In order to describe and quantify the reactivity of silicate melts, the ionic notation provided by the Temkin formalism has been historically accepted, giving rise to the study of melt chemical equil...
The goal of this study is to explore the relationship between the oxygen fugacity of a melt and the Fe3+/FeTotal of plagioclase crystals produced from the melt. If the relationship between the two can...
Abstract: Glauconite from the oxidized and reduced zones of soil-geologic columns at two Coastal Plain sites, one in Maryland and one in New Jersey, was examined by M鰏sbauer spectroscopy. The data ind...
The investigations of Si 1s and 2p photoelectron spectra of a poly-Si plate with natural oxide layers based on high energy excitation using X-ray tubes with three kinds of target (Mg Kα, Zr Lα and Ag ...
Abstract: Reduction of structural Fe in Na-exchanged dioctahedral smectites decreases swellability in water, but because clay interlayers also collapse in the process the concomitant effect on surface...
XANES measurements on gold-bearing arsenian pyrite from the Twin Creeks Carlin-type gold and Au and arsenic is present at As . Au is attributed deposits show that gold is present as both Au to su...
Aqueous gels of unaltered (oxidized) and chemically reduced ferruginous smectite (SWa-1 from the Source Clays Repository of The Clay Minerals Society) were characterized by transmission electron micro...
The effect of Fe oxidation state on the specific surface area, Sm, of nontronite was studied using the <2-祄, Na+-saturated fraction of the SWa-1 and Garfield nontronite reference clays. The reduction ...
Three montmorillonites and a nontronite were reduced by sodium dithionite to obtain different amounts of Fe2+ in their octahedral sites. The mass ratio of water to clay, mw/mc, was determined as a fun...
