2015/9/10
A compendium of diffusion measurements and their Arrhenius equations for water, carbon dioxide, sulfur, fluorine,
and chlorine in silicate melts similar in composition to natural igneous rocks is pre...
A model of sulphur solubility for hydrous mafic melts: application to the determination of magmatic fluid compositions of Italian volcanoes
sulphur hydrous basalts volcanic gas
2015/9/10
We present an empirical model of sulphur solubility that allows us to calculate f S2 if P, T, fO2 and the melt composition,
including H2O and S, are known. The model is calibrated against three main ...
Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes

CO2 H2O solubility mixed fluid silicate melt experimental data
2015/9/10
The effect of pressure, temperature, and melt composition on CO2 and H2O solubilities in aluminosilicate
melts, coexisting with CO2-H2O fluids, is discussed on the basis of previously published and n...
Polymerisation, basicity, oxidation state and their role in ionic modelling of silicate melts
polymerisation basicity oxidationstate water speciation Temkin model
2015/9/10
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...
Chemical interactions and configurational disorder in silicate melts
silicate melts structure entropy unmixing
2015/9/10
The Thermodynamics of quasi-chemical and polymeric models are briefly reviewed. It is shown that the two
classes are mutually consistent, and that opportune conversion of the existing quasi-chemical ...
Acid-base properties and structons: towards a structural model for predicting the thermodynamic properties of silicate melts
silicate melt acid-base oxide melt thermodynamic properties
2015/9/10
Phase equilibrium relationships in igneous systems can be estimated using empirical mathematical models based on
multi-component regular solution formulae. Although these provide useable results with...

shock-produced melts system impact processes
2014/4/8
We observed micrometer-sized grains of wadsleyite, a high-pressure phase of (Mg,Fe)2SiO4,
in the recovery products of a shock
experiment. We infer these grains crystallized from shock-generated melt...
