The Near-Infrared Combination Band Frequencies of Dioctahedral Smectites, Micas, and Illites
Al content Dioctahedral smectites Micas NIR spectra
2011/12/30
The highest frequency near-infrared (NIR) combination bands for specimens of four species of mica—montmorillonite-beidellite, illite, chlorite, and kaolinite—were correlated with respect to Al2O3 cont...
X-Ray Identification of One-Layer Illite Varieties: Application to the Study of Illites around Uranium Deposits of Canada
Hydrothermal alteration Illite Octahedral cation distribution Polytype Uranium deposits Vacant cis-sites Vacant trans-sites
2011/12/29
Structural and diffraction criteria for distinguishing between t-1M, c-1M, m-1M, and 3T illite varieties are described. The t-1M illite corresponds to a one-layer monoclinic structure with vacant tran...
Solubility Measurements of Phases in Three Illites
Equilibration Illite Kaolinite Phase analysis Pyrophyllite Solubility
2012/2/2
Goose Lake, Beavers Bend, and Fithian illites were equilibrated in the presence of goethite (or hematite) at room temperature for as long as 2.6 yr. Kaolinite of known stability was added to some samp...
Activity/Composition Relations among Silicates and Aqueous Solutions: II. Chemical and Thermodynamic Consequences of Ideal Mixing of Atoms on Homological Sites in Montmorillonites, Illites, and Mixed-Layer Clays
Activity Atom mixing Illite Mixed layers Montmorillonite Thermodynamics
2012/2/6
The activities of thermodynamic components of clay minerals corresponding in composition to pyrophyllite, muscovite, paragonite, and margarite were computed from chemical analyses reported in the lite...
Natural Ammonium Illites from Black Shales Hosting a Stratiform Base Metal Deposit, DeLong Mountains, Northern Alaska
Ammonium Black shale Illite Infrared spectroscopy Nitrogen X-ray powder diffraction
2012/2/7
Naturally occurring ammonium illites have been discovered in black shales surrounding a stratiform base metal deposit in the DeLong Mountains, northern Alaska. Infrared spectra of the samples exhibit ...
Boron Fixation by Illites
Boron Fixation Illites
2012/2/21
The mechanism of boron uptake by clays, especially illitic clays, and the factors which control such uptake have long been debated issues. In an attempt to answer some of the questions of the controve...
