| Abstract: | A method is presented for the determination of rare earth elements (REE) in zircon (ZrSiO4) using a multi-collector equipped ion-microprobe operating at moderately high mass resolution (M/ΔM ? 3900). The low abundance light REE (La-Eu) were measured simultaneously in six ion counting electron multipliers, reducing analytical time to less than half of that in a monocollection routine. Effective mass filtering, moderate energy filtering and careful set up of detector parameters in order to minimise background counts, yielded a highly coherent set of analyses from the 91500 zircon reference sample. |
