Trace element maps of four zircon reference materials using LA-ICP-MS and FIB-SEM-based TOF-SIMS

This dataset provides high spatial resolution trace element maps of four zircon reference materials: 91500 (Ontario, Canada), Mud Tank (Northern Territory, Australia), Temora (New South Wales, Australia), and Plešovice (South Bohemia, Czech Republic), as well as zircon crystals from the Mount Dromedary/Gulaga Igneous Complex, New South Wales, Australia. Qualitative, sub-micrometre resolution focused ion beam scanning electron microscope (FIB-SEM) based time-of-flight secondary ion mass spectrometry (TOF-SIMS) isotope maps and associated spectra are presented. Five-micrometre resolution raster isotope maps created from laser ablation-inductively coupled-mass spectrometry line scans are also presented. These data are useful for assessing trace element variation at very fine scale in zircon reference materials and ‘unknown’ zircon crystals. The data also confirm the usefulness of TOF-SIMS in this novel application to zirconology.
