  • Pestitschek, Brigitte; Gier, Susanne; Essa, Mahmoud; Kurzweil, Hans (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Recognizing weathering effects is significant for any work carried out on glauconites at the surface. The mineralogy and chemistry of glauconite grains exposed to weathering in a hot arid climate for a maximum of 42 y were ...
  • Kim, Jinwook; Furukawa, Yoko; Curry, Kenneth J.; Bennett, Richard H. (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Particle concentration, charge, solution chemistry (i.e. ionic strength), and the nature of organic matter (OM) are the major factors controlling particle flocculation in aqueous environments. In the present study, the ...
  • Jeong, Sueng Won; Locat, Jacques; Leroueil, Serge (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Particle-particle interactions in natural clays can be evaluated by their rheological behavior, but the results are often affected by the physicochemical properties of the clays. The behaviors of two fundamentally different ...
  • Gali, S.; Soler, J. M.; Proenza, J. A.; Lewis, J. F.; Cama, J.; Tauler, E. (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Garnierites represent significant Ni ore minerals in the many Ni-laterite deposits worldwide. The occurrence of a variety of garnierite minerals with variable Ni content poses questions about the conditions of their ...
  • Balko, Barbara A.; Bosse, Stephanie A.; Cade, Anne E.; Jones-landry, Elise F.; Amonette, James E.; Daschbach, John L. (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    The combination of zero-valent iron (ZVI) and a clay-type amendment is often observed to have a synergistic effect on the rate of reduction reactions. In the present study, electrochemical techniques were used to determine ...
