Abstract

Volcanic arcs can produce large eruptions. However, there are many unknowns about how the magma at volcanic arcs is formed. In particular, it is unclear whether these silicic magmas form deep in the mantle or shallow in the crust. This study will analyze trace elements using cutting edge techniques to explore the conditions of melt formation. The results will be important for understanding the causes of catastrophic…
