Spectroscopic Methods in Mineralogy and Geology, Frank C. Hawthorne, ed. 1988),
contained a single chapter on X-ray absorption spectroscopy which reviewed aspects of …

The abundances of CO2, H2O, S and halogens dissolved in basaltic magmas are strongly
variable because their solubilities and ability to be fractionated in the vapor phase depend …

XANES analyses at the sulfur K-edge were used to determine the oxidation state of S
species in natural and synthetic basaltic glasses and to constrain the fO2 conditions for the …

Accurate estimates of the sulfur content in silicate melts at sulfide saturation are required to
explain magmatic processes such as the origin and budget of sulfur in some volcanic …

Experiment and observation have established the centrality of oxygen fugacity (f O 2) to
determining the course of igneous differentiation, and so the development and application of …

We experimentally investigated the effect of water on the sulfur concentration at sulfide
saturation (SCSS) in basaltic, andesitic, and rhyolitic melt compositions at 1250° C, 1 GPa …

The major magmatic volatile components—H2O, CO2, S, Cl, and F—play an important role
in the formation, evolution, and eruption of magma. Knowledge of magmatic concentrations …

Piston cylinder experiments are used to investigate the effect of oxygen fugacity (ƒO 2) on
sulphur speciation and phase relations in arc magmas at 0.5–1.5 GPa and 840–950° C. The …

Subduction zone magmas are more oxidised on eruption than those at mid-ocean ridges.
This is attributed either to oxidising components, derived from subducted lithosphere (slab) …

We have determined the chemical speciation of dissolved sulfur and the sulfur concentration
at fixed oxygen and sulfur fugacities for a wide range of silicate melt compositions (from Fe …
