- Abstract:
- Subduction is the fundamental process of mass transfer from crust to mantle. To model this process quantitatively requires knowledge of mineral-fluid partitioning of trace elements during dehydration of the subducted ocean crust. We propose a novel experimental technique for the direct determination of partition coefficients along the univariant curve amphibole-quartz-corundum-cpx-garnet(-rutile) in the system CMAS(Ti)-H2O. Coexisting fluid will be trapped as synthetic fluid inclusions in quartz, and corundum and analysed for trace elements using laser ablation ICP-MS. Residual garnet, amphibole and clinopyroxene will be analysed by LA-ICP-MS and SIMS. Our results will provide key data for quantitative modelling of the slab-to-mantle flux in subduction zones and the chemical evolution of dehydrating oceanic crust during subduction.
