Analytical Methodology to Determine Thermally Induced Soil Deformation From Laboratory Data

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5868-5890, November 2026.
ABSTRACT Experimental laboratory investigations underlie most of the knowledge about the mechanics of soils under non‐isothermal conditions and their thermally induced deformation. Despite advances, the understanding of thermally induced deformation of soils remains inconsistent, hindering the development of a coherent framework that can advance ...

Dynamic role of "illite-like" clay minerals in temperate soils: facts and hypotheses

, 2007
Analysis of new data and reinterpretation of published information for clay minerals found in temperate climate soil profiles indicates that there is often a gradient of "illite-like" clay minerals with depth. We used the term "illite-like" because these

Investigating the flow behaviors of multi-component oil in shale nanopores via MD simulations

Frontiers in Earth Science
IntroductionShale reservoirs contain a substantial number of nanopores. When the pore size is at the nanoscale, the confinement effect exerts a significant influence on shale oil flow within the pores. The flow mechanisms of shale oil in nanopores remain

An Anisotropic Constitutive Model for Crushable Geomaterials Based on Non‐Stationary Critical State Line Concept

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5919-5935, November 2026.
ABSTRACT In this paper, the dependencies of granular soil behaviour on particle crushing and fabric anisotropy are formulated within a novel model based on bounding surface plasticity theory enriched by the non‐stationary critical state line (NCSL) concept.

Effect of salinity on rheological properties and structural stability of illite

Yantu gongcheng xuebao
The internal cause of changes in the physical and mechanical properties of soil is closely related to the microstructure of the particles. Rheology has been proved to be an effective way to study the viscoelasticity and microstructure stability of soil ...

Hydrothermal Sealing at Turrialba, Poás, and Rincón de la Vieja Volcanoes (Costa Rica) Promotes Phreatic and Phreatomagmatic Eruptions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Hydrothermal sealing is a mechanism thought to be responsible for challenging‐to‐forecast phreatic and phreatomagmatic eruptions. To better understand this process, we present a study in which we assessed the textural, mineralogical, and physical properties (porosity, permeability, and tensile strength) of blocks of hydrothermal seal that were

A new illite geothermometer

, 1988
Sericite, either as illite or illite/smectite, is ubiquitous in geothermal systems. Theoretical Ca- and Na-smectite contents of non-expanding geothermal sericites have been calculated from published electron microprobe analyses.

Formation mechanisms of illite, chlorite and mixed-layer illite-chlorite in Triassic volcanogenic sediments from the Southland Syncline, New Zealand [PDF]

, 1988
Clay minerals from the three principal kinds of zeolitic sediments from the type area for zeolite facies alteration, the Triassic Murihiku Supergroup, Southland, New Zealand, have been studied by TEM.

THERMOMECHANICAL ANALYSIS OF ILLITE FROM FÜZÉRRADVÁNY

Medžiagotyra, 2015
Young’s modulus of green illite from Füzérradvány (Hungary) was measured in-situ in the temperature interval 20 °C – 1100 °C and auxiliary analyses DTA, TG and TDA, XRD and EGA, were also performed.
