Early Eocene–Early Oligocene

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract S, Tl, and W isotope records document pronounced early Eocene shifts in marine redox, yet the absence of a Mo isotope record obscures its progression. Here, we present ∼80 Myr Mo–Os–Be–Nd isotope profiles from a Northwest Pacific hydrogenetic Fe–Mn crust, revealing a systematic δ98Mo decline from −0.24‰ (early Eocene) to −0.83‰ (early ...

Constraining the Relative Chronology of Repeated Large Earthquakes in the Longmen Shan Thrust Belt, Eastern Tibetan Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...

Controlling factors of low resistivity in deep shale and their implications on adsorbed gas content: a case study in the luzhou area

open access: yesScientific Reports
Numerous gas-rich, low resistivity shale wells have been discovered in the Luzhou deep shale gas of Sichuan Basin, providing strong evidence that low-resistivity shale also holds significant potential for shale gas exploration. However, existing research

Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta

open access: yesTectonics
AbstractBased on the interpretation of a large seismic data set, we provide a comprehensive description of the structures affecting the entire Niger Delta, from the onshore domain to the deep‐offshore. The shale‐dominated delta lies on a divergent segment of the west African passive margin.

Experimental study on the influence of external fluids on the pore structure of carbonaceous shale

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Shale reservoirs have complex mineral compositions and are rich in micro-scale pores. It is of great scientific and engineering significance to explore the mechanism of external fluids on the pore throat structure of shale.
