Volcanic gases puffing out of the ground at the Wai-O-Tapu geothermal fields in New Zealand. Main gases coming out of this vent are water vapour and carbon dioxide, however, many other gases can also be present in trace amounts, but this chemistry is dependent on the geological environment. Sulphur is definitely present in this mixture as can be observed by the yellow sulphur crystals forming around the mouth of the vent. -- source link
