Epidote Records (De)hydration From the Seafloor Through Subduction and Underplating: Implications for Subduction Zone Fluid Budgets and Slow Slip

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract When, where, and how much fluid is released from subducting oceanic crust control deformation, element cycling, and magmatism in subduction zones. However, the palimpsest of tectonometamorphic processes in the exhumed rock record complicates the relation of geologic observations to geodynamic models of subduction fluid sources and transport ...

The Effect of Temperature and Physical State of Water on the Frictional Properties of Chlorite‐Altered Basaltic Gouges (Krafla Geothermal Field, Iceland)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

The reaction kinetics of laumontite under hydrothermal conditions

European Journal of Mineralogy, 1993
Quantification of the rate of mass transfer in diagenetic and hydrothermal systems requires a knowledge of the kinetics of mineral-fluid reactions at elevated temperature and pressure and at chemical conditions close to equilibrium. This communication describes an experimental study of the reaction kinetics of laumontite, a Ca-zeolite, at 80, 120 and ...

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

Aligned hydrothermal fluid‐flow pathways in Middle Permian near‐shore marine sediments beneath a basaltic lava flow

Sedimentology, Volume 73, Issue 1, Page 83-102, January 2026.
ABSTRACT Tubular and curviplanar structures, outlined by the occurrence of haematite/goethite, chlorite, quartz and albite, are developed in the Middle Permian Broughton Formation in the southern Sydney Basin, New South Wales, Australia. These structures are interpreted as fluid‐flow pathways resulting from the ejection of heated pore fluids as a thick

Seismic Rock Physics Inversion With Varying Pore Structure Parameters and Consolidation Parameter in Tight Sandstone Reservoirs

Geofluids, Volume 2026, Issue 1, 2026.
Tight sandstone gas holds significant exploration and development potential. However, its complex pore structure and heterogeneous consolidation make quantitative reservoir prediction challenging. In this study, we propose a novel seismic inversion method that incorporates consolidation parameter and pore structure parameters as constraints for ...

Adsorptive Elimination of Heavy Metal Ions From Wastewater Utilizing Natural and Synthetic Zeolites: Mechanistic Analysis, Modification Techniques, and Performance Assessment

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Heavy metal contamination in wastewater remains a critical environmental challenge due to the persistence and toxicity of metal ions such as Pb2+, Cd2+, Cr3+/Cr6+, Cu2+, Ni2+, and Zn2+. Although conventional treatment technologies can achieve high removal efficiencies, their practical application is often limited by high operational costs, energy ...
