Stable isotope variations in arc lavas

Subduction zones are unique tectonic setting in our solar system that facilitate crustal recycling and play a key role in the generation of continental crust, element transport and volatile cycling. The geochemistry of arc lavas produced at subduction zones has long been used to untangle the complex...

This chapter reviews the rapidly evolving field of stable isotope geochemistry as applied to arc lavas. The entire periodic table is analytically accessible, however, there is great disparity in our understanding of individual isotope systems in arcs.
