Full‐Scale Pore Structure Characterization of the Late Permian Dalong Shale in Western Hubei, Southern China

Geofluids, Volume 2026, Issue 1, 2026.
The Late Permian Dalong Formation in western Hubei has recently been recognized as a promising target for shale gas development. However, the comprehensive characterization of its pore structure remains limited. To elucidate the pore system of the Dalong shale, an integrated experimental approach was applied to outcrop‐derived samples.

DataSheet1_Marine Paleoproductivity From the Last Glacial Maximum to the Holocene in the Southwestern Atlantic: A Coccolithophore Assemblage and Geochemical Proxy Perspective.docx

, 2022
In this study, we associated the variations in coccolithophore assemblages with the variability in major elements (Fe, Ca, and Ti) from the continental slope of the western South Atlantic by investigating two marine sediment cores (GL-824 and GL-1109) to

Pore Geometry and Its Influences on Methane Adsorption in Shale Gas Reservoirs: A Case Study of Longmaxi Shale in the Da’an Area, Chongqing, China

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Understanding pore structure and methane sorption (MS) in shale gas reservoirs is critical for accurately estimating gas‐in‐place and prospective natural gas resources. The Longmaxi Shale, a leading formation for deep shale gas development in China, faces challenges in its economic production due to its strong spatial heterogeneity, complex pore ...

Magnetic Mineral Assemblages of Diagenetically Reduced Sediments and Their Contributions to Paleomagnetic Signals

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract During early diagenesis of marine sediments, iron‐bearing minerals undergo a series of redox reactions until they reach equilibrium with reactive chemical components. Paleomagnetic records in the sediments subjected to severe diagenesis can be distorted or lost due to iron mineral dissolution, and hence these sediments were often excluded from

The Onset of Summer Drought on the Iberian Peninsula Following Pliocene Global Cooling

Paleoceanography and Paleoclimatology, Volume 40, Issue 10, October 2025.
Abstract The highly biodiverse Iberian Peninsula has winter‐dominated precipitation and summer drought. The onset of this modern climate regime, termed a Mediterranean‐Type Climate, began during the Late Pliocene–Early Pleistocene, concurrent with global cooling.
