Monazite can be used for U–Pb and Th–Pb dating of a wide variety of rocks and geological processes, particularly metamorphism. In many instances ion microprobe analysis is the preferred method for dating monazite, combining good analytical precision with μm-scale spatial resolution. However, ion microprobe dates can be compromised by matrix effects on the ionisation efficiencies of different secondary...
Xenotime is a widely occurring mineral that is amenable to U–Pb and Th–Pb dating but often is found as micrometre-sized crystals that can only be dated by in situ microanalytical techniques. Determining accurate ages for Phanerozoic samples, and assessing concordance in older samples, requires accurate determination of Pb/U and Pb/Th; however, ion microprobe data for these ratios are affected by the...
