Oxygen) is focused onto a polished target sample and a small amount of material is sputtered, typically with dimensions of 10–50 microns in diameter and less than 5 microns depth. Secondary ions are produced during sputtering and they are analyzed in the mass spectrometer (Ireland and Williams 2003). The SIMS technique is effectively non-destructive and ideal for analyzing complexly zoned zircon and for distinguishing the ages of inherited cores and magmatic and metamorphic overgrowths. , Williams et al.

Collectively, these improvements provide the opportunity to discriminate different magmatic episodes in the crystallization sequences of layered intrusions. , Ireland and Williams 2003; Nemchin et al. 2013). These in situ techniques allow for the determination of isotopic ratios from within single zones of crystals at scales of tens of microns that can target areas with distinctive textural, chemical, and isotopic signatures.
