FE3+/∑FE VS. FELα PEAK ENERGY FOR MINERALS AND GLASSES: RECENT ADVANCES WITH THE ELECTRON MICROPROBE

Fialin M.; Wagner C.; Métrich N.; Humler E.; Bézos A.; Galoisy L. (2001)

This paper describes a preliminary study that attempts to determine the oxidation state of Fe (Fe3+/∑Fe) with the electron microprobe (EMP) by measuring the self-absorption induced shift of the FeLα peak emitted from ...
MICROFACIES AND ORIGIN OF SOME ARCHEAN CHERTS (PILBARA, AUSTRALIA)

Orberger B.; Rouchon V.; Hashizume K.; Westall F.; De Vries S.T.; Pinti D.L.; Wagner C.; Wirth R. (2006)

Four cherts sampled in the East Pilbara craton (Western Australia) at Marble Bar (Towers Formation), North Pole Dome (Dresser and Apex Basalt Formation), and Kittys Gap (Panorama Formation) were studied for micro- and ...
QUANTITATIVE ELECTRON MICROPROBE ANALYSIS OF FE3+/∑FE: BASIC CONCEPTS AND EXPERIMENTAL PROTOCOL FOR GLASSES

Fialin M.; Bézos A.; Humler E.; Wagner C.; Magnien V. (2004)

The presence of an unfilled 3d electron shell in the transition metals of the first series is manifested in X-ray self-absorption effects that cause distortions in the L emission spectra. In particular, one observes peak ...
