After conversion of water to H2 gas with zinc for DH ratio determination, hydrogen gas can be absorbed by the zinc during cooling, resulting in H isotope fractionation. Thermal release and subsequent DH ratio determination ...

We present experimental results constraining water activity in H2O-N2 fluids containing 40–90 mol% water at pressures of 6–13 kbar and temperatures of 680–840 °C. In the experiments, the displacement of the brucite dehydration ...

The diffusion of water in dacitic and andesitic melts was investigated at temperatures of 1458 to 1858 K and pressures between 0.5 and 1.5 GPa using the diffusion couple technique. Pairs of nominally dry glasses and hydrous ...

On a cryogenic investigation solid H2S was successively observed after freezing CO2 in water-poor fluid inclusions in halite of Cambrian Siberian salts. Melting of a H2S solid phase occurs at nearly eutectic temperatures ...

Standard partial molal thermodynamic parameters for the aqueous chlorinated-ethylene species, perchloroethylene (PCE), trichloroethylene (TCE), 1,1-dichloroethylene (1,1-DCE), cis-1,2-dichloroethylene (cis-1,2-DCE), ...

The role of volatiles in island-arc magma generation is widely discussed in the geologic literature. Two of the most important volatile mineralizers are fluorine and chlorine, whose principal accumulator minerals in igneous ...

The structure of haploandesitic magma was modeled via in situ, high-temperature Raman spectroscopy along the join K2Si4O9-K2(KAl)4O9 from 25 to 1236°C. These glasses and melts consist of Q^4, Q^3, and Q^2 structural units. ...

The effect of H2O on harzburgite-saturated melts has been quantified with a series of hydrous and anhydrous melting experiments using a piston-cylinder device. Experimental conditions were 1.2–2.2 GPa and 1175–1500°C. Melt ...
