  • Clays and Clay Minerals, Vol. 55, No. 1, 108–114, 2007. 
    Gimsing, Anne Louise; Borggaard, Ole Kragholm (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Adsorption by synthetic 2-line ferrihydrite and hematite of glyphosate and phosphate, separately and together, was compared with adsorption results for goethite, gibbsite and two kaolinites in order to determine adsorption ...
  • Clays and Clay Minerals, Vol. 55, No. 1, 59–70, 2007. 
    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 ...
  • Clays and Clay Minerals, Vol. 55, No. 6, 635–643, 2007. 
    Grathoff, Georg H.; Baham, John E.; Easterly, Heather R.; Gassman, Paul; Hugo, Richard C. (The Clay Minerals SocietyThe Clay Minerals Society, 2007)
    Floating, mixed-valent Fe films have been observed worldwide in wetlands, ferrous iron-rich seeps, and in seasonally reduced soils, but are usually misidentified as oil or biofilms. There has been little characterization ...
  • Clays and Clay Minerals, Vol. 57, No. 1, 46–53, 2009. 
    Cabello, E.; Morales, M. P.; Serna, C. J.; Barron, V.; Torrent, J. (The Clay Minerals SocietyThe Clay Minerals Society, 2009)
    Abstract—Soil formation usually results in an increase in magnetic susceptibility. The magnetic properties of the products of transformation of ferrihydrite, a typical precursor of other soil Fe oxides, were examined in ...
  • Clays and Clay Minerals, Vol. 58, No. 6, 772–782, 2010. 
    Baker, Leslie L.; Strawn, Daniel G.; Vaughan, Karen L.; Mcdaniel, Paul A (The Clay Minerals SocietyThe Clay Minerals Society, 2010)
    The characterization of poorly crystalline minerals formed by weathering is difficult using conventional techniques. The objective of this study was to use cutting-edge spectroscopic techniques to characterize secondary ...
  • Clays and Clay Minerals, Vol. 61, No. 1, 11–25, 2013. 
    Bolanz, Ralph Michael; Blass, Ulrich; Ackermann, Sonia; Ciobota, Valerian; Rosch, Petra; Tarcea, Nicolae; Popp, Jurgen; Majzlan, Juraj (The Clay Minerals Society, 2011)
    Iron oxides, typical constituents of many soils, represent a natural immobilization mechanism for toxic elements. Most iron oxides are formed during the transformation of poorly crystalline ferrihydrite to more crystalline ...
