Abstract Using the ESCA technique, core binding energies for Fe, Mg, Al, Si, and O have been obtained for a number of well-characterized silicate minerals. Surprisingly, we find no significant difference in binding energy between Fe 2+ and Fe 3+ in these silicates. O ls line widths for minerals with only one type of oxygen are generally narrower than those containing more than one type of oxygen, and there is a small difference in Al 2p binding energy for Al in four coordination and Al in six… CONTINUE READING
