Vapour-phase crystallisation of silica from SiF4-bearing volcanic gases

Vapour-phase crystallisation of silica from SiF4-bearing volcanic gases

Thermodynamic modelling of magmatic gases shows that SiF4 may be an important F-bearing species at the high
 pressures typical of magma reservoirs. Upon decompression during degassing, SiF4 will react with water vapour
 to form HF and silica. Common magmatic gases of high-T fumaroles...
