  • Proust, D.; Caillaud, J.; Fontaine, C. (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    The early stages of amphibole weathering result in the crystallization of several clay mineral species: tri- and dioctahedral smectites, interstratified dioctahedral kaolinite-smectite (K-S), and halloysite. Each clay ...
  • Joussein, Emmanuel; Petit, Sabine; Fialips, Claire-Isabelle; Vieillard, Philippe; Righi, Dominique (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    Two reference halloysites from New Zealand (Te Puke and Opotiki) were studied by X-ray diffraction under (1) various levels of relative humidity (RH) from 95 to 0% (dehydration), and (2) various temperatures increasing ...
  • Fisher, G. Burch; Ryan, Peter C. (The Clay Minerals SocietyThe Clay Minerals Society, 2006-09)
    Soils developed on Quaternary fluvial fill terraces in the humid tropics of Costa Rica display progressive changes in mineral assemblage, chemical composition and particle size with age. Clay minerals from B horizons of ...
  • Matusik, Jakub; Gaweł, Adam; Bielanska, Elzbieta; Osuch, Władysław; Bahranowski, Krzysztof (The Clay Minerals Society, 2009)
    Kaolin-group clay minerals can be modified to form nanotubular and mesoporous structures with interesting catalytic properties, but knowledge of the best methods for preparing these structures is still incomplete. The ...
  • Papoulis, Dimitrios; Tsolis-Katagas, Panagiota; Kalampounias, Angelos G.; Tsikouras, Basilios (The Clay Minerals Society, 2009)
    Occurrences of halloysite-rich material in altered volcanic rocks, principally trachyandesites, dacites, and tuffs, extend over an area of ~1 km2 in the southwestern part of Limnos, Island, northeast Aegean Sea, Greece. ...
  • Matusik, Jakub; Wisła-Walsh, Ewa; Gaweł, Adam; Bielanska, Elzbieta; Bahranowski, Krzysztof (The Clay Minerals Society, 2011)
    Mesoporous materials with pore diameters in the range 2-50 nm forming tubular or fibrous structures are of great interest due to their unique properties. Because they are commonly used as sorbents and catalyst carriers, ...
