Effect of SiO2, total FeO, Fe3+/Fe2+ and alkali elements in basaltic glasses on mid-infrared spectra

Dufresne, Celeste D.M.; King, Penelope; Dyar, M D; Dalby, Kim N.


A suite of basaltic glasses were examined to determine how subtle compositional changes affect mid-infrared spectra (650 to 5400 cm-1). Glasses with different SiO2, FeOtotal, Fe 3+/Fe2+, and alkali contents were synthesized in a gas-mixing furnace and analyzed using electron probe microanalysis, Mössbauer spectroscopy, and micro-reflectance Fourier transform infrared spectroscopy. The major mid-infrared spectral feature in silicate glasses is a broad peak located at ∼900 to 1100 cm-1 arising...[Show more]
