Elemental and isotopic chemistry of the Uzon Caldera
The Uzon Caldera is an active As-Sb-Au epithermal system of the Kamchatka Peninsula, Far-East Russia. Using dD/d18O/d34S and dissolved ion chemistry, three thermal fluid types were distinguished at the surface as follows: 1) an acid sulfate type 2) an alkali chloride type and 3) a dilute type result...
