  • Clays and Clay Minerals, Vol. 55, No. 1, 1–17, 2007. 
    Bishop, Janice L.; Schiffman, Peter; Murad, Enver; Dyar, M. Darby; Drief, Ahmed; Lane, Melissa D. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Altered basaltic tephra from Haleakala, Maui, are characterized using multiple techniques in order to identify the minerals formed under a variety of conditions and to understand the soil formation processes here. We ...
  • Clays and Clay Minerals, Vol. 56, No. 1, 10–22, 2008. 
    Gates, Will P. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    The assignments ofOH-bending bands in the infrared (IR) spectra ofdioctahe dral smectites (montmorillonites, ferruginous smectites, and nontronites) have been revisited using a cation mass-valence sum (CM-VS) approach to ...
  • Clays and Clay Minerals, Vol. 57, No. 2, 227–233, 2009. 
    Bzdek, Bryan R.; Mcguire, Molly M. (The Clay Minerals Society, 2009)
    Reductionof structural Fe insmectites affects the surface chemical behavior of the clay, but the underlying mechanism and changes in clay structure are still in need of investigation, particularly with respect to changes ...
  • Clays and Clay Minerals, Vol. 57, No. 4, 502–509, 2009. 
    Guegan, Regis; Gautier, Mathieu; Beny, Jean-Michel; Muller, Fabrice (The Clay Minerals Society, 2009)
    The transformation of clay minerals into organo-clays by surfactant intercalation is of great environmental and industrial importance because it causes the clay to attract hydrophobic contaminants and other non-polar organic ...
  • Clays and Clay Minerals, Vol. 59, No. 4, 359–377, 2011. 
    Ehlmann, Bethany L.; Mustard, John F.; Clark, Roger N.; Swayze, Gregg A.; Murchie, Scott L. (The Clay Minerals Society, 2011)
    The enhanced spatial and spectral resolution provided by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) on the Mars Reconnaissance Orbiter (MRO) has led to the discovery of numerous hydrated silicate ...
  • Clays and Clay Minerals, Vol. 60, No. 6, 655–665, 2012. 
    Ritz, Michal; Vaculikova, Lenka; Plevova, Eva; Matysek, Dalibor; Malis, Jiri (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    The objective of the present study was to determine the predominant minerals in sedimentary rocks using Fourier-transform infrared (FTIR) spectroscopy and chemometric analysis. The chemometric analysis was performed on ...
