An experimental study of trace element partitioning between zircon and melt as a function of oxygen fugacity
The partitioning of P, Sc, Ti, Sr, Y, Nb, the rare earth elements (REE), Hf, Ta, Th and U between zircon and a synthetic andesitic melt was determined as a function of oxygen fugacity (fO 2) over a range of fourteen log units, from QFM-8 to QFM+6 (where QFM is the quartz-fayalite-magnetite oxygen buffer) at ∼1300°C and 1atm, using SIMS and LA-ICP-MS. The partition coefficients of Ce and Eu were found to vary systematically with fO 2, relative to those of the other REE, producing Ce and Eu...[Show more]
