The mélange rises as diapirs into the overlying hot mantle wedge due to its buoyancy and low viscosity, which then melts along with the surrounding mantle rocks and eventually forms the arc magmas.

The study, resulting from a collaboration between the laboratory of Professor of Geology Claire Bucholz and UC Berkeley, has shown that the strontium isotopic compositions of island arc magmas ...
