    Altered basaltic tephra from Haleakala, Maui, are characterized using multiple techniques in order to identify the minerals formed under a variety of conditions and to understand the soil formation processes here. We ...
  • Ucha, Vladimi´r Sˇ; Uhli´k, Peter; Madejova´, Jana; Petit, Sabine; Kraus, Ivan; Kelova´, L’ubica Pusˇ (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Abstract—Mixed-layer illite-smectite with high degree of ordering (rectorite-like clay) and with three types of interlayer cations - K+, Na+ and NH4 +, was determined in the high-sulfide epithermal mineralization of the ...
  • Drits, Victor A.; Mccarty, Douglas K. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Thermogravimetric analysis combined with mass spectrometry was used to study H2O bound to samples of illite-1M, illite-2M2 and leucophyllite-1M. Samples were heated in a helium atmosphere at different temperatures and after ...
  • Labuda, Ewa; Cherepakhov, Galina; Barkatt, Aaron (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The formation of hard hematite in steam generators with relatively high levels (5-10 mg/L) of dissolved oxygen at temperatures around 280-290ºC and pressures around 6-8 MPa can serve as an analog for the formation of hard ...
  • Saha, Uttam Kumar; Kozak, L. M.; Huang, P. M. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The citrate-induced desorption kinetics of pre-adsorbed Se from montmorillonite (Mt) and its complexes with hydroxyaluminum (HyA-Mt) and hydroxyaluminosilicate (HAS-Mt) were studied. The mole fraction of pre-adsorbed Se ...
  • Jaisi, Deb P.; Dong, Hailiang; Kim, Jinwook; He, Ziqi; Morton, John P. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Clay particle aggregation affects a number of environmental processes, such as contaminant sorption/desorption, particle movement/deposition, and sediment structure and stability, yet factors that control clay aggregation ...
  • Teppen, Brian J.; Aggarwal, Vaneet (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    The selectivities of clay minerals for larger organic cations over smaller ones have been attributed to favorable clay-organic interactions in clay interlayers and to hydrophobic effects resulting from (partial) dehydration ...
  • Slade, Phil G.; Gates, Will P. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    X-ray diffraction shows that ordered interlayer structures form when high-charged Llano vermiculite is reacted with HDTMA-Br or HDTMA-acetate, but the structures differ from those given by low-charged vermiculites. The ...
