  • Liu, Xiandong; Lu, Xiancai; Zhou, Huiqun; Xu, Shijin (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The structure and dynamics of alkylammonium-intercalated smectites were simulated using molecular dynamics employing the clayff-CVFF force field, the reliability of which was firstly validated for these systems. The layering ...
  • Cho, Yunchul; Komarneni, Sridhar (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The weathering stages of K-depleted biotite, K-depleted phlogopite, and natural biotite were investigated using hydrothermalt reatment with AlCl3 solution at 200ºC for 12 to 72 h. Although there were some differences in ...
  • Bentabol, Maria; Cruz, Maria Dolores Ruiz; Huertas, F. Javier (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Rapid dissolution of partly amorphized kaolinite in the systems kaolinite + NiCl2, kaolinite + Ni(OH)2, and kaolinite + NiCl2 + Ni(OH)2, at a temperature of 200ºC and at pH between 5.3 and 7.4, leads to the precipitation ...
  • Wise, Michael A. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    A new occurrence of berthierine has been found in the Pulsifer granitic pegmatite, near Auburn, Maine. Berthierine was found in miarolitic cavities (‘pockets’) as aggregates of radial platy crystals with albite, as ...
  • Cho, Yunchul; Komarneni, Sridhar (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The formation of hydroxylated phases was investigated using K-depleted biotite (Na-biotite) and K-depleted muscovite (Na-muscovite) under hydrothermal treatment with alkali (Li+, K+, NH4 +, Rb+ and Cs+), alkaline earth ...
  • Hashizume, Hideo; Theng, Benny K. G. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    We have investigated the adsorption of adenine, adenosine, ribose, and adenosine-5’-phosphate (5’-AMP) by allophane at pH 4, 6 and 8. Adenine, adenosine and ribose gave similar isotherms, i.e. adsorption increased regularly ...
  • Garci´a-romero, E.; Sua´rez, M.; Santare´n, J.; Alvarez, A. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The Allou Kagne (Senegal) deposit consists of different proportions of palygorskite and sepiolite, and these are associated with small quantities of quartz and X-ray amorphous silica as impurities. No pure palygorskite or ...
  • Skiba, Michał (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The processes of clay mineral formation were studied in seven podzol profiles developed on granitic regoliths in the Polish part of the Tatra Mountains. The selected profiles have similar parent material and macroscopically ...
  • Grathoff, Georg H.; Baham, John E.; Easterly, Heather R.; Gassman, Paul; Hugo, Richard C. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Floating, mixed-valent Fe films have been observed worldwide in wetlands, ferrous iron-rich seeps, and in seasonally reduced soils, but are usually misidentified as oil or biofilms. There has been little characterization ...

    We used high-resolution X-ray texture goniometry to quantify changes in the mm-scale orientation of phyllosilicate minerals in a suite of Paleogene mudstones from the Podhale Basin in southern Poland. The sample set covers ...
  • 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 ...
  • Velbel, Michael A.; Barker, William W. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Air-dried and high-pressure frozen/freeze-etched samples of clinopyroxene and smectite in a saprolitized clinopyroxenite from Koua Bocca, Ivory Coast, West Africa, were compared to characterize textures developed during ...
