Behavior of Volatiles in Arc Volcanism ; Geochemical and Petrologic evidence …

The transport of chemical elements by uprising magma is one of the fundamental processes by which material is recycled through subduction along convergent plate-boundaries. Obtaining quantitative information on the mass balance of volatile elements is hampered by their complex behavior in magmatic systems.
