    Diagenetic kaolin minerals are very common in the Permo-Triassic succession from the SE Iberian Range, Spain. The morphology and crystal structure of kaolin minerals has been examined in four size fractions (<1 mm, <2 mm, ...
  • Hong, Hanlie; Li, Zhaohui; Xue, Huijuan; Zhu, Yunhai; Zhang, Kexin; Xiang, Shuyuan (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The clay mineral content of the Oligocene sediments in the Linxia Basin has been investigated using X-ray diffraction, scanning electron microscopy, and high-resolution transmission electron microscopy. The clay mineral ...
  • Aldega, Luca; Botti, Flavia; Corrado, Sveva (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Temperature-dependent clay mineral assemblages and vitrinite reflectance data have been used to investigate levels of diagenesis from the Messinian Laga Basin in the Central Apennines developed at the footwall of the ...
  • Dolinar, Bojana; Misˇicˇ, Miha; Trauner, Ludvik (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    As the water content is increased, the consistency of a fine-grained soil changes from a semisolid state to a plastic stateand finally to a liquid state. Thepl astic limit (PL) is thepoint at which the consistency, caused ...
  • Bascun˜an, Sophi´a; Kelm, Ursula; Sanhueza, Vilma; Alfaro, Guillermo (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Tuffs of the Tertiary Colbu´n Formation near Quinama´vida in central so uthern Chile have been mapped and their mineralogy analyzed. The pyroclastic rocks present a maximum outcropping thickness of 120 m and are dominated ...
  • Dogan, Meral; Dogan, A. Umran; Yesilyurt, F. Irem; Alaygut, Dogan; Buckner, Ira; Wurster, Dale Eric (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The Clay Minerals Society published a complete characterization scheme for its ‘Source Clays’ but not for its ‘Special Clays’. To address this issue, the specific surface areas (SSAs) of the 16 special clays from The Clay ...

  • Gionis, Vassilis; Kacandes, George H.; Kastritis, Ioannis D.; Chryssikos, Georgios D. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The octahedral composition of palygorskite in more than 300 samples from the Pefkaki deposit, W. Macedonia, Greece, has been studied by near-infrared (NIR) and X-ray diffraction (XRD), and evaluated according to the formula ...
  • 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 ...
