摘要
Gaseous sulfur compounds are critical climate active volatile components released by volcanoes. Volcanic eruptions can emit massive amounts of H2S and SO2 into the atmosphere, which react with oxygen and H2O to sulfuric acid. Formation of H(2)SO4 aerosols, which have on a geological timescale short-term residence times of month or years, may have global climatic impact. The phase stability of sulfur-bearing minerals such as anhydrite in erupting magmas may be a key controlling factor limiting SO2 emission during subaerial volcanic activity (Huang and Keppler, January 2015 issue of American Mineralogist).
