13 p, 1.2 MB Influence of synthesis conditions on the formation of a Kaolinitemethanol complex and simulation of its vibrational spectra / Matusik, Jakub (University of Science and Technology. Department of Mineralogy, Petrography and Geochemistry) ; Scholtzová, Eva (Slovak Academy of Sciences. Institute of Inorganic Chemistry) ; Tunega, Daniel (Universität für Bodenkultur. Institut für Bodenforschung)
Kaolinite is often used as a base for the synthesis of new organo-mineral nanomaterials designed for applications in industry and in environmental protection. To make the mineral structure more likely to interact with organic molecules, a kaolinite-methanol complex (KM) can be used. [...]

11 p, 1.1 MB Synthesis and properties of Sn-containing magadiite / Supronowicz, Wojciech (Carl von Ossietzky University. Industrial Chemistry II) ; Roessner, Frank (Carl von Ossietzky University. Industrial Chemistry II) ; Schwieger, Wilhelm (Universität Erlangen-Nürnberg. Lehrstuhl für Chemische Reaktionstechnik Friedrich-Alexander) ; Meilikhov, Mikhail (Universität strasse) ; Esken, Daniel (Universität strasse)
Hydrothermal syntheses of the magadiite, a layered silicate structure, were conducted in the presence of a heteroatom source (SnCl 5HO) with the intention of investigating its influence on the resulting material, as well as the possibility of isomorphous replacement of Si by Sn atoms in the above-mentioned structure.

13 p, 2.6 MB Mg-bentonite in the Parnaíba paleozoic Basin, northern Brazil / Da Paz, Simone Patrícia Aranha (UFPA - Universidade Federal do Pará. Laboratório de Caracterização Mineral) ; Angélica, Rômulo Simôes (UFPA - Universidade Federal do Pará. Laboratório de Caracterização Mineral) ; De Freitas Neves, Roberto (UFPA - Universidade Federal do Pará. Faculdade de Engenharia Química)
Bentonite deposits are rare in Brazil and most of their production comes from a single region. A new bentonite occurrence, the Formosa bentonite from northern Brazil, is described here. The occurrence is associated with altered Mesozoic volcanic rocks of the Parnaíba Sedimentary Basin, one of the largest continental flood basalt (CFB) provinces on Earth. [...]

13 p, 1.3 MB Mineralogical and physico-chemical characterizations of ferruginous beidellite-rich clay from Agadir basin (Morocco) / Bouna, L. (Université Cadi Ayyad) ; Rhouta, B. (Université Cadi Ayyad) ; Daoudi, L. (Université Cadi Ayyad) ; Maury, F. (Université de Toulouse) ; Amjoud, M. (Université Cadi Ayyad) ; Senocq, F. (Université de Toulouse) ; Lafont, M. C. (Université de Toulouse) ; Jada, A. (Institut de Sciences des Matériaux de Mulhouse) ; Aït Aghzzaf, A. (Université Cadi Ayyad)
The mechanism of formation of detrital, beidellite-rich clay occurring in the Agadir basin (Morocco) is well documented, but its detailed characterization is incomplete which limits its application. The aim of the present study was to provide further details of the mineralogical and physico-chemical characteristics of this clay. [...]

Department of Earth and Planetary Science) ; Wirth, Richard (GeoForschungsZentrum)
The thermal maturity of samples of the Posidonia Shale collected from the Hils Syncline, northern Germany, varies significantly as a function of location indicating variations in local history. Synchrotron X-ray diffraction was used to document the composition and the preferred orientation of four samples of the Posidonia Shale with different degrees of maturity (0. [...]
