Controlling Factors of Organic Matter Enrichment in Marine–Continental Transitional Shale: A Case Study of the Upper Permian Longtan Formation, Northern Guizhou, China

The marine–continental transitional shale of the Upper Permian Longtan Formation in northern Guizhou is an important source rock in the upper Yangtze region of China, and it holds significant potential for the exploration of shale gas.

Salt Tectonics and Inversion Style in the Southeastern Iberian Chain

Tectonics, Volume 45, Issue 11, November 2026.
Abstract The southeastern Iberian Chain is characterized by Mesozoic rift basins that were subsequently inverted during Alpine contraction. We integrate geological mapping, borehole data, balanced cross‐sections, structural restoration, and forward kinematic modeling to evaluate how rift architecture controlled Alpine deformation from basin to crustal ...

Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

Stress Sensitivity Experiment on Shale Gas Formations in Marine-Continental Transitional Facies in Easten Margin of Ordos Basin

Zuanjingye yu wanjingye
The shale gas formations in the marine-continental transitional facies of the eastern margin of the Ordos Basin are tight gas formations with complex pore and fracture structures as well as high heterogeneity which result in special stress sensitivity of

Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

Basin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Spectral Analysis of Carboniferous Rhythmites Indicates Tidal Modulation and Marine Connectivity in the Cumberland Basin (Joggins Formation, Atlantic Canada)

Basin Research, Volume 38, Issue 6, November‐December 2026.
Statistically significant cyclicity preserved in Joggins Formation rhythmites is most consistent with tidal modulation. These findings provide new quantitative evidence that tidal energy propagated into the Cumberland Basin, supporting interpretations of marine connectivity during Late Carboniferous deposition.

Pore Structure and Heterogeneity Characteristics of Coal-Bearing Marine–Continental Transitional Shales from the Longtan Formation in the South Sichuan Basin, China

Marine–continental transitional shale has become a new field for shale gas exploration and development in recent years. Its reservoir characteristics analysis lags significantly behind that of marine shale, which restricts the theoretical research ...

Optimization and application of hydraulic fracture propagation in carbonaceous and siliceous shales of marine-continental transition facies

Meikuang Anquan
Aiming at the differences in mechanical properties of carbonaceous and siliceous shale rocks in transitional facies, a hydraulic fracturing model was established using the finite element ABAQUS numerical simulation software. The influence of lithological differences and fracturing parameters on the characteristics of hydraulic fracture propagation was ...

Enhanced Data-Driven Machine Learning Models for Predicting Total Organic Carbon in Marine–Continental Transitional Shale Reservoirs

Natural gas, as a sustainable and cleaner energy source, still holds a crucial position in the energy transition stage. In shale gas exploration, total organic carbon (TOC) content plays a crucial role, with log data proving beneficial in predicting ...
