1 EVOLUTION OF MAGMATIC FLUIDS IN ACTIVE VOLCANIC HYDROTHERMAL SYSTEMS: A THERMODYNAMIC MODEL (EBEKO
Evolution of fluids in igneous and hydrothermal activity is a key point in understanding magmatic processes. Overview papers on melt inclusions and quench glasses [1, 2] contain a collection of 5000 reliable analyses of volatiles. A large database has been obtained on high-temperature (>700°C) hy...

Evolution of fluids in igneous and hydrothermal activity is a key point in understanding magmatic processes.
