Negative Frictional Healing in Icelandic Geothermal (IDDP‐2) Core Samples: Potential Implications for Detachment‐Fault Mechanics

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Detachment faults in mid‐ocean ridge settings accommodate tectonic extension. These faults are potentially weakened by alteration through phyllosilicate‐ and amphibole‐mineral formation. Seven core samples taken from the Krafla and Reykjanes geothermal fields in Iceland allow for the study of the effect of mineral alteration on the frictional ...

Mineralogical and Geochemical Characteristics of Al-rich Clays from the Longqi Hydrothermal Field, Southwest Indian Ridge

open access: yesYankuang ceshi, 2018
BACKGROUND The mineralogy, chemistry and crystal structure of hydrothermal clay minerals from various geologic settings have been studied to reflect the fluid-rock interaction and physico-chemical evolution of fluids in hydrothermal environments. However,

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

open access: yesLand Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

Controls on tetrahedral Fe(III) abundance in 2:1 phyllosilicates—Discussion

open access: yes, 2021
International audienceCuadros et al. (2019) used a wide range of data from dioctahedral and trioctahedral Fe 3+-bearing 2:1 phyllosilicates, to propose a model describing how tetrahedral occupancy by Fe 3+ takes place in both dioctahedral and ...

Is selective identification of poorly crystalline aluminum hydroxides in soils of temperate latitude possible?

open access: yesSoil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Aluminum (Al) is one of the most abundant elements in soils. As poorly crystalline Al hydroxides are reactive toward soil organic matter (SOM), they are thought to be involved in SOM stabilization. This is also inferred from correlations between soil organic carbon contents and those of Al extracted by acid oxalate in darkness (AOD), although ...

Stacking faults with 180° layer rotation in celadonite, an fe- and mg-rich dioctahedral mica [PDF]

open access: yes, 2008
Stacking disorder in celadonite, a dioctahedral mica with Fe and Mg as major octahedral cations and which generally adopts the 1M stacking sequence, was investigated mainly by using transmission electron microscopy (TEM).

Response of yellow catfish (Pelteobagrus fulvidraco) to different dietary concentrations of aflatoxin B1 and evaluation of an aflatoxin binder in offsetting its negative effects

open access: yesCiencias Marinas, 2016
Aflatoxin B1 (AFB1), produced by Aspergillus flavus and Aspergillus parasiticus, is one of the major mycotoxins to affect animal health. AFB1 contamination of aquafeed is widespread, especially in countries with humid, tropical climates.
