Abstract. This review focuses on the solubility, origin, abundance, and degassing of carbon dioxide (CO2) in magma–hydrothermal systems, with applications for those workers interested in intrusion-related deposits of gold and other metals. The solubility of CO2 increases with pressure and magma alkalinity. Its solubility is low relative to that of H2O, so that fluids exsolved deep in the crust tend to have high CO2/H2O compared with fluids evolved closer to the surface. Similarly, CO2/H2O will… Expand
Fluids associated with carbonatitic magmatism: A critical review and implications for carbonatite magma ascent
Abstract Carbonatites are formed from volatile-rich melts, commonly associated with a characteristic hydrothermal footprint. However, studies of their fluid inclusions are relatively scarce andExpand
Italian carbonatite system: From mantle to ore-deposit
Abstract A new discovery of carbonatites at Pianciano, Ficoreto and Forcinelle in the Roman Region demonstrates that Italian carbonatites are not just isolated, mantle xenoliths-bearing, primitiveExpand
Hydrothermal Fluids of Magmatic Origin
Hydrothermal fluids are natural heated water solutions wherein variety of elements, compounds and gases may be dissolved. They are generated by diverse crustal and mantle geological processesExpand
Modification of fumarolic gases by the ice-covered edifice of Erebus volcano, Antarctica
Abstract The chemistry of gases measured in ice caves and from warm geothermal ground at Erebus volcano, Antarctica, shows that gas emissions are dominated by air, with varying amounts of addedExpand
The oxidation state, and sulfur and Cu contents of arc magmas: implications for metallogeny
Abstract Global data for measured Fe2O3/FeO ratios and Cu contents in unaltered volcanic and intrusive arc rocks indicate that, on average, they are slightly more oxidized than other magmas derivedExpand
The effect of pressure on sulphur speciation in mid- to deep-crustal arc magmas and implications for the formation of porphyry copper deposits
Piston cylinder experiments are used to investigate the effect of oxygen fugacity (ƒO2) on sulphur speciation and phase relations in arc magmas at 0.5–1.5 GPa and 840–950 °C. The experimentalExpand
Copper partitioning between felsic melt and H2O–CO2 bearing saline fluids
Abstract Analysis of fluid inclusions from porphyry copper deposits reveals that magmatic vapor and brine are vital for the removal of copper from arc magmas and its transport to the site of oreExpand
Gold speciation and transport in geological fluids: insights from experiments and physical-chemical modelling
Abstract This contribution provides an overview of available experimental, thermodynamic, and molecular data on Au aqueous speciation, solubility, and partitioning in major types of geological fluidsExpand
Evolution of Arc Magmas and their Volatiles
Of the volumetrically significant magma types, those emplaced in arcs at plate convergence zones are typically richest in dissolved volatiles (H 2 O, CO 2 , and S species). These volatiles are mostlyExpand
The geochemical modelling of emergent life from submarine hydrothermal environments
Hydrothermal systems may have been more widespread in the Hadean due to a greater heat flux. To investigate this possibility, and unravel the mechanism(s) by which the pH of high-temperature ventExpand
