  • Breiner, Joan M.; Anderson, Michael A.; Tom, Harry W.K.; Graham, Robert C. (The Clay Minerals Society, 2006)
    Abstract -- The reactivity of colloidal particles is regulated by their surface properties. These properties affect the wettability, flocculation-dispersion characteristics, ion exchange, sorption capacities and transport ...
  • Dogan, A. Umran; Dogan, Meral; Onal, Muserref; Sarikaya, Yuksel; Aburub, Aktham; Wurster, Dale Eric (The Clay Minerals SocietyThe Clay Minerals Society, 2006)
    Specific surface area measurements of The Clay Minerals Society source clays were made by the Brunauer, Emmett and Teller (BET) method of adsorption of nitrogen gas. Two replicate measurements of specific surface area were ...
  • Varadachari, Chandrika (The Clay Minerals SocietyThe Clay Minerals Society, 2006-09)
    This paper presents a novel concept in the thermodynamic derivation of phase diagrams for clay minerals that incorporates fuzzy transition zones. This new technique yields phase diagrams that have graded (fuzzy) zones of ...
  • Balan, Etienne; Fritsch, Emmanuel; Allard, Thierry; Calas, Georges (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The tropical weathering of sedimentary kaolin deposits from the plateaux surrounding Manaus (Alter do Chao formation, Amazon basin, Brazil) leads to the in situ formation of thick kaolinitic soils. The structural changes ...
  • Bobos, Iuliu; Vieillard, Philippe; Charoy, Bernard; Noronha, Fernando (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The alteration of spodumene to cookeite has been identified in a Li-bearing aplite-pegmatite from northern Portugal. Optical microscopy and scanning and transmission electron microscopy (SEM/ TEM) were used to characterize ...
  • Marti´n-marti´n, J. D.; Go´mez-gras, D.; Sanfeliu, T.; Thiry, M.; Ruiz-cruz, M. D.; Franco, F. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    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, ...
  • 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 ...
  • Letaief, Sadok; Detellier, Christian (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Ionic liquids intercalated in kaolinite constitute a novel class of nanostructured material. Kaolinite-pyrrolidinium halide intercalates have been prepared successfully by reacting the pyrrolidinium salts with kaolinite ...
  • Cochiara, Stacey G.; Phillips, Brian L. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Using 19F magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy, we show that most of the fluoride present in the KGa-1b reference kaolinite from Washington County, Georgia, occurs as a surface-adsorbed ...
  • Wenk, H.-r.; Voltolini, M.; Mazurek, M.; Van Loon, L. R.; Vinsot, A. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Anisotropy in clay-rich sedimentary rocks is receiving increasing attention. Seismic anisotropy is essential in the prospecting for petroleum deposits. Anisotropy of diffusion has become relevant for environmental contaminants, ...
  • Gurel, Ali; Kadir, Selahattin (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Late Miocene clayey sediments were deposited in lake-margin and shallow-lake environments of the southeastern Central Anatolian Volcanic Province (CAVP). Yellow to red mudstone, alternating with thin beds of conglomerate ...
  • Johnston, Cliff T.; Kogel, Jessica Elzea; Bish, David L.; Kogure, Toshihiro; Murray, Haydn H. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Low-temperature FTIR spectroscopy was used to characterize the n(OH) region of kaolingroup minerals including well ordered to poorly ordered kaolins from Georgia, Brazil, and England, along with samples of discrete dickite ...
  • Palomino, Angelica M.; Burns, Susan E.; Santamarina, J. Carlos (The Clay Mineral SocietyThe Clay Minerals Society, 2008)
    The behavior of mineral mixtures can be significantly different from the behavior of the individual components of the mixture due to differences between the mechanical and chemical properties of the individual minerals, ...
  • Lindgreen, Holger; Drits, Victor A.; Jakobsen, Finn C.; Sakharov, Boris A. (The Clay Minerals SocietyThe Clay Minerals Society, 2008)
    Upper Cretaceous-Danian chalk and interbedded clay-rich layers from wells of the South Arne Field and adjacent wells in the North Sea and from Stevns in Zealand have been investigated to determine the clay mineralogy in ...
  • Pardo, Pablo; Bastida, Joaquin; Serrano, Francisco J.; Ibanez, Rafael; Kojdecki, Marek A. (The Clay Minerals SocietyThe Clay Minerals Society, 2009)
    Abstract-Due to the great technological importance of the microstructure of kaolinite, characterizing its evolution during dry milling of kaolin and analyzing the microstructural information obtained from different methods ...
  • Scholtzova, Eva; Smrcok, L’ubomir (The Clay Minerals Society, 2009)
    The aims of this study were to obtain accurate structural information on the dimethyl sulfoxide (DMSO) and dimethylselenoxide (DMSeO) kaolinite intercalates, paying close attention to the hydrogenbond geometries, and to ...
  • Sengupta, Aniruddha (The Clay Minerals Society, 2009)
    The potential for structural failure of consolidated clay materials, which is of great importance in many applications, typically are assessed by measuring the localized strain bands that develop under anisotropic load ...
  • Mantovani, Marco; Escudero, Alberto; Becerro, Ana Isabel (The Clay Minerals Society, 2009)
    Understanding the mechanisms for illitization of clay minerals has important applications in reconstructing geologic histories and determining the origins of physical and chemical characteristics of buried sediments. While ...
  • Kadir, Selahattin; Kart, Firdevs (The Clay Minerals Society, 2009)
    The Sogut kaolinite deposits at C¸ altı, I˙nhisar, and Kure, Turkey, are an important source of raw materials for the ceramics industry of that country, but no detailed mineralogical or geochemical characterizations 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 ...
