Two Distinct Growth Styles of Riedel Shear Zones in Cratonic Strike‐Slip Fault System, Tarim Basin, NW China

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

A reservoir rock wettability modifier for ultra-high temperature and high salinity environment

Energy Geoscience
During drilling process, the water phase in drilling fluids infiltrates rock fractures through capillary action. The surface wettability of dolomite is governed by multiple factors, resulting in an unstable wetting state. Studies have shown that altering

Exsolution, Evolution, and Hysteresis of CO2 Nanobubbles in Water‐Saturated Sandstone

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Understanding CO2 nanobubble formation in water‐saturated sandstone is critical for understanding fluid behavior in CO2 storage systems. Here, CO2 exsolution from an aqueous phase in a sandstone was investigated using small‐angle neutron scattering at 50°C during cyclic depressurization from 12 to 0.7 MPa.

Are Time and Temperature the Simple Answer to the Dolomite Problem?

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Dolomite is among the most common carbonate minerals in ancient rocks but its formation is rarely observed today, a longstanding puzzle known as the “Dolomite Problem.” Recent advances in experimental mineralogy, geochemistry, and global abundance reconstructions have begun to resolve this problem.
