QUANTITATIVE DETERMINATION OF THE OXIDATION STATE OF IRON IN BIOTITE USING X-RAY PHOTOELECTRON SPECTROSCOPY: I. CALIBRATION

Raeburn S.P.; Ilton E.S.; Veblen D.R. (1997)

X-ray photoelectron spectroscopy (XPS) analyses of Fe(III)ΣFe were calibrated with nine single crystals of biotite of known Fe(III)ΣFe content. Peak shape parameters for the component Fe2+ and Fe3+ Fe 3p peaks were obtained ...
QUANTITATIVE DETERMINATION OF THE OXIDATION STATE OF IRON IN BIOTITE USING X-RAY PHOTOELECTRON SPECTROSCOPY: II. IN SITU ANALYSES

Raeburn S.P.; Ilton E.S.; Veblen D.R. (1997)

X-ray photoelectron spectroscopy (XPS) was used to determine Fe(III)ΣFe in individual biotite crystals in thin sections of ten metapelites and one syenite. The in situ XPS analyses of Fe(III)ΣFe in biotite crystals in the ...
THE CATALYTIC EFFECT OF SODIUM AND LITHIUM IONS ON COUPLED SORPTION-REDUCTION OF CHROMATE AT THE BIOTITE EDGE-FLUID INTERFACE

Ilton E.S.; Veblen D.R.; Moses C.O.; Raeburn S.P. (1997)

Large single crystals of biotite and near-endmember phlogopite were reacted with aqueous solutions bearing 20 μM Cr(VI) and different concentrations of NaCl, LiCl, RbCl, CsCl, NaClO4, and Na2SO4. Solutions were maintained ...
