PB6016 Geochemistry of Geothermal Gas
This lecture studies characteristics of gas commonly occurred in geothermal system (e.g. CO2, H2, He, Ar, etc.). their ocurrences and application in a geothermal system. Gas geothermometer and source of geothermal fluids assessed from gas content are given in this lecture. This lecture also introduces several methods regarding to gas used during geothermal exploration. The lecture also reviews a vapour dominated geothermal system, especially on how the system occurred and changed.
