TL;DR: The chemical and isotopic compositions of fumarolic gases from Nisyros, Greece, indicate that both arc-type magmatic water and local seawater feed the hydrothermal system as discussed by the authors.

TL;DR: In this article, the theoretical concentration of Ca, Mg, HCO3, SO4, F and their complexes in aqueous solutions in equilibrium with a mineral assemblage made up of calcite, dolomite, anhydrite and fluorite has been calculated at temperatures between 0 and 150°C, atPco2; in the 0.1-100 bar interval and for total molality of mobile species Na and CI ranging between 0.0001 and 0.3.

TL;DR: A comparative study of soil CO2 flux measured by five groups (Groups 1-5) at the IAVCEI-CCVG Eighth Workshop on Volcanic Gases on Masaya volcano, Nicaragua, is presented in this article.

TL;DR: The chemical and isotopic compositions of volcanic and hydrothermal gases reflect processes related to volatile sources and transport from the magma to the surface as mentioned in this paper, and they provide important information on the ultimate sources of volcanic emissions in terms of mantle, crust, and subducted materials.

TL;DR: In this article, both the shallow and deep fluxes of CO2 dissolving in the shallow groundwaters of the volcanic areas of Amiata, Vulsini-Vico-Sabatini, Albani, Roccamonfina, Vesuvio, Vulture, and Etna were evaluated by partitioning the composed population of total dissolved inorganic carbon in two individual populations and subsequent subtraction of local background population.
