  • Srodon, Jan; Zeelmaekers, Edwin; Derkowski, Arkadiusz (The Clay Minerals Society, 2009)
    The nature of component layers of mixed-layer illite-smectite and their possible evolution in the course of illitization have been debated since the 1960s. The present study is a new attempt to solve these problems, using ...
  • Dohrmann, R.; Ruping, K.B.; Kleber, M.; Ufer, K.; Jahn, R. (The Clay Minerals Society, 2009)
    In X-ray diffraction (XRD) analysis, preparation of oriented clay specimens enhances their 00l reflections by arranging basal surfaces parallel to the specimen surface. In one-dimensional modeling of XRD intensities, degree ...
  • Landers, Matthew; Gilkes, Robert J.; Wells, Martin A. (The Clay Minerals Society, 2009)
    Abstract—A method for extracting Ni and other metals from lateritic ores by means of shock heating has been investigated. Shock heating releases some of the metal from its goethitic host. Even though the transformation of ...
  • Xi, Yuanzhou; Davis, Robert J. (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Glycerol is a byproduct of biodiesel synthesis by transesterification of triglycerides with shortchain alcohols in the presence of solid base catalysts. Because hydrotalcite is a potentially useful basic catalyst for the ...
  • Mantovani, Marco; Becerro, Ana Isabel (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    Studies of the paragenesis of authigenic illite in arkosic sandstones of various regions and ages have revealed that the illitization of kaolinite is an important reaction accounting for the formation of authigenic illite ...
  • Supronowicz, Wojciech; Roessner, Frank (The Clay Minerals Society, 2011)
    Hydrothermal syntheses of a silicate structure comprising a single tetrahedral layer, known as ilerite, were conducted in the presence of tin (SnCl4·5H2O) as a heteroatom. The main aim of the study was to investigate the ...
  • Supronowicz, Wojciech; Roessner, Frank; Schwieger, Wilhelm; Meilikhov, Mikhail; Esken, Daniel (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Hydrothermal syntheses of the magadiite, a layered silicate structure, were conducted in the presence of a heteroatom source (SnCl4 · 5H2O) with the intention of investigating its influence on the resulting material, as ...
  • Miller, Matthew A.; Madden, Andrew S.; Madden, Megan Elwood; Elmore, R. Douglas (The Clay Minerals SocietyThe Clay Minerals Society, 2012)
    Nontronite NAu-1 was exposed to moderate temperature and pressure conditions (250 and 300ºC at 100 MPa pressure) in KCl brine to simulate burial diagenetic systems over accelerated time periods appropriate for laboratory ...
  • Bishop, Janice L.; Rampe, Elizabeth B.; Bish, David L.; Abidin, Zaenal; Baker, Leslie L.; Matsue, Naoto; Henmi, Teruo (The Clay Minerals Society, 2013)
    Allophane and imogolite are common alteration products of volcanic materials. Natural and synthetic allophanes and imogolites were characterized in the present study in order to clarify the shortrange order of these materials ...
  • Komlo´si, Andrea; Kuzmann, Erno˝; Nagy, Noe´mi M.; Homonnay, Zolta´n; Kubuki, Shiro; Ko´nya, Jo´zsef (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The effect of FeCl3 in acetonic medium on the structure of Na-bentonite was studied using X-ray diffraction (XRD), 57Fe Mo¨ ssbauer spectroscopy, X-ray fluorescence spectroscopy and infrared spectroscopy to describe the ...
