Geosciences, 2020 The paper presents the results of a study on clay minerals and detrital material of biosiliceous rocks (Paleocene–Eocene) from three sections in the Transuralian region. The authigenic processes in sediments resulted in the formation of dioctahedral clay

Coloration Technology, EarlyView.Abstract Textile wet processing generates dye‐containing effluents that require effective recovery and valorisation strategies. Halloysite nanoclay was used to capture Reactive Red 195 from a model aqueous solution, and the resulting dye‐loaded solid (REDHA7) was subsequently applied once to cotton by exhaustion dyeing and pigment‐type printing ...

Trioctahedral entities in palygorskite: Near-infrared evidence for sepiolite-palygorskite polysomatism [PDF]
, 2011 The mixed dioctahedral-trioctahedral character of Mg-rich palygorskite has been previously described by the formula yMg5 Si8 O20(OH)2(OH2)4(1–y)[xMg2Fe2(1–x)Mg2 Al2] Si8 O20(OH)2(OH2)4, where y is the trioctahedral fraction of this two-chain ribbon ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Ab initio calculations of relative stabilities of different structural arrangements in dioctahedral phyllosilicates [PDF]
, 2007 An ab initio theoretical approach has been used to calculate optimized geometries and the relative energies of various compositional arrangements in structures of dioctahedral smectites based on models consisting of two unit-cells.

Аbout use of ancient weathering crusts formation during diamond-prospecting works
Мінеральні ресурси України, 2021 Complex research of Late Devonian – Early Carboniferous and Middle-Late Triassic weathering crusts on various rocks (terrigenous-carbonate formations, dolerites, tuffs, tuffaceous formations and kimberlites) indicated that in conditions of warm and humid

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
