Advances of ferrous and ferric Mössbauer recoilless fractions in minerals and glasses

Autor: Hongluo L. Zhang

Publikováno v: Geoscience Frontiers, Vol 13, Iss 2, Pp 101316-(2022)

Mossbauer spectroscopy has been used widely to characterize the ferric (Fe3+) and ferrous (Fe2+) proportions and coordination of solid materials. To obtain these accurately, the recoilless fraction is indispensible. The recoilless fractions (f) of ir

Determination of Fe3+/ΣFe of XANES basaltic glass standards by Mössbauer spectroscopy and its application to the oxidation state of iron in MORB

Autor: Hongluo L. Zhang, Katherine A. Kelley, Peat A. Solheid, Marc M. Hirschmann, Elizabeth Cottrell

Publikováno v: Chemical Geology. 479:166-175

To improve the accuracy of X-ray absorption near-edge structure (XANES) calibrations for the Fe3 +/ΣFe ratio in basaltic glasses, we reevaluated the Fe3 +/ΣFe ratios of glasses used as standards by Cottrell et al. (2009), and available to the commu

Accurate determination of Fe3+/∑Fe of andesitic glass by Mössbauer spectroscopy

Autor: Rebecca A. Lange, Anette von der Handt, Peat A. Solheid, Marc M. Hirschmann, Hongluo L. Zhang

Publikováno v: American Mineralogist. 100:1967-1977

To evaluate the accuracy of Fe3+ and Fe2+ ratios in silicate glasses determined by Mossbauer spectroscopy, we examine in detail the temperature (47–293 K) of Mossbauer spectra for two andesitic glasses, one quenched at 1 atm, 1400 °C (VF3) and the
