The Role of Randomly Mixed-Layered Chlorite/Smectite in the Transformation of Smectite to Chlorite [PDF]
Clays and Clay Minerals, 1997 AbstractVesicular and groundmass phyllosilicates in a hydrothermally altered basalt from the Point Sal ophiolite, California, have been studied using transmission electron microscopy (TEM). Pore-filling phyllosilicates are texturally characterized as having coherent, relatively thick and defect-free crystals of chlorite (14 Å) with occasional 24-Å ...

K-Ar dating by smectite extracted from bentonite formations [PDF]
E3S Web of Conferences, 2019 We attempt to apply K-Ar dating to extracted smectite from bentonite formations collected by different age formations from Japan, China, and America. The results show that the K-Ar ages of smectite are younger than the expected geological age estimated ...

Modification of smectite structure by sulfuric acid and characteristics of the modified smectite [PDF]
Journal of Agricultural Sciences (Belgrade), 2011 Bentonite samples from Petrovac and Aleksinac were treated with sulfuric acid of different molarities. Differences in structure and texture of the initial and modified bentonite were determined by chemical analysis and Xraypowder diffraction (XRPD ...

The fate of smectite in KOH solutions [PDF]
American Mineralogist, 2006 The aim of the present study was to investigate the detailed evolution of the SAz-1 smectite in 1 M KOH at 80 °C at a solid/liquid ratio of 1/80. AFM observations indicated no change in crystal size or shape. XRD measurements at 40% relative humidity revealed changes in expandability of the smectite. The (001) reflection profile of smectite was modeled

Brazilian clays for environmental solutions applied to radioactive waste management
Brazilian Journal of Radiation Sciences, 2021 Clays have been adopted in most nuclear waste producing countries as a key constituent in engineered barrier systems for final disposal facilities at all levels of radioactive wastes (LILW-SL, LILW-LL, and HLW).

A Comparative Study of the Properties of Mica in Rhizosphere and Bulk Soil Under Different Plant Covering. [PDF]
Al-Qadisiyah Journal For Agriculture Sciences, 2018 Results of x-ray diffractions for Bulk soil, represented by the horizontal distance 50H, show the presence of low-crystalline chlorite, smectite and regular interstratified chlorite- smectite in soil under Citrus aurantium trees.

T-2 toxin adsorption by hectorite [PDF]
Journal of the Serbian Chemical Society, 2009 The adsorption of T-2 toxin by the natural smectite mineral-hectorite at pH 3.0, 7.0 and 9.0 was investigated. The results of T-2 toxin adsorption on hectorite showed that the T-2 adsorption capacity decreased with increasing concentration of adsorbent ...
