Sulfur K-edge XANES analysis of natural and synthetic basaltic glasses: Implications for S speciation and S content as function of oxygen fugacity
TL;DR: 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 transition from sulfide (S 2� ) to sulfate (S 6+ ) in silicate melts as mentioned in this paper.

An H 2 O–CO 2 mixed fluid saturation model compatible with rhyolite-MELTS
TL;DR: A thermodynamic model for estimating the saturation conditions of H2O-CO2 mixed fluids in multicomponent silicate liquids is described in this paper, where the model is restricted to natural composition liquids over the pressure range 0.3 GPa.

New experimental data and semi-empirical parameterization of H2O–CO2 solubility in mafic melts
TL;DR: In this article, a semi-empirical H2O-CO2 solubility model for mafic melts, which employs simplified concepts of gas-melt thermodynamics coupled with a parameterization of both chemical composition and structure of the silicate melt, is presented.
Journal ArticleDOI
Reconstructing the deep CO2 degassing behaviour of large basaltic fissure eruptions
TL;DR: In this article, the mass of volatiles degassed from volcanic eruptions is estimated by comparing the volatile concentrations in undegassed glassy melt inclusions with the volatile concentration in the degassed matrix glass.

Experimental Simulation of Closed-System Degassing in the System Basalt–H2O–CO2–S–Cl
TL;DR: In this article, an alternative experimental approach aimed at directly simulating decompression-driven, closed-system degassing of basaltic magma in equilibrium with an H^C^O^S^Cl fluid under oxidized conditions (fO2 of 1·0^2· 4l og units above the Ni^NiO buffer).

VOLATILECALC: a silicate melt-H 2 O-CO 2 solution model written in Visual Basic for excel
Sally Newman,Jacob B. Lowenstern +1 more
TL;DR: The VOLATILECALC solution models for the rhyolite-H2O-CO2 and basalt-H 2 O-CO 2 systems at magmatic temperatures and pressures below ∼ 5000 bar are presented in this paper.
Volatiles in subduction zone magmas : concentration and fluxes based on melt inclusion and volcanic gas data
TL;DR: In this paper, the fluxes of volatiles subducted back into the mantle along subduction zones and returned from the mantle to the surface reservoir via magmatism suggests that there is an approximate balance for structurally bound H2O and Cl.
