TL;DR: The accumulation chamber methodology allows one to obtain reliable values of the soil CO2 flux in the range 0.2 to over 10 000 g m−2 d−1, as proven by both laboratory tests and field surveys in geothermal and volcanic areas as discussed by the authors.

TL;DR: Variations in δD and δ18O values with H2O contents and outlet temperatures indicate that the fumaroles of La Fossa crater have discharged mixtures of magmatic water and marine hydrothermal water, since 1979.

TL;DR: In a recent survey of the spring waters of the Genova province, many neutral Mg-HCO3 waters and some high-pH, Ca-OH waters were found in association with serpentinites.

TL;DR: More than 200 chemical and isotope analyses of fumarolic fluids collected at the Fossa Grande crater, Vulcano Island, during the 1980s show that the main process controlling these fluids is mixing between the gas released by a magma body and the vapour produced through evaporation of brines of marine origin this article.

TL;DR: The detailed analysis of the craters of hydrothermal eruptions and related products present on Nisyros Island demonstrates the ephemerality of these morphological forms as mentioned in this paper. In other words, the mere recognizable existence of the Craters and associated deposits implies recency of Hydrothermal activity, and the minimum temperature required to cause the explosive phenomenon and, possibly, the depth of the reservoir (which can be evaluated on the basis of the correlation between the diameter of the crater and the depths of the explosion as proposed by Fytikas and Marinelli, 1976) are
