Fumarole compositions and mercury emissions from the Tatun Volcanic Field, Taiwan: Results from multi-component gas analyser, portable mercury spectrometer and direct sampling techniques

Abstract:

Gas emissions from Tatun volcanic group, northern Taiwan, were studied for the first time using a multi-component gas analyser system (Multi-GAS) in combination with Giggenbach flask methods at fumaroles and mud pools at Da-you-keng (DYK) and Geng-tze-ping (GZP). CO2/S molar ratios observed at DYK ranged from 3-17, similar ratios were observed using a Multi-GAS sensor box of 8-16. SO2 at GZP was low, higher concentrations were observed at DYK where SO2/H2S ratios were close to 1 for both meth...
