The chemical and isotopic composition of fumarolic gases and spring discharges from Galeras Volcano, Colombia

Galeras fumarole discharges have been collected since its reactivation, in 1988, through December 1995. The gases are dominated by H 2O, CO 2, S (as SO 2 and H 2S) and HCl. The relative proportions of these gases classify them as ‘magmatic’. Thermodynamic equilibrium temperatures of the gases range...
