Ostracodal evolution during the Permian–Triassic transition at the Youping section of the Nanpanjiang Basin

Frontiers in Ecology and Evolution, 2023
The Permian–Triassic mass extinction has been considered the largest bio-crisis of the Phanerozoic, with more than 90% of marine species extinct. Previous studies showed that ostracods suffered various extinction patterns in different localities and were

Study of the Corrosion Characteristics of Tunnel Fissures in a Karst Area in Southwest China

Geofluids, Volume 2018, Issue 1, 2018., 2018
The development of the fissures in soluble rock of karst areas directly affects the construction and operation safety of tunnel engineering. It is thus of theoretical and practical significance to study the characteristics of its corrosion and its influencing factors.

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.
