Cl, F, and SO2 in Central American volcanic gases

Document Type


Publication Date



The Cl, F, SO2 contents and Cl/F and Cl/SO4 ratios in Central American volcanic gases are examined. 103−105 tons SO2 per day are given off during eruptions and 102 when a prominent vapor cloud persists between eruptive periods. Data regarding Cl and F and SO4 from leachates, condensates, and incrustations are compared. Our data suggest circumpacific volcanoes are SO2 poor relative to Cl and may be F poor although F is higher in basaltic Central American volcanoes than others.
