Short summary
Here, we conducted spectroscopic measurements on high-pressure, high-temperature fluids and melts to study how halogens, in particular bromine, can be incorporated in subduction zone fluids and melts. We find that a gradual evolution of bromine speciation with liquid composition enables the incorporation of high amounts of Br in both phases. Thus, bromine and, by extension, chlorine are expected to be efficiently recycled from the slab towards the volcanic arc.
