Near Surface Geophysics, Volume 24, Issue 5, Page 669-692, October 2026.Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

, 2005 A new method of non-hydrofining is proposed to improve the stability of diesel fraction of Fushun shale oil. The experimental results show that solvent extraction is efficiently selective to remove nitrogen-, oxygen-, and sulfur-containing compounds.

Seismic Versus Sub‐Seismic Experimental Mirror‐Like Fault Surfaces in Bituminous Dolostones
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.Abstract Mirror‐like Surfaces (MSs) are ultra‐polished surfaces frequently found in exhumed seismogenic fault zones in carbonates. They form over a wide range of pressure‐temperature conditions and slip rates, from seismic (≈1 m/s) to sub‐seismic (≈0.1–100 μm/s), reflecting distinct phases of the seismic cycle.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Sedimentology, Volume 73, Issue 6, Page 2353-2380, October 2026.ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Sedimentology, Volume 73, Issue 6, Page 2417-2453, October 2026.ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin
Sedimentology, Volume 73, Issue 6, Page 2454-2487, October 2026.ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.
