Summary

The iron environment and oxidation state has been determined by XANES spectroscopy in a montmorillonite sample from Gola del Furlo (Marche, Italy). A comparison with the XANES spectra of Fe2− in a natural hematite from Elba (Italy) and of Fe 21 in a synthetic Fe[C03] (the fine structures in the spectra of which have also been clarified in detail on the basis of the known crystal structures) permits recognizing that in this sheet silicate Fe is mostly in the trivalent oxidation state and in a distorted octahedral coordination. Mössbauer spectroscopy confirms the XANES assignment, but it also shows that minor octahedral Fee+ is present besides the predominant octahedral Fe3—.

Zusammenfassung

Synchroton Radiation XANES und Mössbauer-Studien zur Vertielung des Eisens im Montmorillonit aus Gola del Furlo(Marche, Italien) Die Verteilung und die Oxidationsstufe des Eisens eines Montmorillonites aus Gola del Furlo (Marche, Italien) wurden untersucht. Ein Vergleich der XANES Spektren dieses Schichtsilikates mit denen von FeFe3+ eines natürlichen Hämatites von Elba (Italien) und von Fe2+ eines synthetischen Fe[C03], wobei die Details der Spektren auf Grund der Kenntnis der bekannten Kristallstruktur geklärt werden konnten, zeigt, daß Eisen großteils in dreiwertiger Form und in verzerrter oktaedrischer Koordination vorliegt. Mössbauer-Studien bestätigen die Ergebnisse der XANES Untersuchungen, zeigen aber auch, daß untergeordnet Fe e+ an Stelle von Fe3+ in der oktaedrischen Position eingebaut wird.
