| Abstract | The source of volatiles such as Cl, S and CO2 in geothermal systems is an object of frequent debate. Early experiments concluded that they could be derived solely from water-rock interaction. Others infer that some component of magmatic input is necessary. We have conducted experiments to measure the volatiles released during progressive heating of a greywacke typical of the basement rock of the Taupo Volcanic Zone. |
