14 p, 1.5 MB Weathering sequences of rock-forming minerals in a serpentinite : Influence of microsystems on clay mineralogy / Caillaud, J. (Université du Littoral Côte d'Opale. FRE 2816 CNRS. ELICO) ; Proust, D. (Hydrasa. Faculté des Sciences. UMR 6532 CNRS) ; Righi, D. (Hydrasa. Faculté des Sciences. UMR 6532 CNRS)
Under closed geochemical conditions, the weathering of a serpentinite rock composed of serpentine (70-85%) and magnesian chlorite (10-15%) associated with magnetite and chromite leads to the complete replacement of serpentine and chlorite by 2:1 layer silicates and produces new Fe oxides. [...]

11 p, 161.0 KB Clay profiling : The classification of montmorillonites / Emmerich, Katja (Forschungszentrum Karlsruhe. Competence Center for Material Moisture. University of Karlsruhe) ; Wolters, Felicitas ; Kahr, Guenter (Institute of Geotechnical Engineering. ETH Zurich) ; Lagaly, Gerhard (University of Kiel. Institute of Inorganic Chemistry)
Montmorillonites, with the general composition M (SiAl) [(Al,Fe) (Mg,Fe)] O(OH) where x = ξ = 0. 2a0. 6, x = y+z, and y«z, vary widely in composition and structure. The commonly used classification into five montmorilloniteand two beidellitegroups for the solid-solution sequence does not allow an unambiguous classification with respect to structural features and the resulting properties.
