Recycling of Fluid Mobile Elements in Subduction Zones: Contraints from Lithium and Boron Isotopes

This study will utilise the special characteristics of boron and lithium isotopes, and improved analytical techniques to examine a number of specific processes/factors that control the cycling of fluid-mobile elements in subduction zones. This will enable us to: (I) better constrain the sources of individual components involved in the genesis of arc magmas, (ii) generate more accurate mass balance calculations at convergent plate margins, and (iii) have a greater understanding of how subduction process impact on evolution of the crustal and mantle systems, and the formation of economic ore-deposits.
